4. Before starting the engine, be sure to unplug and store
the cord
as it was before to keep it away from moving
engine
parts. If you don’t, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on
the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle.
The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position to use when
you start your engine because your
vehicle can’t move easily.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
\*
0
/
0 120
3800 V6 Engine 5.7L VS Engine
One of these gages may tell you there could be a
problem with
your engine oil pressure.
The engine oil pressure gage shows the engine oil pressure
in psi (pounds per square inch) in the United States, or kpa
(kilopascals)
in Canada, when the engine is running. On
the 5.7L V8 engine, oil pressure should be 20 to 80 psi
(140 to 550 Pa). On the 3800 V6 engine, the oil pressure
should be between 20 and 120 psi (140 to 827 Wa). It
may vary with engine
speed, outside temperature and oil
viscosity, but readings above the red area show the normal
operating range. Readings
in the red area tell you that the
engine is low
on oil, or that you might have some other oil
problem. See “Engine Oil” in the Index.

A 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.
I Low Oil Light
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered
by
your warranty.
LOW
OIL
Your vehicle is equipped
with an oil level monitoring
system. When you start
your engine, the warning light will come on briefly.
If
the light doesn’t come on,
have it repaired.
If the light stays on after starting your engine, your
engine oil level may be too low. You may need to add
oil.
See “Engine Oil” in the Index.
NOTICE:
The oil level monitoring system only checks the
oil level when you are starting your engine.
It
does not keep monitoring the level once your
engine
is running. Also, the oil level check only
works when the engine has been turned
off long
enough for the oil to drain back into the oil pan.
2-89

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When
you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
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 fiist 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?

Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a
hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your
parking brake, and then shift to
PARK (P) for an
automatic transmission, or
REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on
this. Things that are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, drive belts, cooling
system and brake adjustment. Each of these is covered
in
this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review
this information before you start your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.
4-38

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Cooling Engine Fans
A CAUTION: I
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.
I I
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
5-17

If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans
are running. If the
engine is overheating, both fans should be running.
If
they aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD add a 50150 mixture of clean water
(preferably distilled) and DEX-COOL@ engine coolant
at the coolant recovery tank. (See “Engine Coolant” in
the Index for more information.)
a CAUTION:
-1
Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch
fire and you or others could be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
