When you open either a front door or a rear door, the
lamps inside your vehicle will go on. In addition, if
your vehicle is equipped with remote keyless entry, the
light will come on when the remote keyless entry
UNLOCK button is pressed.
After you exit the vehicle and all of the doors have
been closed, the lamps will stay on for an additional
20 seconds before fading off. The lamps will also fade
to off when the key is inserted and turned to RUN
or ACCESSORY, or the LOCK button on the remote

protection system will automatically turn the lamp off
after 20 minutes. This will avoid draining the battery.
This system does not protect against leaving on
the headlamps or parking lamps.
To reactivate the interior lamps, do one of the following:
Turn the ignition on.
Turn the activated interior lamp off, then on.
Open any door.
The battery rundown protection feature will also be
activated when any door is left open.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
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 approximately half of
the air to the instrument panel outlets, and then directs
the remaining air to the oor outlets. Cooler air is directed
to the upper outlets and warmer air to the oor outlets.
The right knob can also be used to select defrost mode.
Information on defogging and defrosting can be found
later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
In any setting other than off, the fan will run continuously
with the ignition on. The fan must be turned on to run
the air conditioning compressor.
9(Off):To turn the fan off, turn the knob all the way
counterclockwise to the off position.
h(Recirculate):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 to help heat or
cool the air inside your vehicle more quickly. An indicator
light will come on in this mode. The air-conditioning
compressor also comes on. Operation in this mode
during periods of high humidity and cool outside
temperatures may result in increased window fogging. If
window fogging is experienced, select the defrost mode.
Temperature Control:Turn the center knob clockwise
or counterclockwise to manually increase or decrease
the temperature inside your vehicle.
3-18

#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When this button
is pressed, an indicator light above the button will come
on to let you know the air conditioning is activated.
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.
For quick cool down on hot days:
1. Select the recirculation mode.
2. Select air conditioning.
3. Select the coolest temperature.
4. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, switch from recirculation
to vent, bi-level or oor.
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.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.
Turn the right knob to select the defog or defrost mode.
A(Side Window Defog):This mode directs most
of the air to the oor outlets and outboard outlets, for the
side windows, with some air directed to the windshield.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to the
oor outlets. When you select this mode, the system
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. The air-conditioning
indicator light will also be on in this setting. To defog
the windows faster, turn the temperature control
knob clockwise to the warmest setting.
3-19

0(Defrost):This mode directs most of the air to the
windshield, with some air directed to the side window
outlets and the oor outlets. When you select this mode,
the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The air-conditioning indicator light will also be on in
this setting.
To defog the side windows, set the right knob to oor
and the fan knob to the highest setting. You can use the
air conditioning while in this setting by pressing the air
conditioning button. In both cases, aim the side
outlets toward the side windows. For increased airow
to the side outlets, close the center outlets. 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 from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<(Rear):Press the button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible. An indicator light above
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:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t 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 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.

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 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. See
Brake System Warning Light on page 3-26.

be there to tell you when the system is active.
Engine Coolant Temperature Gage
Your vehicle is equipped with one of these gages. With
the ignition in RUN, this gage shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot! It means that your engine coolant has
overheated. The CHECK GAGES light should come on
if this condition exists. SeeCheck Gages Warning
Light on page 3-34for more information. If you have
been operating your vehicle under normal conditions,
you should pull off the road, stop your vehicle and turn
off the engine as soon as possible.
