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. SeeTraction
Control System (TCS) on page 294.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 341.
Braking
SeeBrake System Warning Light on page 186.
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.
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. The brakes may not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking.
290

Page 291 of 512

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 vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 341.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will
come on briey
when you start your
vehicle.
When you start your engine, or when you begin to
drive away, your ABS 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 or pulses a
little. This is normal.

Traction Control System (TCS)
Your vehicle may have a Traction Control System
(TCS) that limits wheel spin. This is especially
useful in slippery road conditions. The system
operates only if it senses that one or both of the
front wheels are spinning or beginning to lose
traction. When this happens, the system works the
front brakes and reduces engine power to limit
wheel spin. It may also upshift the transaxle to limit
wheel spin. You may feel or hear the system
working, but this is normal.
The TRACTION CONTROL ACTIVE message on
the Driver Information Center (DIC) will be
displayed when the system is limiting wheel spin.
If the vehicle is in cruise control when the TCS
begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions
allow safe use of the cruise control, it can be used
again. SeeCruise Control on page 154.The TCS operates in all transaxle shift lever
positions. But the system can upshift the transaxle
only as high as the shift lever position that was
chosen, so use the lower gears only when
necessary. SeeAutomatic Transaxle Operation
on page 114.
This light, along with the
TRACTION CONTROL
OFF message, will
display on the DIC for
three seconds when the
TCS is not on.
If there is a problem with the system, the
SERVICE TRACTION SYSTEM message will also
come on in the DIC. When this warning light is
on, the system will not limit wheel spin. Adjust
driving accordingly.
294

Page 295 of 512

To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on.
But you can turn the system off if you ever
need to. The TCS should be turned off if the
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 319andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 318.
To turn the TCS on or off, press the TCS button
located above the radio.
When the TCS is turned off, the TCS warning light
will come on along with the TRACTION CONTROL
OFF message on the DIC. It will disappear when
the TCS is turned back on. If the TCS is limiting
wheel spin when the TCS button is pressed, the
TCS warning light will come on and the TCS will
turn off right away.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 341for more information.Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions. The
system operates only if it senses that one or
both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
reduces engine power and may also upshift
the transaxle to limit wheel spin. You may feel or
hear the system working, but this is normal.
The TRACTION CONTROL ACTIVE message on
the Driver Information Center (DIC) will be
displayed when the system is limiting wheel spin.
If the vehicle is in cruise control when ETS
begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions
allow safe use of it, the cruise control can be used
again. SeeCruise Control on page 154.
295

Page 296 of 512

The ETS operates in all transaxle shift lever
positions. But the system can upshift the transaxle
only as high as the chosen shift lever position,
so use the lower gears only when necessary. See
Automatic Transaxle Operation on page 114.
This light, along with the
TRACTION CONTROL
OFF message, will
display on the DIC for
three seconds when the
ETS is not on.
If there is a problem with the system, the
SERVICE TRACTION SYSTEM message will also
come on in the DIC. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the ETS on.
But you can turn the system off if you ever
need to. The ETS should be turned off if the
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required.To turn the ETS on or off, press the ETS button
located above the radio.
When the ETS is turned off, the ETS warning light
will come on along with the TRACTION
CONTROL OFF message on the DIC. It will
disappear when the ETS is turned back on. If the
ETS is limiting wheel spin when the traction
control button is pressed, the ETS warning light
will come on and the ETS will turn off right away.
StabiliTrak®System
Your vehicle may be equipped with a vehicle
stability enhancement system called StabiliTrak®.
It is an advanced computer controlled system
that assists you with directional control of
the vehicle in difficult driving conditions.
StabiliTrak
®activates when the computer senses
a discrepancy between your intended path
and the direction the vehicle is actually traveling.
StabiliTrak
®selectively applies braking pressure
at any one of the vehicle’s brakes to help steer the
vehicle in the direction which you are steering.
