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.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the lighter, press it in all the way, and let
go. When it’s ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could
be blown. Do not hold a cigarette lighter
in while it is heating.
Climate Controls
Climate Control System
This system controls the heating, cooling, and
ventilation of the 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 centered 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

#(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 be
lit when the air conditioning is turned on. This
system cools and dehumidi es the air entering
the 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.
A slight change in engine performance may occur
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 sometimes there may be a small amount
of water dripping underneath the 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.
9(Off):Turn the center knob to this position
to turn the fan off. With the fan off, you may
still experience air ow from the system that
increases with vehicle speed depending on the
mode and temperature settings. Enable
recirculation mode to stop this air ow from
occurring.
The right knob on the control panel is used to
direct the air ow inside the 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.

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 seven 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 air ow.
Your vehicle has air outlets that allow you to
adjust the direction and amount of air ow inside
the vehicle. Move the louvers up or down to
change the direction of the air ow. Use the
thumbwheel under the outlets to change the
direction of the air ow 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 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
of your vehicle more effectively.

{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
With the Anti-Lock Brake
System (ABS), this light
will come on brie y when
you start your engine
to show it is working.
Then it will turn off.
This is normal.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the regular
brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also
on, you do not have anti-lock brakes and there
is a problem with your regular brakes. SeeBrake
System Warning Light on page 182.
The ABS warning light should come on brie y
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
