climate control PONTIAC GRAND PRIX 2008 User Guide

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.

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
in this section.

?(Recirculation):Press this button to turn the
recirculation mode on or off. This mode keeps outside air
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.

Compass Calibration
The compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle
in circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers,
or other industrial structures, if possible.
If the DIC display does not show a heading, for example,
N for North, or the heading does not change after
making turns, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic CB or cell phone antenna
mount, a magnetic emergency light, magnetic note
pad holder, or any other magnetic item. Turn off
the vehicle, move the magnetic item, then turn on
the vehicle and calibrate the compass.
To adjust for compass variance and to calibrate the
compass, use the following procedure:
Compass Variance (Zone) and Calibration
Procedure
1. Do not set the compass zone when the vehicle is
moving. Only set it when the vehicle is in PARK (P).
Press the options button until COMPASS
CALIBRATION MODE displays.2. Find the vehicle’s current location and variance
zone number on the map.
Zones 1 through 15 are available.
3. Press the set/reset button to scroll through and
select the appropriate variance zone.
4. Press the options button to advance to the
calibration screen.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.

Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the
norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specied government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.
Warning
:The traction grade assigned to this
tire is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specied indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning
:The temperature grade for this tire
is established for a tire that is properly inated
and not overloaded. Excessive speed,
underination, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.

4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the inator kit on/off switch (B) is in the
O (off) position.
5. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 3-26for more
information.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-36.
6. Start the vehicle. SeeStarting the Engine on
page 2-25for more information. The vehicle must be
running while using the air compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
7. Move the inator kit switch to the I (on) position.
The inator kit will force sealant and air into the
tire. Sealant may leak from the puncture hole until
the vehicle is driven and the hole has sealed.
