Seating and Safety Restraints
Seat-mounted side airbag system
WARNING: Do not place objects or mount equipment on or
near the airbag cover on the side of the seatbacks of the front
seats or in front seat areas that may come into contact with a
deploying airbag. Failure to follow these instructions may increase the
risk of personal injury in the event of a collision.
WARNING: Do not use accessory seat covers. The use of
accessory seat covers may prevent the deployment of the side
airbags and increase the risk of injury in an accident.
WARNING: Do not lean your head on the door. The side airbag
could injure you as it deploys from the side of the seatback.
WARNING: Do not attempt to service, repair, or modify the
airbag SRS, its fuses or the seat cover on a seat containing an
airbag. Contact your authorized dealer as soon as possible.
WARNING: All occupants of the vehicle should always wear
their safety belts even when an airbag SRS is provided.
