It depends on how you plan to use
your rig. For example, speed, altitude,
road grades, outside temperature and
how much your vehicle is used to pull
a trailer are all important. And, it can
also depend on any special equipment
that you have on your vehicle.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total capacity
weight of your vehicle. The capacity
weight includes the curb weight of the
vehicle, any cargo you may carry in it
and the people who will be riding in
the vehicle. And if you will tow a
trailer, you must subtract the tongue
load from your vehlcle’s capacity
weight because your vehicle will be
carrying that weight, too. See
“Loading Your Vehicle” in the Index
for more information about your
vehicle’s maximum load capacity.
If you’re using a “dead-weight”
hitch, the trailer tongue (A) should weight
10% of the total loaded
trailer weight (B). If you have a
“weight-distributing” hitch, the
trailer tongue (A) should weigh 12%
of the total loaded trailer weight (B).
After you’ve loaded your trailer, weigh
the trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, you may be able
to get them right simply by moving
some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are
inflated to the limit for cold tires.
You’ll find these numbers
on the
Certification label at the rear edge of
the driver’s door or see “Loading
Your Vehicle
” in the Index. Then be
sure you don’t go over the
GVW limit
for your vehicle.

Hitches
It’s important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few
reasons why you’ll need the right hitch.
Here are some rules to follow:
0
0
Will you have to make any holes in
the body of your vehicle when you
install a trailer hitch? If you do, then
be sure to seal the holes later when
you remove the hitch. If you don’t
seal them, deadly carbon monoxide
(CO) from your exhaust can get into
your vehicle (see “Carbon Monoxide”
in the Index). Dirt and water can,
too.
The bumpers on your vehicle are not
intended for hitches.
Do not attach
rental hitches or other bumper-type
hitches to them. Use only a
frame-mounted hitch that does not
attach to the bumper.
Safety Chains
You should always attach chains between
your vehicle and your trailer. Cross the
safety chains under the tongue of the
trailer
so that the tongue will not drop to
the road if it becomes separated from the
hitch. Instructions about safety chains
may be provided by the hitch manufacturer or
by the trailer
, 1.
manufacturer. Follow the manufacturer’s
recommendation for attaching safety
chains. Always leave just enough slack
so
you can turn with your rig. And, never
allow safety chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000
pounds (450 kg) loaded, then it needs its
own brakes
- and they must be adequate.
Be sure to read and follow the instructions
for the trailer brakes
so you’ll be able to
install, adjust and maintain them properly.
Because you have anti-lock brakes, do not
try to tap into your vehicle’s brake
system. If
YOU do, both brake systems
won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount
of experience. Before setting out for the
open road, you’ll want to get to know
your rig. Acquaint yourself with the feel
of handling and braking with the added
weight
of the trailer. And always keep in
mind that ’the vehicle you are driving is
now a good deal longer and not nearly as
responsive
as your vehicle is by itself. Before you
start, check the trailer hitch
and platform, safety chains, electrical
connector, lights, tires and mirror
adjustment. If
the trailer has electric
brakes,
start your vehicle and trailer
moving and then apply the trailer brake
controller by hand to be sure the brakes
are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to
be sure that the load is secure,. and that
the lights and any trailer brakes are still
working.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer.,,This can
help
you avoid situations that’.require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up
ahead when you’re towing a trailer. And,
because you’re a good deal longer, you’ll
need to go much farther beyond the
passed vehicle before you can return to
your lane.

If a Tire Goes Flat
[t’s unusual for a tire to “blow out” while
you’re driving, especially
if you maintain
your tires properly. If air goes out of a
;ire, it’s much more likely to leak out
jlowly. But if you should ever have a
‘blowout,” here are a few tips about what
:o expect and what to do:
[fa front tire fails, the
flat tire will create
3 drag that pulls the vehicle toward that
side. Take your foot off the accelerator
pedal and grip the steering wheel firmly.
Steer to maintain lane position,
then
gently brake to a stop well out of the
traffic lane.
A rear blowout, particularly on a curve,
acts much like a
slud and may require the
same correction you’d use in a skid. In
any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle
under control by steering the way you
want the vehicle to go.
It may be very
bumpy and noisy, but you can still steer.
Gently brake to a stop, well
off the road
if possible.
[f a tire goes flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.

Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 kPa). After installing the
compact spare on your vehicle, you
should stop as soon as possible and make
sure your spare tire is correctly inflated.
The compact spare is made to perform
well at posted speed limits for distances
up to
3,000 miles (5 000 km), so you can
finish your trip and have your full-size
tire repaired or replaced where you want.
Of course, it’s best to replace your spare
with
a full-size tire as soon as you can.
Your spare will last longer and be in
good shape in case you need it again.
. . .I80
NOTICE:
If the compact spare is used as a rear
tire, do not drive faster than
50 mph
(80 km/h). Damage to the rear axle
may occur if the compact spare
is
driven faster than 50 mph (80 km/h).
This speed limitation does not apply
when the compact spare is used as a
front tire.
NOTICE:
Don’t take your compact spare
through an automatic car wash with
guide rails. The compact spare can
get caught on the rails. That can
damage the tire and wheel, and
maybe other parts of your vehicle.
Don’t use your compact spare on some
other vehicle.
And don’t mix your compact spare or
wheel with other wheels or tires. They
won’t fit. Keep your spare and its wheel
together.
NOTICE:
Tire chains won’t fit your compact
spare. Using them will damage your
vehicle and destroy the chains too.
Don’t use tire chains on your
compact spare.
H Zf You’re Stuck: Zn
Sand, Mud, Zce or
Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method known as “rocking” can hell
you get out when you’re stuck, but you
must use caution.
1
?
ProCarManuals.com

NOTICE:
Spinning your wheels can destroy
parts of your vehicle as well as the
tires.
If you spin the wheels too fast
while shifting your transmission back
and forth, you can destroy your trans-
mission.
Rocking your vehicle to get it out:
First, turn your steering wheel left and
right. That will clear the area around your
front wheels. If your vehicle has traction
control, you should
turn the system off.
(See “Traction Control System” in the
Index.) Then shift back and forth’ between
“R’ (Reverse) and a forward gear (or with
a manual transmission, between First or
Second gear and Reverse), spinning the
wheels as little as possible. Release the
accelerator pedal while you shift, and
press lightly on the accelerator pedal
when the transmission is in gear.
If that
doesn’t get you out after a few tries,
you
may need to be towed out. If you:do need
to be towed out, see “Towing
Yow
Vehicle” in the Index. .’

What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid - such as Delco-
Supreme ll@
(GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the
brake fluid reservoir cap before
removing it.
NOTICE:
Don’t let someone put in the
wrong kind of fluid. For example,
just
a few drops of mineral-based
oil, such as engine oil, in your
brake system can damage brake
system parts
so badly that they’ll
have to be replaced.
Brake fluid can damage paint,
so
be careful not to spill brake fluid on your vehicle. If you
do, wash it
off immediately. See “Appearance
Care”
in the Index.
Brake Wear
Unless you have the four-wheel disc
brake option, your Pontiac has front disc
brakes and rear drum brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed. The
sound may come and
go or be heard all
the time your vehicle is moving (except
when you are pushing on the brake pedal
firmly).
I NOTICE:
I
Continuing to drive with worn-out
brake pads could result in costly
brake repair. Some driving conditions
or climates may
cause a brake squeal when the brakes are
first applied or lightly applied. This does
not mean something is wrong with your
brakes.
If you have rear drum brakes, they don’t
have wear indicators, but if you ever hear
a rear brake rubbing noise, have the rear
brake linings inspected. Also, the rear
brake drums should be removed and
inspected each time the tires are removed
for rotation or changing. When you have
the front brakes replaced, have
the rear
brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if there is a
rapid increase in pedal travel.
This could
be a sign
of brake trouble.
