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 365and
StabiliTrak
®System on page 367.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 412.
Braking
SeeBrake System Warning Light on page 226.
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.
362
ProCarManuals.com

Remember: ABS 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 ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly 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
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle has a traction control system that
limits wheel spin. This is especially useful in
slippery road conditions. The system operates if it
senses that one or both of the front wheels are
spinning or beginning to lose traction. When
this happens, the system brakes the spinning
wheel(s) and/or reduces engine power to
limit wheel spin.
The TRACTION CONTROL ACTIVE message will
come on in the Driver Information Center (DIC)
when the traction control system is limiting wheel
spin. You may feel or hear the system working,
but this is normal.
365
ProCarManuals.com

If your vehicle is in cruise control when the traction
control 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.
This warning light will
come on to let you
know if there is
a problem with your
traction control system.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
If the SERVICE TRACTION SYSTEM message in
the DIC comes on and stays on or comes on
while you are driving, there’s a problem with your
traction control system. Have the traction
control system serviced by your Saturn retailer as
soon as possible.
When this warning message is on, the TRACTION
CONTROL OFF message in the DIC will come
on to remind you that the system will not limit
wheel spin. Adjust your driving accordingly.The traction control system automatically comes
on whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. But you
can turn the traction control system off if you ever
need to. You should turn the system off if your
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 391andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 390.
To turn the system off,
press the traction
control button located
on the center of
the instrument panel.
If the system is limiting wheel spin when you
press the button, the TRACTION CONTROL
ACTIVE message will go off, but the system will
not turn off until there is no longer a current
need to limit wheel spin. The TRACTION
CONTROL OFF message will come on to remind
you the system is off.
366
ProCarManuals.com

You can turn the system back on at any time by
pressing the button again. The traction control
system warning message should go off.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 412for more information.
StabiliTrak®System
Your vehicle is equipped with StabiliTrak®which
combines anti-lock brake, traction and stability
control systems and helps the driver maintain
directional control of the vehicle in most driving
conditions.
When you rst start your vehicle and begin to
drive away, the system performs several diagnostic
checks to insure there are no problems. You
may hear or feel the system working. This
is normal and does not mean there is a problem
with your vehicle.
If the system fails to turn on or activate, the
SERVICE STABILITY SYSTEM message will be
displayed on the Driver Information Center (DIC).If the vehicle has gone through heavy acceleration
or braking or multiple turns during the rst two miles
of driving after starting your vehicle, the STABILITY
CONTROL OFF message may appear on the DIC.
If this is the case, your vehicle does not need
servicing. You will need to turn the vehicle off and
then restart it to initialize StabiliTrak
®. If either
message appears on the DIC, and your vehicle has
not gone through hard acceleration, braking or
multiple turns in the rst two miles of driving, your
vehicle should be taken in for service.
The STABILITY CONTROL ACTIVE message will
appear on the DIC only when the system is
both on and activated. It means that an advanced
computer-controlled system has come on to
help your vehicle continue to go in the direction in
which you are steering. StabiliTrak
®activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of
ice or other slippery spot on the road. When
the system activates, you may hear a noise or feel
a vibration in the brake pedal. This is normal.
367
ProCarManuals.com

When the STABILITY CONTROL ACTIVE
message is on, you should continue to steer in the
direction you want to go. The system is designed
to help you in bad weather or other difficult driving
situations by making the most of whatever road
conditions will permit. For more information on the
stability messages, seeDriver Information
Center (DIC) on page 234.
If the StabiliTrak
®system turns off, the traction
control system warning light will illuminate, and
the STABILITY CONTROL OFF message
will appear on the DIC to warn the driver that
StabiliTrak
®is no longer available to assist you
with directional control of the vehicle. Adjust
your driving accordingly.
To realize the full benets of the stability
enhancement system, you should normally leave
StabiliTrak
®on, but it may be necessary to
turn the system off if your vehicle is stuck in sand,
mud, ice or snow, and you want to “rock” your
vehicle to attempt to free it. SeeRocking
Your Vehicle to Get It Out on page 391and
If Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 390.
Traction Control Operation
The traction control system is part of the
StabiliTrak®system. Traction control limits wheel
spin by reducing engine power to the wheels
(engine speed management) and by applying
brakes.
The traction control system is enabled
automatically when you start your vehicle. It will
activate and display the TRACTION CONTROL
ACTIVE message in the DIC if it senses that
one or both of the front wheels are spinning or
beginning to lose traction while driving.
If the brake traction-control system activates
constantly or if the brakes have heated up due
to high-speed braking, brake traction-control will be
disabled and the TRACTION CONTROL ACTIVE
message will be displayed. In the limited mode,
the traction control system will only use engine
traction-control and is limited in its ability to provide
optimal performance since the system will not
utilize brake traction-control to control slip on the
drive wheels. The system will return to normal
operation after the brakes have cooled. This can
take up to two minutes or longer depending
on brake usage.
368
ProCarManuals.com

The traction control system may activate on
dry or rough roads or under conditions such as
heavy acceleration while turning or abrupt
upshifts/downshifts of the transaxle. When this
happens you may notice a reduction in
acceleration, or may hear a noise or vibration.
This is normal.
If your vehicle is in cruise control when the system
activates, the STABILITY CONTROL ACTIVE
message will appear on the DIC and the cruise
control will automatically disengage. When
road conditions allow you to use cruise again,
you may re-engage the cruise control. SeeCruise
Control on page 188.
StabiliTrak
®may also turn off automatically if it
determines that a problem exists with the system.
If the problem does not clear itself after restarting
the vehicle, you should see your retailer for
service.
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.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” 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.
369
ProCarManuals.com

Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. 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 are 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. SeeTraction Control System
(TCS) on page 365andStabiliTrak
®System
on page 367.
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 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 “drive”
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.

vehicle’s performance. SeeAccessories and
Modications on page 412.

Loss of Control
Let us review what driving experts say
about what happens when the three control
systems — brakes, steering, and
acceleration — do not have enough friction
where the tires meet the road to do what the
driver has asked.
In any emergency, do not give up. Keep trying to
steer and constantly seek an escape route or
area of less danger.
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 overdriving 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 traction
control 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.
