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 you apply your brakes, the cruise control shuts off.
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.
If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin, the
cruise control will automatically disengage. See
ªTraction Control Systemº in the Index. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
Setting Cruise Control
CAUTION:
If you leave your cruise control switch 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.

2-79 Traction Control System Warning
Light (Option)
This warning light should
come on briefly when the
engine is started.
If the warning 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 when you're driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the button
located on the end of the shift lever, the warning
light will come on and stay on. To turn the system
back on, press the button again. The warning light
should go off. See ªTraction Control Systemº in the
Index for more information.
If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off, the warning light will come on and the
chime will sound.
If the traction control system is affected by an
engine
-related problem, the system will turn
off, the warning light will come on and the
chime will sound.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

- 54: If you ever
see the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem. You
should see your dealer for service. Reduce your speed
and drive accordingly.
STABILITY SYSTEM ACTIVE
- 55: You may see
the STABILITY SYSTEM ACTIVE message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system 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 is on,
you may hear a noise or feel a vibration in the brake
pedal. This is normal.

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're driving on snow or ice, it's easy
to ask more of those control systems than the tires and road
can provide. That means you can lose control of your vehicle.
Also see ªTraction Control Systemº in the Index.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's perception time. Then you have to bring up your
foot and do it. That's reaction time.
Average reaction time is about 3/4 of a second. But
that's 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 3/4 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's pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.
Page 205 of 392
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 feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
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.
Traction Control System
(If Equipped)
Your vehicle may have a traction control system 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.
You may feel or hear the system working, but this
is normal.
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
reengage the cruise control. See ªCruise Controlº
in the Index.
Page 206 of 392
4-10
This light should come on
briefly when you start the
engine. If it stays on or
comes on while you are
driving, there's a problem
with your traction
control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is on, 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. See ªRocking Your Vehicleº in the Index.
To turn the system off, press the button located at the
end of the shift lever.
The traction control system warning light will come on
and stay on. If the system is limiting wheel spin when
you press the button, the warning light will come
on
-- but the system won't turn off right away.
It will wait until there's no longer a current need to
limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The traction control system warning
light should go off.

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.
Magnetic-Speed Variable Assist Steering
(If Equipped)
Your vehicle may be equipped with this 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 Controlº 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.
If you have Stabilitrak
, you may see the STABILITY
SYSTEM ACTIVE message on the Driver Information
Center. See ªStability System Active Messageº in
the Index.
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.

Loss of Control
Let's review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don't have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don't 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 ªoverdrivingº
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
aren't 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.
If you have the traction control system, remember:
It helps avoid only the acceleration skid.
If you do not have traction control, or if the 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.
If you have Stabilitrak
, you may see the STABILITY
SYSTEM ACTIVE message on the Driver Information
Center. See ªStability System Active Messageº in the Index.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you'll
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.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration or braking
(including engine braking by shifting to a lower gear).
Any sudden changes could cause the tires to slide. You may
not realize the surface is slippery until your vehicle is
skidding. Learn to recognize warning clues
-- such as
enough water, ice or packed snow on the road to make a
ªmirrored surfaceº
-- and slow down when you
have any doubt.
Remember: Any anti
-lock brake system (ABS) helps
avoid only the braking skid.
