3-34 Seats and Restraints
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end or side sheet
metal, may keep the airbag system
from working properly. The
operation of the airbag system can
also be affected by changing or
moving any parts of the front seats,
safety belts, the airbag sensing and
diagnostic module, steering wheel,
instrument panel, roof-rail airbag
modules, ceiling headliner or pillar
garnish trim, front sensors, side
impact sensors, or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.In addition, the vehicle has a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM
covers, upholstery or trim, or with
GM covers, upholstery or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort enhancing pad
or device, installed under or on top
of the seat fabric, could also
interfere with the operation of the
passenger sensing system. This
could either prevent proper
deployment of the passenger
airbag(s) or prevent the passenger
sensing system from properly
turning off the passenger airbag(s).
See
Passenger Sensing System on
page 3‑29. If your vehicle needs to be modified
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.
See
Customer Assistance Offices
(U.S. and Canada) on page 13‑5 or
Customer Assistance Offices
(Mexico) on page 13‑5.

The following may correct an
emissions system malfunction:
.Check that the fuel cap is fully
installed. SeeFilling the Tank on
page 9‑55. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up. If one or more of these conditions
occurs, change the fuel brand used.
It will require at least one full tank of
the proper fuel to turn the light off.
See
Recommended Fuel on
page 9‑53.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Some local governments may have
programs to inspect the on-vehicle
emission control equipment. For the
inspection, the emission system test
equipment is connected to the
vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel next to the steering wheel.
See your dealer if assistance is
needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is running.
The vehicle is in ON/RUN for
keyed access, or service only
mode for keyless access and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.

If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning.
If both the ABS and the brake
system warning light are on, the
vehicle's antilock brakes are not
functioning and there is a problem
with the regular brakes. See your
dealer for service.
SeeBrake System Warning Light on
page 5‑20.
See Brake System Messages on
page 5‑36 for all brake related DIC
messages.Traction Off Light
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer.
This light comes on when the
Traction Control System (TCS) has
been turned off by pressing and
releasing the TCS/StabiliTrak
button.
This light also comes on and the
system turns off if there is a problem
with the traction control system.
If the light comes on and stays on
for an extended period of time while
the system is turned on, the vehicle
needs service. See
Traction Control System (TCS)

Traction Control System
(TCS)/StabiliTrak®Light
The Traction Control System (TCS)/
StabiliTrak light comes on briefly
when the engine is started.
If the light does not come on, have
the vehicle serviced by the dealer.
If the system is working normally,
the indicator light turns off. If the light is on while certain DIC
messages display, this indicates
that the TCS and StabiliTrak
systems are not working or are
disabled.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. Check
the DIC messages to determine
which feature(s) is no longer
functioning and whether it is
because of the driver turning off the
feature(s), or because the system is
not working properly and the vehicle
requires service.
If the TCS is disabled, wheel spin is
not limited. If the StabiliTrak system
is disabled, the system does not aid
in maintaining directional control of
the vehicle.
If the indicator/warning light is on
and flashing, the TCS or the
StabiliTrak system is actively
working. Check the DIC messages
for details to determine which
system is working. If a message
appears in the DIC, the system may
be limiting wheel spin and aiding in
maintaining directional control of the
vehicle.
