WARNING
■SRS airbag precautions
● If breathing becomes difficult after the SRS airbags have deployed, open a
door or side 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 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, roof side rails, front door panels, front door trims or front door
speakers
● Modifications to the front door panel (such as making a hole in it)
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment

winches or roof luggage carrier
