Selective Real Time Damping
(SRTD) (Option)
You may have a ride control system on your vehicle
called Selective Real Time Damping (SRTD). The
system provides the following performance benefits:

Reduced Impact Harshness

Improved Road Isolation

Improved High
-Speed Stability

Improved Handling Response
This switch is on the center console. Turn it to select the
suspension characteristic of your choice.
TOUR: Use for normal city and highway driving. This
setting provides a smooth, soft ride.
SPORT: Use where road conditions or personal
preference demand more control. This setting provides
more ªfeel,º or response to the road conditions.
PERF: Use for performance driving. This setting
provides a tight, firm ride and precise response to
road conditions.
You can select a setting at any time. Based on road
conditions, steering wheel angle and your vehicle speed,
the system automatically adjusts to provide the best ride
and handling. Select a new setting whenever driving
conditions change.
There are three Driver Information Center (DIC)
messages that are displayed when a malfunction occurs
with the SRTD system. Refer to ªDIC Warnings and
Messagesº in the Index.

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 about
25 mph (40 km/h).
When using cruise control, the accelerator pedal will
return to its fully
-released position and will not move
while cruise control is engaged.The Driver Information Center (DIC) will display the
cruise set speed in a digital number. For example, the
DIC will say CRUISE SET 60 mph (97 km/h). When
you apply the brakes or push the clutch pedal, the cruise
control disengages. The DIC will show CRUISE
DISENGAGED. See ªDIC Warnings and Messagesº in
the Index.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't 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 needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.

To adjust the HUD so you can see it properly:
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
the ambient light conditions in the direction your
vehicle is facing and where you have the HUD
dimmer control 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.
2. Adjust the seat to your driving position. If you
change your seat position later, you may have to
re
-adjust your HUD.
3. Press the DISPLAY rocker switch up or down to
center the HUD image in your view.
NOTE: The HUD image can only be adjusted up and
down, not side
-to-side.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn HUD
off, slide the switch to OFF.
If the sun comes out or it becomes cloudy, you may need
to adjust the HUD brightness again using the dimmer
control. Polarized sunglasses could make the HUD
image harder to see.To change from English to metric units, push the E/M
button located to the right of the steering wheel.
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 the ignition is on and you can't see the HUD image,
check to see if:

something is covering the HUD unit.

the HUD dimmer control is adjusted properly.

the HUD image is adjusted to the proper height.

ambient light (in the direction your vehicle is facing)
is low.

a fuse is blown. See ªFuses and Circuit Breakersº in
the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred and out of focus.

Here's how anti-lock works. Let's say the road is wet.
You're driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes. 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.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

yellowblue
4-9
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 hear a
motor or clicking noise and feel the brake pedal move a
little during a stop, but this is normal.
Traction Control System (TCS)
Your vehicle has a traction control system called TCS
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark) to
limit wheel spin.The TRACTION SYSTEM ACTIVE message will
come on when the TCS system is limiting wheel spin.
See ªTRACTION SYSTEM ACTIVE Messageº in the
Index. You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the TCS system
begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions allow
you to safely use it again, you may re
-engage the cruise
control. (See ªCruise Controlº in the Index.)
The SERVICE TRACTION
SYSTEM message and the
TCS warning light will
come on to let you know if
there's a problem with your
TCS system. See
ªSERVICE TRACTION
SYSTEM Messageº in
the Index.

4-12 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
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.
Magnasteer

Your vehicle is equipped with GM Magnasteer, a
steering system that continuously adjusts the effort you
feel when steering at all vehicle speeds. It provides ease
when parking yet a firm, solid feel at highway speeds.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº 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 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. Refer to ªTraction
Control Systemº in the Index.
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'll want to go slower.
