Passenger's Side Temperature Lever
The lever on the right side of the climate control panel
is used to adjust the air temperature on the passenger's
side, independent of the temperature set by the driver.
Slide the lever upward to raise the temperature. Slide
the lever downward to lower the temperature.
This lever also adjusts the temperature to the rear
seat outlets.
Mode Knob
The knob on the right side of the control panel has
several settings to control the direction of airflow:
(Panel): Selecting panel mode will deliver air to
the instrument panel outlets.
(Bi-Level): Selecting bi-level mode will deliver
warmer air to the floor and cooler air to the instrument
panel outlets.
(Floor): Selecting floor mode will deliver air to
the floor outlets and some air to the defroster and side
window vents.
(Defog): Selecting defog will deliver air to the
floor, windshield outlets and side window vents.
(Defrost): Selecting this setting directs most of the
air through the defroster and side window vents. Some
of the air also goes to the floor ducts.
Mode Buttons
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle and for maximum air conditioning performance
in hot weather. Recirculation cannot be used in floor,
blend or defrost modes. An indicator on the button will
light up, flash three times and turn off when
recirculation is selected in these modes.
While in the recirculation mode the windows may fog
when the weather is cold and damp. To clear the fog,
select either the blend or defrost mode and increase the
fan speed.
(Air Conditioning): Press this button to turn the
air conditioning compressor on and off. The system will
cool and dehumidify the air inside the vehicle when the
air conditioning compressor is engaged.

3-7
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to limit odors entering your
vehicle and for maximum air conditioning performance
in hot weather. Press this button again to allow outside
air to enter the vehicle.
If you select recirculation while in defrost, defog or
floor, the light on the button will flash and go out to let
you know this is not allowed. This is to prevent fogging.
When the weather is cool or damp, operating the system
in recirculation for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
select either defog or FRONT defrost. Be sure A/C OFF
is not selected to allow the air conditioning compressor
to run automatically and help dehumidify the air.
(Air Conditioning): Press this button to turn the
air conditioning compressor on and off. When air
conditioning is selected or in AUTO mode, the system
will run the air conditioning automatically to cool and
dehumidify the air entering the vehicle. If you select
A/C OFF while in FRONT defrost, the A/C OFF text
will flash to let you know this is not allowed. This is to
prevent fogging.
FRONT (Defrost): Press this button to defrost the
windshield. The system will automatically control the
fan speed if you select defrost from AUTO. If the
outside temperature is 40
F (4
C) or warmer, your air
conditioning compressor will automatically run to help
dehumidify the air and dry the windshield.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If your vehicle has the manual system, for quick
cool
-down on very hot days, use the airflow from the
panel outlets, press recirculation and air conditioning
with the temperature control in the blue area. If this max
air conditioning setting is used for long periods of time,
the air in your vehicle may become too cold and dry.
For normal cooling on hot days, use air conditioning
without recirculation with the temperature control in the
blue area.

3-8
If your vehicle has the automatic system, in AUTO
mode the system will cool and dehumidify the air
inside the vehicle. Also while in AUTO mode, the
system will maximize its performance by using
recirculation as necessary.
On cool, but sunny days, with the manual system or
through manual operation of the automatic system,
use bi
-level to deliver warm air to the floor and cooler
air to the instrument panel outlets. To warm or cool
the air delivered, turn the temperature control to the
desired setting.
Heating
If you have the manual system, on cold days use floor
with the temperature lever in the red area. If you have
the automatic system, press AUTO and adjust the
temperature by turning the temperature knob clockwise
or counterclockwise. You may also adjust the automatic
system manually by pressing the MODE button and
selecting floor. Again, adjust the temperature by turning
the temperature knob clockwise or counterclockwise.
With either system, outside air will be heated and sent
through the floor outlets. The heater works best if you
keep the windows closed while using it.
Defogging and Defrosting
On cool, humid days, use defog to keep the windshield
and side windows clear. Use front defrost to remove fog
or ice from the windshield quickly in extremely humid
or cold conditions.
If your vehicle has the manual system, select defog and
adjust the fan speed to your comfort level. Turn the air
conditioning on to help dehumidify the air. Use front
defrost with the temperature toward the red area and the
fan control toward high.
If your vehicle has the automatic system and you select
FRONT defrost or defog from AUTO, the system will
control the fan speed. Adjust the temperature and fan
speed to your comfort level. After the windshield is
clear, adjust the temperature to your normal setting and
select the AUTO button and return to AUTO mode and
fan control.
For maximum front defrost performance under extreme
icing or frosting conditions, increase the temperature
setting to 90
F (32
C) and increase the fan speed
to high.

3-9 Rear Window Defogger
The lines you see on the rear window warm the glass.
Press the button to start warming your window. A light
will glow in the button while the defogger is working.
If your vehicle is equipped with heated mirrors, this
button will activate them.
After 10 minutes it will turn off by itself, or press the
button during the heating cycle to turn it off. If you need
additional warming time, push the button again.Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the defogger grid. The repairs wouldn't be
covered by your warranty.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.

In cool damp weather, minimize your use of
recirculation to reduce the chance of fogging
your windows.

When you enter a vehicle with the standard system
in cold weather, select floor mode to supply air
through the floor outlets. Then turn the fan on high
for a few moments before driving away. This will
blow moist air from the intake outlets toward the
floor, not the windshield. It reduces the chance of
fogging your windows. If you have the electronic
system, the AUTO setting will do this for you.
Manual operation of the electronic system in the
floor mode will also supply air through the
floor outlets.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.Comfort Control Steering Wheel Controls
(If Equipped)
If your vehicle has this
feature, you can control
certain comfort control
functions using the buttons
on your steering wheel.
(Fan): Press the up arrow to increase the fan speed
and the down arrow to decrease the fan speed.
(Temperature): Press the up arrow to increase the
temperature of the air flowing through the system and
the down arrow to decrease the temperature of the air
flowing through the system.

3-51 Remote Control
To use the remote control, aim it at the small square
window to the left of the disc slot and press the desired
button. Direct sunlight or very bright light may affect
the ability of the entertainment system to receive signals
from the remote control. Be sure the remote's batteries
are not discharged, as this will also affect the function of
the remote control. Objects blocking the line of sight
may also affect the function of the remote control.
NOTICE:
Do not store the remote control in heat or direct
sunlight. This could damage the remote control
and would not be covered by your warranty.
Keep the remote control stored in a cool, dry place.
Remote Control Buttons
PWR (Power): Press this button to turn the DVD
player on or off.
PLAY/PAUSE: Press this button to play a disc.
Press this button while a disc is playing to pause. Press it
again to continue playing.

STOP: Press this button to stop playing, reversing or
fast forwarding the DVD.

3-63 Diversity Antenna System
Your AM FM antennas are located in the rear side
windows. Be sure that the inside surfaces of the rear side
windows are not scratched and that the lines on the glass
are not damaged. If the inside surfaces are damaged,
they could interfere with radio reception.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear side windows with a razor
blade or anything else that is sharp. This may
affect your radio's ability to pick up stations
clearly. The repairs wouldn't be covered by
your warranty.
If you choose to add an aftermarket cellular telephone
to your vehicle, and the antenna needs to be attached to
the glass, be sure that you do not damage the grid lines
for the AM FM antennas or place the cellular telephone
antenna over the grid lines.
Chime Level Adjustment
The volume level of the vehicle's chimes can be
controlled by the radio. To change the volume level,
press and hold pushbutton 6 with the ignition on
and the radio power off. The chime volume level will
change from the normal level to loud, and LOUD will
be displayed on the radio. To change back to the default
or normal setting, press and hold pushbutton 6 again.
The chime level will change from the loud level to
normal, and NORMAL will be displayed.

4-37
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in GMC
dealerships all across North America. They'll be ready
and willing to help if you need it.Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
