Climate Controls
Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system. If your vehicle has the
remote start feature, the climate control system functions
as part of the remote start feature. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5.
Operation
9
(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan runs continuously
with the ignition on. To turn off the air completely,
turn the fan to 0 and select the recirculation button.Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside the vehicle.
Use the right knob to select from the following modes:
There is one position between each mode to nely
adjust air ow position.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode splits the air between the
instrument panel outlets and the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the windshield
and side windows.
The right knob may also be used to select the defrost
and defog modes that are described in this section.
You can also select modes by using the following buttons:
;(Outside Air):Press this button to turn the
outside air mode on. When this mode is on, outside air
will circulate throughout the vehicle. When the button
is pressed, an indicator light in the button comes on
to show that it is activated. The outside air mode can
be used with all modes, but it cannot be used with
the recirculation mode.

Defogging and Defrosting
Fog or frost on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly.
Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield more
quickly. When either of these modes are selected, the
system runs the air conditioning compressor and cancels
the recirculation mode to dry the air. For best results,
clear all snow and ice from the windshield before
defrosting.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets, and half to
the oor outlets.
0(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with some
air directed to the oor outlets.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger only works when the ignition
is in ON/RUN.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light on the button
comes on to show that the rear window defogger is
activated.
The rear window defroster stays on for about 10
minutes if the vehicle remains at slower vehicle speeds
or until the button is pressed, or unless the ignition
is turned to ACC/ACCESSORY or LOCK/OFF. If turned
on again, the defogger only runs for about ve
minutes before turning off again. At higher vehicle
speeds, the defogger may stay on continuously. The
defogger can always be turned off by pressing the
button again or by turning off the ignition.
3-21
If your vehicle has the remote start feature, the rear
defogger automatically turns on if it is cold outside.
When the vehicle transitions out of the remote start
mode, the rear defogger will turn off. SeeRemote
Keyless Entry (RKE) System Operation on page 2-5.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would
not be covered by your warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
Remote Start Climate Control Operation
If your vehicle has the remote start feature and it
is activated, the climate control system heats and cools
the inside of the vehicle using the modes that were
set before the vehicle was turned off and the rear
defogger automatically turns on. If your vehicle has
heated seats, they may turn on if it is cold outside
and will shut off when the key is turned to ON/RUN.
SeeHeated Seats on page 1-4.
Outlet Adjustment
Use the louvers located on the air outlets to change
the direction of the air ow.
Operation Tips
Clear away any ice, snow, or leaves from the air
inlets at the base of the vehicle that may block
the ow of air into your vehicle.
Do not use any non-GM approved hood de ectors
that could 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.
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. Reductions in air ow, which may occur
more quickly in dusty areas, indicate that the lter needs
to be replaced early.
The lter should be replaced as part of routine scheduled
maintenance. SeeScheduled Maintenance on page 6-4
for when to replace the lter.

Compass Calibration
The compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle
in circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers,
or other industrial structures, if possible.
If CAL should ever appear in the DIC display,
the compass should be calibrated.
If the DIC display does not show a heading, for example,
N for North, or the heading does not change after
making turns, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic CB or cell phone antenna
mount, a magnetic emergency light, magnetic note
pad holder, or any other magnetic item. Turn off
the vehicle, move the magnetic item, then turn on
the vehicle and calibrate the compass.To calibrate the compass, use the following procedure:Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is located. See “Compass
Variance (Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the vehicle information button until
PRESS
VTO CALIBRATE COMPAS (Compass)
displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle in tight circles at
less than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION COMPLETE
for a few seconds when the calibration is
complete. The DIC display will then return to
the previous menu.

Driving with a Trailer
{CAUTION:
If you have the liftgate open and you pull a
trailer with your vehicle, carbon monoxide (CO)
could come into your vehicle. You cannot see
or smell CO. It can cause unconsciousness or
death. SeeEngine Exhaust on page 2-35.To
maximize your safety when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the liftgate closed.
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum air
because it only recirculates the air inside
your vehicle. SeeClimate Control System
on page 3-19.Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you will want to
get to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure the
brakes are working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
