WARNING
■SRS airbag precautions
●If a vinyl cover is put on the area where the SRS driver’s knee airbag will
deploy, be sure to remove it.
●Do not use seat accessories which cover the parts where the SRS side
airbags and SRS seat cushion airbag inflate as they may interfere with
inflation of the SRS airbags. Such accessories may prevent the side air-
bags and seat cushion airbag from activating correctly, disable the system
or cause the side airbags and seat cushion airbag to inflate accidentally,
resulting in death or serious injury.
●Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS air-
bags 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 pillars garnishes, are damaged or cracked, have
them replaced by your Toyota 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 passenger'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 Toyota 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, 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
