Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or 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. 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.
Select one of these available modes from the
right knob.
É(Defog):This mode directs most of the air to the
windshield and the floor outlets. A small amount of air is
also directed to the outboard outlets for the side
windows and to the instrument panel side outlets.
When you select this mode, the system runs the
air-conditioning compressor. To defog the windows
faster, turn the temperature control knob clockwise to
the warmest setting.
0(Defrost):This mode directs most of the air to the
windshield and the outboard outlets for the side
windows. A small amount of air is also directed to the
instrument panel side outlets.
When you select this mode, the system runs the
air-conditioning compressor. To defrost the windows
faster, turn the temperature control knob clockwise
to the warmest setting.
Do not drive the vehicle until all windows are clear.
Front Heated Windshield
Your vehicle may have a heated front windshield which
can be used with defog and defrost. This feature will
only work when the ignition is turned to ON.
The front heated windshield uses a heated element to
remove fog or frost from the bottom of the windshield.
<(Rear):Press this button to heat the front
windshield. The button is located below the audio
system. An indicator light in the button will come on to
let you know that the feature is activated. The front
windshield heater will turn off about ten minutes after the
button is pressed. It can also be turned off by pressing
the button again or by turning off the engine. See
“Rear Window and Outside Mirror Defogger” later in this
section for more information on this button.

Rear Window and Outside Mirror
Defogger
Your vehicle may have a rear window and outside
mirror defogger. This feature will only work when the
ignition is turned to ON.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before using
this feature, clear as much snow from the rear
window as possible.
<(Rear):Press this button to turn the rear window
and outside mirror defogger on or off. An indicator
light in the button will come on to let your know that the
rear window defogger is activated.
The rear window defogger will turn off about 10 minutes
after the button is pressed. The defogger can also be
turned off by pressing the button again or by turning off
the engine. See “Front Heated Windshield” earlier in
this section for more information on this button.
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 lever located in the center of each outlet to
change the direction of the airflow. Use the thumbwheel
located below the outlets to turn them on and off.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors 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.

Safety Belt Reminder Light
The safety belt light will
come on and stay on until
the driver’s safety belt
is buckled.
If the driver’s belt is already buckled, the light will not
come on.
Safety Belt Reminder Tone
If your vehicle has this feature, a tone will sound for
several seconds when the ignition is turned to ON
to remind people to fasten their safety belts. The tone
will not sound if the driver’s safety belt is already
buckled.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, 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
sensor, the airbag modules, the wiring and the crash
sensing and diagnostic module. For more information on
the airbag system, seeAirbag System on page 1-52.
This light will come on
when you start your
vehicle, and it will flash 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.
