SRS airbag precautions
●
The SRS front passenger airbag also deploy s with considerable force, and can cause
death or serious injury especially if the fron t 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 infant s 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 chil d 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 se ats are safer for infants an d children than the front
passenger seat. ( P. 58)●
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.

SRS airbag precautions ●
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. ●
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 seats 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 and lower po rtion of the instru-
ment panel.
These items can become projectiles when the
SRS driver, front passeng er and knee airbags
deploy. ●
Do not attach anything to areas such as a
door, windshield, side windshield, front or rear
pillar, roof side rail and assist grip.

There is a malfunction in the system
* 1
: The system judges a person of adult size as an adult. When a smaller adult sits in
the front passenger seat, the system ma y not recognize him/her as an adult
depending on his/her physique and posture.
* 2
: In the event the front passenger is wearing a seat belt.
* 3
: In the event the front passenger does not wear a seat belt
* 4
: 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.
* 5
: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint sy stem should only be inst alled on the front passenger
seat when it is unavoidable. ( P. 58)
* 6
: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. ( P. 60)Indicator/

Front passenger occupant classification system precautions ●
Do not recline the front passeng er seatback so far that it touches a rear seat. This may
cause the “AIR BAG OFF” indicator light to be illuminated, whic h indicates that the
SRS airbags for th e front passenger will no t activate in the even t 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 fron t 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 remain s illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the fron t passenger seat fully
rearward. ●
When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild 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 indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.●
Child restraint systems insta lled on the rear se at 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 cons ole box and front passenger seat. Other-
wise, the system may not de tect the front passenger pr operly, 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 avoi d 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 wh en 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.

or other features of the vehi cle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

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 type s of child restraint systems, as well as
installation methods, etc., written in this manual.
