2-73 Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per square inch)
when the engine is running.
Canadian vehicles indicate
pressure in kPa
(kiloPascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the red
warning zone indicate the normal operating range.
A reading in the red zone may be caused by a
dangerously low oil level or other problem causing low
oil pressure. On vehicles with the optional DIC, the
CHECK GAGES light will go on and a warning chime
will sound, if you have this option. Driving your vehicle
with low oil pressure can cause extensive
engine damage.CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-74 Check Oil Level Warning Light
The CHECK OIL LEVEL
light turns on for three
seconds as a bulb check
each time the ignition key is
turned to RUN. If the light
doesn't turn on, have your
vehicle serviced.
If the engine oil is more than one quart (0.95 L) low and
the engine has been shut off for at least eight minutes,
the CHECK OIL LEVEL light will turn on for about
one minute and will then remain off until the next time
you start the vehicle.
If the CHECK OIL LEVEL light turns on, the engine oil
level should be checked at the dipstick then brought up
to the proper level, if necessary. See ªEngine Oilº in
the Index.
Low Washer Fluid Warning Light
This light will come on
when your windshield
washers are working and the
fluid container is less than
one
-third full.
Check Gages Warning Light (Option)
This light will come on
briefly when you are
starting the engine.
If the light comes on and stays on while you are driving,
check your gages for fuel, coolant temperature, oil
pressure or voltage. This light will stay on if your engine
is not running with the ignition on.

yellowblue
2-77 Boost Gage (Option)
Vehicles equipped with the supercharged engine have
this boost gage that indicates vacuum during light to
moderate throttle and boost under heavier throttle. The
gage displays the air pressure level in psi going into the
engine's combustion chamber.
The gage is automatically centered at zero psi every
time the engine is started. Actual vacuum or boost is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains and changing
weather, will slightly change the zero reading.
Head-Up Display (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the optional Head-Up Display (HUD), you
can see some of the driver information also available on
your instrument panel cluster. The information may be
displayed in English or metric units and appears as a
reflection on the windshield. The HUD shows:

Speedometer reading

Turn signal indicators

High
-beam indicator symbol

CHECK GAGES message (for low oil pressure, high
coolant temperature, low oil level and low fuel)

Low fuel warning symbol

FUNCTION MONITOR: This lets you know if
you are low on fluids or have a problem with a
vehicle function:

CHECK OIL LEVEL: This message could mean
your oil level is low. If it comes on for more than
three seconds, see ªCheck Oil Level Warning Lightº
in the Index.

WASHER FLUID: This message means your
washer fluid tank is less than about 30 percent full.
The windshield portion of the vehicle outline will
also glow. If these come on, see ªWindshield Washer
Fluidº in the Index.

LOW COOLANT: This message means your
coolant level has fallen to about half full. If it comes
on, see ªEngine Coolantº in the Index.

CHECK GAGES: If this light comes on and stays
on while you are driving, check your gages for fuel,
coolant temperature, oil pressure or battery voltage.
SECURITY MONITOR: The vehicle outline will
illuminate to let you know the following information:

DOOR AJAR: This message means a door is not
fully closed. The vehicle outline will show you
which door it is.
TRUNK AJAR: This message appears if the trunk is
not fully closed. The vehicle outline will illuminate.

HOOD AJAR: This message appears if the hood is
not fully closed. The vehicle outline will illuminate
if the hood is not latched properly.
LAMP MONITOR: Whenever you try to use one of
the following lamps, the LAMP MONITOR will tell you
if a bulb is out.

Headlamp (Low and High Beam)

Parking Lamp/Sidemarker

Turn Signal/Parking/Stop

Back
-Up Lamp

Taillamp/Turn/Sidemarker/License

Brake Lamp and Center High
-Mounted Stoplamp
If a bulb is out, you will see a message, such as PARK
LAMP, and you will also see where the problem is on
the vehicle outline. The message stays on until the
problem is fixed. See ªReplacement Bulbsº in the Index
for bulb details.

The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Pontiac dealerships all across North America. They'll be
ready and willing to help if you need it.Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
H±45±0741±T
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Engine Cooling Fans
CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down.
