Turn Signals When Towing a Trailer
The green arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps
will also flash, telling other
drivers you’re about to
turn, change lanes or stop.
When towing a trailer, the green arrows
on your ’.
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not.
It’s important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would
get hot and no longer work well.
On a long uphill grade, use the highest gear possible. If you
cannot maintain posted speeds, driving at a lower speed
may help avoid overheating your engine and bxmsaxle.
If you have a manual transaxle with FWTH (5) gear,
it’s better not to use
FIFTH (5) gear. Just drive in
FOURTH (4) gear (or- as vou need to, a lower gear).
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.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet, or into a gear for a manual transaxle.
Have someone place chocks under the trailer wheels. When the wheel chocks are in place, release the
regular brakes until the chocks absorb
the load.
Reapply the regular brakes. Then apply your
parking
brake, and then shift to PARK (P), or REVERSE (R)
for a manual transaxle.
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;
Shift into a gear; and
I. 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 ovel-fill),
engine oil, belt, 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 these sections before you start

6. Check that the jumper cables don’t have loose or
missing insulation, If they do, you could get a shock.
The vehicles could be damaged,
too.
Before you connect the cables, here are some basic
things you should
know. Positive (+) will go to
positive (+) and negative (-) will go to negative (-)
or a metal engine part.
Don’t connect positive (+) to negative (-) or you’ll
get a short that would damage the battery and maybe
other
parts, too.
Using
a match
near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
~ Be sure the battery has enough water. You don’t
need to add water
to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first. If you don’t, explosive gas could be
present.
Battery fluid contains acid that can burn
you.
Don’t get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately. Fans
or other moving engine
parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

~~~ ~
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be. burned.
Donst run the engine
if there is a leak. If you run
the engine, it could
lose all coolant. That coulld
cause an engine
fire, and you could be burned.

by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan is running. If the engine is
overheating, the fan should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
or above FULL COLD, add a 50150 mixture of
clean water (preferably distilled) and DEX-COOL
antifreeze at the coolant surge tank, but be sure the
cooling
system, including the coolant surge tank
pressure cap,
is COO^ before you do it, (See “Engine
Coolant” in the Index for more infomati .) - --
I
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the cap
when the cooling
system, including the coolant
surge tank pressure
cap, is hot. Wait for the
cooling system and coolant
surge tank pressure.

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.
You can also write us at the following address for
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.
Checking "'lings Under the Hood
r
An electric fan under the hood can start up and
injure
you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric
fan.
The following sections tell you how to check fluids,
lubricants and important parts underhood.
TO open the hood, first pull
