Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-16.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. 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 qualied 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 your 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, or airbag wiring
can affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position,
which includes sensors that are part of the
passenger’s seat. The passenger sensing system
may not operate properly if the original seat
trim is replaced with non-GM covers, upholstery

Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam, push the turn signal lever away from you.
When the high beams are
on, this light on the
instrument panel cluster
will also be on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.
Windshield Wipers
Use this lever, located on the right side of the steering
wheel, to operate the windshield wipers.
9(Off):Move the lever to this position to turn off the
windshield wipers.
&(Intermittent; Speed Sensitive Wipers):Move the
lever to this position for intermittent or speed sensitive
operation. The amount of delay time varies between
wiping cycles due to the delay setting selected or
the speed of the vehicle. As vehicle speed is increased
or decreased, the wiper interval will also increase or
decrease.
3-8

Cruise Control
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below
25 mph (40 km/h).
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your 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.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
The cruise control buttons
are located on the
outboard side of the
steering wheel.
J(On/Off):Press this button to turn the cruise control
system on and off.

Outlet Adjustment
Use the thumbwheels located next to and below the air
outlets to change the direction of the airow and to
open and close the outlets.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment lter. The lter removes certain particles
from the air, including pollen and dust particles.
Reductions in airow, which may occur more quickly
in dusty areas, indicate that the lter needs to be
replaced early.The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled Maintenance
on page 6-4for replacement intervals. See your
dealer/retailer for details on changing the lter.
To nd out what type of lter to use, seeMaintenance
Replacement Parts on page 6-14.
To access the passenger compartment air lter you
must go through the glove box.
1. Open the glove box and remove all articles from
the inside.
2. Tilt the glove box door down by squeezing on each
side of the glove box until the door can be lowered
from its track. Lower the glove box door.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
The DIC display gives you the status of many of your
vehicle’s systems. The DIC is also used to display driver
personalization menu modes and warning/status
messages. All messages will appear in the DIC display,
located at the bottom of the instrument panel cluster.
The DIC buttons are
located on the left side of
the steering wheel.
INFO (Information):Press this button to scroll through
the vehicle information mode displays.
r(Reset):Press this button to reset some vehicle
information mode displays, select a personalization menu
mode setting, or acknowledge a warning message.

Antilock Brake System (ABS)
Your vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will come
on briey when you
start your vehicle.
When you start the engine, or when you begin to drive
away, ABS will check itself. You might hear a
momentary motor or clicking noise while this test is
going on, and you might even notice that the brake
pedal moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you will not have time to apply the brakes if
that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might feel
a slight brake pedal pulsation or notice some noise, but
this is normal.

The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the POWER STEERING message
comes on, contact your dealer/retailer for service
repairs. SeeDIC Warnings and Messages on page 3-43.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there is no traction, inertia will keep
the vehicle going in the same direction. If you have ever
tried to steer a vehicle on wet ice, you will
understand this.
The traction you can get in a curve depends on the
condition of the tires and the road surface, the angle at
which the curve is banked, and your speed. While you
are in a curve, speed is the one factor you can control.Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both control
systems — steering and braking — have to do their work
where the tires meet the road. Unless you have antilock
brakes, adding the hard braking can demand too much of
those places. You can lose control.
The same thing can happen if you are steering through
a sharp curve and you suddenly accelerate. Those
two control systems — steering and acceleration — can
overwhelm those places where the tires meet the road
and make you lose control. SeeTraction Control System
(TCS) on page 4-6,Enhanced Traction System (ETS) on
page 4-9, andElectronic Stability Control (ESC) on
page 4-10.
What should you do if this ever happens? Ease up on
the brake or accelerator pedal, steer the vehicle the way
you want it to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you will want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while the
front wheels are straight ahead.
