2008 PONTIAC GRAND PRIX instrument panel

Care of the HUD
Clean the inside of the windshield as needed to remove
any dirt or lm that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft, clean cloth that
has household glass cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not spray cleaner
directly on the lens because the cleaner could leak
into the unit.
If You Cannot See the HUD Image
When the Ignition Is On
Is anything covering the HUD lens?
Is the HUD dimmer setting bright enough?
Is the HUD image adjusted to the proper height?
Are you wearing polarized sunglasses?
Still no HUD image? Check the fuse in the
instrument panel fuse block. SeeInstrument
Panel Fuse Block on page 5-122.
If the HUD Image Is Not Clear
Is the HUD image too bright?
Are the windshield and HUD lens clean?
If the HUD image is not correct, contact your
dealer/retailer.
Keep in mind that the windshield is part of the HUD
system. SeeWindshield Replacement on page 5-61.

9(Off):Turn the knob to this position to turn the
climate control system off. Only the heated seat and/or
rear defrost can be operated when the fan is off.
Mode
Turn the middle knob to select the following modes:
H(Vent) (Outside Air):This mode directs outside air
to the instrument panel outlets. If driving in city traffic,
and the vehicle is stopped and idling, or the weather is
hot, press the recirculation button. To prevent the air
inside the vehicle from becoming stale, be sure to turn
off recirculation periodically.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to the oor
outlets. Some air may be directed toward the windshield.
Slightly cooler air is directed to the instrument panel
outlets and warmer air is directed to the oor outlets.
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 40°F (4°C) or below.
3-28

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 to turn the
air conditioning compressor on or off. An indicator light
to the right of the button will come on. This button
has no control over the air conditioning compressor
when in Floor/Defog and Defrost modes. The instrument
panel brightness control may have to be adjusted to
the highest setting in order to see the indicator.
SeeInstrument Panel Brightness on page 3-19for
additional information.
On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for
the 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 any mode setting between vent and the
setting before defrost.
2. Select the air conditioner.
3. Select the coolest temperature.
4. Select the highest climate control fan speed.
Using these settings will set recirculation for quicker
cool down (the light indicator will not turn on). If outside
air is desired, press the recirculation button twice.
Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this from happening, after ve minutes
the recirculation door will open slightly to allow some
outside air into the vehicle.
The air conditioning system removes moisture from the
air, so sometimes there may be a small amount of
water dripping underneath the vehicle while it is idling
or after the engine is turned off. This is normal.
3-30

Recirculation
h
(Recirculation):Press this button to activate the
recirculation mode. With this selection, inside air is
recirculated into the vehicle. This mode reduces outside
air and odors from entering the vehicle. It may also help
to heat or cool the air inside the vehicle more quickly.
An indicator light to the right of the button will come on
to show that the recirculation button has been pressed.
The instrument panel brightness control may have to be
adjusted to the highest setting to see the indicator.
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: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.

Dual Automatic Climate Control
System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):Turn both the fan and mode knob to
AUTO for automatic control of the inside temperature, the
air delivery mode and the fan speed. You may notice a
delay of two to three minutes before the fan comes on
when the automatic operation is used in cold weather.For the automatic system to function, the temperature
must be set between 60°F (15°C) and 90°F (32°C).
1. Adjust the temperature to a comfortable setting.
2. Press the PASS button to turn the passenger
climate control system on and off. When the
passenger system is off, the driver’s temperature
setting is also used for the passenger and the
passenger display is off.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for the air to warm up
will depend on the outside temperature and the
length of time that has elapsed since your vehicle
was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
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

from coming in the vehicle. It can be used to help reduce
the outside air and odors that may enter the vehicle or
help to cool the air inside the vehicle quicker.
Recirculation is not available in defrost or oor/defog
mode. Pressing the recirculation button will turn on the
indicator light.
Using recirculation for long periods of time may cause the
air inside your vehicle to become too dry. To prevent this
from happening, after the air in your vehicle has cooled,
turn the recirculation mode off.
z(Heated Seats):Press this button to turn the heated
seats on and off. The button on the left controls the
driver’s seat and the button on the right controls
the passenger’s seat. SeeHeated Seats on page 1-4
for additional information.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
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. Use the oor/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.
3-34

Outlet Adjustment
Turn the air outlets, located in the middle and at each
outboard side of the instrument panel, to adjust the
direction of the airow.
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 the 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 the vehicle more
effectively.
If the airow seems low when the fan is at the
highest setting, the passenger compartment air
lter may need to be replaced. See “Passenger
Compartment Air Filter” following, for more
information.
Passenger Compartment Air Filter
The passenger compartment air lter is located near the
passenger’s side windshield wiper arm, under the
inlet grille.
The lter traps most of the pollen from entering the
climate control system. Similar to the engine’s air lter,
it may need to be changed periodically to insure
system performance. SeeScheduled Maintenance on
page 6-4for more information.
To change the passenger compartment air lter,
1. Turn the ignition to ACC/ACCESSORY and the
windshield wipers on.
2. Turn the ignition to LOCK/OFF when the windshield
wipers are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose from
the fender rail and the air inlet grille.
5. Remove the hood weather-strip from the
passenger’s side of the vehicle, peeling it back
halfway.
