{CAUTION:
·On winding roads, ACC may not detect a
vehicle ahead. You could crash into a
vehicle ahead of you. Do not use ACC on
winding roads.
·In heavy stop-and-go traffic, ACC may not
have time to slow your vehicle enough to
avoid a collision because of the rapidly
changing traffic conditions. Do not use
ACC in heavy stop-and-go traffic.
·On slippery roads, fast changes in tire
traction can cause needless wheel
spinning, and you could lose control. Do
not use cruise control on slippery roads.
·When visibility is low, such as in fog, rain
or snow, you can not tell how far away
things are and ACC performance is limited.
There may not be enough distance to
adapt to the changing traffic conditions.
Do not use cruise control when visibility
is low.Some of the ACC controls
are located on the end of
the multifunction lever.
9(Off):This position turns the system off.
R(On):This position turns the system on.
S(Resume/Increase):Push the switch to this symbol
to make the vehicle resume to a previously set speed
or to increase the set speed when ACC is already active.
T(Set/Decrease):Press this button to set the
speed or to decrease the set speed when ACC is
already active.

Selecting the Follow Distance (GAP)
When ACC detects a slower moving vehicle, it will
adjust your vehicle's speed and maintain the follow
distance (gap) you select.
Use the GAP button on
the steering wheel to
adjust the follow distance.
Press the top of the button to increase the distance or
the bottom of the button to decrease the distance.
The ®rst button press will show you the current follow
distance setting on the HUD. Your current follow
distance setting will be maintained until you change it.
There are six follow distances to choose from. The
follow distance selection ranges from near to far
(1 second to 2 seconds follow time).The distance maintained for a selected follow distance
will vary based on vehicle speed. The faster the
vehicle speed the further back you will follow. Consider
traffic and weather conditions when selecting the
follow distance. The range of selectable distances may
not be appropriate for all drivers and driving conditions.
If you choose to travel at a distance farther than
ACC allows, disengage ACC and drive manually.
A graphic on the HUD indicates the selected follow
distance. This picture shows a maximum follow distance.
The vehicles will move closer as you select a smaller
follow distance.

The HUD controls are
located to the left of the
steering wheel.
+
!- (Brightness):This button is used to adjust the
brightness of the HUD and the instrument panel cluster.
DIMMER:This button is used to select the HUD or
the instrument panel cluster to adjust the brightness.
HUD:This button is used to adjust the vertical position
of the HUD display.
To adjust the HUD so you can see it properly, do the
following:
1. Adjust the seat to a comfortable driving position. If
you change your seat position later, you may have
to re-adjust your HUD.2. Start your engine and press the top or bottom
of the HUD button to center the HUD image in
your view.
The HUD image can only be adjusted up and down,
not side-to-side.
3. Press the DIMMER button until the DIC reads HUD
DIMMING. Then use the brightness button to adjust
the desired intensity.
The brightness of the HUD image is determined by the
light conditions in the direction your vehicle is facing
and where you have the HUD set. If you are facing a
dark object or a heavily shaded area, your HUD
may anticipate that you are entering a dark area and
may begin to dim.
To turn off the HUD, press the brightness button down
until the image disappears.
Polarized sunglasses could make the HUD image
harder to see.
As light shines out from the HUD, it is possible for light
to shine back in. In rare occurrences, when the sun
is at a speci®c angle and position, the sun's rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle's angle to the
sun changes.

The anti-lock system 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.Remember: Anti-lock 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 anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down ®rmly and let anti-lock work for you. You may hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.

Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº 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 Ð steering and acceleration Ð 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. See
Traction Control
System (TCS) on page 4-9.
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 ªdriveº 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.
4-13

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
ªoverdrivingº those conditions. But skids are always
possible.
The three types of skids correspond to your vehicle's
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration
skid, too much throttle causes the driving wheels
to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
Remember: Any traction control system helps avoid only
the acceleration skid. If your TCS system is off, then
an acceleration skid is also best handled by easing your
foot off the accelerator pedal.If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety,
you will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration
or braking (including engine braking by shifting to a
lower gear). Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues Ð such as enough water, ice or packed snow
on the road to make a ªmirrored surfaceº Ð and slow
down when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
4-17

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving (except when you are pushing on the
brake pedal ®rmly).
{CAUTION:
The brake wear warning sound means that
soon your brakes will not work well. That
could lead to an accident. When you hear the
brake wear warning sound, have your vehicle
serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are ®rst applied or lightly
applied. This does not mean something is wrong with
your brakes.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
As you make brake stops, your disc brakes
automatically adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system Ð for example, when your brake linings
wear down and you need new ones put in Ð be sure
you get new approved GM replacement parts. If you do
not, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change Ð for the worse. The braking
performance you have come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.

Run-Flat Tires
Your vehicle, when new, had run-¯at tires. There's no
spare tire, no tire changing equipment and no place
to store a tire in the vehicle. Run-¯at tires perform so
well without any air that a Tire Pressure Monitor
(TPM) is used to alert you if a tire has lost pressure.
If a tire goes ¯at, you won't need to stop on the side of
the road to change the tire. You can just keep on
driving. The shorter the distance you drive and the
slower the speed, the greater the chance that the tire will
not have to be replaced. If you drive on a de¯ated
run- ¯at tire for 50 miles (80 km) or less and at speeds
of 55 mph (90 km/h) or less, there is a good chance
that the tire can be repaired. The tire can operate
effectively with no air pressure for up to 200 miles
(320 km) at speeds up to 55 mph (90 km/h), but the tire
would then have to be replaced. When a tire is ®lled
with air, it provides a cushion between the road and the
wheel. Because you won't have this cushion when
driving on a de¯ated tire, try to avoid potholes that could
damage your wheel and require replacement of it.Some road hazards can damage a tire beyond repair.
This damage could occur even before you've driven
on the tire in a de¯ated condition. When a tire has been
damaged, or if you've driven any distance on a
run-¯at tire, check with an authorized run-¯at tire service
center to determine whether the tire can be repaired
or should be replaced. To maintain your vehicle's run-¯at
feature, all replacement tires must be self-supporting
tires. As soon as possible, contact the nearest
authorized GM or run-¯at servicing facility for inspection
and repair or replacement. To locate the nearest GM
or run-¯at servicing facility, call Roadside Assistance.
For phone numbers and Roadside Service details
see
Roadside Service on page 7-5.
{CAUTION:
Run-¯at tires are constructed differently than
other tires and could explode during improper
service. You or others could be injured or
killed if you attempt to repair, replace,
dismount, or mount a run-¯at tire. Let only an
authorized run-¯at service center repair,
replace, dismount and mount run-¯at tires.
