PONTIAC GRAND PRIX 2004 Owners Manual

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.

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 your vehicle.
·Use of non-GM approved hood de¯ectors 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 your vehicle more
effectively.
·If the air¯ow seems low when the fan is at the
highest setting, the passenger compartment air ®lter
may need to be replaced. See ªPassenger
Compartment Air Filterº following, for more
information on this ®lter.
Passenger Compartment Air Filter
The passenger compartment air ®lter is located
underneath the inlet grille, which is located under
the passenger side windshield wiper arm.
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. See
Part A: Scheduled
Maintenance Services on page 6-4for information
on scheduled changes for this ®lter.

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.
3-31

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know how fast
you're going, about how much fuel is in your tank and many other things you need to drive safely and economically.
Your vehicle is equipped with this cluster or one very similar to it. It has indicator warning lights that are explained on
the following pages. Be sure to read about them.United States version shown, Canada similar
3-32

Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer, located on the Driver Information Center
(DIC) display, shows how far your vehicle has been
driven, in either miles or kilometers. See
DIC Controls
and Displays on page 3-45for more information.
If the vehicle has the Head-Up Display (HUD), the speed
will also be displayed on the HUD screen.
You may wonder what happens if a vehicle has to have
a new odometer installed. It the new one can be set
to the mileage total of the old odometer, than that will be
done. If it can't, than it will be set at zero and a label
must be put on the driver's door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer, located in the Driver Information
Center (DIC), tells you how far you have driven since you
last reset it. You are able to see the miles (kilometers) for
two different trips. See
DIC Controls and Displays on
page 3-45for more information on setting the trip
odometer.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:Do not operate the engine with the
tachometer in the shaded warning area, or engine
damage may occur.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will come on for several seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will ¯ash for
several more.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the diagnostic module.
For more information on the air bag system, see
Air Bag
Systems on page 1-48.
This light will come on
when you start your
vehicle, and it will ¯ash
for a few seconds.
Then the light should
go out. This means the
system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
3-34

{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not in¯ate in a crash, or they
could even in¯ate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ¯ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it ®xed so it will
be ready to warn you if there is a problem.
Up-Shift Light
This symbol can appear
on the instrument panel
if the vehicle has a
supercharged engine and
the shift lever is in the
MANUAL (M) transaxle
position.
It will appear as a prompt to up-shift to the next gear
using one of the TAP-ShiftŸ paddles located on
the steering wheel.
This symbol will also appear on the Head Up
Display (HUD).
See
Automatic Transaxle Operation on page 2-22for
more information.

Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on brie¯y when you turn the
ignition key to RUN. If it doesn't come on then, have it
®xed so it will be ready to warn you if there's a problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn't
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set.
The brake warning light may also come on when the
brake ¯uid is low. If this occurs, the LOW BRAKE FLUID
message will also appear in the Driver Information
Center (DIC).
If the brake warning light comes on while you are driving,
pull off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go closer
to the ¯oor. It may take longer to stop. If the light is still
on, have the vehicle towed for service. See
Towing Your
Vehicle on page 4-33.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you've pulled off the road and stopped
carefully, have the vehicle towed for service. United States
