1993 PONTIAC GRAND-PRIX change wheel

Do not tow a trailer if your vehicle is
equipped with a 3.4L (VIN Code X)
engine and a manual transaxle.
Your Pontiac can tow a trailer if it is
equipped with a
3.1L (VIN Code T)
engine or a 3.4L (VIN Code X) engine
and an automatic transaxle, and proper
trailer towing equipment.
To identify
what the vehicle trailering capacity is
for your vehicle, you should read the
information in
Weight of the Trailer
that appears later in this section. But
trailering is different than just driving
your vehicle by itself. Trailering means
changes in handling, durability, and fuel
economy. Successful, safe trailering
takes correct equipment, and it has to
be used properly.
That’s the reason for this section. In it
are many time-tested, important
trailering tips and safety rules. Many of these
are important
for your safety and
that of your passengers.
So please read
this section carefully before you pull a
trailer. Load-pulling components such
as the engine, transaxle, wheel
assemblies, and tires are forced to work
harder against the drag of the added
weight. The engine is required to
operate at relatively higher speeds and
under greater loads, generating extra
heat. What’s more, the trailer adds
considerably to wind resistance,
increasing the pulling requirements.
All of that means changes in:
Handling
Durability
Fuel economy
If You Do Decide to Pull a Trailer
If you do, here are some important
points.
There are many different laws having
to do with trailering. Make
sure your
rig will be legal, not
only where you
live but also where you’ll be driving. A
good source for this information can
be state or provincial police.
Consider using a sway control. You
can ask a hitch dealer about sway
control.
Don’t tow a trailer at all during the
first
500 miles (800 km) your new
vehicle is driven. Your engine, axle or
other parts could be damaged.

Towing Your Pontiac
Try to have a GM dealer or a
professional towing service tow your
Pontiac. The usual towing equipment is:
(A) Sling-type tow truck
(B) Wheel-lift tow truck
(C) Car carrier

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:
That your vehicle cannot be towed

It’s unusual for a tire to “blow out”
while you’re driving, especially if
you
maintain your tires properly. If air goes
out
of a tire, it’s much more likely to
leak out slowly. But if you should ever
have
a “blowout,” here are a few tips
about what to expect
and what to do:
If
a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
2010
A rear blowout, particularly cm a curve,
acts
much like a skid and may require
the same correction
you’d use in a skid.
In any rear blowout, remove pur bot
from the accelerator pedal. G,et the
vehicle under control by steering the
way
you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer, Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the next se’ction
shows how
to use your jacking
equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn
on your hazard
warning flashers.
A Changing a tire can cause an
injury. The vehicle can
slip off
the jack and roll over you or other
people.
You and they could be badly
injured.

CAUTION
(Continued)
1. Set the parking brake firmly.
2. Put the shift lever in P (Park)
3. Shift a manual transaxle to
1 (First) or R (Reverse).
4. Turn off the engine.
To be even more certain the vehicle
won’t move, you can put chocks at
the front and rear of the tire farthest
away from the one being changed.
That would be the tire on the other
side of the vehicle, at the opposite
end.

Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern.
If you don't have P245/50ZR16 size
tires, use the rotation pattern shown
above for your size tires.
256
If you have P245/510ZR16 size tires,
they must roll
in a certain 'direction for
the best overall performance. The
direction is shown
by an arrow on both
sidewalls. Because these tirles are
directional, they should be rotated
as
shown in the example above. These
tires should only be moved
from front
to rear and rear to front
on the same
side
of the vehicle.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown
on the Tire-Loading Information
label. Make certain that
all wheel nuts
are properly tightened. See the Index
under Wheel Nut Torque.
Rust or dirt on a wheel, or on
ri the parts to which it is
fastened, can make wheel nuts
become loose after a time. The
wheel could come off and cause an
accident. When you change a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency,
you
can use a cloth or a paper towel to

to get all the rust or dirt off. (See
