The vehicle may or may not have seat!mounted sideimpact airbags. The vehicle has roof-rail airbags. SeeAirbag Systemon page 2!74. Seat!mounted sideimpact airbags and roof-rail airbags are intended toinflate in moderate to severe side crashes. In addition,these roof-rail airbags are intended to inflate during arollover or in a severe frontal impact. Seat!mounted sideimpact airbags and roof-rail airbags will inflate if thecrash severity is above the system's designedthreshold level. The threshold level can vary withspecific vehicle design.
Roof-rail airbags are not intended to inflate in rearimpacts. A seat!mounted side impact airbag is intendedto deploy on the side of the veicle that is struck. Bothroof-rail airbags will deploy when either side of thevehicle is struck or if the sensing system predicts thatthe vehicle is about to roll over, or in a severe frontalimpact.
In any particular crash, no one can say whether anairbag should have inflated simply because of thedamage to a vehicle or because of what the repaircosts were. For frontal airbags, inflation is determinedby what the vehicle hits, the angle of the impact, andhow quickly the vehicle slows down. For seat!mountedside impact and roof-rail airbags, deployment isdetermined by the location and severity of the sideimpact. In a rollover event, roof-rail airbag deploymentis determined by the direction of the roll.
What Makes an Airbag Inflate?
In a deployment event, the sensing system sends anelectrical signal triggering a release of gas from theinflator. Gas from the inflator fills the airbag causing thebag to break out of the cover and deploy. The inflator,the airbag, and related hardware are all part of theairbag module.
Frontal airbag modules are located inside the steeringwheel and instrument panel. For vehicles with seat!mounted side impact airbags, there are airbagsmodules in the side of the front seatbacks closest to thedoor. For vehicles with roof-rail airbags, there are airbagmodules in the ceiling of the vehicle, near the sidewindows that have occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,even belted occupants can contact the steering wheelor the instrument panel. In moderate to severe sidecollisions, even belted occupants can contact the insideof the vehicle.
Airbags supplement the protection provided by safetybelts. Frontal airbags distribute the force of the impactmore evenly over the occupant's upper body, stoppingthe occupant more gradually. Seat!mounted side impactand roof-rail airbags distribute the force of the impactmore evenly over the occupant's upper body.

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

Ignition Positions
The ignition switch hasfour different positions.
To shift out of P (Park), the ignition must be in ON/RUNor ACC/ACCESSORY and the regular brake pedal mustbe applied.
A (LOCK/OFF) :This position locks the ignition.It may also lock the steering wheel and automatictransmission. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shiftlever must be in P (Park) to turn the ignition switchto LOCK/OFF.
The steering may bind with the wheels turned off center.If this happens, move the steering wheel from right toleft while turning the key to ACC/ACCESSORY. If thisdoesn't work, then the vehicle needs service.
Notice:Using a tool to force the key to turn in theignition could cause damage to the switch or breakthe key. Use the correct key, make sure it is all theway in, and turn it only with your hand. If the keycannot be turned by hand, see your dealer/retailer.
B (ACC/ACCESSORY) :This position lets things likethe radio and the windshield wipers operate while theengine is off. Use this position if the vehicle must bepushed or towed.

Cruise Control
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
With cruise control, a speed of about 40 km/h (25 mph)or more can be maintained without keeping your foot onthe accelerator. Cruise control does not work at speedsbelow about 40 km/h (25 mph).
When the brakes are applied, cruise control isturned off.
For vehicles with an Allison®or Hydra!Matic 6!speedautomatic transmission, see“Grade Braking and CruiseGrade Braking (Allison Transmission) underTow/HaulModeon page 3!36for an explanation of how cruisecontrol interacts with the Range Selection Mode, tow/haul and grade braking systems.
If the vehicle has StabiliTrak®, and the system beginsto limit wheel spin, cruise control will automaticallydisengage. SeeStabiliTrak®Systemo n p a g e 6!6.When road conditions allow the cruise control to besafely used again, it can be turned back on.
