Reducing Speed While Using Cruise
Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the steering
wheel until the desired lower speed is reached,
then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel briey.
Each time this is done, the vehicle goes about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle speed.
When you take your foot off the pedal, the vehicle
will slow down to the cruise speed you set earlier.
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load and the steepness of
the hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain your speed.
When going downhill, you might have to brake or shift
to a lower gear to keep your speed down. If the brakes
are applied the cruise control will turn off.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[button on the steering wheel.
Press theTbutton on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.

Charging System Light
This light comes on briey
when the ignition key is
turned to START, but the
engine is not running, as a
check to show it is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-56for
more information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking both
parts need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the engine is
started. If it does not come on then, have it xed so it
will be ready to warn if there is a problem.

When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
will stay on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means there is a brake problem.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the light comes on while driving, pull off the road and
stop carefully. The pedal can be harder to push, or the
pedal could go closer to the oor. It could take longer to
stop. Try turning off and restarting the vehicle one or two
times, if the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-23.
Antilock Brake System (ABS)
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when
the engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally
the indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the
light comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-38.

Braking
SeeBrake System Warning Light on page 3-38.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it 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
the 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 might not have time to cool
between hard stops. The brakes will wear out much
faster with a lot of heavy braking. Keeping pace with
the traffic and allowing realistic following distances
eliminates a lot of unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the vehicle is being driven,
brake normally but do not pump the brakes. If the brakes
are pumped, the pedal could get harder to push down.
If the engine stops, there will still be some power brake
assist but it will be used when the brake is applied. Once
the power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can
affect vehicle’ performance. SeeAccessories and
Modifications on page 5-3.

Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on, and it might even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with
ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 3-39.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the 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.ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The antilock pump or
motor operating might be heard and the brake pedal
might be felt to pulsate, but this is normal.
4-5

Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more than
even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of the
vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist feature
will automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.
StabiliTrak®System
The vehicle may have the StabiliTrak system which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional
control of the vehicle in most driving conditions. This
is accomplished by selectively applying any one of the
vehicle’s brakes and reducing engine power.
The StabiliTrak system comes on automatically whenever
the vehicle is started. The system cannot be turned off.
This light will ash when
the system is operating.
The STABILITRAK NOT READY message may be
displayed in the Driver Information Center (DIC) and the
Traction Control System (TCS)/StabiliTrak warning light
on the instrument panel cluster comes on after rst
driving the vehicle and exceeding 19 mph (30 km/h) for
30 seconds. The StabiliTrak system is off until the light
has turned off. This could take up to 15 minutes.
