DIC Operation and Displays
The DIC comes on when the ignition is on. After a
short delay the DIC will display the information
that was last displayed before the engine
was turned off.
If a problem is detected, a warning message will
appear on the display. Pressing the trip stem
will acknowledge any warning or service
messages. Pressing any of the DIC steering wheel
buttons — trip information, fuel information,
customization, or select button — will also
acknowledge any warnings or service messages.
You should take any message that appears on
the display seriously and remember that clearing
the message will only make the message
disappear, not correct the problem.
The DIC has different modes which can be
accessed by pressing the four DIC buttons located
on the steering wheel. These buttons are trip
information, fuel information, customization, and
select. The button functions are detailed in
the following pages.

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.

Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving on
page 302. By taking a few moments to read this
manual and get familiar with your vehicle’s
audio system, you can use it with less effort, as
well as take advantage of its features. While your
vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the
tone, and adjusting the speakers. Then, when
driving conditions permit, you can tune to
your favorite stations using the presets and
steering wheel controls if the vehicle has them.

{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. Here are some ways in which you can
help avoid distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD
player, CB radio, mobile telephone, or two-way
radio, make sure that it can be added by
checking with your dealer. Also, check federal
rules covering mobile radio and telephone
units. If sound equipment can be added, it is
very important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems
may interfere with the operation of sound
equipment that has been added.
Notice:The chime signals related to safety
belts, parking brake, and other functions of
your vehicle operate through the radio/
entertainment system. If that equipment is
replaced or additional equipment is added to
your vehicle, the chimes may not work. Make
sure that replacement or additional equipment
is compatible with your vehicle before installing
it. SeeAccessories and Modifications on
page 380.

Section 4 Driving Your Vehicle
301

Control of a Vehicle
You have three systems that make your
vehicle go where you want it to go. They are
the brakes, the steering, and the accelerator.
All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 380.
Braking
SeeBrake System Warning Light on page 206.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds
or more with another. Age, physical condition,
alertness, coordination, and eyesight all play a part.
So do alcohol, drugs, and frustration. But even in
three-fourths of a second, a vehicle moving at
60 mph (100 km/h) travels 66 feet (20 m). That
could be a lot of distance in an emergency, so
keeping enough space between your vehicle and
others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.
306

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.
