If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can
make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These
parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know
is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a
steep or long kill.
Coasting downhill! in NEUTRAL (N) or with
the ignition
off is dangerous. Your brakes will
have to do all the work of slowing
down. They
could get
so hot that they wouldn’t work well.
You would then have poor braking or even
none
going down a hill. You c’ould crash. Always have
your engine running and your vehicle in gear
when you! go downhill.

down
a hill. You could crash. Shift down to let
your engine assist your brakes on a steep

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. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmiss’ion.
2. Have someone place chocks under the trailer wheels.
3, When the wheel C~OGBS are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your parking
brake, and then shift to
PARK (P), or REVERSE (R)
for a manual transmission.
5. 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:
Start your engine;
Shift into a gear; and
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 transmission fluid (don’t
overfill), engine oil, axle lubricant, belts, 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.

Section 6 Service and Appearance Care
Here you will find information about the care of your Pontiac. This section begins with service and fuel information,
and then it shows how to check imDortant fluid and lubricant levels. There is also technical information about your I
vehicle, and a part devoted to its appearance care.

If you have the 5.7L LT1 engine (with the WS6 option),
your air cleaner will be located over the radiator near the
front
of the engine.
To remove the filter, remove the screws (located on the
rear edge of the air cleaner), lift the air cleaner and
remove
the filter.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every 15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90” F (32” C) or higher.
0 Uses such as high
performance operation.
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, change the fluid and filter every
100,000 miles ( 166 000 km),
See “Scheduled Maintenance Services” in the Index.

HQW 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
transmission.
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
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
When outside temperatures are above 90 OF (32 O 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 (82OC to 93°C).
Checking Transmission Fluid Hot
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 (lO"C), drive the
vehicle in DRIVE (D) until the engine temperature gage
moves and then remains steady for
10 minutes. Then
follow the hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine off and is d
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F (10OC) or
more. If it's colder than
50°F (lO"C), you may have to
idle the engine longer. Should the fluid level be low
during a cold check,
you must perform a hot check
before adding fluid. This will give you a more accurate
reading
of the fluid level.

in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in
PARK (P).
Let the engine run at idle for three minutes or more.
Then, without shutting off the engine, follow these steps:

3. Check both sides of the dipstick, and read the lower
level, The fluid level must be in the
COLD area for a
cold check or in the
HOT area or ‘cross-hatched area
for a hot check.
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 transmission fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check is used only as a reference.) If
the fluid level
is low, add only enough of the proper fluid
to bring the level
up to the HOT area for a hot check. It
doesn’t take much fluid, generally
less than one pint
(0.5 L). Dm ’t ove 111. We reconramend you use only fluid
labeled
BEXRON -111, because fluid with that label is
made especially for your automatic transmission, Damage
caused by fluid other than DEXRON-I11 is not covered
by your
new vehicle warranty.
?l
After adding fluid, recheck the fluid level as
described under
“How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.

Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual
transmission 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 fluid can damage your
transmission.
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
I transmission fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission is
cool
enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom
of the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level
is low, add more
fluid as described in the next steps.
How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up to the bottom of
the filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
