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(s), 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

fight.
-
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.
4-38

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However,
you can use SAE 5W-30 if it's going
to be colder
than 60 "F (1 6" C) before your next oil
change. When it's very cold, you should use SAE
5W-30. These numbers on an oil container show its
viscosity,
or thickness. Do not use other viscosity oils,
such as
SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
"Starburst" symbol. Failure to use the
recommended
oil can result in engine damage
not covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29"C), consider using either an SAE 5W-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting
and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. Your dealer is ready to
advise if you
think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:

Most tsips are less than 5 to 10 miles (8 to 16 lun).
This is particularly important when outside
temperatures are below freezing.
Most
trips include extensive idling (such as fiequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle
is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner.
If any one of these is true for your
vehicle,
then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs
first.
6-16

If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your
skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your
skin and nails with soap and
water, or a
good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and
disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from
the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle
it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for
help.
Air Cleaner
The air cleaner and filter are on the driver’s side of the
engine compartment.
1. Remove the screws on the air cleaner housing cover.
6-17

2. Remove the air intake hose that is fitted over the
throttle body by pulling the hose upward and away
from the throttle body which is located near the top
of the engine.
3. Disconnect the electrical
connector which is
attached to the air
temperature sensor
located in the hose.
This will allow you to
lift
the rear portion of
the air cleaner.
4. After detaching the hose from the throttle body and
disconnecting the electrical connector, pull back the
entire rear portion of the air cleaner by pulling
upward and rearward.
5. Replace the air filter.
6. Reinstall the rear section of the air cleaner.
7. Reconnect the electrical connector.
8. Reattach the air intake hose.
Refer to the Maintenance Schedule
to determine when to
replace the
air filter.
See “Scheduled Maintenance Services” in the Index.

How to Check and Add Oil
Check oil only when the engine is cold. Allow the
engine
to cool two to three hours after running.
If you remove the supercharger oil €ill plug while
the engine
is hot, pressure may cause hot oil to
blow out
of the oil fill hole. You may be burned.
Do not remove the plug until the engine cools.
1. Clean the area around the oil fill plug before
2. Remove the oil fill plug using a 3/16 inch
3. The oil level is correct when it just reaches the
bottom of the threads of the inspection hole.
4. Replace the oil plug with the O-ring in place.

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.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:
0 In heavy city traflic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
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 dealership
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.

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 OOO to 13 OOO km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or wheels.
See “When It’s Time for New Tires” and “Wheel
Replacement” later in
this section for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled Maintenance Services” in the Index for scheduled
rotation intervals.

Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown
on the
Tire-Loading Information label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque” in the Index.
A CAUTION:
Rust or dirt on a wheel, or on 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 do this; but be
sure to use a scraper or wire brush later,
if you
need to, to get all the rust or dirt
off. (See
“Changing a Flat Tire” in the Index.)

When rotating your tires, always use the correct rotation
pattern shown here.

I 7-37 Part D: Recommended Fluids and Lubricants
7-39 Part E: Maintenance Record

How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what to have done and how often. Some
of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
A CAUTION:
I
Performing maintenance work on a vehicle can
be dangerous. In trying to
do some jobs, you can
be seriously injured.
Do your own maintenance
work only
if you have the required know-how
and the proper tools and equipment for the job.
If you have any doubt, have a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information. See “Service and Owner Publications”
in
the Index.
“Part B: Owner Checks and Services” tells you what
should be checked and when. It
also explains what you
can easily do to help keep your vehicle in
good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your dealer’s service department
or another qualified service center should
perform.
“Part D: Recommended Fluids and Lubricants” lists
some recommended products to help keep your vehicle
properly maintained. These products, or their equivalents, should be used whether you do the work
yourself or have it done.
“Part E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure
to write it down in this part. This will help you
determine when your next maintenance should be done.
In addition, it is
a good idea to keep your maintenance
receipts. They may be needed
to qualify your vehicle for
warranty repairs.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times a week.
Or you may drive
long distances all the time in very hot, dusty weather.
You
may use your vehicle in making deliveries. Or
you may drive it to work, to do errands or in many
other ways.
Because
of all the different ways people use their
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than you’ll find
in the schedules in this section. So please read this
section and note how you drive. If you have any
questions on how to keep your vehicle in good
condition, see your Pontiac dealer.
This part tells you the maintenance services you should
have done and when you should schedule them. If you
go to your dealer for your service needs, you’ll know
that GM-trained
and supported service people will
perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in
Part D. Make sure whoever services your vehicle uses
these. All parts should be replaced and all necessary
repairs done before you or anyone else drives the vehicle.
These schedules are for vehicles that:
0 carry passengers and cargo within recommended
limits.
You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle’’ in the Index.
are driven on reasonable road surfaces within legal
driving
limits.
0 use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how
to decide which
schedule to follow:
