Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,ceiling or pillar garnish trim, theinside rearview mirror, front sensors,side impact sensors, or airbagwiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module and airbagwiring.
In addition, the vehicle has apassenger sensing system for thefront outboard passenger position,which includes sensors that are partof the passenger's seat. Thepassenger sensing system may notoperate properly if the original seat
trim is replaced with non-GMcovers, upholstery or trim, or withGM covers, upholstery or trimdesigned for a different vehicle. Anyobject, such as an aftermarket seatheater or a comfort enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properlyturning off the passenger airbag(s).SeePassenger Sensing System063.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0318for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andhave questions about whether themodifications will affect the vehicle'sairbag system, or if you havequestions about whether the airbagsystem will be affected if the vehicle
is modified for any other reason, callCustomer Assistance. SeeCustomer Assistance Offices0366.
Airbag System Check
The airbag system does not needregularly scheduled maintenance orreplacement. Make sure the airbagreadiness light is working. SeeAirbag Readiness Light099.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any
opened or broken airbag
coverings, have the airbag
covering and/or airbag module
replaced. For the location of the

Speedometer
The speedometer shows thevehicle's speed in either kilometersper hour (km/h) or miles perhour (mph).
Odometer
The odometer shows how far thevehicle has been driven, in eitherkilometers or miles.
Trip Odometer
The trip odometer shows how farthe vehicle has been driven sincethe trip odometer was last reset.
The trip odometer is accessed andreset through the Driver InformationCenter (DIC). SeeDriverInformation Center (DIC)0108.
Tachometer
The tachometer displays the enginespeed in revolutions perminute (rpm).
Caution
If the engine is operated with the
rpm’sinthewarningareaatthe
high end of the tachometer, the
vehicle could be damaged, and
the damage would not be covered
by the vehicle warranty. Do not
operate the engine with the rpm’s
in the warning area.
Fuel Gauge
When the ignition is on, the fuelgauge shows how much fuel is leftin the fuel tank. When the indicator
nears empty, a message in theDriver Information Center (DIC)displays. SeeFuel SystemMessages011 5.Thevehiclestillhas a little fuel left, but the vehicleshould be fueled soon. An arrow onthe fuel gauge indicates the side ofthe vehicle the fuel door is on.
Here are four things that someowners ask about. These arenormal and do not indicate aproblem with the fuel gauge:
.At the service station, the gaspump shuts off before the gaugereads full.
.It takes a little more or less fuelto fill up than the gaugeindicated. For example, thegauge may have indicated thefuel tank was half full, but itactually took a little more or lessthan half the fuel tank's capacityto fill it.
.The indicator moves a little whileturning a corner or speeding up.
.The gauge goes back to emptywhen the ignition is turned off.

Airbag Readiness Light
This light shows if there is anelectrical problem with the airbagsystem. The system check includesthe airbag sensor(s), passengersensing system, the pretensioners,the airbag modules, the wiring, andthe crash sensing and diagnosticmodule. For more information on theairbag system, seeAirbag System057.
The airbag readiness light comes onfor several seconds when thevehicle is started. If the light doesnot come on then, have it fixedimmediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
Passenger Airbag Status
Indicator
This vehicle has a passengersensing system. SeePassengerSensing System063for importantsafety information. The rearviewmirror has a passenger airbagstatus indicator.

If the word ON is lit on thepassenger airbag status indicator, itmeans that the front outboardpassenger frontal airbag and kneeairbag are allowed to inflate.
If the word OFF is lit on thepassenger airbag status indicator, itmeans that the passenger sensingsystem has turned off the frontoutboard passenger frontal airbagand knee airbag.
If, after several seconds, both statusindicator lights remain on, or if thereare no lights at all, there may be a
problem with the lights or thepassenger sensing system. Seeyour dealer for service.

If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness

Malfunctions are often indicated bythe system before any problem isnoticeable. Being aware of the lightand seeking service promptly whenit comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’sabilitytopass
an Emissions Inspection/
Maintenance test. See

If the light is flashing :Amalfunction has been detected thatcould damage the emission controlsystem and increase vehicleemissions. Diagnosis and servicemay be required.
To h e l p p r e v e n t d a m a g e , r e d u c evehicle speed and avoid hardaccelerations and uphill grades.
If the light continues to flash, find asafe place to park. Turn the vehicleoff and wait at least 10 secondsbefore restarting the engine. If thelight is still flashing, follow theprevious guidelines and see yourdealer for service as soon aspossible.
If the light is on steady :Amalfunction has been detected.Diagnosis and service may berequired.
Check the following:

Emissions Inspection and
Maintenance Programs
If the vehicle requires an EmissionsInspection/Maintenance test, thetest equipment will likely connect tothe vehicle's Data LinkConnector (DLC).
The DLC is under the instrumentpanel to the left of the steeringwheel. Connecting devices that arenot used to perform an EmissionsInspection/Maintenance test or toservice the vehicle may affectvehicle operation. SeeAdd-OnElectrical Equipment0268.Seeyour dealer if assistance is needed.
The vehicle may not passinspection if:
.The light is on when the engineis running.
.The light does not come onwhen the ignition is inService Mode.
.Critical emission control systemshave not been completelydiagnosed. If this happens, thevehicle would not be ready forinspection and might requireseveral days of routine drivingbefore the system is ready forinspection. This can happen ifthe 12-volt battery has recentlybeen replaced or run down, or ifthe vehicle has been recentlyserviced.
See your dealer if the vehicle willnot pass or cannot be made readyfor the test.
