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 choose from to clear fog or frost
from your windshield. 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.
Turn the right knob to select the defog or
defrost mode.
-(Defog):Turn the knob to this setting to
direct the air between the windshield
and the oor outlets with a small amount directed
to the side windows. This mode automatically
turns off recirculation. The air conditioning
compressor runs unless the outside temperature
is at or below freezing. The air conditioning
compressor operates although the indicator light
is not on. The air conditioning indicator
light turns off when defog is selected. If the air
conditioning button is pressed while in
defog mode, the indicator light turns on. If the
button is pressed again, the light turnsoff. The recirculation mode cannot be selected
while in the defog mode. Do not drive the
vehicle until all the windows are clear.
1(Defrost):Turn the knob to this setting to
direct most of the air to the windshield with some
air directed to the oor vents. In this mode, the
system automatically forces outside air into
the vehicle. The air conditioning compressor runs
unless the outside temperature is at or below
freezing. The air conditioning compressor operates
although the indicator light is not on. The air
conditioning indicator light turns off when defrost is
selected. If the air conditioning button is pressed
while in defrost mode, the indicator light turns on. If
the button is pressed again, the light turns off.
Recirculation cannot be selected while in the
defrost mode.
To help clear the windshield quickly, do the
following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
window defogger on or off. An indicator light
comes on to indicate that the rear window
defogger is on. Be sure to clear as much snow as
possible from the rear window.
If driving below 50 mph (80 km/h), the rear window
defogger turns off about 15 minutes after the
button is pressed. If turned on again, the defogger
only runs for about seven and one-half minutes
before turning off. The defogger can also be turned
off by pressing the button again or by turning off
the engine.If your vehicle’s speed is maintained above
50 mph (80 km/h), the rear window defogger
remains on once the button is pressed.
If your vehicle has the remote start feature, the
rear defogger automatically turns on if it is
cold outside. When the vehicle transitions out of
the remote start mode, the rear defogger turns off.
SeeRemote Keyless Entry System Operation
on page 101.
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.

H(Vent):Turn the knob to this position to direct
air to the instrument panel outlets.
)(Bi-Level):Turn the knob to this position to
direct half of the air to the instrument panel outlets,
and the remaining air to the oor outlets.
6(Floor):Turn the knob to this position to direct
most of the air to the oor outlets with some air
directed to the side window outlets and windshield.
The right knob can also be used to select defog
or defrost modes. See Defogging and Defrosting
later in this section.
:(Outside Air):Press the right side of this
button to turn the outside air mode on. Air
from outside the vehicle circulates throughout your
vehicle. An indicator light will come on to let you
know that it is activated. The outside air mode can
be used with all modes, but it cannot be used
with the recirculation mode. Pressing this button
will cancel the recirculation mode.
?(Recirculation):Press the left side of the
button to turn the recirculation mode on. The
air inside the vehicle is recirculated through the
climate control system and throughout the vehicle,not from outside. This mode is helpful when you
are trying to limit odors from entering your
vehicle and for maximum air conditioning
performance in hot weather. An indicator light
above the button will come on to let you know that
it is activated. It blinks three times if you try to
use recirculation in a mode that it can not be used
in. Only use this mode when it is needed for
comfort, since window fogging will rapidly occur if
the air conditioning compressor is not engaged.
Press this button to cancel the auto recirculation
feature. Each time the vehicle is started, the
system reverts to the auto recirculation function.
If recirculation is selected while in defrost, defog or
oor, the light on the button will ash three
times and go out to let you know this is not
allowed. This is to prevent window fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of
time can cause fogging of the vehicle’s windows.
To clear the fog, select either defog or defrost.
Make sure the air conditioning is on.
189

Temperature Control:Press the up and down
arrows to increase or decrease the temperature
inside the vehicle.
#(Air Conditioning):Press this button to turn
the air conditioning compressor on and off. A
light above the button will come on while the air
conditioning is on.
When air conditioning is selected or in AUTO
mode, the system runs the air conditioning
automatically to cool and dehumidify the air
entering the vehicle.
On hot days, open the windows long enough to let
hot inside air escape. This reduces the time it
takes for your vehicle to cool down. Then keep the
windows closed for the air conditioner to work
its best.On cool, but sunny days while using manual
operation of the automatic system, use bi-level to
deliver warm air to the oor and cooler air to
the instrument panel outlets. To warm or cool the
air, press the temperature buttons to the desired
setting.
In AUTO mode the system will cool and dehumidify
the air inside the vehicle. Also while in AUTO
mode, the system will maximize its performance
by using recirculation as necessary.
Heating:On cold days when using manual
operation of the automatic system, choose oor
mode to deliver air to the oor outlets. To warm or
cool the air delivered, push the temperature
buttons to the desired setting.
If you want to use the automatic mode, turn the
knob to AUTO and adjust the temperature by
pressing the temperature buttons.
The heater works best if you keep the windows
closed while using it.

Defogging and Defrosting
You can use either defog or front defrost to clear
fog or frost from the windshield.
-(Defog):Use to clear the windows of fog or
moisture. Turn the mode knob to this position
to select this setting. This setting delivers air to the
oor and windshield outlets.
0(Defrost):Turn the mode knob to this position
to defrost the windshield. The system automatically
controls the fan speed if AUTO mode is selected.
If the outside temperature is 40°F (4°C) or
warmer, the air conditioning compressor
automatically runs to help dehumidify the air and
dry the windshield. The air conditioning indicator
light blinks three times if you try to turn off
the compressor while in this mode.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press this button to turn the rear
window defogger on or off. An indicator light above
the button comes on to indicate that the rear
window defogger is activated.If driving below 50 mph (80 km/h), the rear window
defogger will turn off about 15 minutes after the
button is pressed. If turned on again, the defogger
will only run for about seven and one-half
minutes before turning off.
If your vehicle’s speed is maintained above
50 mph (80 km/h), the rear window defogger
remains on once the button is pressed.
If your vehicle has the remote start feature, the
rear defogger automatically turns on if it is
cold outside, but the indicator light does not come
on. When the vehicle transitions out of remote
start mode the rear defogger turns off.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Rotate the instrument panel outlets and move the
louvers on the outlets to change the direction
and amount of airow in your vehicle.

Operation Tips
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.
When an objectionable odor outside the vehicle
is encountered, use the recirculation mode,
with the temperature knob at a comfortable
setting to prevent the odor from entering the
vehicle through the ventilation system. This can
be helpful when driving through a long tunnel
with poor ventilation. However, extended usage
of this mode in cold or cool weather can cause
window fogging.
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 could be or
there 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 could be or there 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. Follow this manual’s advice. Waiting to do
repairs can be costly — and even dangerous. Get
to know your warning lights and gages. They
are a big help.
192

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, how much fuel you have, and many other things you will need to drive
safely and economically.
Your vehicle has this cluster or one very similar to it. It includes indicator warning lights and gages that
are explained on the following pages. Be sure to read about them.

Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts, unless the
driver’s safety belt is already buckled.
The safety belt light will
also come on and stay
on for several
seconds, then it will
ash for several more.
This chime and light is repeated if the driver
remains unbuckled and the vehicle is in motion.
If the driver’s belt is already buckled, neither
the chime nor the light will come on.
Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to ON or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag
is enabled. SeePassenger Sensing System on
page 87for more information. The passenger
safety belt light will also come on and stay on for
several seconds, then it will ash for several more.
This chime and light is
repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
195

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensors, the airbag modules,
the wiring and the diagnostic module. For
more information on the airbag system, seeAirbag
System on page 76.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
If there is a problem with the airbag system in
your vehicle, the SERVICE AIR BAG message will
appear on the DIC display. SeeDIC Warnings
and Messages on page 212for more information.

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. If you use
remote start to start your vehicle, if you have
this feature, you may not see the system check.
Then, after several more seconds, the status
indicator will light either ON or OFF, or either the
on or off symbol to let you know the status of
the right front passenger’s frontal airbag.If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag. A
child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
