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).
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not 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 excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
If your vehicle has the Traction Control System (TCS)
and the cruise control is on, TCS will begin to limit wheel
spin and the cruise control automatically turns off.
SeeTraction Control System (TCS) on page 4-5. When
road conditions allow you to safely use it again, the
cruise control can be turned back on.The cruise control buttons
are located on outboard
side of the steering wheel.
T(On/Off):Press this button to turn cruise control
on and off. The indicator is lit when cruise control is on.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET–:Press this button to set the speed or make the
vehicle decelerate.
[(Cancel):Press this button to cancel cruise control.
3-12

Setting Cruise Control
Cruise control will not work if the parking brake is set, or
if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to
the desired speed. SeeInstrument Panel Cluster on
page 3-33.
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Press the cruise control on/off button.
2. Get up to the desired speed.
3. Press and release the SET– button located on the
steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
If cruise control is set at a desired speed and the
brakes are applied, this shuts off the cruise control.
However, it does not need to be reset.
Once your vehicle reaches a speed of about 25 mph
(40 km/h) or more, press the +RES button on the
steering wheel. The vehicle goes back to the previously
selected speed and stays there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until you reach your new desired speed,
then release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle will go about 1 mph (1.6 km/h) faster.
3-13

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 you reach the desired lower speed,
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 will go 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. Many drivers
nd this to be too much trouble and do not use
cruise control on steep hills.
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.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the left
of the steering wheel.

Security Light
For information regarding
this light and the vehicle’s
security system, see
Content Theft-Deterrent on
page 2-17.
Fog Lamp Light
The fog lamp light will
come on when the fog
lamps are in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-17for more information.
Cruise Control Light
This light comes on
whenever you set the
cruise control.
The light goes out when the cruise control is turned off.
SeeCruise Control on page 3-12for more information.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-9
for more information.

ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
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 the 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 antilock work for you. You might hear
the antilock pump or motor operate, and feel the
brake pedal pulsate, 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 only if it senses
that the front wheels are spinning too much or beginning
to lose traction. When this happens, the system works
the front brakes and reduces engine power (by
closing the throttle and managing engine spark) to limit
wheel spin.
The traction control system and StabiliTrak
®warning
light will ash when the traction control system is limiting
wheel spin. SeeTraction Control System (TCS)
Warning Light on page 3-40for more information. 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
re-engage the cruise control. SeeCruise Control
on page 3-12for more information.
The SERVICE TRACTION CONTROL message, the
traction control system warning light and the StabiliTrak
®
warning light will come on to let you know if there is a
problem with the traction control system. SeeDIC
Warnings and Messages on page 3-56.
