LEXUS GS 300, GS 350 (2019 year). Manual - part 4

WARNING

■

Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classifica-

tion 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” indicator light is not illuminated when using the seat

belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-

minated, disconnect 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 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

pockets).

●

Do not put weight on the front passenger 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 passenger 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 effec-

tiveness of the seat belt system.

●

If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illumi-

nated. 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 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 forward-facing child restraint system on the front

passenger seat, install the child restraint system on the front passenger seat in the

proper order. (

P. 63)

●

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 passenger

occupant classification system. In this case, contact your Lexus dealer immediately.

WARNING

■

Front passenger occupant classification system precautions

●

Child restraint systems installed on the rear seat should not contact the front seat-

backs.

●

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 upholstery of the front seat.

●

Adjust the front passenger seat so that the head restraint does not touch the ceiling. If

the head restraint is left in contact with the ceiling, the system may not detect the front

passenger properly, leading to improper operation of the airbags.

1-1. For safe use

Safety information for children

●

It is recommended that children sit in the rear seats to avoid accidental con-
tact 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 acci-
dentally. (

P. 146, 181)

●

Do not let small children operate equipment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.

Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.

WARNING

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 tempera-

tures inside the vehicle can be fatal to children.

1-1. For safe use

For safety

and security

Child restraint systems

Studies have shown that installing a child restraint on a rear seat is much safer
than installing one on the front passenger seat.

●

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

●

For installation details, follow the instructions provided with the child restraint
system.
General installation instructions are provided in this manual. (

P. 63)

A child restraint system for a small child or baby must itself be properly
restrained on the seat with the LATCH anchors or the lap portion of the lap/
shoulder belt.
The laws of all 50 states of the U.S.A. and Canada now require the use of child
restraint systems.

Points to remember

1-1. For safe use

Child restraint systems are classified into the following 3 types according to the
age and size of the child:

■

Selecting an appropriate child restraint system

●

Use a child restraint system appropriate for the child until the child becomes large

enough to properly wear the vehicle’s seat belt.

●

If the child is too large for a child restraint system, sit the child on a rear seat and use the

vehicle’s seat belt. (

P. 36)

WARNING

■

Child restraint precautions

●

For effective protection in automobile accidents and sudden stops, a child must be

properly restrained, using a seat belt or child restraint system depending on the age

and size of the child. Holding a child in your arms is not a substitute for a child restraint

system. In an accident, the child can be crushed against the windshield, or between

you and the vehicle’s interior.

●

Lexus strongly urges the use of a proper child restraint system that conforms to the

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.

●

Never install a rear-facing child restraint system on the front passenger seat even if

the “AIR BAG OFF” indicator light is illuminated.

In the event of an accident, the force of the rapid inflation of the front passenger air-

bag can cause death or serious injury to the child if the rear-facing child restraint sys-

tem is installed on the front passenger seat.

●

A forward-facing child restraint system may be installed on the front passenger 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. Adjust the seatback as upright as possible and

always move the seat as far back as possible even if the “AIR BAG OFF” indicator

light is illuminated, because the front passenger airbag could inflate with considerable

speed and force. Otherwise, the child may be killed or seriously injured.

●

Do not use the seat belt extender when installing a child restraint system on the front

or rear passenger seat. If installing a child restraint system with the seat belt extender

connected to the seat belt, the seat belt will not securely hold the child restraint sys-

tem, which could cause death or serious injury to the child or other passengers in the

event of a sudden stop, sudden swerve or accident.

●

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 and 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 airbags

inflate, and the impact could cause death or serious injury to the child.

●

Make sure you have complied with all installation instructions provided by the child

restraint manufacturer and that the system is properly secured. If it is not secured

properly, it may cause death or serious injury to the child in the event of a sudden

stop, sudden swerve or accident.

1-1. For safe use

WARNING

■

When children are in the vehicle
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 injuries that could result in death.

If this occurs and the buckle cannot be unfastened, scissors should be used to cut the

belt.

■

When the child restraint system is not in use

●

Keep the child restraint system properly 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. If a head restraint was removed when installing a child

restraint system, always install the head restraint before driving. This will prevent it

from injuring passengers in the event of a sudden stop, sudden swerve or accident.

WARNING

■

When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder

belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort to

the child. (

P. 37)

■

When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix the

child restraint system securely in place.

If the child restraint system is not correctly fixed in place, the child or other passengers

may be seriously injured or even killed in the event of sudden braking, sudden swerving

or an accident.

●

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.

●

Only put a forward-facing child restraint sys-

tem on the front seat when unavoidable.

When installing a forward-facing child

restraint system on the front passenger seat,

move the seat as far back as possible even if

the “AIR BAG OFF” indicator light is illumi-

nated. Failure to do so may result in death or

serious injury if the airbags deploy (inflate).

1-1. For safe use

WARNING

■

When installing a child restraint system

●

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. Failing to do so may result in

death or serious injury in the event of sudden braking, sudden swerving or an acci-

dent.

●

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.

●

Follow all installation instructions provided by the child restraint system manufacturer.

■

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.

■

To correctly attach a child restraint system to the anchors
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. Make sure

the child restraint system is securely attached, or it may cause death or serious injury to

the child or other passengers in the event of sudden braking, sudden swerving or an

accident.
