Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle ¯uid
level is when the engine oil is changed.
Check the ¯uid in the transaxle and differential every
30,000 miles (50 000 km). Change the ¯uid every
60,000 miles (100 000 km) if the vehicle is mainly driven
under one or more of these conditions:
·In heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) or higher.
·In hilly or mountainous terrain.
·When doing frequent trailer towing.
·Uses such as found in taxi, police or delivery
service.
See
Part A: Scheduled Maintenance Services on
page 6-4.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at the 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.
Notice:Too much or too little ¯uid can damage
your transaxle. Too much can mean that some of the
¯uid could come out and fall on hot engine or
exhaust system parts, starting a ®re. Too little ¯uid
could cause the transaxle to overheat. Be sure
to get an accurate reading if you check your
transaxle ¯uid.
Wait at least 30 minutes before checking the transaxle
¯uid level if you have been driving:
·When outside temperatures are above 90ÉF (32ÉC).
·At high speed for quite a while.
·In heavy traffic ± especially in hot weather.
·While pulling a trailer.
To get the right reading, the ¯uid should be at
normal operating temperature, which is 158ÉF to 176ÉF
(70ÉC to 80ÉC).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50ÉF
(10ÉC). If it's colder than 50ÉF (10ÉC), you may have to
drive longer.

How to Add Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle ¯uid to use. See
Part D: Recommended Fluids and Lubricants
on page 6-26.
If the ¯uid level is low, add only enough of the proper
¯uid to bring the level into the area between dimples on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough ¯uid at the
dipstick hole to bring it to the proper level.
It doesn't take much ¯uid, generally less than
one pint (0.5 L).
Don't over®ll.
Notice:
We recommend you use only ¯uid labeled
T-IV Automatic Transmission Fluid because ¯uid
with that label is made especially for your automatic
transaxle. Damage caused by ¯uid other than T-IV
Automatic Transmission ¯uid is not covered by your
new vehicle warranty. See ªRecommended Fluids
and Lubricantsº in the Index.
3. After adding ¯uid, recheck the ¯uid level as
described under ªHow to Checkº previously in
this section.
4. When the correct ¯uid level is obtained, push the
dipstick back in all the way; then press the tab
down to lock the dipstick in place.
Manual Transaxle Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the ¯uid in your manual transaxle
doesn't require changing.
How to Check
Because this operation can be 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.
Notice:Too much or too little ¯uid can damage
your transaxle. Too much can mean that some of the
¯uid could come out and fall on hot engine or
exhaust system parts, starting a ®re. Too little ¯uid
could cause the transaxle to overheat. Be sure
to get an accurate reading if you check your
transaxle ¯uid.
Check the ¯uid level only when your engine is off, the
vehicle is parked on a level place and the transaxle
is cool enough for you to rest your ®ngers on the
transaxle case.
5-25
When to Check and What to Use
Refer to the Maintenance
Schedule to determine
how often you should
check the ¯uid level in your
master cylinder reservoir
and for the proper
¯uid. See
Part B: Owner
Checks and Services
on page 6-19
andPart D:
Recommended Fluids
and Lubricants on
page 6-26
.
How to Check and Add Fluid
Check to make sure that the ¯uid level is at or above
the MIN mark. If the level is below the MIN mark,
see the instructions on the reservoir cap.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page 5-30.
A 50/50 mixture of clean, drinkable water and the proper
coolant will:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·Protect against rust and corrosion.
·Help keep the proper engine temperature.
·Let the warning lights and gages work as they
should.
5-27
What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half half coolant that meets GM
Speci®cation 1825-M, which won't damage aluminum
parts. You can also use a recycled coolant conforming to
GM Speci®cation 1825-M with a complete coolant
¯ush and re®ll. If you use this coolant mixture, you don't
need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn't get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and the proper coolant.
Notice:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice:If you use the proper coolant, you don't
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The vehicle must be on a
level surface. When your
engine is cold, the
coolant level should be at
LOW, or a little higher.
When your engine is warm,
the level should be up to
FULL, or a little higher.

Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a
car washing soap to clean exterior lamps and lenses.
Follow instructions under ªWashing Your Vehicle.º
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint ®nish. You can get GM-approved cleaning products
from your dealer. See
Vehicle Care/Appearance
Materials on page 5-95.
If your vehicle has a ªbasecoat/clearcoatº paint ®nish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat paint
®nish.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint ®nish may
dull the ®nish or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc.,
can damage your vehicle's ®nish if they remain
on painted surfaces. Wash the vehicle as soon aspossible. If necessary, use non-abrasive cleaners that
are marked safe for painted surfaces to remove
foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a
period of years. You can help to keep the paint ®nish
looking new by keeping your vehicle garaged or covered
whenever possible.
Windshield, Backglass and Wiper
Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade or
windshield.
Clean the outside of the windshield with a full-strength
glass cleaning liquid. The windshield is clean if beads do
not form when you rinse it with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by
wiping vigorously with a cloth soaked in full-strength
windshield washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties. See your
Warranty and Owner Assistance booklet or your dealer
for details.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended ¯uids and lubricants as prescribed in this
manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure
to follow scheduled maintenance may not be covered by
warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. Improper vehicle maintenance can
even affect the quality of the air we breathe. Improper
¯uid levels or the wrong tire in¯ation can increase
the level of emissions from your vehicle. To help protect
our environment, and to keep your vehicle in good
condition, be sure to maintain your vehicle properly.

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:
Short Trip/City De®nition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
·Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
·Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
·You frequently tow a trailer or use a carrier on top
of your vehicle.
·If the vehicle is used for delivery service, police,
taxi or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km):Engine Oil and Filter
Change (or 3 months, whichever occurs ®rst).
Every 6,000 Miles (10 000 km):Tire Rotation. Engine
Air Cleaner Filter Inspection, if driving in dusty
conditions.
Every 15,000 Miles (25 000 km):Passenger
Compartment Air Filter Replacement. Transfer Case
Fluid Change (when trailer towing). Rear Differential
Fluid Change (when trailer towing).
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Fuel Tank, Cap, Cap Gasket and
Lines Inspection (or every 24 months, whichever occurs
®rst). Automatic Transaxle Check. Manual Transaxle
Fluid Change (severe conditions only) (or every
24 months, whichever occurs ®rst). Cooling System
Service (or every 24 months, whichever occurs ®rst).
Every 60,000 Miles (100 000 km):Automatic Transaxle
Fluid Change (severe conditions only). Valve Clearance
Inspection, adjust if necessary (or every 48 months,
whichever occurs ®rst).

Replacement.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
Long Trip/Highway De®nition
Follow this scheduled maintenanceonlyif none of the
conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule if the
vehicle is used for trailer towing, driven in a dusty area
or used off paved roads. Use the Short Trip/City
schedule for these conditions
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break down
slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km):Engine Oil and Filter
Change (or every 12 months, whichever occurs
®rst). Tire Rotation.Every 15,000 Miles (25 000 km):Passenger
