■While driving
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head re straint, increasing the risk of death or
serious injury to the driver or passenger.

Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident. The adjustment
mechanism may also be damaged.

not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.

SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause significant injury to the occupants. They
work together with the seat belts to he lp reduce the risk of death or serious
injury.
Front airbags
Driver airbag/front passenger airbag
Can help protect the head and ches t of the driver and front passen-
ger from impact with interior components.
Knee airbags
Can help provide driver and front passenger protection.
Side and curtain shield airbags
Side airbags
Can help protect the torso of the front seat occupants.
Curtain shield airbags

Airbag system componentsThe main SRS airbag system componen ts are shown above. The SRS air-
bag system is controlled by the airb ag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants. Knee airbags
