Observe the following before start-
ing off in the vehicle to ensure
safety of driving.

Installing floor mats

WARNING

Observe the following precautions.

Failure to do so may cause the driver’s

floor mat to slip, possibly interfering with

the pedals while driving. An unexpect-

edly high speed may result or it may

become difficult to stop the vehicle. This

could lead to an accident, resulting in

death or serious injury.

■

●

Do not use floor mats designed for

other models or different model year

vehicles, even if they are Lexus Genu-

ine floor mats.

●

Only use floor mats designed for the

driver’s seat.

●

Always install the floor mat securely

using the retaining hooks (clips) pro-

vided.

●

Do not use two or more floor mats on

top of each other.

●

Do not place the floor mat bot-

tom-side up or upside-down.

■

Before driving

●

before driving.

Correct driving posture

WARNING

■

For safe driving

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

Do not adjust the position of the

driver’s seat while driving.

Doing so could cause the driver to lose

control of the vehicle.

●

Do not place a cushion between the

driver or passenger and the seatback.

A cushion may prevent correct pos-

ture from being achieved, and reduce

the effectiveness of the seat belt and

head restraint.

●

Do not place anything under the front

seats.

Objects placed under the front seats

may become jammed in the seat

tracks and stop the seat from locking in

place. This may lead to an accident

and the adjustment mechanism may

also be damaged.

●

Always observe the legal speed limit

when driving on public roads.

●

When driving over long distances, take

regular breaks before you start to feel

tired.

Also, if you feel tired or sleepy while

driving, do not force yourself to con-

tinue driving and take a break immedi-

ately.

Seat belts

Make sure that all occupants are
wearing their seat belts before driv-
ing the vehicle.

WARNING

Observe the following precautions to

reduce the risk of injury in the event of

sudden braking, sudden swerving or an

accident.

Failure to do so may cause death or seri-

ous injury.

■

Wearing a seat belt

●

Ensure that all passengers wear a seat

belt.

●

Always wear a seat belt properly.

●

Each seat belt should be used by one

person only. Do not use a seat belt for

more than one person at once, includ-

ing children.

●

Lexus recommends that children be

seated in the rear seat and always use

a seat belt and/or an appropriate child

restraint system.

●

To achieve a proper seating position,

do not recline the seat more than nec-

essary. The seat belt is most effective

when the occupants are sitting up

straight and well back in the seats.

●

Do not wear the shoulder belt under

your arm.

●

Always wear your seat belt low and

snug across your hips.

●

When using the rear center seat seat

belt, check that the portion

in the

illustration is buckled.

If not buckled, make sure to buckle it

before using the seat belt.

■

Pregnant women

Obtain medical advice and wear the seat

belt in the proper way. (



P.29)

Women who are pregnant should posi-

tion the lap belt as low as possible over

the hips in the same manner as other

occupants, extending the shoulder belt

completely over the shoulder and avoid-

ing belt contact with the rounding of the

abdominal area.

If the seat belt is not worn properly, not

only the pregnant woman, but also the

fetus could suffer death or serious injury

as a result of sudden braking or a colli-

sion.

1-1. For safe use

For
safety

and
security



Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with the
neck or slide off the shoulder.



Position the lap belt as low as possi-
ble over the hips.



Adjust the position of the seatback.
Sit up straight and well back in the

Seat belt damage and wear

●

Do not damage the seat belts by allow-

ing the belt, plate, or buckle to be

jammed in the door.

●

Inspect the seat belt system periodi-

cally. Check for cuts, fraying, and loose

parts. Do not use a damaged seat belt

until it is replaced. Damaged seat belts

cannot protect an occupant from

death or serious injury.

●

Ensure that the belt and plate are

locked and the belt is not twisted.

If the seat belt does not function cor-

rectly, immediately contact your Lexus

dealer.

●

Replace the seat assembly, including

the belts, if your vehicle has been

involved in a serious accident, even if

there is no obvious damage.

●

Do not attempt to install, remove,

modify, disassemble or dispose of the

seat belts. Have any necessary repairs

carried out by your Lexus dealer. Inap-

propriate handling may lead to incor-

rect operation.

Correct use of the seat belts

1-1. For safe use

To fasten the seat belt, push the
plate into the buckle until a click
sound is heard.

To release the seat belt, press the
release button .

■

Emergency locking retractor (ELR)

The retractor will lock the belt during a sud-

den stop or on impact. It may also lock if you

lean forward too quickly. When the seat belt

locks, pull the belt strongly and then release

the belt, then a slow and easy pulling will

allow the belt to extend.

■

Automatic locking retractor (ALR)

When a passenger’s shoulder belt is com-

pletely extended and then retracted even

slightly, the belt is locked in that position and

cannot be extended. This feature is used to

hold the child restraint system (CRS) firmly.

To free the belt again, fully retract the belt

and then pull the belt out once more.

WARNING

■

Using a seat belt extender

Observe the following precautions to

reduce the risk of injury in the event of

sudden braking, sudden swerving or an

accident.

Failure to do so may cause death or seri-

ous injury.

●

Do not wear the seat belt extender if

you can fasten the seat belt without the

extender.

●

Do not use the seat belt extender

when installing a child restraint system

because the belt will not securely hold

the child restraint system, increasing

the risk of death or serious injury in the

event of an accident.

●

The personalized extender may not be

safe on another vehicle, when used by

another person, or at a different seat-

ing position other than the one origi-

nally intended.

NOTICE

■

When using a seat belt extender

When releasing the seat belt, press on

the buckle release button on the

extender, not on the seat belt.

This helps prevent damage to the vehicle

interior and the extender itself.

Fastening and releasing the seat
belt

For
safety

and
security

Push the seat belt shoulder anchor
down while pressing the release
button .

Push the seat belt shoulder anchor
up while pressing the release but-
ton .

Move the height adjuster up and down as
needed until you hear a click.

When the vehicle is subjected to a
severe frontal or side impact or roll-
over, the pretensioners retract the seat
belts of the front seats and rear outer
seats to securely restrain the occu-
pants.

The pretensioners will not operate in minor
frontal or side impacts, or rear impacts.

■

Replacing the belt after the preten-

sioner has been activated

If the vehicle is involved in multiple colli-

sions, the pretensioner will activate for the

first collision, but will not activate for the

second or subsequent collisions.

■

PCS-linked control

If the PCS (Pre-Collision System) deter-

mines that the possibility of a collision with a

vehicle is high, the seat belt pretensioners

will be prepared to operate.

anchor height (front seats)

WARNING

■

Adjustable shoulder anchor

Always make sure the shoulder belt is

positioned across the center of your

shoulder. The belt should be kept away

from your neck, but not falling off your

shoulder. Failure to do so could reduce

the amount of protection in an accident

and cause death or serious injuries in the

event of a sudden stop, sudden swerve or

accident.

Seat belt pretensioners (front
and outboard rear seats)

WARNING

■

Seat belt pretensioners

Observe the following precautions to

reduce the risk of injury in the event of

sudden braking or an accident.

Failure to do so may result in death or

serious injury.

●

Do not place anything, such as a cush-

ion, on the front passenger’s seat.

Doing so will disperse the passenger’s

weight, which prevents the sensor

from detecting the passenger’s weight

properly. As a result, the seat belt pre-

tensioner for the front passenger’s seat

may not operate in the event of a colli-

sion.

●

If a pretensioner has operated, the

SRS warning light will illuminate. In this

situation, the seat belt cannot be used

and must be replaced by your Lexus

dealer.

SRS airbags

The SRS airbags deploy when the vehicle is subjected to certain types of
severe impact that may cause significant injury to the occupants. The airbags
work together with the seat belts to help reduce the risk of death or serious
injury.

SRS airbag system

1-1. For safe use

For safety and security

Your vehicle is equipped with ADVANCED AIRBAGS designed based on US
motor vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtained from the sensors, etc.,
shown in the system components diagram above. This information includes crash
severity and occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain the motion of
the occupants.

■

If the SRS airbags deploy (inflate)

●

Slight abrasions, burns, bruising, etc., may

be sustained from SRS airbags, due to the

extremely high speed of deployment

(inflation) by hot gases.

●

A loud noise and white powder will be

emitted.

●

Parts of the airbag module (steering

wheel hub, airbag cover and inflator) as

well as the parts around the airbags may

be hot for several minutes. The airbag

itself may also be hot.

●

The windshield may crack.

●

The hybrid system will be stopped and

fuel supply to the engine will be stopped.

Vehicles with Safety Connect: If any of

the following situations occur, the system

is designed to send an emergency call to

the response center, notifying them of the

vehicle’s location (without needing to

push the “SOS” button) and an agent will

attempt to speak with the occupants to

ascertain the level of emergency and

assistance required. If the occupants are

unable to communicate, the agent auto-

matically treats the call as an emergency

and helps to dispatch the necessary

emergency services. (

WARNING

■

SRS airbag precautions

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

The driver and all passengers must

wear their seat belts correctly.

The SRS airbags are supplemental

devices to be used with the seat belts.

●

The SRS driver airbag deploys with

considerable force, and can cause

death or serious injury, especially if the

driver is very close to the airbag. The

National Highway Traffic Safety

Administration (NHTSA) advises:

Since the risk zone for the driver’s airbag
is the first 2 - 3 in. (50 - 75 mm) of infla-
tion, placing yourself 10 in. (250 mm)
from your driver airbag provides you with
a clear margin of safety. This distance is
measured from the center of the steering
wheel to your breastbone. If your current
driving position places you less than 10
in. (250 mm) away from the driver air-
bag, you can change your driving posi-
tion in several ways:
• Move your seat to the rear as far as

possible while still being able to reach

the pedals comfortably.

1-1. For safe use

WARNING

• Slightly recline the seatback. Although

vehicle designs vary, many drivers can

achieve the 10 in. (251 mm) distance,

even with the driver seat all the way

forward, simply by reclining the seat-

back somewhat. If reclining the seat-

back makes it hard to see the road,

raise yourself by using a firm, non-slip-

pery cushion, or raise the seat if your

vehicle has that feature.

• If your steering wheel is adjustable, tilt

it downward. This points the airbag

toward your chest instead of your head

and neck. The seat should be adjusted

as recommended by the NHTSA,

while still being able to control the

vehicle with the pedals and steering

wheel, and maintaining your view of

the instrument panel controls.

●

If a seat belt extender has been con-

nected to the front passenger seat belt

buckle but the latch plate of the front

passenger seat belt has not been fas-

tened to the seat belt extender, the

SRS airbag system will judge that the

front passenger is wearing the seat

belt even though the seat belt has not

been fastened. In this case, the SRS

front airbags for the front passenger

may not deploy correctly in a collision,

resulting in death or serious injury. Be

sure to wear the seat belt correctly

when using a seat belt extender.

●

The SRS front passenger airbag

deploys with considerable force, and

can cause death or serious injury,

especially if the front passenger is very

close to the airbag. The front passen-

ger seat should be positioned as far

possible from the airbag with the seat-

back adjusted so that the passenger is

sat upright.

●

Improperly seated and/or restrained

infants and children can be killed or

seriously injured by a deploying airbag.

An infant or child who is too small to

use a seat belt should be properly

secured using a child restraint system.

Lexus strongly recommends that all

infants and children be placed in the

rear seats of the vehicle and properly

restrained. The rear seats are safer for

infants and children than the front pas-

senger seat. (



P.45)

●

Do not sit on the edge of the seat or

lean against the dashboard.

●

Do not allow a child to stand in front of

the SRS front passenger airbag or sit

on the lap of a front passenger.

●

Front seat occupants should never

hold items on their lap.

1-1. For safe use

For
safety

and
security

WARNING

●

Do not lean against the door, roof side

rail, or front, side, or rear pillar.

●

Do not allow anyone to kneel on a seat

toward the door or put their head or

hands outside the vehicle.

●

Do not attach anything to or lean any-

thing against areas such as the dash-

board, steering wheel pad and lower

portion of the instrument panel.

●

Do not attach anything to areas such

as the doors, windshield, side windows,

front or rear pillars, roof side rails and

assist grips.

●

Do not hang coat hangers or other

hard objects on the coat hooks. These

items could become projectiles if the

SRS curtain shield airbags deploy, pos-

sibly leading to death or serious injury.

●

If a vinyl cover is attached to the area

where the SRS knee airbag deploys,

be sure to remove it.

●

Do not use seat accessories which

cover the parts from which the SRS

airbags deploy, as they may interfere

with inflation of the SRS airbags. Such

accessories may prevent the SRS air-

bags from deploying correctly, may

disable the system or cause the SRS

airbags to inflate unintentionally, possi-

bly resulting in death or serious injury.

●

Do not strike or apply significant force

to the SRS airbag system components,

front doors or their surrounding area.

Doing so may cause the SRS airbags

to malfunction.

●

Do not touch any components of the

SRS airbags immediately after the SRS

airbags have deployed (inflated) as

they may be hot.

●

If breathing becomes difficult after the

SRS airbags have deployed, open a

door or window to allow fresh air in, or

leave the vehicle if it is safe to do so.

Wash off any residue as soon as possi-

ble to prevent skin irritation.

1-1. For safe use

WARNING

●

If a part where an SRS airbag is stored

is damaged or cracked, have it

replaced by your Lexus dealer.

●

Do not place anything, such as a cush-

ion, on the front passenger’s seat.

Doing so will disperse the passenger’s

weight, which prevents the sensor

from detecting the passenger’s weight

properly. As a result, the SRS front air-

bags for the front passenger’s seat may

not deploy in the event of a collision.

■

Modification and disposal of SRS air-

bag system components

Do not dispose of your vehicle or per-

form any of the following modifications

without consulting your Lexus dealer.

The SRS airbags may malfunction or

deploy unintentionally, possibly leading

to death or serious injury.

Front passenger occupant classifica-

tion system precautions

Observe the following precautions

regarding the front passenger occupant

classification system.

Failure to do so may cause death or seri-

ous injury.

●

Wear the seat belt properly.

●

Make sure the front passenger’s seat

belt plate has not been left inserted

into the buckle before someone sits in

the front passenger seat.

●

Make sure the “AIR BAG OFF” indica-

tor light is not illuminated when using

the seat belt extender for the front pas-

senger seat. If the “AIR BAG OFF”

indicator light is illuminated, discon-

nect the extender tongue from the seat

belt buckle, and reconnect the seat

belt. Reconnect the seat belt extender

after making sure the “AIR BAG ON”

indicator light is illuminated. If you use

the seat belt extender while the “AIR

BAG OFF” indicator light is illumi-

nated, the SRS airbags for the front

passenger will not activate, which

could cause death or serious injury in

the event of a collision.

●

Do not apply a heavy load to the front

passenger seat or equipment (e.g.

seatback pocket).

●

Do not put weight on the front passen-

ger seat by putting your hands or feet

WARNING

●

Do not let a rear passenger lift the

front passenger seat with their feet or

press on the seatback with their legs.

●

Do not put objects under the front pas-

senger seat.

●

Do not recline the front passenger

seatback so far that it touches a rear

seat. This may cause the “AIR BAG

OFF” indicator light to be illuminated,

which indicates that the SRS airbags

for the front passenger will not activate

in the event of a severe accident. If the

seatback touches the rear seat, return

the seatback to a position where it

does not touch the rear seat. Keep the

front passenger seatback as upright as

possible when the vehicle is moving.

Reclining the seatback excessively

may lessen the effectiveness of the

seat belt system.

●

If an adult sits in the front passenger

seat, the “AIR BAG ON” indicator light

is illuminated. If the “AIR BAG OFF”

indicator is illuminated, ask the passen-

ger to sit up straight, well back in the

seat, feet on the floor, and with the seat

System malfunction

: The system judges a person of adult size as an adult. When a smaller adult sits in the

front passenger seat, the system may not recognize them as an adult depending on their
physique and posture.

: In the event the front passenger is wearing a seat belt.

: In the event the front passenger does not wear a seat belt.

: For some children, child in seat, child in booster seat or child in convertible seat, the sys-

tem may not recognize them as a child. Factors which may affect this can be the phy-
sique or posture.

: Never install a rear-facing child restraint system on the front passenger seat. A for-

ward-facing child restraint system should only be installed on the front passenger seat
when it is unavoidable. (

Exhaust gas precautions

Harmful substance to the human
body is included in exhaust gases if
inhaled.

WARNING

Exhaust gases include harmful carbon

monoxide (CO), which is colorless and

odorless. Observe the following precau-

tions.

Failure to do so may cause exhaust gases

enter the vehicle and may lead to an

accident caused by light-headedness, or

may lead to death or a serious health

hazard.

■

Important points while driving

●

Keep the back door closed.

●

If you smell exhaust gases in the vehi-

cle even when the back door is closed,

open the windows and have the vehi-

cle inspected at your Lexus dealer as

soon as possible.

■

When parking

●

If the vehicle is in a poorly ventilated

area or a closed area, such as a

garage, stop the hybrid system.

●

Do not leave the vehicle with the

hybrid system on for a long time.

If such a situation cannot be avoided,

park the vehicle in an open space and

ensure that exhaust fumes do not enter

the vehicle interior.

●

Do not leave the hybrid system operat-

ing in an area with snow build-up, or

where it is snowing. If snowbanks build

up around the vehicle while the hybrid

system is operating, exhaust gases

may collect and enter the vehicle.

■

Exhaust pipe

The exhaust system needs to be checked

periodically. If there is a hole or crack

caused by corrosion, damage to a joint

or abnormal exhaust noise, be sure to

have the vehicle inspected and repaired

by your Lexus dealer.

Riding with children

Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.



It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.



Use the rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
(



P.123, 171)



Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, back door,
seats etc.

WARNING

■

When children are in the vehicle

Never leave children unattended in the

vehicle, and never allow children to have

or use the key.

Children may be able to start the vehicle

or shift the vehicle into neutral. There is

also a danger that children may injure

themselves by playing with the windows,

the moon roof or panoramic moon roof,

or other features of the vehicle. In addi-

tion, heat build-up or extremely cold

temperatures inside the vehicle can be

fatal to children.

Child restraint systems

Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, etc., written in this manual.

Use a child restraint system when
riding with a small child that cannot
properly use a seat belt. For the
child’s safety, install the child restraint
system to a rear seat. Be sure to fol-
low the installation method that is in
the operation manual enclosed with
the restraint system.

Table of contents

1-2. Child safety

Puerto Rico): P.65

The laws of all 50 states of the U.S.A.
as well as Canada now require the use
of child restraint systems.



Prioritize and observe the warn-
ings, as well as the laws and regula-
tions for child restraint systems.



Use a child restraint system until the
child becomes large enough to
properly wear the vehicle’s seat belt.



Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.

Points to remember

WARNING

■

When a child is riding

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

For effective protection in automobile

accidents and sudden stops, a child

must be properly restrained, using a

seat belt or child restraint system

which is correctly installed. For installa-

tion details, refer to the operation man-

ual enclosed with the child restraint

system. General installation instruction

is provided in this manual.

●

Lexus strongly urges the use of a

proper child restraint system that con-

forms to the weight and size of the

child, installed on the rear seat.

According to accident statistics, the

child is safer when properly restrained

in the rear seat than in the front seat.

●

Holding a child in your or someone

else’s arms is not a substitute for a child

restraint system. In an accident, the

child can be crushed against the wind-

shield or between the holder and the

interior of the vehicle.

■

Handling the child restraint system

If the child restraint system is not prop-

erly fixed in place, the child or other pas-

sengers may be seriously injured or even

killed in the event of sudden braking, sud-

den swerving, or an accident.

●

If the vehicle were to receive a strong

impact from an accident, etc., it is pos-

sible that the child restraint system has

damage that is not readily visible. In

such cases, do not reuse the restraint

system.

●

Except for Puerto Rico: Make sure you

have complied with all installation

instructions provided with the child

restraint system manufacturer and that

the system is properly secured.

●

For Puerto Rico: Depending on the

child restraint system, installation may

be difficult or impossible. In those

cases, check whether the child

restraint system is suitable for install-

ment in the vehicle. (



P.47) Be sure to

install and observe the usage rules

after carefully reading the child

restraint system fixing method in this

manual, as well as the operation man-

ual enclosed with the child restraint

system.

●

Keep the child restraint system prop-

erly secured on the seat even if it is not

in use. Do not store the child restraint

system unsecured in the passenger

compartment.

●

If it is necessary to detach the child

restraint system, remove it from the

vehicle or store it securely in the lug-

gage compartment.

Recommended child restraint systems and Compatibility table

The child restraint systems mentioned in the table may not be available outside the
LATIN America and the Caribbean countries.
When securing some types of child
restraint systems in rear seat, it may not
be possible to properly use the seat
belts in positions next to the child
restraint without interfering with it or
affecting seat belt effectiveness. Be
sure your seat belt fits snugly across
your shoulder and low on your hips. If it
does not, or if it interferes with the child
restraint, move to a different position.
Failure to do so may result in death or
serious injury.



When installing a child restraint in
the rear seats, adjust the front seat
so that it does not interfere with the
child or child restraint system.



When installing a child seat with
support base, if the child seat inter-
feres with the seatback when latch-
ing it into the support base, adjust
the seatback rearward until there is
no interference.



If the seat belt shoulder anchor is
ahead of the child seat belt guide,
move the seat cushion forward.

■

When using a child restraint system

Observe the following precautions.

Failure to do so may result in death or

serious injury.

1-2. Child safety

For
safety

and
security

WARNING

●

Never install a rear-facing child

restraint system on the front passenger

seat even if the “AIR BAG OFF” indi-

cator light is illuminated. In the event of

an accident, the force of the rapid infla-

tion of the front passenger airbag can

cause death or serious injury to the

child if the rear-facing child restraint

system is installed on the front passen-

ger seat.

●

A forward-facing child restraint system

may be installed on the front passen-

ger seat only when it is unavoidable. A

child restraint system that requires a

top tether strap should not be used in

the front passenger seat since there is

no top tether strap anchor for the front

passenger seat.

●

A forward-facing child restraint system

may be installed on the front passen-

ger seat only when it is unavoidable.

When installing a forward-facing child

restraint system on the front passenger

seat, raise the seatback as much as

possible, move the seat to the rear-

most position, and raise the seat to the

highest position, even if the “AIR BAG

OFF” indicator light is illuminated.

If the head restraint interferes with the
installation of the child restraint system,
and the head restraint can be removed,
remove the head restraint.
If the head restraint cannot be removed,
raise it to the uppermost position.

●

Do not allow the child to lean his/her

head or any part of his/her body

against the door or the area of the seat,

front or rear pillars, or roof side rails

from which the SRS side airbags or

SRS curtain shield airbags deploy even

if the child is seated in the child

restraint system. It is dangerous if the

SRS side airbags and curtain shield air-

bags inflate, and the impact could

cause death or serious injury to the

child.

●

When a booster seat is installed,

always ensure that the shoulder belt is

positioned across the center of the

child’s shoulder. The belt should be

kept away from the child’s neck, but

not so that it could fall off the child’s

shoulder.

●

Use child restraint system suitable to

the age and size of the child and install

it to the rear seat.

●

If the driver’s seat interferes with the

child restraint system and prevents it

from being attached correctly, attach

the child restraint system to the

right-hand rear seat.

●

Adjust the front passenger seat so that

it does not interfere with the child

restraint system.
