engine and let it run until you can feel the upper
radiator hose
getting hot. Watch out for the engine fan,
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches FULL COLD, or just above
the small cylinder at the base of the opening.

If a Tire Goes Flat
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, and then gently ‘brake to
a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In my rear blowout, remove your foot from the
accelerator pedal. Get 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 a tire goes flat, the next part 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.
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.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an’automatic transaxle shift lever in
PARK
(P), or shift a manual transaxle to
FIRST (1) or REVERSE (R).
3. lbrn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks 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.

If You’re Stuck: In Sand,,Mud, Ice or
Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known a,s
“rocking” can help you get out when you’re stuck, but
you must use caution.
/d CAUTION:
If you your .es spin at high speed, they can
explode, and you or others could be injured. And,
the tran,saxle or other parts of the vehicle can
overheat.
That could cause an engine compartment
fire or other damage. When you’re stuck, spin the
wheels
as little as possible. Don’t spin the wheels
above35 mph
(55 kdh) as shown on the
speedqmeter. Spinning
your wheels can destroy
parts of your
vehicle as well
as the tires. If you spin the wheels
too fast while shifting your transaxle back and
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking y---r vehick ID get it out:
First, turn your steering wheel left and right. That will
clear the pea around your front wheels. If your vehicle
has the Enhanced Traction System, you should turn
the system
off. (See “Enhanced Traction System’’
in the Index.) Then shift back and forth between
REVERSE (R) and a forward gear
(or with a manual
transaxle, between FIRST
(1) or SECOND (2) and
REVERSE
(R)), spinning the wheels as little as
possible. Release the accelerator pedal
while you shift,
and press lightly on the accelerator pedal when the
transaxle is in gear.
If that doesn’t get you out after a
few tries, you may need to be towed out. If you do need
to be towe’d out, see “Towing Your Vehicle” in the
Index.

A 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, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If
you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher.
At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association
(AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and
emission control system protection compared to other
gasolines.
Be ,sure the posted octane
is at least 87. If the octane-is
less
than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knocking, your’engine needs service.
But don’t worry if you hear a little pinging noise when
you’re accelerating
or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on
the underhood tune-up label),
it is designed to operate
on fuels that meet California
specifications. If such fuels
are not available in states
adopting California
emissions standards, your vehicle
will operate satisfactorily
on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp
on
you instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized Pontiac dealer for diagnosis to determine the
cause of failure.
In the event it is determined that the
cause
sf the condition is the type of fuels used, repairs
may not be covered
by your warranty.

In Canada, some gasolines contain an octane enhancing additive called MMT.
If you use such fuels, your
emission control system performance may deteriorate and the malfunction indicator lamp on your instrument
panel may turn
on. If this happens, return to your
authorized
Pontiac dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel.
In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available
in your area to help clean the air. General
Motors recommends that you use these gasolines if they
comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline
or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company .that does business
in the
country where you’ll be driving.

advice. Just tell us where you’re going and give your

NOTICE:
If you need a new cap, b'e sure to get the right
type.
Your dealer can get one for you. If you get
the wrong type, it may not fit or have proper
venting, and your fuel tank and emissions system
might be
damaged.
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic
or rubber. You or others
could b'e burned. Be
careful not to drop or spill
things
that will burn onto a hot engine.
