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 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 “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 or armrest).

●

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 passen-

ger 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 illumi-

nated, 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.46)

●

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.

: 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.

*5

: 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. (

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 engine <hybrid sys-

tem>.

●

Do not leave the vehicle with the 

engine running <hybrid system operat-

ing> 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 

<hybrid system operating> in an area 

with snow build-up, or where it is 

snowing. If snowbanks build up around 

the vehicle while the engine is running 

<hybrid system is operating>, exhaust 

gases may collect and enter the vehi-

cle.

■

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.

Prioritize and observe the warn-
ings, as well as the laws and regula-

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 window lock switch to 
avoid children operating the 
power window accidentally.



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 

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.

For safety and security

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.

■

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 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.

WARNING

■

When installing a child restraint sys-

tem

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 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, adjust the seatback to the most 

upright position, move the seat as far 

back as possible, and raise the seat to 

the highest position, even if the “AIR 

BAG OFF” indicator light is illumi-

nated. 

If the head restraint interferes with the 

installation of the child restraint system, 

and the head restraint can be 

removed, remove the head restraint. 

Otherwise, put the head restraint in 

the upper most 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 and curtain shield airbags 

inflate, and the impact could cause 

death or serious injury to the child.

Removing a child restraint system 
installed with a seat belt

Press the buckle release button and 
fully retract the seat belt.

When releasing the buckle, the child 
restraint system may spring up due to the 
rebound of the seat cushion. Release the

slowly return it to the stowing position.

■

Child restraint LATCH anchors

LATCH anchors are provided for the 
each rear seat. (Buttons 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 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.
