visibility will be reduced, the windows

may become fogged-up, and the road

will be slippery.

●

Drive carefully when it starts to rain,

because the road surface will be espe-

cially slippery.

●

Refrain from high speeds when driving on

an expressway in the rain, because there

may be a layer of water between the tires

and the road surface, preventing the

steering and brakes from operating prop-

erly.

■

Driving condition

Idling time

Normal city driving or

high-speed driving (at the

highway speed limit or rec-

ommended speed)

Not neces-

sary

Steep hill driving or continu-

ous driving (race track driving

etc.)

mately 1

minute

WARNING

Observe the following precautions. Fail-

ure to do so may result in death or seri-

ous injury.

■

When starting the vehicle

Always keep your foot on the brake

pedal while stopped with the engine run-

ning. This prevents the vehicle from

creeping.

■

When driving the vehicle

●

Do not drive if you are unfamiliar with

the location of the brake and accelera-

tor pedals to avoid depressing the

wrong pedal.

• Accidentally depressing the accelera-

tor pedal instead of the brake pedal

will result in sudden acceleration that

may lead to an accident.

• When backing up, you may twist your

body around, leading to a difficulty in

operating the pedals. Make sure to

operate the pedals properly.

• Make sure to keep a correct driving

posture even when moving the vehicle

only slightly. This allows you to depress

the brake and accelerator pedals

properly.

• Depress the brake pedal using your

right foot. Depressing the brake pedal

using your left foot may delay

response in an emergency, resulting in

an accident.

●

Do not drive the vehicle over or stop

the vehicle near flammable materials.

The exhaust system and exhaust gases

can be extremely hot. These hot parts

may cause a fire if there is any flamma-

ble material nearby.

●

During normal driving, do not turn off

the engine. Turning the engine off

while driving will not cause loss of

steering or braking control, but the

power assist to these systems will be

lost. This will make it more difficult to

steer and brake, so you should pull

over and stop the vehicle as soon as it

is safe to do so.

However, in the event of an emer-

gency, such as if it becomes impossible

to stop the vehicle in the normal way:



P.318

122

4-1. Before driving

WARNING

●

Use engine braking (downshift) to

maintain a safe speed when driving

down a steep hill.

Using the brakes continuously may

cause the brakes to overheat and lose

effectiveness. (



P.133)

●

Do not adjust the positions of the

steering wheel, the seat, or the inside

or outside rear view mirrors while driv-

ing.

Doing so may result in a loss of vehicle

control.

●

Always check that all passengers’

arms, heads or other parts of their

body are not outside the vehicle.

●

Do not drive across a river or through

other bodies of water.

This may cause electric/electronic

components to short circuit, damage

the engine or cause other serious

damage to the vehicle.

●

Do not drive in excess of the speed

limit. Even if the legal speed limit per-

mits it, do not drive over 85 mph (140

km/h) unless your vehicle has

high-speed capability tires. Driving

over 85 mph (140 km/h) may result in

tire failure, loss of control and possible

injury. Be sure to consult a tire dealer

to determine whether the tires on your

vehicle are high-speed capability tires

or not before driving at such speeds.

■

When driving on slippery road sur-

faces

●

Sudden braking, acceleration and

steering may cause tire slippage and

reduce your ability to control the vehi-

cle.

●

Sudden acceleration, engine braking

due to shifting, or changes in engine

speed could cause the vehicle to skid.

●

After driving through a puddle, lightly

depress the brake pedal to make sure

that the brakes are functioning prop-

erly. Wet brake pads may prevent the

brakes from functioning properly. If the

brakes on only one side are wet and

not functioning properly, steering con-

trol may be affected.

■

When shifting the shift lever

●

Do not let the vehicle roll backward

while the shift lever is in a driving posi-

tion, or roll forward while the shift lever

is in R.

Doing so may cause the engine to stall

or lead to poor brake and steering

performance, resulting in an accident

or damage to the vehicle.

●

Do not shift the shift lever to P while

the vehicle is moving.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

Do not shift the shift lever to R while

the vehicle is moving forward.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

Do not shift the shift lever to a driving

position while the vehicle is moving

backward.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

Shifting the shift lever to N while the

vehicle is moving will disengage the

engine from the transmission. Engine

braking is not available when N is

selected.

●

Be careful not to shift the shift lever

with the accelerator pedal depressed.

Shifting the shift lever to a gear other

than P or N may lead to unexpected

rapid acceleration of the vehicle that

may cause an accident and result in

death or serious injury.

123

4-1. Before driving

Driving

WARNING

■

If you hear a squealing or scraping

noise (brake pad wear limit indica-

tors)

Have the brake pads checked and

replaced by your Lexus dealer as soon as

possible.

Rotor damage may result if the pads are

not replaced when needed.

It is dangerous to drive the vehicle when

the wear limits of the brake pads and/or

those of the brake discs are exceeded.

■

When the vehicle is stopped

●

Do not race the engine.

If the shift lever is any position other

than P or N, the vehicle may acceler-

ate suddenly and unexpectedly, caus-

ing an accident.

●

In order to prevent accidents due to

the vehicle rolling away, always keep

depressing the brake pedal while the

engine is running, and apply the park-

ing brake as necessary.

●

If the vehicle is stopped on an incline,

in order to prevent accidents caused

by the vehicle rolling forward or back-

ward, always depress the brake pedal

and securely apply the parking brake

as needed.

●

Avoid revving or racing the engine.

Running the engine at high speed

while the vehicle is stopped may cause

the exhaust system to overheat, which

could result in a fire if combustible

material is nearby.

■

When the vehicle is parked

●

Do not leave glasses, cigarette lighters,

spray cans, or soft drink cans in the

vehicle when it is in the sun.

Doing so may result in the following:

• Gas may leak from a cigarette lighter

or spray can, and may lead to a fire.

• The temperature inside the vehicle

may cause the plastic lenses and plas-

tic material of glasses to deform or

crack.

• Soft drink cans may fracture, causing

the contents to spray over the interior

of the vehicle, and may also cause a

short circuit in the vehicle’s electrical

components.

●

Do not leave cigarette lighters in the

vehicle. If a cigarette lighter is in a

place such as the glove box or on the

floor, it may be lit accidentally when

luggage is loaded or the seat is

adjusted, causing a fire.

●

Do not attach adhesive discs to the

windshield or windows. Do not place

containers such as air fresheners on

the instrument panel or dashboard.

Adhesive discs or containers may act

as lenses, causing a fire in the vehicle.

●

Do not leave a door or window open if

the curved glass is coated with a met-

allized film such as a silver-colored

one. Reflected sunlight may cause the

glass to act as a lens, causing a fire.

●

Always apply the parking brake, shift

the shift lever to P, stop the engine and

lock the vehicle.

Do not leave the vehicle unattended

while the engine is running.

If the vehicle is parked with the shift

lever in P but the parking brake is not

set, the vehicle may start to move, pos-

sibly leading to an accident.

●

Do not touch the exhaust pipes while

the engine is running or immediately

after turning the engine off.

Doing so may cause burns.

124

4-1. Before driving

WARNING

■

When taking a nap in the vehicle

Always turn the engine off. Otherwise, if

you accidentally move the shift lever or

depress the accelerator pedal, this could

cause an accident or fire due to engine

overheating. Additionally, if the vehicle is

parked in a poorly ventilated area,

exhaust gases may collect and enter the

vehicle, leading to death or a serious

health hazard.

■

When braking

●

When the brakes are wet, drive more

cautiously.

Braking distance increases when the

brakes are wet, and this may cause one

side of the vehicle to brake differently

than the other side. Also, the parking

brake may not securely hold the vehi-

cle.

●

If the brake booster device does not

operate, do not follow other vehicles

closely and avoid hills or sharp turns

that require braking.

In this case, braking is still possible, but

the brake pedal should be depressed

more firmly than usual. Also, the brak-

ing distance will increase. Have your

brakes fixed immediately.

●

Do not pump the brake pedal if the

engine stalls.

Each push on the brake pedal uses up

the reserve for the power-assisted

brakes.

●

The brake system consists of 2 individ-

ual hydraulic systems; if one of the sys-

tems fails, the other will still operate. In

this case, the brake pedal should be

depressed more firmly than usual and

the braking distance will increase.

Have your brakes fixed immediately.

■

If the vehicle becomes stuck

Do not spin the wheels excessively when

any of the tires is up in the air, or the vehi-

cle is stuck in sand, mud, etc. This may

damage the driveline components or

propel the vehicle forward or backward,

causing an accident.

NOTICE

■

When driving the vehicle

●

Do not depress the accelerator and

brake pedals at the same time during

driving, as this may restrain the engine

output.

●

Do not use the accelerator pedal or

depress the accelerator and brake

pedals at the same time to hold the

vehicle on a hill.

■

When parking the vehicle

Always set the parking brake and shift

the shift lever to P. Failure to do so may

cause the vehicle to move or the vehicle

may accelerate suddenly if the accelera-

tor pedal is accidentally depressed.

■

Avoiding damage to vehicle parts

●

Do not turn the steering wheel fully in

either direction and hold it there for an

extended period of time.

Doing so may damage the power

steering.

●

When driving over bumps in the road,

drive as slowly as possible to avoid

damaging the wheels, underside of the

vehicle, etc.

●

IS300: Make sure to idle the engine

immediately after high-load driving.

Stop the engine only after the turbo-

charger has cooled down.

Failure to do so may cause damage to

the turbocharger.

4-1. Before driving

Cargo capacity depends on the total
weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) — (Total weight of occupants)
Steps for Determining Correct Load
Limit —
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or XXX
lbs.” on your vehicle’s placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX
kg or XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity.
For example, if the “XXX” amount
equals 1400 lbs. and there will be five
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400

−

750



150) = 650 lbs.)

(5) Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and lug-

gage load capacity calculated in Step
4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
(



P.128)

Lexus does not recommend towing a
trailer with your vehicle. Your vehicle is not
designed for trailer towing.

Cargo capacity
Total load capacity (vehicle capac-
ity weight) (



P.362)

When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage load capacity will be C lb. (kg) as
follows:

lb. (kg) - A

lb. (kg) = C

lb. (kg)

: A =Weight of people

: B =Total load capacity

Cargo and luggage

Take notice of the following infor-
mation about storage precautions,
cargo capacity and load:

Capacity and distribution

127

4-1. Before driving

Driving

: C =Available cargo and luggage load

In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:

C lb. (kg) - D

lb. (kg) = E

lb. (kg)

: D =Additional weight of people

: E =Available cargo and luggage load

As shown in the example above, if the
number of occupants increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.

WARNING

■

Things that must not be carried in the

trunk

The following things may cause a fire if

loaded in the trunk:

●

Receptacles containing gasoline

●

Aerosol cans

■

Storage precautions

Observe the following precautions.

Failure to do so may prevent the pedals

from being depressed properly, may

block the driver’s vision, or may result in

items hitting the driver or passengers,

possibly causing an accident.

●

Stow cargo and luggage in the trunk

whenever possible.

●

To prevent cargo and luggage from

sliding forward during braking, do not

stack anything in the enlarged trunk.

Keep cargo and luggage low, as close

to the floor as possible.

●

When you fold down the rear seats,

long items should not be placed

directly behind the front seats.

●

Never allow anyone to ride in the

enlarged trunk. It is not designed for

passengers. They should ride in their

seats with their seat belts properly fas-

tened.

●

Do not place cargo or luggage in or on

the following locations.

• At the feet of the driver

• On the front passenger or rear seats

(when stacking items)

• On the package tray

• On the instrument panel

• On the dashboard

• In front of the Center Display

●

Secure all items in the occupant com-

partment.

■

Capacity and distribution

●

Do not exceed the maximum axle

weight rating or the total vehicle

weight rating.

●

Even if the total load of occupant’s

weight and the cargo load is less than

the total load capacity, do not apply the

load unevenly. Improper loading may

cause deterioration of steering or

braking control which may cause

death or serious injury.

gency while driving the vehicle, press

and hold the engine switch for more than

2 seconds, or press it briefly 3 times or

more in succession. (



P.318)

However, do not touch the engine switch

while driving except in an emergency.

Turning the engine off while driving will

not cause loss of steering or braking con-

trol, but the power assist to these systems

will be lost. This will make it more difficult

to steer and brake, so you should pull

over and stop the vehicle as soon as it is

safe to do so.

■

When parking

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

to enter the vehicle and may lead to an

accident caused by light-headedness, or

may lead to death or a serious health

hazard.

●

If the vehicle is in a poorly ventilated

area or a closed area, such as a

garage, stop the engine.

●

Do not leave the vehicle with the

engine running 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 engine running in an

area with snow build-up, or where it is

snowing. If snowbanks build up around

the vehicle while the engine is running,

exhaust gases may collect and enter

●

The high beams may be turned off if a

vehicle ahead that is using fog lights with-

out its headlights turned on is detected.

●

House lights, street lights, traffic signals,

and illuminated billboards or signs and

other reflective objects may cause the

high beams to change to the low beams,

or the low beams to remain on.

●

The following factors may affect the

amount of time taken for the high beams

to turn on or off:

• The brightness of the headlights, fog

lights, and tail lights of vehicles ahead

• The movement and direction of vehicles

ahead

• When a vehicle ahead only has opera-

tional lights on one side

• When a vehicle ahead is a two-wheeled

vehicle

• The condition of the road (gradient,

curve, condition of the road surface, etc.)

• The number of passengers and amount of

luggage in the vehicle

●

The high beams may turn on or off unex-

pectedly.

●

Bicycles or similar vehicles may not be

detected.

●

In the following situations the system may

not be able to correctly detect the sur-

rounding brightness level. This may cause

the low beams to remain on or the high

beams to flash or dazzle pedestrians or

vehicles ahead. In such a case, it is neces-

sary to manually switch between the high

and low beams.

equal to that of headlights, tail lights or

fog lights

• When headlights or tail lights of vehicles

ahead are turned off, dirty, changing

color, or not aimed properly

• When the vehicle is hit by water, snow,

dust, etc. from a preceding vehicle

• When driving through an area of inter-

mittently changing brightness and dark-

ness

• When frequently and repeatedly driving

ascending/descending roads, or roads

with rough, bumpy or uneven surfaces

(such as stone-paved roads, gravel roads,

etc.)

• When frequently and repeatedly taking

curves or driving on a winding road
