Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.There are parts of the airbag system in several placesaround the vehicle. Your dealer/retailer and the servicemanual have information about servicing the vehicleand the airbag system. To purchase a service manual,seeService Publications Ordering Informationonpage 9!17.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q: Is there anything I might add to or change aboutthe vehicle that could keep the airbags fromworking properly?
A:Yes. If you add things that change the vehicle'sframe, bumper system, height, front end or sidesheet metal, they may keep the airbag system fromworking properly. Changing or moving any parts ofthe front seats, safety belts, the airbag sensing anddiagnostic module, steering wheel, instrument panel,roof-rail airbag modules, ceiling headliner or pillargarnish trim, overhead console, front sensors, sideimpact sensors, rollover sensor module, or airbagwiring can affect the operation of the airbag system.
In addition, the vehicle may have a passengersensing system for the right front passengerposition, which includes sensors that are part of thepassenger seat. The passenger sensing systemmay not operate properly if the original seat trim isreplaced with non-GM covers, upholstery or trim,or with GM covers, upholstery or trim designed for a

different vehicle. Any object, such as an aftermarketseat heater or a comfort enhancing pad or device,installed under or on top of the seat fabric, couldalso interfere with the operation of the passengersensing system. This could either prevent properdeployment of the passenger airbag(s) or preventthe passenger sensing system from properly turningoff the passenger airbag(s). SeePassenger SensingSystem on page 2!84.
If you have any questions, call CustomerAssistance. The phone numbers and addresses forCustomer Assistance are in Step Two of theCustomer Satisfaction Procedure in this manual.SeeCustomer Satisfaction Procedure on page 9!2.
If the vehicle has rollover roof-rail airbags, seeDifferent Size Tires and Wheelson page 7!75foradditional important information.
Q: Because I have a disability, I have to get myvehicle modified. How can I find out whether thiswill affect my airbag system?
A:If you have questions, call Customer Assistance.The phone numbers and addresses for CustomerAssistance are in Step Two of the CustomerSatisfaction Procedure in this manual. SeeCustomer Satisfaction Procedure on page 9!2.
In addition, your dealer/retailer and the service manualhave information about the location of the airbagsensors, sensing and diagnostic module andairbag wiring.

If the driver's side power door lock switch is pressedwhen the driver's door is open and the key is in theignition, all of the doors will lock and then the driver'sdoor will unlock.
If the passenger's side power door lock switch ispressed when the front passenger's door is open andthe key is in the ignition, all of the doors will lock andthen the front passenger's door will unlock.
Liftgate/Liftglass
{WARNING:
It can be dangerous to drive with the liftglass or
liftgate open because carbon monoxide (CO) gas
can come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death.
If you must drive with the liftglass or liftgate open,
or if electrical wiring or other cable connections
must pass through the seal between the body and
the liftglass or liftgate:
.Make sure all other windows are shut.
.Turn the fan on your heating or cooling
system to its highest speed with the
recirculation mode off. That will force outside
air into your vehicle. SeeDual Automatic
Climate Control System on page 4!20.
.If you have air outlets on or under the
instrument panel, open them all the way.
.If your vehicle is equipped with a power
liftgate, disable the power liftgate function.

The seven-wire harness contains the followingtrailer circuits:
.Yellow: Left Stop/Turn Signal
.Dark Green: Right Stop/Turn Signal
.Brown: Taillamps
.White: Ground
.Light Green: Back-up Lamps
.Red: Battery Feed*
.Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in theunderhood electrical center, but the wires are notconnected. They should be connected by yourdealer/retailer or a qualified service center.

Trailer Recommendations
Subtract the hitch loads from the Cargo Weight Rating(CWR). CWR is the maximum weight of the load thevehicle can carry. It does not include the weight of thepeople inside, but you can figure about 150 lbs. (68 kg)for each passenger. The total cargo load must not bemore than the vehicles CWR.
Weigh the vehicle with the trailer attached, so theGVWR or GAWR are not exceeded. If using aweight-distributing hitch, weigh the vehicle without thespring bars in place.
The best performance is obtained by correctlyspreading out the weight of the load and choosing thecorrect hitch and trailer brakes.
For more information seeTowing a Traileronpage 6!42.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to the vehicleunless you check with your dealer/retailer first.Some electrical equipment can damage the vehicleand the damage would not be covered by thevehicle's warranty. Some add-on electricalequipment can keep other components fromworking as they should.
Add-on equipment can drain the vehicle battery, even ifthe vehicle is not operating.
The vehicle has an airbag system. Before attempting toadd anything electrical to the vehicle, seeServicingYour Airbag-Equipped Vehicleon page 2!89andAdding Equipment to Your Airbag-Equipped Vehicleonpage 2!89.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuitbreaker and a fuse. If the motor overheats due to heavysnow, etc., the wiper will stop until the motor cools.If the overload is caused by some electrical problem,have it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and otherpower accessories. If the current load is too heavy, thecircuit breaker opens and then closes after a cool downperiod, protecting the circuit until the problem is fixed orgoes away.
Fuses and Circuit Breakers
If the vehicle is a Two-mode Hybrid, see the Two-modeHybrid manual for more information.
The wiring circuits in the vehicle are protected fromshort circuits by a combination of fuses, circuit breakersand fusible thermal links. This greatly reduces thechance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If theband is broken or melted, replace the fuse. Be sure youreplace a bad fuse with a new one of the identical sizeand rating.
If you ever have a problem on the road and don't havea spare fuse, you can borrow one that has thesame amperage. Just pick some feature of your vehiclethat you can get along without–like the radio orcigarette lighter–and use its fuse, if it is thecorrect amperage. Replace it as soon as you can.
