LA CAUTION: I
-1 -
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the
engine, it could lose all coolant. That could
cause an engine
fire, and you could be burned.
Get
any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling 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 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge
tank pressure cap, is
cool before you do it. (See “Engine Coolant” in the
Index for more information.)
’ /$ CAUTION:
-
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
cap to cool if you ever have to turn the
pressure cap.
5-18

4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can
feel the upper
radiator hose getting hot. Watch out for the engine
cooling
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 mixture to the coolant surge tank
until the level reaches
FULL COLD, or just above
the small cylinder
at the base of the opening.
5. Then replace the pressure cap. Be sure the pressure
cap is tight.
Check the level in the surge
tank when the cooling
system has cooled down.
If the coolant isn’t at the
proper level, repeat Steps
1 to 3 and reinstall the
pressure cap or see your dealer.

A CAUTION: nl
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, the proper replacement parts
and tools before you attempt any vehicle
maintenance
task.
0 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.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around
it. This may cause wind noise
and affect windshield washer performance. Check with your dealer before adding equipment to
the outside of
your vehicle.
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
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.
6-3

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
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 your 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 of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be aEected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Pontiac dealer
for service.
To provide cleaner air, all gasolines in the United States
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.
I 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.

Filling a Portable Fuel Container
Checking Things Under the Hood
I A CAUTION:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You
can
be badly burned and your vehicle damaged if this
occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup
bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline.
‘ A CAUTION:
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.
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 be burned.
Be careful not to drop or spill
things that
will burn onto a hot engine.

Engine Oil
If your vehicle is equipped
with the
3 100 engine,
there is a CHECK
OIL CHECK
OIL
light in your instrument
panel cluster.
If the CHECK
OIL light on the instrument panel comes
on, it means you need to check your engine oil level
right away. For more information,
see “Check Oil
Light”
in the Index. You should check your engine oil
level regularly; this is an added reminder.
It’s a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be
warm and the vehicle must be on level ground.
2.4L Engine

c
3100 Engine
The engine oil dipstick handle is yellow. The dipstick on
the
2.4L engine is located at the rear of the engine. The
dipstick on the
3 100 engine is located on the front of the
engine, behind the fan.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.

Air Cleaner
The air cleaner is located on the driver’s side of the
engine compartment.
To check or replace the air filter:
1. Remove the screws that hold the cover on.
2. Lift off the cover.
3. Reinstall the air cleaner filter and replace the
cover tightly. Refer to the Maintenance Schedule to determine
when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
A CAUTION:
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the
air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires,
you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the
air cleaner off.
NOTICE:
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.
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 traffic where the outside temperature
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
regularly reaches
90°F (32°C) or
higher.
0 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.
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.
