When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
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, 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
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

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 (+) to (-), or
you’ll get a short that would damage the battery and
maybe other
parts, too.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
COLD mark, add a 50/50 mixture of clean
water (preferably distilled) and a proper antifreeze at the
coolant recovery tank. (See “Engine Coolant”
in the
Index for more information about the proper coolant
mix.)

Gasolines for Cleaner Air Fuels in Foreign Countries
Your use of gasoline with deposit control additives will
help prevent deposits from forming in your engine and
fuel system. That helps keep your engine in tune and
your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for
cleaner air.
Many gasolines are now blended with oxygenates. General Motors recommends that you use gasolines with
these blending materials, such as MTBE and ethanol. By
doing
so, you can help clean the air, especially in those
parts of the country that have high carbon monoxide
levels.
In addition, some gasoline suppliers
are now producing
reformulated gasolines. These gasolines
are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts
of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain deposit control additives and
oxygenates, and if they have been reformulated to
reduce vehicle emissions.
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode, and
your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that means costly repairs that 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
Vehicle Identification Number
(VIN).

You should check your engine
oil level regularly; this is

to check your engine oil every time you

Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the upper mark, then you’ll need
to add some oil. But you must use the right kind. This
part explains what kind of oil to use. For crankcase
capacity, see “Capacities
and Specifications” in the
Index.
NOTICE:
Don’t add too much oil. If your engine has
so much oil that the oiI level gets above the
cross-hatched area that shows the proper
operating range,
your engine could be damaged.

If the air cleaner is off, a backfire can cause a
damaging
engine fire. And, dirt can easily get
into your engine, which will damage
it. Always
have the
air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level
is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change your fluid. See “Scheduled Maintenance Services” in
the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Pontiac dealer Service
Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could
come out and fall on hot engine parts
or exhaust system parts, starting
a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.

Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get
the vehicle warmed up by driving about 15 miles (24 km)
when outside temperatures are above 50°F (10°C). If it's
colder
than 50°F ( 1O"C), you may have to drive longer.

3. Check both sides of the dipstick, and read the lower
level. The fluid level must be in the cross-hatched
area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it
to the proper level.
It doesn’t take much fluid, generally less than a pint
(OSL). Don’t overfiZ1. We recommend you use only fluid
labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transaxle. Damage
caused by fluid other than
DEXRON@-III is not covered
by your new vehicle warranty.
After adding fluid, recheck the fluid level as
