If the head restraint cannot be removed,

WARNING

●

When securing some types of child

restraint systems in rear seats, 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 posi-

tion. Failure to do so may result in

death or serious injury.

●

When installing a child restraint system

in the rear center seat, adjust both seat

cushions to the same position and

align both seatbacks at the same

angle. The seatbacks must be adjusted

to the same angle. Otherwise, the

child restraint system cannot be

securely restrained and this may cause

death or serious injuries in the event of

sudden braking, sudden swerving or

an accident.

●

If the seat is adjusted, reconfirm the

security of the child restraint system.

■

When installing a booster seat

To prevent the belt from going into ALR

lock mode, do not fully extend the shoul-

der belt. ALR mode causes the belt to

tighten only. This could cause injury or

discomfort to the child. (



P.30)

■

Do not use a seat belt extender

If a seat belt extender is used when

installing a child restraint system, the seat

belt will not securely hold the child

restraint system, which could cause

death or serious injury to the child or

other passengers in the event of sudden

braking, sudden swerving or an accident.

WARNING

■

When installing a child restraint sys-

tem

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

When using the LATCH anchors, be

sure that there are no foreign objects

around the anchors and that the seat

belt is not caught behind the child

restraint system.

●

Follow all installation instructions pro-

vided by the child restraint system

manufacturer.

●

Never attach two child restraint system

attachments to the same anchor. In a

collision, one anchor may not be

strong enough to hold two child

restraint system attachments and may

break.

If the LATCH anchors are already in

use, use the seat belt to install a child

restraint system in the center seat.

●

When securing some types of child

restraint systems in rear seats, it may

not be possible to properly use the

Important! Read this information about
exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also
sends out radio frequency (RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.

Those standards were based on com-

the relevant scientific literature. Over
120 scientists, engineers, and physi-
cians from universities, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.

■

Conditions in which the gasoline engine

may not stop

The gasoline engine starts and stops auto-

matically. However, it may not stop auto-

matically in the following conditions:

●

During gasoline engine warm-up

●

During hybrid battery (traction battery)

charging

●

When the temperature of the hybrid bat-

tery (traction battery) is high or low

●

When the heater is switched on

●

When the hood is opened during

Depending on the circumstances, the gaso-

line engine may also not stop automatically

in other situations.

■

Charging the hybrid battery (traction

battery)

As the gasoline engine charges the hybrid

battery (traction battery), the battery does

not need to be charged from an outside

source. However, if the vehicle is left parked

for a long time the hybrid battery (traction

battery) will slowly discharge. For this rea-

son, be sure to drive the vehicle at least

once every few months for at least 30 min-

utes or 10 miles (16 km). If the hybrid bat-

tery (traction battery) becomes fully

discharged and you are unable to start the

hybrid system, contact your Lexus dealer.

■

Charging the 12-volt battery



P.558

■

After the 12-volt battery has discharged

or when the terminal has been removed

and installed during exchange, etc.

The gasoline engine may not stop even if

the vehicle is being driven by the hybrid bat-

tery (traction battery). If this continues for a

few days, contact your Lexus dealer.

■

Sounds and vibrations specific to a

hybrid electric vehicle

Because there is no engine sound or vibra-

tion, it is easy to mistake the hybrid electric

vehicle for being off when it is actually still

running, as indicated by the “READY” indi-

cator being illuminated. For safety, make

sure to always shift the shift position to P

and apply the parking brake when parked.
The following sounds or vibrations may

occur when the hybrid system is operating

and are not a malfunction:

●

Motor sounds may be heard from the

engine compartment.

●

Sounds may be heard from the hybrid

battery (traction battery) behind the rear

seats when the hybrid system starts or

stops.

●

Relay operating sounds such as a snap or

soft clank will be emitted from the hybrid

battery (traction battery), under the rear

seats, when the hybrid system is started

or stopped.

●

Sounds from the hybrid system may be

heard when the back door is open.

●

Sounds may be heard from the transmis-

sion when the gasoline engine starts or

stops, when driving at low speeds, or

■

When “Acoustic Vehicle Alerting Sys-

tem Malfunction Visit your Dealer” is

displayed on the multi-information dis-

play

The Acoustic Vehicle Alerting System may

be malfunctioning. Have the vehicle

inspected by your Lexus dealer immedi-

ately.

: This function can only be used in the

mainland U.S.A. It cannot be used in
other states and territories, including
Alaska and Hawaii.

This system operates based on the
driving situation and traffic information
to enhance fuel economy.
For details about Predictive efficient
drive, refer to the “MULTIMEDIA
OWNER’S MANUAL”.

■

Predictive deceleration support



When the vehicle approaches to
predictive deceleration support
points registered in the navigation
system, the engine braking force will
be increased according to the driv-
ing conditions to more efficiently
charge the hybrid battery (traction
battery) after the accelerator pedal
is released.

Running out of fuel

When the vehicle has run out of fuel and the

hybrid system cannot be started, refuel the

vehicle with at least enough gasoline to

make the low fuel level warning light

(



P.519) go off. If there is only a small

amount of fuel, the hybrid system may not

be able to start. (The standard amount of

fuel is about 2.6 gal. [9.8 L, 2.2 Imp. gal.],

when the vehicle is on a level surface. This

value may vary when the vehicle is on a

slope. Add extra fuel when the vehicle is

inclined.)

■

Electromagnetic waves

●

High voltage parts and cables on hybrid

electric vehicles incorporate electro-

magnetic shielding, and therefore emit

approximately the same amount of elec-

tromagnetic waves as conventional gaso-

line powered vehicles or home electronic

appliances.

●

Your vehicle may cause sound interfer-

ence in some third party-produced radio

parts.

WARNING

■

High voltage precautions

This vehicle has high voltage DC and AC

systems as well as a 12-volt system. DC

and AC high voltage is very dangerous

and can cause severe burns and electric

shock that may result in death or serious

injury.

●

Never touch, disassemble, remove or

replace the high voltage parts, cables

or their connectors.

●

The hybrid system will become hot

after starting as the system uses high

voltage. Be careful of both the high

voltage and the high temperature, and

always obey the warning labels

attached to the vehicle.

●

Never try to open the service plug

access hole located under the rear

seat. The service plug is used only

when the vehicle is serviced and is

subject to high voltage.

■

Road accident cautions

Observe the following precautions to

reduce the risk of death or serious injury:

●

Stop the vehicle in a safe place to pre-

vent subsequent accidents. While

depressing the brake pedal, apply the

parking brake and shift the shift posi-

tion to P to stop the hybrid system.

Then, slowly release the brake pedal.

●

Do not touch the high voltage parts,

cables and connectors.

●

If electric wires are exposed inside or

outside your vehicle, an electric shock

may occur. Never touch exposed elec-

tric wires.

●

If a fluid leak occurs, do not touch the

fluid as it may be strong alkaline elec-

trolyte from the hybrid battery (trac-

tion battery). If it comes into contact

with your skin or eyes, wash it off

immediately with a large amount of

water or, if possible, boric acid solu-

tion. Seek immediate medical atten-

tion.

●

If a fire occurs in the hybrid electric

vehicle, leave the vehicle as soon as

possible. Never use a fire extinguisher

that is not meant for electric fires.

Using even a small amount of water

may be dangerous.

●

If your vehicle needs to be towed, do

so with all four wheels raised. If the

wheels connected to the electric

motor (traction motor) are on the

ground when towing, the motor may

continue to generate electricity. This

may cause a fire. (

P.513)

●

Carefully inspect the ground under the

vehicle. If you find that liquid has

leaked onto the ground, the fuel sys-

tem may have been damaged. Leave

the vehicle as soon as possible.

■

Hybrid battery (traction battery)

●

Never resell, hand over or modify the

hybrid battery. To prevent accidents,

hybrid batteries that have been

removed from a disposed vehicle are

collected through your Lexus dealer.

Do not dispose of the battery yourself.

Unless the battery is properly col-

lected, the following may occur, result-

ing in death or serious injury:

• The hybrid battery may be illegally dis-

posed of or dumped, and it is hazard-

ous to the environment or someone

may touch a high voltage part, result-

ing in an electric shock.

1-4. Hybrid system

The air intake vents for the hybrid bat-
tery (traction battery) are located
under the rear seats.
If the air intake vents are blocked, it

could lead to a reduction in hybrid bat-
tery (traction battery) output.

If input/output of the hybrid battery (trac-
tion battery) becomes limited and the dis-
tance that the vehicle can be driven using
the electric motor (traction motor) is
reduced, the fuel economy may ber-
educed.

When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-

WARNING

• The hybrid battery is intended to be

used exclusively with your hybrid vehi-

cle. If the hybrid battery is used outside

of your vehicle or modified in any way,

accidents such as electric shock, heat

generation, smoke generation, an

explosion and electrolyte leakage may

occur.

When reselling or handing over your

vehicle, the possibility of an accident is

extremely high because the person

receiving the vehicle may not be aware

of these dangers.

●

If your vehicle is disposed of without

the hybrid battery having been

removed, there is a danger of serious

electric shock if high voltage parts,

cables and their connectors are

touched. In the event that your vehicle

must be disposed of, the hybrid battery

must be disposed of by your Lexus

dealer or a qualified service shop. If

the hybrid battery is not disposed of

properly, it may cause electric shock

that can result in death or serious

injury.

NOTICE

■

Hybrid battery (traction battery) air

Do not carry large amounts of water

such as water cooler bottles in the vehi-

cle. If water spills onto the hybrid battery

(traction battery), the battery may be

damaged. Have the vehicle inspected by

your Lexus dealer.
