RC F_U

■

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

front seats, 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. 370)

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. 51)

■

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 will deploy in the event of a severe frontal colli-

sion.

■

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.

●

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.

■

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.

■

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

airbags)
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.

●

Collision from the side

●

Collision from the rear

●

Vehicle rollover

●

Collision from the side to the vehicle body

other than the passenger compartment

●

Collision from the side at an angle

●

Collision from the rear

●

Vehicle rollover

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. (

P. 58)

: In case the indicator light is not illuminated, consult this manual on how to install the

child restraint system properly. (

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 may 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).

●

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.

WARNING

■

Front passenger occupant classification system precautions

●

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. 60)

●

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.

●

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.

●

Do not place anything between the console box and front passenger seat. Other-

wise, the system may not detect the front passenger properly, leading to improper

operation of the airbags.

●

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.

●

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

Safety information for children

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.

Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.

Child restraint systems

Before installing a child restraint system in the vehicle, there are precautions
that need to be observed, different types of child restraint systems, as well as
installation methods, 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 follow the installation method that is in the operation manual
enclosed with the 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 depending on the age

and size of the child.

●

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.

●

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 windshield or between

the holder and the interior of the vehicle.

●

Place one child to a child restraint system and then secure the child with the harness

of the child restraint system.

■

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

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

ing, or an accident.

●

If the vehicle were to receive a strong impact from an accident, etc., it is possible 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 manufacturer and that the system is properly secured.

●

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.
