With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle has two accessory power outlets located on
the lower part of the instrument panel below the climate
control system and there may be one located in the rear
cargo area. A small cap must be pulled down to access
an accessory power outlet. When not using an outlet, be
sure to cover it with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.

Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and cigarette lighter.
Your ashtray is located in your center console area.
The ashtray can be removed for cleaning. When
the ashtray is removed, this area can also be used
as a cupholder.

Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation of your vehicle. In-between modes
are available by moving the right control knob between
modes with symbols. The in-between mode will be a
combination of the two modes that the control is
selected between.
Temperature:Turn the left knob on the control panel to
adjust the temperature of the air in the vehicle. Turn
the knob clockwise or counterclockwise to increase or
decrease the temperature.
#(Air Conditioning):Press the left knob on the
control panel to turn the air conditioning system on or
off. An indicator light on the button will come on to
let you know the air conditioning is activated. When the
system is on, this setting cools and dehumidies the
air entering your vehicle.
The air conditioning will not function if the fan is turned
off. If air conditioning is selected with fan off, the
indicator will ash three times and then turn off.
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.
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.
9(Fan):Turn the center knob on the control panel to
control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
3-21

9(Off):Turn the center knob to this position to turn
the fan off. With the fan off, you may still experience
airow from the system that increases with vehicle
speed depending on the mode and temperature settings.
Enable recirculation mode to stop this airow from
occurring.
The right knob on the control panel is used to direct the
airow inside your vehicle. Turn the knob to select
one of the following modes:
@(Recirculation):Press the center knob on the
control panel to recirculate air inside the vehicle
and prevent outside air from coming in. It can be used
to prevent outside odors from entering your vehicle
and cool the air inside your vehicle more quickly. Press
this button to turn the recirculation mode on or off.
An indicator light on the button will come on to let you
know the recirculation mode is activated. This is normal.
Recirculation is available in the bi-level, and vent
modes. Recirculation is not available, and the light will
not come on, while in oor, oor/defog and defrost
mode. If recirculation is selected in these modes, the
indicator will ash three times indicating it is not
available in that mode.
H(Vent):Turn the right knob on the control panel to
this mode to direct air to the instrument panel outlets.
\(Bi-Level):Turn the right knob on the control panel
to this mode to direct air to the instrument panel outlets,
and the remaining air to the oor outlets and the defroster
and side window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):Turn the right knob on the control panel to
this mode to direct air to the oor outlets, side window
outlets, and defroster. Recirculation is not available
in this mode.
Defogging and Defrosting
Fog 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. There are two modes to clear fog or frost from
your windshield and side windows. 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. For best results, clear
all snow and ice from the windshield before defrosting.
/(Floor/Defog):Turn the right knob on the control
panel to this mode to direct the air to the windshield, the
side window outlets, and to the oor outlets. When
you select this mode, the system runs the air
conditioning system unless the outside temperature is
near freezing or below. Recirculation is not available
in this mode.
3-22

0(Defrost):Turn the right knob on the control panel
to this mode to direct most of the air to the windshield,
and the side window outlets. When you select this mode,
the system runs the air conditioning system unless
the outside temperature is near or below freezing.
Recirculation is not available in this mode.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window when the key
is in the ignition and turned to ON.
=(Rear Defogger):Press the right knob on the
control panel to turn the rear window defogger on or off.
First press of this button will activate the rear window
defogger for 15 minutes and each subsequent activation
lasts 7 and one-half minutes.
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 air outlets located in the center and on the side
of your instrument panel to direct the airow.
Your vehicle has air outlets that allow you to adjust the
direction and amount of airow inside the vehicle.
Move the louvers up or down to change the direction of
the airow. Use the thumbwheel under the outlets to
change the direction of the airow from left to right.
Operation Tips

Enable recirculation mode for maximum air
conditioning performance.
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 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.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly — and even dangerous. So please get to know
your warning lights and gages. They are a big help.
Your vehicle has a DIC that works along with the
warning lights and gages. SeeDriver Information
Center (DIC) on page 3-41for more information.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know
how fast you are going, about how much fuel you have used, and many other things you will need to know to drive
safely and economically.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles or kilometers.
The odometer mileage can be checked with the ignition
off. Simply press the trip information stem. See
“Odometer” underDIC Controls and Displays on
page 3-41for more information.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it cannot, then it is set at zero, and a label
must be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
Your vehicle has a trip odometer that can tell you how
far your vehicle has been driven since you last set
the trip odometer to zero.
See “Trip Odometer” underDIC Controls and Displays
on page 3-41for more information.
Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
