1998 PONTIAC GRAND PRIX service

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:

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?

Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack
of awareness, or whatever.
There is something about
an easy stretch of road with
the
same scenery, along with the hum of the tires on the
road, the drone of the engine, and the
rush of the wind
against the vehicle that can make you sleepy. Don’t let it \
happen
to you! If it does, your vehicle can leave the
road in
less than a second, and you could crash
and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview
mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

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;
0 Shift into a gear; and
0 Release the parking brake.
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 transaxle fluid (don’t overfill),
engine oil,
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.

Don't let the other end touch anything until the
next step. The other end
of the negative (-) cable

It goes to a heavy, unpainted, metal part on the engine of
the vehicle with the dead battery.
9. Attach the cable at least 18 inches (45 cm) away
from the dead battery, but
not near engine parts that
move. The electrical connection
is just as good
there, but the chance of sparks getting back to the
battery is much less.

If it won't start after a
few tries, it probably

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle.
See “Roadside Assistance” in
the Index.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting,
or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on the hazard
warning flashers.
When you call, tell the towing service:
0 That your vehicle cannot be towed from the front
0 That your vehicle has front-wheel drive.
The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
0 If there was an accident, what was damaged.

When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want to see them. A CAUTION:
To help avoid injury to you or others:
Never let passengers ride in a vehicle that is
Never tow faster than safe or posted speeds.
Never tow with damaged parts not
fully secured.
Never get under your vehicle after it has
been lifted
by the tow truck.
Always secure the vehicle on each side with
separate safety chains when towing
it.
Never use J-hooks. Use T-hooks instead. being towed.
5-9

A CAUTION:
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains
or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath
the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, have the ignition
turned
to the OFF position. The steering wheel should
be clamped
in a straight-ahead position, with a clamping
device designed for towing service.
Do not use the
vehicle’s steering column lock for this. The transaxle
should be
in PARK (P) and the parking
brake released.
Don’t have
your vehicle towed on the front wheels,
unless you must. If the vehicle must be towed on the
front wheels, be sure to follow the speed and distance
restrictions later
in this section or your transaxle will be
damaged. If these limitations must be exceeded, then the
front wheels have to be supported on a dolly.

NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
If your vehicle has the
3100 engine, see “Overheated Engine Protection
Operating Mode” in the Index.
If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (03)
or DRIVE (D).
If you no longer have the overheat warning, you
can
drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can
drive normally.
If the warning continues, pull over, stop, and park
your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of
the vehicle until it cools down. If your vehicle has the
3 100 engine, see “Overheated Engine Protection
Operating Mode” listed previously in this section.
You may decide not to lift the hood but to get service
help right away.
