2004 PONTIAC GRAND PRIX window

6(Floor):This mode directs most of the air to the ¯oor
outlets with some air directed toward the side window
outlets and a little air directed to the windshield.
In this mode, the system will automatically use outside
air. The air conditioning compressor will be engaged
unless the outside temperature is 40É F (4ÉC) or below.
Recirculation cannot be selected when in this mode.
The middle knob on the climate control panel can also
be used to select the defog or defrost mode.
Defogging and Defrosting
Fog on the inside of the vehicle 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
frost or fog from the windshield. Use the defog mode
to clear the windows of condensation and to warm the
vehicle's occupants. Use the defrost mode to remove
frost or condensation from the windshield quickly.
See ªRear Window Defoggerº later in this section for
information on clearing the rear window of fog or ice.There are two modes to clear fog from your windshield.
Recirculation cannot be selected when in these modes.
.(Floor/Defog):Use the ¯oor/defog mode to clear the
windows of fog or moisture and warm the passengers.
This mode directs the air equally between the
windshield and the ¯oor outlets, along with some
directed to the side window outlets.
This mode will automatically use outside air. The air
conditioning compressor will be engaged unless
the outside temperature is 40É F (4ÉC) or below.
1FRONT (Defrost):Use the front/defrost mode to
remove fog or frost from the windshield more quickly.
This mode directs most of the air to the windshield and
the side window outlets, with some air directed to
the ¯oor outlets. This mode has a timer and will shut off
after ®ve minutes.
This mode will automatically use outside air. The air
conditioning compressor will be engaged unless
the outside temperature is 40É F (4ÉC) or below.

Temperature
The knob on the right of the climate control panel is the
temperature adjustment that can be used with any of
the climate control modes.
Turn the knob clockwise for warmer settings and
counterclockwise for colder settings.
Air Conditioning
#
(Air Conditioner):Press this button on the climate
control panel to turn the air-conditioning system on
or off. When A/C is pressed, an indicator light to the right
of the button will come on to let you know that A/C is
active. The instrument brightness control may have to be
adjusted to the highest setting during the daytime in
order to see the indicator lamp.
On hot days during initial start-up, 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 quicker cool down on hot days, do the following:
1. Select the vent/outside air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside your vehicle to become too dry.
To prevent this from happening, select the vent mode
once the interior of the vehicle is cooled.
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.
3-27

Recirculation
h
(Recirculation):Press this button on the climate
control panel to activate the recirculation mode. With
this selection inside air is recirculated into the vehicle
along with some outside air. This mode reduces outside
air and odors from entering your vehicle. It may also
help to heat or cool the air inside your vehicle more
quickly.
When this button is pressed an indicator lamp to the
right of the button will come on to indicate that the
recirculation mode is on. An adjustment to the
instrument panel brightness control to the highest
setting may be required to see the indicator lamp.
The recirculation mode has a timer. After ®ve minutes,
the system's air inlet door will move slightly to allow
for ten percent fresh outside air to maintain interior air
quality. The only way to reset the system to full
recirculation is to restart the ®ve minute timer by
selecting vent/outside air and recirculation again.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Be sure to
clear as much snow from the rear window as possible.
Notice:Don't use a razor blade or something
else sharp on the inside of the rear window. If you
do, you could cut or damage the defogger 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.
=(REAR):Press this button to turn the rear window
defogger on or off.
When this button is pressed an indicator light to the right
of the button will come on to show that the rear window
defogger is active. The instrument brightness control may
have to be adjusted to the highest setting during the
daytime in order to see the indicator light.
The rear window defogger will turn off approximately
20 minutes after the button is pressed. If reselected,
it will run another 20 minutes. The defogger can
be turned off by pressing the button again or by turning
off the engine.
Do not drive the vehicle until all windows are clear.

Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Be sure that the
inside surface of the rear window is not scratched and
that the lines on the glass are not damaged. If the inside
surface is damaged, it could interfere with radio
reception. Also, for proper radio reception, the antenna
connector at the top-center of the rear window needs to
be properly attached to the post on the glass.
Notice:Do not try to clear frost or other material
from the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio's ability
to pick up stations clearly. The repairs wouldn't
be covered by your warranty.
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
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.If you choose to add a cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, be sure that you do not damage the grid lines for
the AM-FM antenna. There is enough space between
the lines to attach a cellular telephone antenna
without interfering with radio reception
Do not apply aftermarket glass tinting to the back glass.
The metallic ®lm in some tinting materials will interfere
with or distort the incoming radio reception. Care must be
taken when cleaning the rear window because it breaks
in the resistive material heating element and will
adversely affect radio and defogger performance.
See your dealer for details.
XMŸ Satellite Radio Antenna
System (United States Only)
Your XMŸ 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.
The performance of your XM system may be affected
if your sunroof is open.

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're ready. Try to be well rested. If you
must start when you're not fresh Ð such as after a day's
work Ð don't 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's ready to go. If it needs
service, have it done before starting out. Of course,
you'll ®nd experienced and able service experts in
GM dealerships all across North America. They'll 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?
·Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all in¯ated to
the recommended pressure?
·Weather Forecasts:What's the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
·Maps:Do you have up-to-date maps?
4-25

·Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags,
rags, ¯oor mats ± anything you can wrap around
yourself or tuck under your clothing to keep warm.
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 can't 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
your exhaust pipe. And check around again
from time to time to be sure snow doesn't
collect there.
Open a window just a little on the side of the
vehicle that's 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. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can.
To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour
or so until help comes.If You Are Stuck: In Sand, Mud,
Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin your
wheels too fast. The method known as ªrockingº can
help you get out when you're stuck, but you must
use caution.
{CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transaxle or other parts of the vehicle
can overheat. That could cause an engine
compartment ®re or other damage. When you're
stuck, spin the wheels as little as possible.
Don't spin the wheels above 35 mph (55 km/h)
as shown on the speedometer.
