to normal operation; the doors can be
locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle,
such as the fuel system, brake and
steering systems, etc. Even if the
vehicle appears to be drivable after
a moderate crash, there may be
concealed damage that could make
it difficult to safely operate the
vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation. Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.
Airbags are designed to inflate
only once. After an airbag inflates,
you will need some new parts for
the airbag system. If you do not
get them, the airbag system will
not be there to help protect you in
another crash. A new system will
include airbag modules and
possibly other parts. The service
manual for the vehicle covers the
need to replace other parts.
. The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
See Vehicle Data Recording and
Privacy 0332 and
Event Data Recorders 0333.
. Let only qualified technicians
work on the airbag system.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing System
The vehicle has a passenger sensing
system for the front outboard
passenger position. The passenger
airbag status indicator will light on
the overhead console when the vehicle
is started.
The words ON and OFF, and the
symbols for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, and the symbol for
on or off, will be visible. See Passenger
Airbag Status Indicator 099.
The passenger sensing system turns
off the front outboard passenger
frontal airbag and knee airbag under
certain conditions. No other airbag is
affected by the passenger sensing
system.

and stays on at start up, there is a
brake problem. Have the brake system
inspected right away.
If the light comes on while driving,
pull off the road and stop carefully.
The brake system has electric brake
boost. Vehicle speed may be limited
when the brake system warning light

take longer to stop. If the light is still
on, have the vehicle towed for service.
See Towing the Vehicle 0291.

pulled off the road and carefully
stopped, have the vehicle towed for
service.
