2002 PONTIAC GRAND PRIX instrument panel

2-97
When you sit up straight in your seat, the HUD image
will appear straight ahead near the front bumper.
The HUD also shows the following lights when they are
lit on the instrument panel cluster:

Turn Signal Indicators

High
-Beam Indicator Symbol

Low Fuel Symbol
The HUD will display CHECK GAGES when the
following items are lit on the instrument panel cluster:

Oil Warning Symbol

Coolant Temperature Symbol

Charging System Symbol
When the ignition key is turned to RUN, the entire HUD
image will come on. Then the Head
-Up Display will
operate normally.
NOTICE:
Although the HUD image appears to be near
the front of the vehicle, do not use it as a parking
aid. The HUD was not designed for that purpose.
If you try to use it that way, such as in a parking
lot, you may misjudge distance and run
into something.
When the HUD is on, the speedometer reading will be
displayed continually. The current radio station or CD
track number will only be displayed for three seconds
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed,
either on the radio itself or on the optional steering
wheel controls.

2-98
To adjust the HUD so you can see it properly do
the following:
1. Adjust your seat, if necessary, to a
comfortable position.
2. Start the engine and adjust the HUD controls located
on the instrument panel, to the right of the steering
wheel. Move the DIM thumbwheel up or down to
adjust brightness.3. Press the top of the UP/DN switch until the HUD
image stops moving. Then press the bottom of the
switch until the image is as low as possible but in
full view.
4. Move the DIM thumbwheel down until the HUD
image is no brighter than necessary. To turn the HUD
off, move the DIM thumbwheel all the way down.
If the sun comes out, it becomes cloudy, or if you turn
on your headlamps, you may need to adjust the HUD
brightness again. Polarized sunglasses could make the
HUD image harder to see.
Push the ENG/MET button
on the trip calculator,
located above the audio
controls on the trip
computer (if equipped) on
the instrument panel, to
switch the HUD display
from English to metric or
metric to English.
If your vehicle is not equipped with the trip calculator,
you cannot change the display.

2-99 Care of the Head-Up Display
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. 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 Can't See the HUD Image When the Ignition
Is On

Is anything covering the HUD unit?

Is the HUD dimmer setting bright enough?

Is the HUD image adjusted to the proper height?

Still no HUD image? Check the fuse in the
instrument panel fuse block. See ªFuses and Circuit
Breakersº in the Index.
If the HUD Image Is Not Clear

Is the HUD image too bright?

Are the windshield and HUD lens clean?
The windshield is part of the HUD system. If you ever
need a new windshield, be sure to get one designed for
HUD. If you don't, the HUD image may look blurred
and out of focus.

Comfort Controls
Dual Climate Control System
This system allows the driver and passenger to maintain
separate temperature settings. The system works best if
you keep the windows closed while using it.
Fan Knob
The knob on the left side of the climate control panel
regulates the fan speed. To turn the fan off, turn the
knob to OFF. The fan must be on for the air
conditioning compressor to operate.Driver's Temperature Lever
The lever on the left adjusts the air temperature on the
driver's side of the vehicle only. The passenger's side
has its own lever for temperature control. Slide the lever
upward to raise the temperature. Slide the lever
downward to lower the temperature.
Passenger's Temperature Lever
The lever on the right adjusts the air temperature on the
passenger's side of the vehicle only. The driver's side
has its own lever for temperature control. Slide the lever
upward to raise the temperature. Slide the lever
downward to lower the temperature.
Mode Knob
The knob on the right side of the climate control panel
has several settings to adjust the direction of the airflow:
MAX (Maximum): This setting recirculates much
of the air inside your vehicle and sends it through
the instrument panel outlets. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 38
F (3.3
C).
(Even when the compressor is running, you can control
the temperature.)

3-3
(Vent): This setting brings in outside air and directs
it through the instrument panel outlets.
(Bi-Level): This setting brings in outside air and
directs it two ways. Half of the air is directed through
the vent outlets. Most of the remaining air is directed
through the floor ducts and a small amount to the defrost
and side window vents.
(Floor): This setting sends most of the air through
the ducts near the floor. The remaining airflow comes
out of the defroster and side window vents.
(Defogger): This setting allows half of the air to
go to the floor ducts and half to the defroster and side
window vents.
FRONT (Defroster): This setting directs most of
the air through the defroster. Some of the air goes to the
floor ducts and the side window vent. The air conditioning
compressor will run automatically in this setting unless the
outside temperature is below 38
F (3.3
C).
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioning
compressor. The indicator light above the button will
glow when the button is pressed. You don't have topress the button to run the compressor in MAX
or defrost because it will already be running in
these modes.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time it takes for
the vehicle to cool down.
For quick cool down on very hot days, turn the fan on
and use MAX with the temperature levers all the way in
the blue area. If this setting is used for long periods of
time, the air in your vehicle may become too dry.
For normal cooling on hot days, turn the fan on and use
vent with the temperature levers in the blue area and the
A/C button pressed in. The system will bring in outside
air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use bi
-level with the temperature
levers in the middle and the A/C button pushed in. The
system will bring in outside air and direct it to your
upper body, while sending slightly warmed air to your
lower body.

4-42 Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns
than normal. Do this so your trailer won't strike
soft shoulders, curbs, road signs, trees or other
objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument panel
will flash whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also flash,
telling other drivers you're about to turn, change lanes
or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It's important
to check occasionally to be sure the trailer bulbs are
still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle's lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they're all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.

5-11
Engine Overheating
You will find a coolant temperature gage and a warning
light concerning an overheated engine condition on the
instrument panel cluster. See ªEngine Coolant
Temperature Gageº and ªEngine Coolant Temperature
Lightº in the Index. You also have a low coolant light on
your instrument panel cluster. See ªLow Coolant Lightº
in the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle
to be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates firing groups of cylinders
helps prevent engine damage. In this mode, you will notice
a significant loss in power and engine performance. The
low coolant light may come on and the temperature
gage will indicate an overheat condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

6-3
CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.

Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.

Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside of
your vehicle.
Fuel
The 8th digit of your vehicle identification number
(VIN) shows the code letter or number that identifies
your engine. You will find the VIN at the top left of the
instrument panel. See ªVehicle Identification Numberº
in the Index.
Gasoline Octane
If your vehicle has the 3100 V6 engine (VIN Code J)
or 3800 V6 engine (VIN Code K), use regular unleaded
gasoline with a posted octane of 87 or higher. If the
octane is less than 87, you may get a heavy knocking
noise when you drive. If it is bad enough, it can damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher
-octane fuel
is necessary.
If your vehicle has the 3800 Supercharged V6 engine
(VIN Code1), use only premium unleaded gasoline with
a posted octane of 91 or higher. In an emergency, you
may be able to use a lower octane
-- as low as 87 -- if
heavy knocking does not occur. Refill your tank with
premium fuel as soon as possible. If you are using
91 octane or higher
-octane fuel and you hear heavy
knocking, your engine needs service.
