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.

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.

1-1. For safe use

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.

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. (

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. (

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.
