2004 PONTIAC GRAND PRIX air conditioning

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.

DIC Warnings and Messages
These messages will appear if there is a problem in
one of the vehicle's systems. They will override
any other mode or screen the DIC may be in.
Some messages allow you to erase them from the
DIC screen. To do this you must acknowledge
the message. To acknowledge or clear the message
from the screen, press the set/reset button on the DIC.
See
DIC Controls and Displays on page 3-45for

the message is resolved, it can be acknowledged and
the screen can be reset.
Be sure to take any message that appears on the
DIC screen seriously and remember that clearing the
messages that are able to be acknowledged, will
only make the message disappear, not the problem.
A/C OFF FOR ENGINE PROTECTION
This warning message appears when the engine coolant
becomes hotter than the normal operating temperature.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.

Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
®ttings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
Throttle System Inspection
Inspect the throttle pedal system for interference or
binding, and for damaged or missing parts. Replace
parts as needed. Replace any components that
have high effort or excessive wear.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
cha®ng, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or
conditions result in frequent braking.
