Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
whiie you:
Start your engine:
Shift into a gear: and
Release the parking brake.
3,. 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, belt. 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.

This vehicle has a clutched engine cooling fan. When
the clutch
is engaged, the fan spins faster to provide
more air
to cool the engine. In most everyday driving
conditions, the clutch
is not engaged. This improves
fuel economy and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or high outside
temperatures. the fan speed increases when the clutch
engages.
So you may hear an increase in fan noise. This
is normal and should
not be mistaken as the
transmission slipping or making extra shifts.
It is merely
the cooling system functioning properly. The
fa11 will
slow down when additional cooling is not required and
the clutch disengages.
You may also hear this fan noise when you start the
engine.
It will go away as the fan clutch disengages.
If a Tire Goes Flat
It'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 tire, it's much Inore likely to leak out slowly.
But if you should ever have ;I "blowout." here are a few
tips about what to expect and what to do:
If a front tire fails. the flat tire will create a 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. and then gently brake to
a stop well out of the traffic lane.
A rear blowout. particularly on a curve. acts much like a
skid and may require the same correction you'd use in a
skid. In any rear blowout. remove your foot from the
xcelerator pedal. Get the \,chicle under control by
steering the way you want the vehicle to go. It may be
\.cry bunlpy and noisy. but you can still steer. Gently
brake
to a stop -- well off the road if possible.

Downloaded from www.Manualslib.com manuals search engine How to Check
Because this operation can be a little difficult, you may
choose
to have this done at your GM 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:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F (83OC
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
(IOOC). If it's colder than 50°F (IOOC), 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.

Downloaded from www.Manualslib.com manuals search engine 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). Don’t overfill.
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; then flip the handle
down
to lock the dipstick in place.
I NOTICE:
~ ~~ ~
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than
DEXRON-111
is not covered by your new vehicle warranty.
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; then flip the handle
down
to lock the dipstick in place.

Downloaded from www.Manualslib.com manuals search engine I A CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires of different sizes may
also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for use on
your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by
the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only
to vehicles sold in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires.
The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters
of 10 to 12 inches (25 to 30 cm),
or
to some lirnited-production tires.
While the tires available
on General Motors passenger
cars and light trucks may vary with respect
to these
grades, they must also conform
to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon
the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences
in
road characteristics and climate.

Downloaded from www.Manualslib.com manuals search engine Traction -- A, B, C
The traction sades, from highest to lowesr. are A. B. and
C, and they represent the tire's ability to stop on wet
pavement
as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction per-fornmance.
Warning: The traction grade assigned to
this tire is based
on braking (straight ahead) traction tests and does not
include cornering (turning) traction.
Temperature -- A, B, C
The temperature grades are A (the highest). B, and C.
representing the tire's resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on
a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life.
and excessive temperature can lead to sudden tire
failure. The grade
C corresponds to a level of
performance which all passenger car tires must meet
under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law. Warning: The
temperature grade for this tire
is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately
or in combination.
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are
not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or
the other. the alipment
may need to be reset. If you notice your vehicle
vibrating when driving
on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent. cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel.
wheel bolts and wheel
nuts should be replaced. If the
wheel leaks air. replace
it (except some aluminum
wheels. which can sometimes be repaired).
See your
GM dealer if any of these conditions exist.
Your dealer
will know the kind of wheel you need.
