For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the outside air.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
6. Once the vehicle’s interior temperature is below the
outside temperature, select recirculation mode for
enhanced cooling.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become
too dry. To prevent this from happening, after the
air inside of your vehicle has cooled, turn the
recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount
of water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.Defogging and Defrosting
Fog on the inside of the 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. There are two modes to clear
fog or frost from your windshield. 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.
Turn the right knob clockwise to select the defog or
defrost mode. Do not drive the vehicle until all the
windows are clear.
-(Defog):This mode directs air equally to the
windshield and the oor outlets. When you select this
mode, the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is below 40°F (4°C). The recirculation mode cannot
be selected while in the defog mode.
0(Defrost):This mode directs a portion of the air
to the windshield and side window vents and some
to the oor vents. In this mode, the system will
automatically force outside air into your vehicle.
The recirculation mode cannot be selected while in
the defog mode. The air conditioning compressor will
run automatically in this setting, unless the outside
temperature is below 40°F (4°C).

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<:The rear window defogger will turn off automatically
after it has been activated. The duration the rear window
defogger is on will be longer if the vehicle is being driven.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
If your vehicle has heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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.
Outlet Adjustment
Use the thumbwheel located below or to the side of the
outlet, 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 windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood de ectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside your vehicle more
effectively.
If the air ow seems low when the fan is at the
highest setting, the passenger compartment
air lter, if equipped, may need to replaced. For
more information, seePassenger Compartment Air
Filter on page 3-23andScheduled Maintenance
on page 6-4.
If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn
on the air conditioner to reduce windshield fogging.
