seat cushion, with their feet comfortably extended on the floor. Sitting
improperly can increase the chance of injury in a crash event. For
example, if an occupant slouches, lies down, turns sideways, sits forward,
leans forward or sideways, or puts one or both feet up, the chance of
injury during a crash is greatly increased.
WARNING: Sitting improperly out of position or with the seat
back reclined too far can take off weight from the seat cushion
and affect the decision of the front passenger sensing system, resulting
in serious injury or death in a crash.
Always sit upright against your seatback, with your feet on the floor.
The front passenger sensing system may detect small or medium objects
placed on the seat cushion. For most objects that are in the front
passenger seat, the passenger airbag will be disabled. Even though the
passenger airbag is disabled, the
Љpass airbag offЉ lamp may or may not
be illuminated according to the table below.
