Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
in ate during improper service. You can be injured
if you are close to an airbag when it in ates.
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 quali ed to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. 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, rollover sensor module, or airbag wiring
can affect the operation of the airbag system.
In addition, the vehicle has a passenger sensing
system for the right front 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
1-70

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).
SeePassenger Sensing System on page 1-65.
If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 7-2.
If the vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on page 5-68
for additional important information.Q:Because I have a disability, I have to get my
vehicle modi ed. How can I nd out whether
this will affect my airbag system?
A:If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.

Automatic Transmission Operation
The shift lever is located on the center console between
the front seats.
There are several different
positions for the shift lever.
P (Park):This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.{CAUTION:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park on page 2-33. If you are pulling a trailer,
seeTowing a Trailer on page 4-39.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must
fully apply the brakes rst and then press the
shift lever button before you can shift from
P (Park) when the ignition key is in ON/RUN.
2-27

If you cannot shift out of P (Park), ease pressure on
the shift lever and push the shift lever all the way into
P (Park) as you maintain brake application. Then press
the shift lever button and move the shift lever into another
gear. SeeShifting Out of Park on page 2-35.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
R (Reverse):Use this gear to back up.
At low vehicle speeds, you can also use R (Reverse)
to rock the vehicle back and forth to get out of snow, ice,
or sand without damaging the transmission. SeeIf
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-29for additional information.N (Neutral):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use N (Neutral) only. You can also
use N (Neutral) when the vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.

Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come on.
If it does not, you need to have the vehicle serviced.
SeeBrake System Warning Light on page 3-36for
more information.To release the parking brake, pull the release lever
located to the left of the steering wheel on the instrument
panel.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle begins to move.
To stop the chime, fully release the parking brake.
If you are towing a trailer and parking on a hill,
seeTowing a Trailer on page 4-39for more information.
