SEATS AND RESTRAINTS 79
{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.
You can lock the doors, turn off the interior lamps, and turn off the hazard
warning flashers by using the controls
for those features.
{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 0325 and Event Data
Recorders 0325.
. 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.
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.

up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. SeeFuel0240.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0243.
See your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service
Only Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
Brake System Warning
Light
The vehicle brake system consists of
two hydraulic circuits. If one circuit is
not working, the remaining circuit can still work to stop the vehicle. For
normal braking performance, both
circuits need to be working.
If the warning light comes on, there is
a problem with the braking system.
Have the brake system inspected
right away.
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 you if there is a
problem.
If the light comes on and stays on,
there is a base brake problem.
{Warning
The brake system might not be
working properly if the brake
system warning light is on. Driving

possible. See
Electric Parking Brake
0 205. If a message displays in the
Driver Information Center (DIC), see
Brake System Messages 0142.
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
