2-77 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light will come
on when you start your
engine and may stay on
for several seconds.
That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you're driving, your vehicle needs
service. If the regular brake system warning light isn't
on, you still have brakes, but you don't have anti
-lock
brakes. If the regular brake system warning light is
also on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section. Also see
ªSERVICE ABSº under ªDriver Information
Center (DIC) Messagesº in the Index.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Traction Control System (TCS) Light
This light should come on
briefly as you start the
engine. If the light doesn't
come on then, have it fixed
so it will be ready to warn
you if there's a problem.
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYSTEM message when you're
driving, there's a problem with your TCS system and
your vehicle needs service. When this light is on, the
system will not limit wheel spin. Adjust your driving
accordingly. If the driver turns off the Traction Control
System by pressing the button on the console, the
TCS system light will come on and the TRACTION
SYSTEM OFF message will show on the DIC.

the system repaired as soon as possible. Adjust your
driving accordingly.SERVICE COLUMN LOCK: If the system that
controls the locking and unlocking of the steering
column does not work properly, have the vehicle towed
to a dealer for service.
PULL KEY
- WAIT 10 SEC: If this message comes
on, the steering column lock system has detected a
problem while engaging the steering column lock. This
message may occur when the ignition key is removed
and reinserted before the steering column lock system
fully locks or unlocks the steering column. To
acknowledge that you have read this message, and to
clear it from the display, remove the ignition key and
wait 10 seconds before reinserting the key into the

Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic.
This is a mistake. Your brakes may not have time
to cool between hard stops. Your brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary
braking. That means better braking and longer
brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and the
brake pedal will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with
the anti
-lock brake system,
this warning light will stay
on. See ªAnti
-Lock Brake
System Warning Lightº
in the Index.

Active Handling System (Option)
The optional Active Handling System is a computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively
applying any one of the vehicle's brakes.
When you first start your vehicle and begin to drive
away (6 mph (10 km/h)), the message ACT HNDLG
WARMING UP may be displayed in the DIC, the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The Active
Handling System performance is affected until the
message, WARM UP COMPLETE, is displayed
in the DIC.
In cold weather, the ACT HNDLG WARMING UP
message may continue up to 12 mph (20 km/h).
The Active Handling System is off until the WARM
UP COMPLETE message is displayed.
The ACTIVE HANDLING message will come on when
the system is operating. See ªDriver Information Center
Messagesº in the Index for more information. You may
also feel or hear the system working. This is normal.
The SERVICE ACTIVE
HNDLG message will be
displayed, the instrument
cluster light will come on,
and a chime will sound to
let you know if there is a
problem with the system.
See ªDriver Information
Center Messagesº in the
Index for more information.
When this light and the SERVICE ACTIVE HNDLG
message are on, the system is not operational. Adjust
your driving accordingly.
The Active Handling System comes on automatically
whenever you start your vehicle. To help maintain
directional control of the vehicle, you should always
leave the system on. You can turn the system off if you
ever need to. If you turn the Active Handling System
off, the Traction Control System will also be turned off.
Adjust your driving accordingly.
To turn the system off, press the ACTIVE HANDLING
button on the console. You can turn the system on and off
at any time by pressing the button. The DIC will display
the appropriate message when you push the button.
4-12 Competitive Driving Mode
The driver can select the optional handling mode by
pressing the ACTIVE HANDLING button on the
console for more than five seconds, while the vehicle
is stopped with the ignition on. Competitive Driving
mode allows the driver to have full control of the rear
wheels while the Active Handling System helps steer the
vehicle by selective brake application. The instrument
cluster light will not be on. The Traction Control System
will not be operating. Adjust your driving accordingly.
When you press the ACTIVE HANDLING button
again, or turn the ignition to ACC, the Active
Handling and Traction Control Systems will be on.
The TRAC/ACT HNDLG
-ON message will be
displayed temporarily in the DIC and a chime
will be heard.
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.
4-20
Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can't, try to slow down before you hit them.
CAUTION:
Wet brakes can cause accidents. They won't work
as well in a quick stop and may cause pulling to
one side. You could lose control of the vehicle.
After driving through a large puddle of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you're
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory plug. Turn off all lamps that
aren't needed as well as radios. This will avoid
sparks and help save both batteries. In addition,
it could save your radio.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (
-) terminals on each.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
