■

SRS airbag precautions

Observe the following precautions

regarding the SRS airbags.

Failure to do so may cause death or seri-

ous injury.

●

The driver and all passengers in the

vehicle must wear their seat belts

properly.

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 air-

bag is the first 2 - 3 in. (50 - 75 mm) of

inflation, 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 breast-

bone. If you sit less than 10 in. (250

mm) away now, you can change your

driving position in several ways:

• Move your seat to the rear as far as

you can while still reaching the pedals

comfortably.

• Slightly recline the back of the seat.

Although vehicle designs vary, many

drivers can achieve the 10 in. (250

mm) distance, even with the driver

seat all the way forward, simply by

reclining the back of the seat some-

what. If reclining the back of your seat

makes it hard to see the road, raise

yourself by using a firm, non-slippery

cushion, or raise the seat if your vehi-

cle 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 recom-

mended by NHTSA above, while still

maintaining control of the foot pedals,

steering wheel, and your view of the

instrument panel controls.

1-1. For safe use

WARNING

●

If the seat belt extender has been con-

nected to the driver’s seat belt buckle

but the seat belt extender has not also

been fastened to the latch plate of the

driver’s seat belt, the SRS front airbags

for the driver will judge that the driver

is wearing the seat belt even though

the seat belt has not been connected.

In this case, the SRS front airbags for

the driver may not activate correctly in

a collision, resulting in death or serious

injury in the event of a collision. Be

sure to wear the seat belt with the seat

belt extender.

●

The SRS front passenger airbag also

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 as far from the air-

bag as possible with the seatback

adjusted, so the front passenger sits

upright.

●

Improperly seated and/or restrained

infants and children can be killed or

seriously injured by a deploying air-

bag. 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.43)

●

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 unit or

sit on the knees of a front passenger.

●

Do not allow the front seat occupants

to hold items on their knees.

●

Do not lean against the door, the roof

side rail or the front, side and rear pil-

lars.

●

Do not allow anyone to kneel on the

passenger seats toward the door or

put their head or hands outside the

vehicle.

1-1. For safe use

For safety and security

WARNING

●

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.

These items can become projectiles

when the SRS driver, front passenger

and knee airbags deploy.

●

Do not attach anything to areas such

as a door, windshield, side window,

front or rear pillar, roof side rail and

assist grip.

●

Do not hang coat hangers or other

hard objects on the coat hooks. All of

these items could become projectiles

and may cause death or serious injury,

should the SRS curtain shield airbags

deploy.

●

If a vinyl cover is put on the area where

the SRS knee airbag will deploy, be

sure to remove it.

●

Do not use seat accessories which

cover the parts where the SRS side air-

bags inflate as they may interfere with

inflation of the SRS airbags. Such

accessories may prevent the side air-

bags from activating correctly, disable

the system or cause the side airbags to

inflate accidentally, resulting in death

or serious injury.

●

Do not strike or apply significant levels

of force to the area of the SRS airbag

components or the front doors.

Doing so can cause the SRS airbags to

malfunction.

●

Do not touch any of the component

parts immediately after the SRS air-

bags 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.

●

If the areas where the SRS airbags are

stored, such as the steering wheel pad

and front and rear pillar garnishes, are

damaged or cracked, have them

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 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 (inflate) accidentally, causing

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.

1-1. For safe use

WARNING

●

Make sure the “PASSENGER AIR

BAG OFF” indicator light is not illumi-

nated when using the seat belt

extender for the front passenger seat.

If the “PASSENGER 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 “PAS-

SENGER AIR BAG ON” indicator

light is illuminated. If you use the seat

belt extender while the “PASSENGER

AIR BAG OFF” indicator light is illu-

minated, 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

on the front passenger seat seatback

from the rear passenger seat.

●

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 “PASSEN-

GER 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 “PASSENGER AIR BAG

ON” indicator light is illuminated. If the

“PASSENGER AIR BAG OFF” indi-

cator is illuminated, ask the passenger

to sit up straight, well back in the seat,

feet on the floor, and with the seat belt

worn correctly. If the “PASSENGER

AIR BAG OFF” indicator still remains

illuminated, either ask the passenger

to move to the rear seat, or if that is not

possible, move the front passenger

seat fully rearward.

●

When it is unavoidable to install a for-

ward-facing child restraint system on

the front passenger seat, install the

child restraint system on the front pas-

senger seat in the proper order.

(



P.45)

●

Do not modify or remove the front

seats.

●

Do not kick the front passenger seat or

subject it to severe impact. Otherwise,

the SRS warning light may come on to

indicate a malfunction of the front pas-

senger occupant classification system.

In this case, contact your Lexus dealer

immediately.

●

Child restraint systems installed on the

rear seat should not contact the front

seatbacks.

●

Do not use a seat accessory, such as a

cushion and seat cover, that covers the

seat cushion surface.

●

Do not modify or replace the uphol-

stery of the front seat.

●

Do not place anything between the

console box and front passenger seat.

Otherwise, the system may not detect

the front passenger properly, leading

to improper operation of the airbags.

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 trunk lid closed.

●

If you smell exhaust gases in the vehi-

cle even when the trunk lid 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 operating 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 oper-

ating 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

P.107, 132)



Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, 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 other features of the

vehicle. In addition, 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 follow the installation method
that is in the operation manual
enclosed with the restraint system.

Table of contents

Points to remember

1-2. Child safety

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.

■

Types of child restraint system installation methods

Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.

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 instal-

lation details, refer to the operation

manual 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,

sudden 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.

●

Make sure you have complied with all

installation instructions provided with

the child restraint system manufac-

turer and that the system is properly

secured.

●

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 trunk.

WARNING

■

When using a child restraint system

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

Never install a rear-facing child

restraint system on the front passen-

ger seat even if the “PASSENGER

AIR BAG OFF” indicator light is illu-

minated. In the event of an accident,

the force of the rapid inflation 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 passenger seat.

●

A forward-facing child restraint sys-

tem may be installed on the front pas-

senger 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 sys-

tem may be installed on the front pas-

senger seat only when it is

unavoidable. When installing a for-

ward-facing child restraint system on

the front passenger seat, adjust the

seatback angle to the most upright

position, move the seat to the rearmost

position, and raise the seat to the

upper most position, even if the “PAS-

SENGER AIR BAG OFF” indicator

light is illuminated.

●

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 and curtain shield airbags

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.

1-2. Child safety

For safety and security

A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt.

■

Child restraint LATCH anchors

LATCH anchors are provided for the
outboard rear seat. (Marks displaying
the location of the anchors are
attached to the seats.)

WARNING

■

When installing a child restraint sys-

tem

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

Do not allow children to play with the

seat belt. If the seat belt becomes

twisted around a child’s neck, it may

lead to choking or other serious inju-

ries that could result in death.

If this occurs and the buckle cannot be

unfastened, scissors should be used to

cut the belt.

●

Ensure that the belt and plate are

securely locked and the seat belt is not

twisted.

●

Shake the child restraint system left

and right, and forward and backward

to ensure that it has been securely

installed.

●

After securing a child restraint system,

never adjust the seat.

●

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.

●

Follow all installation instructions pro-

vided by the child restraint system

manufacturer.

●

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

position. Failure to do so may result in

death or serious injury.

■

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.26)

■

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.

Gasoline engine

Electric motor (traction motor)

■

When stopped/during start off

The gasoline engine stops

when the

vehicle is stopped. During start off, the
electric motor (traction motor) drives
the vehicle. At slow speeds or when
traveling down a gentle slope, the
engine is stopped

and the electric

motor (traction motor) is used.
When the shift lever is in N, the hybrid
battery (traction battery) is not being

charged.

: When the hybrid battery (traction bat-

tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop.

■

During normal driving

The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.

Hybrid system features

Your vehicle is a Hybrid Electric Vehicle. It has characteristics different from
conventional vehicles. Be sure you are closely familiar with the characteristics
of your vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric
motor (traction motor) according to driving conditions, improving fuel effi-
ciency and reducing exhaust emissions.

System components

1-4. Hybrid system

■

When accelerating sharply

When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine via
the electric motor (traction motor).

■

When braking (regenerative brak-
ing)

The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged.

■

Regenerative braking

In the following situations, kinetic energy is

converted to electric energy and decelera-

tion force can be obtained in conjunction

with the recharging of the hybrid battery

(traction battery).

●

The accelerator pedal is released while

driving with the shift lever in D or S.

●

The brake pedal is depressed while driv-

ing with the shift lever in D or S.

■

EV indicator

The EV indicator comes on when the vehi-

cle is driven using only the electric motor

(traction motor) or the gasoline engine is

stopped.

■

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

: Depending on the circumstances, the

gasoline engine may also not stop auto-
matically 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 reason, be sure to drive the vehicle at

least once every few months for at least 30

minutes or 10 miles (16 km). If the hybrid

battery (traction battery) becomes fully dis-

charged and you are unable to start the

hybrid system, contact your Lexus dealer.

■

Charging the 12-volt battery



P.389

■

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

battery (traction battery). If this continues

for a few days, contact your Lexus dealer.

in accordance with driving style and driving

conditions.

■

Starting the hybrid system in an

extremely cold environment (for vehi-

cles sold in except Canada)

When the hybrid battery (traction battery)

is extremely cold (below approximately -

22°F [-30°C]) under the influence of the

outside temperature, it may not be possible

to start the hybrid system. In this case, try to

start the hybrid system again after the tem-

perature of the hybrid battery increases

due to the outside temperature increase

etc.

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 (right side). 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:

●

Pull your vehicle off the road, apply the

parking brake, shift the shift lever to P,

and turn the hybrid system off.

●

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

electric wires.

●

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 front 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.357)

●

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.

1-4. Hybrid system

There is an air intake vent under the
rear seat (right side) for the purpose of

WARNING

●

For vehicles sold in Canada: If a fluid

leak occurs, do not touch the fluid as it

may be strong alkaline electrolyte

from the hybrid battery (traction bat-

tery). If it comes into contact with your

skin or eyes, wash it off immediately

with a large amount of water or, if pos-

sible, boric acid solution. Seek imme-

diate medical attention.

●

For vehicles sold in except Canada:

Do not touch the battery if liquid is

leaking from or adhering to it. If elec-

trolyte (carbonic-based organic elec-

trolyte) from the hybrid battery

(traction battery) comes into contact

with the eyes or skin, it could cause

blindness or skin wounds. In the

unlikely event that it comes into con-

tact with the eyes or skin, wash it off

immediately with a large amount of

water, and seek immediate medical

attention.

●

For vehicles sold in except Canada: If

electrolyte is leaking from the hybrid

battery (traction battery), do not

approach the vehicle.

Even in the unlikely event that the

hybrid battery (traction battery) is

damaged, the internal construction of

the battery will prevent a large amount

of electrolyte from leaking out. How-

ever, any electrolyte that does leak out

will give off a vapor. This vapor is an

irritant to skin and eyes and could

cause acute poisoning if inhaled.

●

For vehicles sold in except Canada:

Do not bring burning or high-tem-

perature items close to the electrolyte.

The electrolyte may ignite and cause a

fire.

■

Hybrid battery (traction battery)

●

For vehicles sold in except Canada:

Your vehicle contains a sealed lithium-

ion 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 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.

• The hybrid battery is intended to be

used exclusively with your Hybrid

Electric Vehicle. If the hybrid battery is

used outside of your vehicle or modi-

fied in any way, accidents such as elec-

tric shock, heat generation, smoke

generation, an explosion and electro-

lyte 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 prop-

erly, it may cause electric shock that

can result in death or serious injury.
