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.
Do not cover the solar sensor located in the
center of the instrument panel, near the
windshield. For more information on the solar
sensor, see “Sensors” later in this section.

Y(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 most of the remaining air to the
oor outlets. In automatic operation, cooler air
is directed to the upper outlets and warmer air to
the oor outlets.
[(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
outboard outlets (for the side windows), and a little
air directed to the windshield.

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 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.
yNz(Mode):Press this button until defog
appears on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows.
When this mode is selected, the system turns off
recirculation and runs the air-conditioning
compressor unless the outside temperature is at
or below freezing. If recirculation mode is selected
while in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the
thumbwheel on the outboard outlets to the side
window defog position. SeeOutlet Adjustment on
page 194for more information.
0(Defrost):Pressing defrost directs most of the
air to the windshield, with some air directed to
the side windows. In this mode, the system
will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the
side window defog position. SeeOutlet Adjustment
on page 194for more information. 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.
The rear window defogger will only work when the
ignition is in ON.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear
window as possible.
193
The rear window defogger will turn off about
10 minutes after the button is pressed, but if the
vehicle’s speed is above 30 mph (48 km/h),
the rear defogger will stay on continuously.
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.
The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the mirror
when the rear window defogger button is on.
SeeOutside Heated Mirrors on page 141.
Notice:Do not try to clear frost or other
material from the inside of the front windshield
and rear window with a razor blade or anything
else that is sharp. This may damage the rear
window defogger grid and affect your radio’s
ability to pick up stations clearly. The repairs
wouldn’t be covered by your warranty.Outlet Adjustment
Use the knobs located in the center of each outlet
to change the direction of the air ow. Use the
thumbwheels to open or close the outlets.
j(Side Window Defog):Turn the thumbwheel
to this symbol to use the side window defog
setting. The air coming through the outlets will be
directed toward the side windows to clear fog.
k(Open):Turn the thumbwheel to this symbol to
open the outlets completely and allow the
maximum amount of air to enter your vehicle.

Battery Saver Active
This message appears when the system detects
that the battery voltage is dropping beyond a
reasonable level. The battery saver system will
start reducing certain features of the vehicle which
you may be able to notice. At the point that the
features are disabled, this message is displayed. It
means that the vehicle is trying to save the
charge in the battery.
Turn off all unnecessary accessories to allow the
battery to recharge.
The normal battery voltage range is
11.5 to 15.5 volts. You can monitor battery voltage
on the DIC by pressing the INFO button until
BATTERY VOLTS appears.
Battery Voltage High
This message indicates that the electrical charging
system is overcharging the battery. When the
system detects that the battery voltage is above
an estimated 16 volts, this message will be
displayed.To reduce the charging overload, use the vehicle’s
accessories. Turn on the exterior lamps and
radio, set the climate control on AUTO and the fan
speed on the highest setting, and turn the rear
window defogger on.
The normal battery voltage range is
11.5 to 15.5 volts when the engine is running. You
can monitor battery voltage on the DIC by pressing
the INFO button until BATTERY VOLTS appears.
Battery Voltage Low
This message will appear when the electrical
system is charging less than 10 volts or if
the battery has been drained.
If this message appears immediately after starting
the engine, it is possible that the generator can
still recharge the battery. The battery should
recharge while driving but may take a few hours to
do so. Consider using an auxiliary charger to
boost the battery after returning home or to a nal
destination. Make sure you follow the
manufacturer’s instructions.

Diversity Antenna System
The AM-FM antenna is integrated within the rear
quarter windows. Make sure the inside surface
of the rear quarter windows are not scratched and
the grid lines on the glass are not damaged. If
the inside surface is damaged, it could interfere
with radio reception.
Notice:Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some
tinting materials will interfere with or distort the
incoming radio reception. Any damage caused
to your antenna due to metallic tinting materials
will not be covered by your warranty.
Notice:Do not try to clear frost or other
material from the inside of the rear quarter
window with a razor blade or anything else that
is sharp. This may affect your radio’s ability
to pick up stations clearly. The repairs wouldn’t
be covered by your warranty.
If static is heard on the radio, when the rear
window defogger is turned on, it could mean that
a defogger grid line has been damaged. If this
is true, the grid line must be repaired.If adding an aftermarket cellular telephone to your
vehicle, and the antenna needs to be attached
to the glass, make sure that the grid lines for the
AM-FM antennas are not damaged. Make sure
the cellular telephone antenna does not touch a
grid line.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the
best performance from the XM™ system if the
sunroof is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.
Of course, you will nd experienced and able
service experts in GM dealerships all across
North America. They will be ready and willing to
help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
312
You can run the engine to keep warm, but be
careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO
(carbon monoxide) gas to get inside.
CO could overcome you and kill you.
You cannot see it or smell it, so you might
not know it is in your vehicle. Clear away
snow from around the base of your
vehicle, especially any that is blocking the
exhaust pipe. And check around again
from time to time to be sure snow does
not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.
Run your engine only as long as you must.
This saves fuel. When you run the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps the battery charged.
