LEXUS GS 300 (2019 year). Instruction - part 3

1-1. For safe use

WARNING

■

Seat belt damage and wear

●

Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed in

the door.

●

Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts. Do

not use a damaged seat belt until it is replaced. Damaged seat belts cannot protect an

occupant from death or serious injury.

●

Ensure that the belt and plate are locked and the belt is not twisted.

If the seat belt does not function correctly, immediately contact your Lexus dealer.

●

Replace the seat assembly, including the belts, if your vehicle has been involved in a

serious accident, even if there is no obvious damage.

●

Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.

Have any necessary repairs carried out by your Lexus dealer. Inappropriate handling

may lead to incorrect operation.

■

Using a seat belt extender

●

Do not wear the seat belt extender if you can fasten the seat belt without the extender.

●

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

belt will not securely hold the child restraint system, increasing the risk of death or

serious injury in the event of an accident.

●

The personalized extender may not be safe on another vehicle, when used by another

person, or at a different seating position other than the one originally intended.

NOTICE

■

When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender, not

on the seat belt.

This helps prevent damage to the vehicle interior and the extender itself.

SRS side and curtain shield airbags

SRS front side airbags
Can help protect the torso of the front seat occupants
SRS rear side airbags
Can help protect the torso of occupants in the rear outer seats
SRS curtain shield airbags

●

Can help protect primarily the head of occupants in the outer seats

●

Can prevent the occupants from being thrown from the vehicle in the
event of vehicle rollover

1-1. For safe use

For safety

and security

Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system components diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.

■

SRS airbag precautions
Observe the following precautions regarding the SRS airbags.

Failure to do so may cause death or serious 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 seri-

ous 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 airbag 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 breastbone. 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 com-

fortably.

• Slightly recline the back of the seat.

Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm) dis-

tance, even with the driver seat all the way forward, simply by reclining the back of

the seat somewhat. 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 vehicle

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 recommended by NHTSA above, while still maintain-

ing control of the foot pedals, steering wheel, and your view of the instrument panel

controls.

WARNING

■

SRS airbag precautions

●

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 passenger seat should be as far from the airbag 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 airbag. An infant or child who is too small to use a seat belt

should be properly secured using a child restraint system. Lexus strongly recom-

mends that all infants and children be placed in the rear seats of the vehicle and prop-

erly restrained. The rear seats are safer for infants and children than the front

passenger seat. (

P. 59)

●

If the seat belt extender has been connected

to the front seat belt buckles but the seat belt

extender has not also been fastened to the

latch plate of the seat belt, the SRS front air-

bags will judge that the driver and front pas-

senger are wearing the seat belt even though

the seat belt has not been connected. In this

case, the SRS front airbags 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.

●

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.

1-1. For safe use

WARNING

■

SRS airbag precautions

●

Do not lean against the door, the roof side rail

or the front, side and rear pillars.

●

Do not allow anyone to kneel on the passen-

ger seat toward the door or put their head or

hands outside the vehicle.

●

Do not attach anything to or lean anything

against areas such as the dashboard, steering

wheel pad, lower portion of the instrument

panel and door of the glove box.

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 glass, side door glass, front

or rear pillar, roof side rail and assist grip.

(Except for the speed limit sticker

P. 493)

1-1. For safe use

For safety

and security

WARNING

■

SRS airbag precautions

●

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 cur-

tain 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 airbags inflate

as they may interfere with inflation of the airbags. Such accessories may prevent the

side airbags 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 compo-

nents.

Doing so can cause the SRS airbags to malfunction.

●

Do not touch any of the component parts immediately after the SRS airbags 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 resi-

due as soon as possible to prevent skin irritation.

●

If the areas where the SRS airbags are stored, such as the steering wheel pad, door of

the glove box and front and rear pillar garnishes are damaged or cracked, have them

replaced by your Lexus dealer.

●

Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will

disperse the passenger’s weight, which prevents the sensor from detecting the pas-

senger’s weight properly. As a result, the SRS front airbags for the front passenger

may not deploy in the event of a collision.

■

Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without

consulting your Lexus dealer. The SRS airbags may malfunction or deploy (inflate)

accidentally, causing death or serious injury.

●

Installation, removal, disassembly and repair of the SRS airbags

●

Repairs, modifications, removal or replacement of the steering wheel, instrument

panel, dashboard, glove box, seats or seat upholstery, front, side and rear pillars or

roof side rails

●

Repairs or modifications of the front fender, front bumper, or side of the occupant

compartment

●

Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows, winches or

roof luggage carrier

●

Modifications to the vehicle’s suspension system

●

Installation of electronic devices such as mobile two-way radios and CD players

●

Modifications to your vehicle for a person with a physical disability

1-1. For safe use

■

If the SRS airbags deploy (inflate)

●

Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the

extremely high speed deployment (inflation) by hot gases.

●

A loud noise and white powder will be emitted.

●

Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the

seats, the glove box, parts of the front and rear pillars, and roof side rails may be hot for

several minutes. The airbag itself may also be hot.

●

The windshield may crack.

●

For Lexus Enform Safety Connect subscribers, if the SRS airbags deploy or in the event

of a severe rear-end collision, the system is designed to send an emergency call to the

response center, notifying them of the vehicle’s location (without needing to push the

“SOS” button) and an agent will attempt to speak with the occupants to ascertain the

level of emergency and assistance required. If the occupants are unable to communi-

cate, the agent automatically treats the call as an emergency and helps to dispatch the

necessary emergency services. (

P. 72)

■

SRS airbag deployment conditions (SRS front airbags)

●

The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-

old level (the level of force corresponding to an approximately 12 - 18 mph [20 -

30 km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move

or deform on impact

• If the vehicle is involved in an underride collision, such as a collision in which the

front of the vehicle “underrides”, or goes under, the bed of a truck

●

Depending on the type of collision, it is possible that only the seat belt pretensioners will

activate.

●

The SRS front airbags for the front passenger will not activate if there is no passenger

sitting in the front passenger seat. However, the SRS front airbags for the front passen-

ger may deploy if luggage is put in the seat, even if the seat is unoccupied. (

P. 52)

■

SRS airbag deployment conditions (SRS side and curtain shield airbags)

●

The SRS side and curtain shield airbags will deploy in the event of an impact that

exceeds the set threshold level (the level of force corresponding to the impact force

produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehicle

cabin from a direction perpendicular to the vehicle orientation at an approximate

speed of 12 - 18 mph [20 - 30 km/h]).

●

The SRS curtain shield airbags will deploy in the event of vehicle rollover.

●

The SRS side and curtain shield airbags may also deploy in the event of a severe frontal

collision.

For safety

and security

■

Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags, SRS side and curtain shield airbags may also deploy if a serious

impact occurs to the underside of your vehicle. Some examples are shown in the illustra-

tion.

The SRS curtain shield airbags may also deploy under the situations shown in the illustra-

tion.

■

Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear

collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a

collision of any type causes sufficient forward deceleration of the vehicle, deployment of

the SRS front airbags may occur.

●

Hitting a curb, edge of pavement or hard sur-

face

●

Falling into or jumping over a deep hole

●

Landing hard or falling

●

The angle of vehicle tip-up is marginal.

●

The vehicle skids and hits a curb stone.

●

Collision from the side

●

Collision from the rear

●

Vehicle rollover

1-1. For safe use

■

Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield air-

bags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to a

collision from the side at certain angles, or a collision to the side of the vehicle body other

than the passenger compartment.

The SRS side airbags do not generally inflate if the vehicle is involved in a rear collision, if

it rolls over, or if it is involved in a low-speed side or low-speed frontal collision.

The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear

collision, if it pitches end over end, or if it is involved in a low-speed side or low-speed

frontal collision.

●

Collision from the side to the vehicle body

other than the passenger compartment

●

Collision from the side at an angle

●

Collision from the rear

●

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 system may not recognize him/her as a child. Factors which may affect this can
be the physique or posture.

: Never install a rear-facing child restraint system on the front passenger seat. A for-

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