2004 PONTIAC GRAND PRIX section 5

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.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on brie¯y when you start the engine
just to let you know they're working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages
and warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Follow this manual's
advice. Waiting to do repairs can be costly ± and even
dangerous. So please get to know your warning
lights and gages. They're a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
See
Driver Information Center (DIC) on page 3-45for
more information.

Uplevel DIC with Trip Computer
The Driver Information Center (DIC) control buttons and
the message display screen are located above the radio.
The DIC gives you important safety and maintenance
facts concerning the vehicle. The status of many of the
vehicle's systems along with driver personalization
menus and warning messages about your vehicle's
systems may display on the DIC screen.
The outside temperature automatically appears on the
bottom right corner of the DIC display screens. If the
outside temperature is below 38ÉF (3ÉC), the temperature
reading will toggle between displaying the outside
temperature and the word ICE for two minutes. If there is
a problem with the system that controls the temperature
display, the letters OC (Open Circuit) or SC (Short
Circuit) will appear on the display. If this occurs, have the
vehicle serviced by your dealer.
The vehicle's transaxle position, and the direction the
vehicle is traveling will also appear on the DIC screen.The compass is self-calibrating, which eliminates the
need to manually set the compass. However, under
certain circumstances, such as during a long distance
cross-country trip, it will be necessary to compensate
for compass variance and reset the zone through
the DIC. See ªSetting the Compassº later in this section
for more information.
The buttons on the DIC trip computer are:

CD-R has been handled. You may experience an
increase in skipping, difficulty in ®nding tracks, and/or
difficulty in loading and ejecting. If these problems occur
try a known good CD.
