Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
You may also have an arrow in the outside mirror that
ashes when the turn signal is used. SeeOutside Power
Mirrors on page 2-37for more information.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane
change is complete. If you momentarily press and
release the lever, the turn signal will ash three times.
If the arrows ash very fast as you signal a turn or
a lane change, a signal bulb may be burned out and
other drivers will not see your turn signal. If a bulb
is burned out, replace it to help avoid an accident.
If the arrows do not go on at all when you signal a turn,
check the fuse. SeeFuses and Circuit Breakers on
page 5-105.

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.

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.

Sensors
The solar sensor, located in the defrost grille, in the
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the system
will not work properly.
There is also an interior temperature sensor located
next to the steering wheel that measures the
temperature of the air inside the vehicle.There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature
inside the vehicle. Any cover on the front of the vehicle
could cause a false temperature reading to display.
In order to prevent false temperature readings at startup,
the displayed temperature will not change until the
following occurs:
Vehicle speed is above 10 mph (16 km/h) for
ve minutes.
Vehicle speed is above 32 mph (51 km/h) for
two and a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the air
delivery mode. The system may also supply cooler
air to the side of the vehicle facing the sun. The
recirculation mode will also be used as needed to
maintain cool outlet temperatures.
3-28

Outlet Adjustment
Use the levers, located in the middle of the front outlets,
to change the direction of the airow. Use the
thumbwheel located between the outlets to turn them on
and off.
If your vehicle has rear seat outlets, adjust the direction of
the airow using the lever in the center of each outlet.
Operation Tips

Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that could
block the ow of air into your vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside the vehicle better.
Passenger Compartment Air Filter
Outside air is routed through a passenger compartment
air lter before entering the vehicle. This lter removes
certain particles from the air, including pollen and
dust particles. The lter should be replaced as part of
routine scheduled maintenance. SeeScheduled
Maintenance on page 6-4for when to replace the lter.
The access panel for the passenger compartment air
lter is located under the hood near the windshield,
on the passenger’s side of the vehicle.
