Windshield Washer
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
J(Washer Fluid):Press and release
this paddle, located at the top of the turn
signal/multifunction lever, to spray washer
uid on the windshield. The wipers will clear
the windshield and either stop or return to your
preset speed. For more washer cycles, press
and hold the paddle.
_(Heated Washer Fluid):The heated
windshield washer uid system, if your vehicle
has this feature, may be used to help clear
ice, snow, tree sap, or bugs from your windshield.Sliding the switch on the turn signal/multifunction
lever to this position and then releasing it will
activate the heated windshield washer uid
system. This activation will initiate four heated
wash/wipe cycles. The rst heated wash/wipe
cycle may take up to 40 seconds to occur,
depending on outside temperature. After the rst
wash/wipe cycle, it may take up to 20 seconds
for each of the remaining cycles. The heated
windshield washer uid system may be turned off
at any time by sliding the switch on the turn
signal/multifunction lever to this position again.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
WASHER FLUID LOW ADD FLUID will be
displayed on the Driver Information Center (DIC)
when the washer uid is low. SeeDIC Warnings
and Messages on page 246.

Approaching and Following a Vehicle
The Vehicle Ahead
symbol is located on the
top of the instrument
panel to the right of the
driver.
The Vehicle Ahead symbol will only appear when
a vehicle is detected in your path.
If this symbol does not appear, or disappears
briey, Adaptive Cruise Control will not respond to
vehicles you may see ahead.{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not
detect a vehicle ahead. Adaptive Cruise
Control may not have time to slow your
vehicle enough to avoid a collision. Do
not use Adaptive Cruise Control when
the radar is blocked by snow, ice, or dirt.
Keep your radar clean. See “Cleaning the
System” later in this section.
Adaptive Cruise Control will automatically slow
your vehicle down when approaching a slower
moving vehicle. It will then adjust your speed to
follow the vehicle in front at the selected follow
distance. Your speed will increase or decrease
to follow the vehicle in front of you but will
not exceed the set speed. It may apply limited
braking, if necessary. When braking is active,
your brake lights will come on. Braking may feel
or sound different than if you were applying
the brakes yourself. This is normal.
187

Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
speed, vehicle load, traffic conditions and the
steepness of the hills. It may not detect a vehicle
in your lane while driving on hills. When going up
steep hills, you may want to use the accelerator
pedal to maintain your vehicle’s speed. When going
downhill, especially when towing a trailer, you may
want to brake to keep your speed down. Applying
the brake disengages the system. You may choose
not to use Adaptive Cruise Control on steep hills,
especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
When you press the Adaptive Cruise Control
button or turn the ignition off, the set speed
memory is erased.
Other Messages
There are three additional messages that may
appear on the DIC. They are SERVICE RADAR
CRUISE, RADAR CRUISE NOT READY and
CLEAN RADAR. These messages will appear
to indicate a problem with the Adaptive Cruise
Control. SeeDIC Warnings and Messages
on page 246for more information.
Cleaning the System
The radar can become blocked by snow, ice, or
dirt. If so, you may need to turn off the engine and
clean the lens. Remember, do not use Adaptive
Cruise Control in icy conditions, or when visibility
is low, such as in fog, rain or snow.
The emblem/lens is located in the center of
the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to
engage the Adaptive Cruise Control. If you
are unable to do so, see your dealer.

The headlamp stalk is moved forward to the
high-beam position or the ash-to-pass feature
is used. SeeHeadlamp High/Low-Beam
Changer on page 167andFlash-to-Pass
on page 172.
When either of these conditions occur, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off until
the high-beam stalk is returned to the neutral
position.
If IntelliBeam™ was using low-beams prior
to this action, the IntelliBeam™ feature is
temporarily disabled until the stalk is returned
to the neutral position.
The exterior lamp control is turned to any
setting except AUTO.
When this occurs, IntelliBeam™ is disabled
until the control is turned back to the AUTO
position.
The IntelliBeam™ system is turned off at the
inside rearview mirror.IntelliBeam™ might not turn off the high-beams if
the system cannot detect other vehicle’s lamps
because of any of the following:
The other vehicle’s lamp(s) are missing,
damaged, obstructed from view, or otherwise
undetected.
The other vehicle’s lamp(s) are covered with
dirt, snow, and/or road spray.
The other vehicle’s lamp(s) cannot be detected
due to dense exhaust, smoke, fog, snow, road
spray, mist, or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view
of the IntelliBeam™ light sensor.
Your vehicle’s windshield is covered with ice,
dirt, haze, or other obstructions.
Your vehicle is loaded such that the front
end of the vehicle points upward, causing the
IntelliBeam™ sensor to aim high and not detect
headlamps and taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
195

Cornering Lamps
The cornering lamps come on when the
headlamps or parking lamps are on and you
signal a turn with the multifunction lever.
They provide more light for cornering.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have
been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is
turned to OFF. This protects against draining
the battery in case you have accidentally left the
headlamps or parking lamps on. The battery saver
does not work if the headlamps are turned on
after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to
turn the lamps back on.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The button for this control is located below the
exterior lamps control.
Push the button in and release to extend the button.
Turn the button clockwise for brightness of the
instrument panel lights and counter clockwise to
turn the brightness down.
Courtesy Lamps
The courtesy lamps are located on the headliner
above the rear seat. These lamps come on by
turning the instrument panel brightness knob fully
clockwise or when any door is opened and it is
dark outside. Puddle lamps are located on
the bottom of the front and rear door trim.
Professional vehicles have an additional dome
lamp and also opera lamps.
199

Entry Lighting
This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press
the remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the entry
lighting system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn
on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will
dim to off if the ignition key is turned to RUN, or
immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the digital
displays and backlighting during daylight hours
when the key is in the ignition and the headlamps
are on. This feature is fully automatic. When
the light sensor reads darkness outside and the
parking lamps are active, the digital displays
can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and
clockwise to brighten lighting.
Reading Lamps
The reading lamps are located on the overhead
console on the headliner and in the rear door
opening. These lamps come on automatically
when any door is opened and it is dark outside.
For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Battery Load Management
The battery load management feature is
designed to monitor the vehicle’s electrical
load and determine when the battery is in a
heavy discharge condition. During times of high
electrical loading, the engine may idle at a higher
revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.

Analog Clock
The analog clock is located on the instrument
panel above the radio. The clock is not connected
with any other vehicle system and runs by
itself. To adjust the clock, do the following:
1. Locate the adjustment button directly below
the clock face.
2. Push and hold the adjustment button to
advance the clock hands. Holding the
button down will cause the clock to advance
faster. Release the buttonbeforeyou get
to the desired time.
3. Push and release the button to increase the
time by one minute increments until the
desired time is reached.
Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
To avoid window fogging on rainy and humid
days at temperatures above freezing, run the
air conditioning compressor. Also, it is best
to avoid the use of recirculation mode except
when maximum air conditioning performance
is needed for a short amount of time to avoid
exterior odors and fogging.
Dual Climate Control System
210

After the vehicle is started, the display will
show the interior temperature settings and the
outside temperature.
If the AUTO position is selected on the fan or mode
control, the system will automatically control the air
conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator
light will be lit when the system is operating
automatically, even at near freezing outside
temperatures. Press the A/C button on the fan
control to turn off the A/C. For improved window
clearing performance in defog or defrost modes,
the A/C compressor will run automatically.
h(AUTO RECIRCULATION):If the AUTO
position is selected on either the fan or mode
control, the system will automatically control the air
inlet to supply fresh outside air or recirculate the
interior air to cool the car faster. The indicator light
on the recirculation button will light whenever the
system switches to recirculation. You may force
outside air by pressing the recirculation button
when the light is lit. For vehicles without rear climate
controls, press the outside air button to force
outside air. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO
operation.
Manual Operation
9(Fan):Turn the left control either to the left or
right to adjust the fan speed. Turning this control
completely counterclockwise will turn on the
automatic fan operation. Turning this control to the
“O” position will turn the climate control system off.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air
lter may need to be replaced. SeePassenger
Compartment Air Filter on page 220.
9(Off):Turn the left control to this position to
turn the entire climate control system off.
To change the current mode, select one of the
following positions using the right control:
AUTO:Turn the control to this position to turn on
the automatic delivery mode operation.
F(Vent):Turn the control to this mode to direct
air to the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to
direct approximately half of the air to the instrument
panel outlets and most of the remaining air to the
oor outlets. In automatic operation, cooler air is
directed to the upper outlets and warmer air to the
oor outlets.
212

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press the center of the right
control to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear
window as possible. The rear window defogger will
turn off approximately 20 minutes after the button is
pressed if your vehicle is moving at slower vehicle
speeds. At higher vehicle speeds, the rear defogger
may stay on continuously. Each additional press
will run the defogger for approximately 10 minutes.
The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the mirror
when the rear window defogger is on.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
For the front outlets, use the thumbwheel located
below each outlet to change the direction of the
airow. Use the thumbwheel located next to the
outlets to shut the airow or to open the outlets
and re-direct the air.
For the rear outlets, slide the lever left or right
and up or down to change the direction of
the airow.
Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors
may adversely affect the performance of
the system.
Keep the path under the front seats clear
of objects to help circulate the air inside
of your vehicle more effectively.
217

When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull
off the road and stop carefully. You may notice that
the pedal is harder to push, or the pedal may go
closer to the oor. It may take longer to stop.
If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 340.
{CAUTION:
Your brake system may not be working
properly if the brake system warning
light is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will
come on when your
engine is started
and may stay on for
several seconds.
That is normal.
If the ABS warning light comes on and stays on,
there may be a problem with the antilock portion
of the brake system. If the red BRAKE light is
not on, you still have brakes, but you do not have
antilock brakes. SeeBrake System Warning
Light on page 229.
If the light stays on, turn the ignition to OFF or
ACCESSORY. If the light comes on when you are
driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on
again while you are driving, your vehicle needs
service. If the regular brake system warning light
is not on, you still have brakes, but you do not
have anti-lock brakes.
