ed while driving even though an adult or
someone larger than a small individual is
occupying the front passenger seat. Forc-
es acting on the seat may make the sys-

Re-position yourself.

Sit properly belted in a nearly upright
position with your back against the
seat backrest.
If performing any of the above corrective
steps is successful, the message
