Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of 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.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors.
If you have any questions about this,
you should contact Customer Assistance
before you modify your vehicle. The phone
numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure
on page 526.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, the inside review mirror,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted airbag modules, or airbag
wiring can affect the operation of the airbag
system. 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. SeeCustomer

Tilt Wheel
The steering wheel should be adjusted before
you drive.
The tilt lever is located
to the left of the steering
column, under the
turn signal lever.
It can be raised to the highest level to give
your legs more room when you enter and exit
the vehicle.
To tilt the wheel, hold the steering wheel and pull
the lever toward you. Move the steering wheel
to a comfortable level, then release the lever
to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane Change Signals
23Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
NWindshield Wipers
JWindshield Washer
ICruise Control

Cruise Control
Your vehicle has cruise
control. The controls are
located on the end of
the turn signal/
multifunction lever.
R(On):Move the switch to this position to turn
the cruise control system on.
S(Resume/Accelerate):Move the switch to this
position to resume a set speed or to accelerate.
T(Set):Press this button, located at the end of
the lever, to set a speed.
9(Off):Move the switch to this position to turn
the cruise control system off and cancel memory
of a set speed.With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
If you apply the brakes, the cruise control shuts off.
{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.

Select Button
r
(Select):Press the select button to reset
certain DIC functions, turn off or acknowledge
messages on the DIC display, and set your
customization settings. For example, this button
will allow you to reset the trip odometers, turn
off the FUEL LEVEL LOW message, and enables
you to scroll through and select the language
in which the DIC information will appear.
DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed to correct the
condition. Multiple messages may appear one
after another.
Some messages may not require immediate
action. Press any of the DIC buttons on the
steering wheel or the trip odometer reset stem on
the instrument panel cluster to acknowledge
that you received the messages and to clear them
from the display.Some messages cannot be cleared from the
display because they are more urgent. These
messages require action before they can be
removed from the DIC display. Take any messages
that appear on the display seriously and remember
that clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
CHANGE ENGINE OIL
This message displays when the engine oil needs
to be changed and service is required for your
vehicle. SeeScheduled Maintenance on page 507
andEngine Oil on page 394for more information.
Also seeEngine Oil Life System on page 398
for information on how to reset the message. This
message clears itself after 10 seconds until the
next ignition cycle.

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
front wheel and at both rear wheels.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, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
308

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 your 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 anti-lock work for you.
You may feel the brakes vibrate, or you may notice
some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Locking Rear Axle
If your vehicle has this feature, your locking rear
axle can give you additional traction on snow, mud,
ice, sand or gravel. It works like a standard axle
most of the time, but when one of the rear wheels
has no traction and the other does, this feature will
allow the wheel with traction to move the vehicle.
StabiliTrak®System
Your vehicle is equipped with StabiliTrak®,
Electronic Stability Control (ESC) which combines
antilock brake, traction and stability control systems
and helps the driver maintain directional control of
the vehicle in most driving conditions.
Traction control activates when the controller
senses wheel spin. StabiliTrak
®will selectively
apply the brakes and reduce engine torque to help
regain traction.
Stability control activates when the controller
senses a discrepancy between your intended path
and the direction the vehicle is travelling.
StabiliTrak
®selectively applies braking pressure at
any one of the vehicle’s brakes to help guide the
vehicle in the direction which you are steering.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic
checks to insure there are no problems. You may
hear or feel the system working. This is normal and
does not mean there is a problem with your vehicle.
If driving conditions delay system initialization, the
STABILITRAK NOT READY message may be
displayed. If this is the case, your vehicle does not
need servicing.

Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning,
you can steer but it will take much more effort.
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 your 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 accelerate. Both control
systems — steering and acceleration — have to
do their work where the tires meet the road.
Adding the sudden acceleration can demand too
much of those places. You can lose control.
What should you do if this ever happens? Ease up
on the 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 your front wheels are straight ahead.
Try to adjust your speed so you can “drive” through
the curve. Maintain a reasonable, steady speed.
Wait to accelerate until you are out of the curve,
and then accelerate gently into the straightaway.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 380.
