CAUTION
SRS airbag precautions
Do not hang coat hangers or hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the
SRS curtain shield airbags deploy.
If a vinyl cover is put on the area where the SRS knee airbag will deploy, be
sure to remove it.
Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags. Such accessories
may prevent the side airbags from activating correctly, disable the system or
cause the side airbags to inflate accidentally, resulting in death or serious
injury.
Do not allow anyone to kneel on the pas-
senger seats toward the door or put their
head or hands outside the vehicle.
Do not attach anything to or lean any-
thing against areas such as the dashboard,
steering wheel pad and lower portion of
the instrument panel.
These items can become projectiles when
the SRS driver, front passenger and knee
airbags deploy.
Do not attach anything to areas such as a
door, windshield glass, side door glass,
front or rear pillar, roof side rail and assist
grip. (Except for the speed limit sticker
P. 533)
