Cruise Control
The buttons for the cruise control are located on the
steering wheel.
I(Cruise On/Off):Push this button to turn the
system on and off.
RES + (Resume/Accelerate):Push this button to make
the vehicle resume a previously set speed or to
accelerate when cruise is already active.
SET−(Set/Decelerate):Push this button to set the
speed or to decrease the speed when cruise is already
active.With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained 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 the brakes are applied, the cruise control shuts off.
{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.
The cruise control will automatically disengage if the
vehicle has the traction control system and begins
to limit wheel spin. SeeTraction Control System (TCS)
on page 4-10. When road conditions allow, the cruise
control can be used again.
3-10

Setting Cruise Control
{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 on/off button. The indicator light in
the button will come on.
2. Get up to the speed you want.
3. Press the SET−button. The cruise symbol will
display in the instrument panel cluster when the
system is engaged.
4. Take your foot off the accelerator pedal.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This, of course,
disengages the cruise control. The cruise symbol in the
instrument panel cluster will go out, indicating cruise
control is no longer engaged.To return to your previously set speed, press the
RES + button once you are going about 25 mph
(40 km/h) or more.
You will go right back up to your chosen speed and
stay there.
If you hold the RES + button, the vehicle will keep going
faster until you release the button or apply the brake.
So unless you want to go faster, do not hold the RES +
button.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the SET−button, then release
the button and the accelerator pedal. You’ll now
cruise at the higher speed.
Press the RES + button. Hold it there until you get up
to the speed you want, and then release the button.
To increase your speed in very small amounts, press
the button briey. Each time you do this, your vehicle
will go about 1 mph (1.6 km/h) faster.
3-11

Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
Press the SET−button until you reach the lower
speed you want, then release it.
To slow down in very small amounts, briey press
the SET−button. Each time you do this, you will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle’s
speed. When you take your foot off the pedal, the
vehicle will slow down to the cruise control speed
you set earlier.
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the speed and load of the vehicle, and the
steepness of the hills. When going up steep hills, you
may have to step on the accelerator pedal to maintain the
vehicle’s speed. When going downhill, you may have to
brake or shift to a lower gear to keep the vehicle’s speed
down. Of course, applying the brake takes the vehicle out
of cruise control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
To end a cruise control session, step lightly on the
brake pedal.
Stepping on the brake will end the current cruise control
session only. Press the cruise on/off button to turn off
the system completely.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Security Light
For information
regarding this light,
seeTheft-Deterrent
Systems on page 2-18.
Cruise Control Light
This light comes on
whenever you set
your cruise control.
The light will go out when the cruise control is turned off.
SeeCruise Control on page 3-10for more information.
Reduced Engine Power Light
If the reduced engine
power light is on, a chime
will sound and a noticeable
reduction in the vehicle’s
performance may occur.
If the reduced engine power light is on, but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a reduced
speed while the reduced engine power light is on, but
acceleration and speed may be reduced.
Anytime the reduced engine power light stays on, the
vehicle should be taken to an authorized GM dealer
as soon as possible for service.

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 reduces engine power and may also upshift the
transaxle to limit wheel spin.
The traction control system
active light will come on
while the TCS is limiting
wheel spin.
If your vehicle has a Driver Information Center (DIC),
the TRACTION CONTROL ACTIVE message will
come on in the while the TCS is limiting wheel spin.
You may feel or hear the system working, but this
is normal.
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 3-10.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 2-26.
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 4-31
andIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-30.
To turn the TCS on or off, press the TCS button located
directly behind the gear shift lever. If your vehicle has
a DIC, the TCS button is located above the radio.
When the TCS is turned off, the TCS warning light
will come on. 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 5-3for more information.
