86 SEATS AND RESTRAINTS
{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
After turning the ignition off and then
on again, the fuel system will return 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 0352 and Event Data
Recorders 0352.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

Brake System Warning
Light
The vehicle brake system consists of
electronically controlled hydraulic
brake circuits. If a fault is detected,
valves are adjusted to allow the brake
pedal to push brake fluid directly into
the hydraulic brake circuits. When a
fault occurs, the brake system warning
light comes on, and Driver
Information Center (DIC) messages
may display. Vehicle speed may also
be limited and the amount of brake
pedal force applied may need to
increase. Have the vehicle brake
system serviced as soon as possible.
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn if there is a
problem.
The brake system warning light may
also come on when the parking brake
is set, if the vehicle has low brake
fluid, or if the brakes are severely
faded. See Brake Fluid 0268. If the
brakes are overheated, DIC messages
may display, and the vehicle speed
may be limited. If the brake fluid is
not low, if the brakes are not
overheated, and if the parking brake is
fully released, then the vehicle has a
brake problem. Have the vehicle brake
system serviced as soon as possible. If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal may go closer to the
floor. It could take longer to stop.
If the light is still on, have the vehicle
towed for service. See
Towing the
Vehicle 0312.
{Warning
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning light
on can lead to a crash. If the light is
still on after the vehicle has been
pulled off the road and carefully
stopped, have the vehicle towed for
service.

Electric Parking Brake
Light
MetricEnglish
This light comes on when the parking
brake is applied. If the light continues
flashing after the parking brake is
released, or while driving, there is a
problem with the Electric Parking
Brake system. A message may also
display in the Driver Information
Center (DIC).
If the light does not come on,
or remains flashing, see your dealer.
Service Electric Parking
Brake Light
On some vehicles the service electric
parking brake light should come on
briefly when the vehicle is started.
If it does not come on, have it fixed so
it will be ready to warn if there is a
problem. For vehicles with the
reconfigurable cluster, this light may
not come on when the vehicle is
started.
If this light stays on, the vehicle
should be taken to a dealer as soon as
possible. See Electric Parking Brake
0 201. A message may also display in
the Driver Information Center (DIC).
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the system.
If the ABS light stays on, or comes on
again while driving, the vehicle needs
service. A chime may also sound when
the light comes on steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but the
antilock brakes are not functioning.

amber.
This light is amber and flashes as a
Lane Departure Warning (LDW) alert,
to indicate that the lane marking has
been crossed.
See Lane Keep Assist (LKA) 0234.
