Before driving
CAUTION
nSRS airbag precautions
lThe 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.
lImproperly seated and/or restrained infants and children can be killed or seri-
ously 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
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are the safest for infants and children.
(→P. 1 0 0 )
lIf the seat belt extender has been con-
nected to the driver's seat belt buckle but
the seat belt extender has not also been
fastened to the latch plate of the driver's
seat belt, the SRS driver's airbag system
will judge that the driver is wearing the seat
belt even though the seat belt has not been
connected. In this case, the driver's airbag
may not activate correctly in a collision,
resulting in death or serious injury in the
event of collision. Be sure to wear the seat
belt with the seat belt extender.

the knees of a front passenger.
lDo not drive the vehicle while the driver or
passenger have items resting on their

Before driving
CAUTION
nSRS airbag precautions
lIf the vinyl cover is put on the area where the SRS knee airbag will deploys, be
sure to remove it.
lDo not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags.
lDo not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 85.
Doing so can cause the SRS airbags to malfunction.
lDo not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
lIf breathing becomes difficult after the SRS airbag has 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
residue as soon as possible to prevent skin irritation.
lIf the areas where the SRS airbags are stored, such as the steering wheel pad and
front pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
lDo not attach anything to or lean anything
against areas such as the dashboard, steer-
ing wheel pad and lower portion of the
instrument panel.
These items can become projectiles when
SRS driver, front passenger and knee air-
bags deploy.
lDo not attach anything to areas such as the
door, windshield glass, side door glass,
front and rear pillars, roof side rail or assist
grip.
lDo not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and seri-
ously injure or kill you, should the SRS cur-
tain shield airbag deploy.

adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint system sits in
the front passenger seat, the system may recognize him/her as an

*4: Never install a rear-facing child restraint system on the front passen-
ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (→P.

*5: In case the indicator is not illuminated, consult this manual as for
installing the child restraint system properly. (→P. 1 0 4 )
CAUTION
nFront passenger occupant classification system precautions
Observe the following precautions regarding front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious injury.
lWear the seat belt properly.
lMake sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.
lMake 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 illuminated, disconnect the extender tongue from the seat belt buckle,
then 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 front passenger air-
bag, side airbag on the front passenger side and front passenger knee airbag may
not activate correctly, which could cause death or serious injury in the event of
collision.
lDo 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.
lDo not let a rear passenger lift the front passenger seat with their feet or press on
the seatback with their legs.
lDo not put objects under the front passenger seat.

Before driving
CAUTION
nFront passenger occupant classification system precautions
lDo 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 passenger’s airbags will not deploy 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
effectiveness of the seat belt system.
lIf an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. 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 cor-
rectly. If the “AIR BAG OFF” indicator still remain illuminated, either ask the pas-
senger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
lWhen it is unavoidable to install the 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. 1 0 4 )
lDo not modify or remove the front seats.
lDo 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 detection sys-
tem. In this case, contact your Lexus dealer immediately.
lChild restraint systems installed on the rear seat should not contact the front seat-
backs.
lDo not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
lDo not modify or replace the upholstery of the front seat.

Child restraint systems
Points to remember
Studies have shown that installing a child restraint on a rear seat is much
safer than installing one to the front passenger seat.
lChoose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
lFor installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (→P.
104)
Types of child restraints
Child restraint systems are classified into the following 3 types according
to the age and size of the child.
Rear facing ⎯ Infant seat/convertible seat
A child restraint system for a small child or baby must itself be properly
restrained on the seat with 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.
