1-1. For safe use

LS500_OM_(U)_1809

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.

●

Do not leave the vehicle with the

engine 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 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 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.

The laws of all 50 states of the U.S.A.
as well as Canada now require the use
of child restraint systems.
 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 rear door child-protector

lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
(

P.103, 144)

 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 panoramic moon roof,

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.

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 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 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.

1-2. Child safety

LS500_OM_(U)_1809

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
using a seat belt (child restraint
lock function belt)

Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.

WARNING

●

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 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 “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.

●

If the driver’s seat interferes with the

child restraint system and prevents it

from being attached correctly, attach

the child restraint system to the

right-hand rear seat.

●

Adjust the front passenger seat so that

it does not interfere with the child

restraint system.

WARNING

●

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 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. 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.

■

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.
