CAUTION
■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 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 safer for infants and children than the
front passenger seat. ( P. 64)
●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.
●Do not lean against the door, the roof side
rail or the front, side and rear pillars.

CAUTION
■SRS airbag precautions
●Do not strike or apply significant levels of force to the area of the SRS airbag
components. 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 residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes, are damaged or cracked, have them replaced by
any authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perfor m any of the following modifications with-
out consulting any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional. 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, seats or seat upholstery, front, side and rear pillars or roof side
rails
●Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment
●Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows, winches
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios (RF-transmitter)
and CD players

■Conditions under which the SRS airbags may deploy (inflate), other than a collision
(SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag)
The SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag may
also deploy if a serious impact occurs to the underside of your vehicle. Some exam-
ples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbags (SRS front airbags and SRS
seat cushion airbag)
The SRS front airbags and SRS seat cushion airbag 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 for-
ward deceleration of the vehicle, deployment of the SRS front airbags and SRS seat
cushion airbag may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover
