There is a malfunction in the system

: 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 him/her as an adult depending on
his/her 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 him/her 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 forward-

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

WARNING

■

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 serious 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” indi-

cator light is not illuminated when

using the seat belt extender for the

front passenger seat. If the “AIR BAG

OFF” indicator light is illuminated, dis-

connect 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 illumi-

nated. If you use the seat belt extender

while the “AIR BAG OFF” indicator

light is illuminated, 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 “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

passenger to sit up straight, well back

in the seat, feet on the floor, and with

the seat belt worn correctly. If the “AIR

BAG OFF” indicator still remains illu-

minated, 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.49)

●

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.

1-1. For safe use

For safety and security

WARNING

●

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.

Exhaust gas precautions

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

WARNING

Exhaust gases contain 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.

■

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.

1-1. For safe use

WARNING

■

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

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 (if equipped) or other fea-

tures 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 fol-
low the installation method that is in
the operation manual enclosed with
the restraint system.

Table of contents

Points to remember

1-2. Child safety

tions for child restraint systems.



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



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

■

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. Fail-

ure to do so may result in death or seri-

ous 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.

●

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 lug-

gage compartment.

WARNING

■

When using a child restraint system

Observe the following precautions. Fail-

ure to do so may result in death or seri-

ous injury.

●

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, move the seat as far back as pos-

sible, and raise the seat to the upper

most position, even if the “AIR BAG

OFF” indicator light is illuminated. If

the head restraint interferes with the

child restraint system installation and

the head restraint can be removed,

remove the head restraint.

●

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.

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.

■

Installing child restraint system

WARNING

■

When installing a child restraint sys-

tem

Observe the following precautions. Fail-

ure to do so may result in death or seri-

ous 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.

For owners in Canada:

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

seatbacks at the same angle. Other-

wise, 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.

■

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.28)

■

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.
