Climate Controls
Dual Climate Control System
Your vehicle may have a dual climate control system.
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs the remaining
air to the oor outlets. Cooler air is directed to the upper
outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets. Use this mode to send air to the rear of
the vehicle. Keep the area under the front seats free of
objects that could obstruct airow to the rear of the
vehicle.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging
and Defrosting” later in this section.
3-25

Outside Air:This mode will be automatically selected
when your vehicle is in any mode except maximum
air conditioning.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. Turn the knob to 0 to turn off the fan. The fan
must be turned on for the air conditioning compressor
to operate.
Temperature Control:Use the driver’s and
passenger’s levers to increase or decrease the air
temperature inside your vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When it is pressed, an
indicator light in the button will come on to let you
know that air conditioning is activated.
You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
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.
#MAX (Maximum Air Conditioning):Turn the
right knob to this position for maximum air conditioning.
This will select air conditioning and recirculation for
maximum cooling of your vehicle.
Recirculation:This mode keeps outside air from
coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or help heat
or cool the air inside your vehicle more quickly.
This mode will automatically be selected when you
select maximum air conditioning.
3-26

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. An indicator
light in the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off about 10 minutes
after the button is pressed. If turned on again, the
defogger will only run for about ve minutes before
turning off. The defogger can also be turned off
by pressing the button again or by turning off
the engine.
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
k(Open):Turn the thumbwheel to this position to
open the air outlets.
l(Closed):Turn the thumbwheel to this position to
close the air outlets.
Use the louvers located on the air outlets to change the
direction of the airow.
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.
Use of non-GM approved hood deectors may
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.

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeAnti-Lock Brake
System Warning Light on page 3-38andTowing Your
Vehicle on page 4-37.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning
light on can lead to an accident. If the light
is still on after you have pulled off the road
and stopped carefully, have the vehicle towed
for service.
Anti-Lock Brake System Warning
Light
Your vehicle may have
this light. If it does, the
anti-lock brake system
warning light should come
on for a few seconds
when you turn the ignition
key to RUN.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on again
while you’re driving, the anti-lock brake system needs
service and you don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briey when you turn the ignition key to RUN. If
the light doesn’t come on then, have it xed so it will be
ready to warn you if there is a problem.

Time Elapsed
Press the information button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you can
clock the time it takes to get from one point to another.
Each of the elds for the hours, minutes, and seconds
are two numeric digits.
Once TIME ELAPSED :00 is displayed, press the
set/reset button to start the timing feature. Press the
set/reset button again to stop it. If you will be starting
and stopping your vehicle, during a trip for instance, the
TIME ELAPSED feature will automatically start timing
where it left off when you last stopped. To reset it,
press and hold the set/reset button for approximately
1.5 seconds. The display will return to zero.
Average Speed
Press the information button until AVERAGE SPEED
displays. This mode shows the average speed of
the vehicle in miles per hour (mph) or kilometers
per hour (km/h). This average is calculated based on
the various vehicle speed recorded since the last reset
of this value. To reset the value, press the information
button to display AVERAGE SPEED, then press
and hold the set/reset button. The display will return
to zero.
Fuel Range
Press the information button until FUEL RANGE
displays. This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance travelled, fuel used, fuel capacity, etc. This
estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode may read one number, but if the vehicle
is driven on a freeway, the number may change even
though the same amount of fuel is in the fuel tank.
This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See
“LOW FUEL” underDIC Warnings and Messages on
page 3-51for more information.
