Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry. To
prevent this from happening, after
the inside of the vehicle has cooled,
turn the recirculation mode off.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be
re-selected when the engine is
turned on again.
This mode recirculates and helps to
quickly cool the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle.
The recirculation mode cannot be
used with floor, defrost, or defogging
modes. If recirculation is selected in these modes, the indicator flashes
three times and turns off. The air
conditioning also comes on when
this mode is activated unless the
outside air temperature is less than
4°C (40°F). While in recirculation
mode the windows can fog when
the weather is cold and damp. To
clear the fog, select either the defog
or defrost mode and increase the
fan speed.
REAR (Rear Climate Control):
Press to turn the rear heating and
air conditioning on or off. See
Rear
Climate Control System on page 8‑9
or Rear Climate Control System
(with Rear Seat Audio) on
page 8‑10.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(Rear Window Defogger):
Press to turn the rear window
defogger on or off. The rear window
defogger stays on for about
10 minutes, before automatically turning off. The defogger will also
turn off when the engine is
turned off.
Do not drive the vehicle until all
windows are clear.
For vehicles with heated outside
rearview mirrors, fog or frost is
cleared from the surface of the
mirror when
1is 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 the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal, or anything
similar to the defogger grid.

To use automatic mode:
1. Press the AUTO button.When AUTO is selected, the
current temperature(s) is
displayed and the AUTO
indicator light is on.
When AUTO is selected, the air
conditioning and air inlet are
automatically controlled. The air
conditioning runs when the
outside temperature is over 4°C
(40°F). The system is
automatically set to outside air,
unless it is hot outside and then
the air inlet changes to
recirculation mode to help
quickly cool the vehicle. The
recirculation indicator light will
come on. 2. Set the temperature for the
driver and passenger.
To find a comfortable setting,
start with a 22°C (73°F)
temperature setting and allow
about 20 minutes for the system
to regulate. Use the driver side
or passenger side temperature
control to adjust the temperature
setting as necessary. The
system will remain at the
selected setting. Choosing the
warmest or coolest temperatures
does not cause the vehicle to
heat or cool more quickly.
To avoid blowing cold air in cold
weather, the system delays
turning on the fan until warm air
is available. Turn the fan knob to
override this delay and select
the fan speed. Temperature Control
The driver and passenger side
temperature controls are used to
adjust the temperature of the air
coming through the system. The
temperature can be adjusted even if
the system is turned off since
outside air still enters the vehicle,
unless the recirculation mode is
selected. See
“Recirculation” later in
this section.

)(Bi-Level): Air is divided
between the instrument panel and
floor outlets. Some air is directed
towards the windshield and side
window outlets. Cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
6(Floor): Air is directed to the
floor outlets, with some of the air
directed to the windshield, side
window, and second row floor
outlets. In this mode, the system
uses outside air.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents.
When this mode is selected, the
system turns off recirculation and runs the air conditioning compressor
unless the outside temperature is
less than 4°C (40°F). Do not drive
the vehicle until all the windows are
clear.
0(Defrost):
Press to turn the
defrost on or off. This mode quickly
clears the windshield of fog or frost.
Air is directed to the windshield,

Climate Controls 8-7
turns off to show that the A/C mode
is not available. If the A/C is on and
the outside temperature drops
below a temperature which is too
cool for air conditioning to be
effective, the A/C indicator turns off
to show that the A/C mode has
been canceled.
On hot days, open the windows
briefly to let hot inside air escape.
This helps reduce the time it takes
for the interior of the vehicle to
cool down.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be
re-selected when the engine is

quickly cool the air inside the
vehicle. It can be used to prevent
outside air and odors from entering
the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrosting
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. The air
conditioning compressor also comes

Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
can block the flow of air into the
vehicle.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
.Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
.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.

shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control on slippery
surfaces.
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use Roadside
Assistance. SeeRoadside
Assistance Program (Mexico) on
page 13‑7 orRoadside Assistance
Program (U.S. and Canada) on
page 13‑10. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems” in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑20.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.

Driving and Operating 9-17
after 15 seconds to prevent
cranking motor damage. To
prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch to
the ACC/ACCESSORY or
LOCK/OFF position.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you hold the key in START
for up to a maximum of
15 seconds. Wait at least 15 seconds between each try, to
allow the cranking motor to cool
down. When the engine starts,
let go of the key and accelerator.
If the vehicle starts briefly but
then stops again, repeat these
steps. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates.
Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Engine Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater
should be plugged in at least four
hours before starting. Some models
may have an internal thermostat in
the cord which will prevent engine
coolant heater operation at
temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The bundled cord
is located on the driver side of
the engine compartment,
between the engine air cleaner
and the windshield washer fluid
reservoir. See Engine
Compartment Overview on
page 10‑5.
