Climate Controls 8-3
Air Delivery Mode Control:Turn
clockwise or counterclockwise to
change the direction of the airflow
inside the vehicle.
To change the current mode, select
one of the following:
H(Vent): Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
6(Floor): Air is directed to the
floor outlets, with some of the air
directed to the windshield and side
window outlets. In this mode, the
system automatically selects
outside air.
-(Defog): This mode clears the
windshield of fog or moisture. Air is
directed equally to the windshield
and the floor outlets. When defog is
selected, the system turns off
recirculation and runs the air
conditioning compressor unless the
outside temperature is below
4°C (40°F).
0(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield with some air to the side
window vents and the floor vents.
When defrost is selected, the
system automatically forces outside
air into the vehicle. The air
conditioning compressor will run
automatically in this setting, unless
the outside temperature is below
4°C (40°F).
#(Air Conditioning): Press to
turn the air conditioning system
on or off. An indicator light comes
on to show that it is on. The air
conditioning can be selected in any
mode as long as the fan is on and
the outside temperature is above
freezing. A flashing indicator light
indicates that the air conditioning
compressor is currently not
available.
On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time it takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
For quick cool down on hot days, do
the following:
1. Select the
Hmode.
2. Press the
#button.
3. Select the coolest temperature for both zones.
4. Select the highest
9speed.
5. When the coolest temperature is selected in the A/C mode, the
system automatically goes into
the recirculation mode to
improve cooling.
Using these settings together for
long periods of time may cause the
air inside the vehicle to become too
dry. To prevent this from happening,
after the air inside the vehicle has
cooled, turn the recirculation
mode off.

8-4 Climate Controls
The air conditioning system
removes moisture from the air, so a
small amount of water may drip
under the vehicle while idling or
after turning off the engine. This is
normal.
%(Outside Air):Press to turn
on outside air. An indicator light
comes on to show that it is on.
Outside air will circulate throughout
the vehicle.
/(Recirculation): Press to
turn on the recirculation mode. An
indicator light comes on to show
that it is on.
This mode helps to quickly heat or
cool the air inside the vehicle once
the temperature inside the vehicle is
equal to or better than the outside
temperature. It can be used to
prevent outside air and odors
from entering the vehicle. The
recirculation mode is not available in
outside air, floor, defog, or defrost
modes. If the button is selected
while in these modes, the indicator
flashes three times.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(Rear Window Defogger): The
rear window defogger turns off
automatically after it has been
activated for 10 minutes. It can be
turned off manually, by pressing the
button again or by turning the
ignition to the LOCK/OFF position.
The rear window defogger can be
turned on again for additional
window clearing. The length of
defogger operation will increase if
the vehicle is being driven. For vehicles with heated outside
rearview mirrors, the mirrors heat to
help clear fog or frost from the
surface of the mirror when the rear
window defog button is pressed.
See
Power Mirrors on page 2‑14.
Do not drive the vehicle until all the
windows are clear.
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.

Air Vents
Use the thumbwheel located below
or to the side of the outlet, to
change the direction of the air flow.
Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into the
vehicle.
.Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
.Keep the path under the front
seats clear of objects to help
circulate the air inside the
vehicle more effectively.
.If the airflow seems low when
the fan is at the highest setting,
the passenger compartment air
filter, if equipped, may need to
replaced. For more information,
seePassenger Compartment Air
Filter on page 8‑5 and
Maintenance Schedule on
page 11‑3.
.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.
Maintenance
Passenger Compartment
Air Filter
The vehicle has a passenger
compartment particulate air filter.
It is located in the engine
compartment, below the air inlet
grille on the passenger side.
The filter traps most of the pollen
from air entering the climate control
system. It needs to be changed
periodically to ensure system
performance. For information on
how often to change the passenger
compartment air filter, see
Maintenance Schedule on
page 11‑3.

Recommended Fuel
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.
Gasoline Specifications
(U.S. and Canada Only)
At a minimum, gasoline should
meet ASTM specification D 4814in the United States or CAN/
CGSB‐3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. See
Fuel Additives
on page 9‑38 for additional
information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test. See
Malfunction Indicator Lamp on
page 5‑16. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
Never use leaded gasoline or any
other fuel not recommended in the
previous text on fuel. Costly repairs
caused by use of improper fuel
would not be covered by the vehicle
warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.
