Cruise Control
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
approximately
25 mph (40 km/h).
When you apply the brakes, the cruise control
shuts
off.
If your vehicle is in cruise control when the traction
control system on the
3800 Supercharged V6 engine or
the enhanced traction system on the 3100 V6 and
3800 V6 engine begins to limit wheel spin, the cruise
control will automatically disengage. See Traction
Control System (TCS) on page
4- 10 or Enhanced
Traction System (ETS) on page
4-1 1. When road
conditions allow you to safely use it again, you may
turn the cruise control back on.
Setting Cruise Control
Cruise control can be dangerous where
you can’t drive safely at a steady speed.
So, don’t use you’r 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
needless wheel spinning, and you could
lose control. Don’t use cruise control on
slippery roads.
I
If you leave your cruise control on when you’re
not using cruise, you might hit a button and go
into cruise when you don’t want to. You could
be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the

The HUD also shows the following lights when they are
lit on the instrument panel cluster:
Turn Signal Indicators
High-Beam Indicator Symbol
Low Fuel Symbol
The HUD will display CHECK GAGES when the
following items are lit on the instrument panel cluster:
Oil Warning Symbol
Coolant Temperature Symbol
Charging System Symbol
When the ignition key is turned to RUN, the entire HUD
image will come on. Then the Head-Up Display will
operate normally.
Notice: Although the HUD image appears to be
near the front
of the vehicle, do not use it as
a parking aid. The
HUD was not designed for that
purpose.
If you try to use it as such, you may
misjudge the distance and damage your vehicle.
When the HUD is on, the speedometer reading will be
displayed continually. The current radio station
or
CD track number will only be displayed for three
seconds after the radio or CD track status changes.
This will happen whenever one of the radio controls is
pressed, either on the radio itself or on the optional
steering wheel controls. To
adjust the HUD
so you can see it properly do the
following:
1. Adjust your seat, if necessary, to a comfortable
position.
2. Start the engine and adjust the HUD controls
located on the instrument panel, to the right
of
the steering wheel. Move the DIM thumbwheel up
or down to adjust brightness.

3. Press the top of the UP/DN switch until the HUD
image stops moving. Then press the bottom of the
switch until the image is as low as possible but
in full view.
4. Move the DIM thumbwheel down ur;til the HUD
image is no brighter than necessary. To turn the
HUD off, move the DIM thumbwheel all the
way down.
If the sun comes out, it becomes cloudy, or if you turn
on your headlamps, you may need
to adjust the
HUD brightness again. The HUD will automatically dim
when the headlamps change from the
DRL mode to
full intensity. Polarized sunglasses could make the
HUD
image harder to see.
Push the
ENG/MET button
on the trip calculator,
located above the audio
controls on the trip
computer (if equipped) on
the instrument panel,
to switch the
HUD display
between English to
metric.
Care of the HUD
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity
of the
HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the
HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If your vehicle is not equipped with the trip calculator,
you cannot change the display.

The Driver Information Center (DIC) gives you important
safety and maintenance facts. When you turn the
ignition on, all of the DIC lights illuminate for a few
seconds. After this, the DIC will begin working.
Functions
__ (Door Ajar): If one of the doors is ajar, this light
will appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system indicates that it’s time for an oil change. The
system predicts remaining oil life using data from length
of drives, coolant temperature, engine rpm and
vehicle speed. It alerts you to change the oil on a
schedule consistent with the vehicle’s driving conditions.
After changing the oil, the system must be reset. See
How to Reset the GM
Oil Life SystemTM under
Engine
Oil on page 5- 18.
e LOW: This light will come on when the ignition is
on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.
LOW TRAC (Low Traction): If your vehicle is equipped
with anti-lock brakes, this light will come on when the
enhanced traction system is limiting wheel spin. See Enhanced Traction System (ETS) on page 4-
I I or
Low Traction Light on page 3-30.
TRAC OFF (Traction Off): If your vehicle is equipped
with anti-lock brakes, this light lets you know that
the enhanced traction system has been disabled and
will not limit wheel spin. See Enhanced Traction System
Warning Light
on page 3-30 or Low Traction Light on
page 3-30.
TRAC (Traction): If the vehicle has anti-lock brakes
and the enhanced traction system, you will have a
disable button on the far right side of the DIC.
The enhanced traction system is automatically activated
when you turn the ignition on. This button will
activate/deactivate the system. If you need to disable
the system, such
as when you are stuck and are rocking
the vehicle back and forth, push this button. See If
You Are Stuck: in Sand, Mud, Ice or Snow on
page 4-32.

Let’s say the road is wet and you’re driving safely.
Suddenly, an animal jumps out in front
of you. You slam
on the brakes and continue braking. Here’s 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. 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.
4-8

Remember: Anti-lock doesn’t 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 won’t 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
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However,
if you don’t have anti-lock,
your first reaction
- to hit the brake pedal hard and
hold it down
- may be the wrong thing to do. Your
wheels can stop rolling. Once they do, the vehicle
can’t respond to your steering. Momentum will carry
it in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the
very
thing you were trying to avoid, or into traffic.
If you don’t have anti-lock, use a “squeeze’’ braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control.
If you do have
anti-lock, it’s different. See “Anti-Lock Brakes.”
In many emergencies, steering can help you more than
even the very best braking.

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.
Variable Effort Steering
If your vehicle has this steering system, the system
provides less steering effort for parking and when driving
at speeds below
20 mph (32 km/h). Steering effort will
increase at higher speeds for improved road feel.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s 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’s no traction, inertia will keep the
vehicle going in the same direction. If you’ve ever tried to
steer a vehicle on wet ice, you’ll 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’re
in a curve, speed is the one factor you can control.
Suppose you’re steering through a sharp curve. Then you
suddenly accelerate. Both control systems
- steering
and braking
- have to do their work where the tires meet
the road. Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand
too much of those
places. You can lose control.
The same thing can happen
if you’re 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. See Traction Control
System (TCS) on page
4- 10 or Enhanced Traction
System (ETS)
on page 4- I 1.
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’ll want to
go slower.
