Towing a Trailer
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well Ð or even
at all. You and your passengers could be
seriously injured. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only if
you have followed all the steps in this section.
Ask your dealer for advice and information
about towing a trailer with your vehicle.Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what
the vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº that
appears later in this section. But trailering is different
than just driving your vehicle by itself. Trailering means
changes in handling, acceleration, braking, durability
and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That's the reason for this part. In it are many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully before
you pull a trailer.
Load-pulling components such as the engine, transaxle,
wheel assemblies and tires are forced to work harder
against the drag of the added weight. The engine
is required to operate at relatively higher speeds and
under greater loads, generating extra heat. What's more,
the trailer adds considerably to wind resistance,
increasing the pulling requirements.

When to Add Engine Oil
If the oil is at or below the hole at the tip of the dipstick,
then you will need to add at least one quart of oil.
But you must use the right kind. This section explains
what kind of oil to use. For engine oil crankcase
capacity, see
Capacities and Speci®cations on
page 5-101.
Notice:Don't add too much oil. If your engine has
so much oil that the oil level gets above the
upper mark that shows the proper operating range,
your engine could be damaged.
See
Engine Compartment Overview on page 5-12for
the location of the engine oil ®ll cap.
Be sure to add enough oil to put the level somewhere in
the proper operating range. Push the dipstick all the
way back in when you are through.
5-17

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.

All-Wheel Drive
If you have an all-wheel-drive vehicle, be sure to
perform the lubricant checks described in this section.
However, it has two additional systems that need
lubrication.
Transfer Case (Power Transfer Unit)
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. SeePart C: Periodic
MaintenanceInspections on page 6-24.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the ®ller plug hole,
you'll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the ®ller plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeePart D: Recommended
Fluids and Lubricants on page 6-26.
Carrier Assembly-Differential
(Rear Drive Module)
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
Part A: Scheduled Maintenance Services on page 6-4.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the ®ller plug hole,
you'll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the ®ller plug hole.
A ¯uid loss could indicate a problem; check and have it
repaired, if needed.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeePart D: Recommended
Fluids and Lubricants on page 6-26.

Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your dealer. For the type of bulb to use,
see
Replacement Bulbs on page 5-59.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas inside
and can burst if you drop or scratch the bulb.
You or others could be injured. Be sure to read
and follow the instructions on the bulb
package.

A. Tire Size
B. Department of Transportation (DOT)
C. Tire Identi®cation Number (TIN)
D. Tire Ply Material
E. Uniform Tire Quality Grading (UTQG)
F. Maximum Cold In¯ation Load Limit
Tire Size:The tire size is a combination of letters and
numbers used to de®ne a particular tire's width,
height, aspect ratio, construction type and service
description. See the ªTire Sizeº illustration later in this
section for more detail.
Department of Transportation (DOT):The
Department of Transportation (DOT) code indicates that
the tire is in compliance with the U.S. Department of
Transportation Motor Vehicle Safety Standards.Tire Identi®cation Number (TIN):The letters and
numbers following DOT code are the Tire Identi®cation
Number (TIN). The TIN shows the manufacturer and
plant code, tire size, and date the tire was manufactured.
The TIN is molded onto both sides of the tire.
Tire Ply Material:The type of cord and number of plies
in the sidewall and under the tread.
Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires based on
three performance factors: treadwear, traction and
temperature resistance. For more information see
Uniform Tire Quality Grading on page 5-72.
Maximum Cold In¯ation Load Limit:Maximum load
that can be carried and the maximum pressure
needed to support that load. For information on
recommended tire pressure see
In¯ation Ð Tire
Pressure on page 5-67andLoading Your Vehicle on
page 4-32.
