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, 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.
Trailer Wiring Harness
The eight-wire harness, if you have one, is stored under
your vehicle along the rear frame crossmember.
It is
wrapped and bound with a plastic strap. The harness has
a 30-anlp battery feed and no connector, and you should
have a qualified electrical service person wire your
harness for you. Attach the harness
to the trailer, then
tape or strap
it to your vehicle’s frame rail. Be sure you
leave
it loose enough so the wiring doesn’t bend or
break, but not
so loose that it drags on the ground.
Store the harness
in its original place. Wrap the harness
together and tie
it neatly so it won’t be damaged.
The five-wire harness,
if you have one, is stored inside
the vehicle at the passenger side rear corner, behind the
jack. This should be wired by a qualified electrical
service person. It must be routed out
of your vehicle
between the rear door and the floor,
with enough of the
harness left on both sides
so that the trailer or the body
won’t pull
it.
Store the harness in its original place. Wrap the harness
together and tie
it neatly so it won’t be damaged.

If your vehicle has a 7.4L engine and air conditioning,
your vehicle will have a auxiliary engine fan
in addition
to the belt driven
fdn.
If your vehicle has air conditioning, the auxiliary
engine 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. Before closing
the hood, be sure
all the filler caps are
on properly.
Then
lift the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot
in the hood and
return the prop to
its retainer. Then just let the hood
down and close
it firmly.
Noise Control System
The following information relates to compliance with
Federal noise emission standards for vehicles with a
Gross Vehicle Weight Rating (GVWR) of more than
10,000 lbs. (4 536 kg). The Maintenance Schedule
booklet provides information on maintaining the noise
control system to minimize degradation of the noise
emission control system during the life of your vehicle.
The noise control system warranty is given
in your
Warranty booklet.
These standards apply only
to vehicles sold in the
United States.

b
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.
1 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 Transmission Fluid
7 ’ ~ n 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 50,000 miles
(83 000 km) if the vehicle’s GVWR is over 8,600 or
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.
0 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 your vehicle’s GVWR is not over 8,600 and 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 GM dealer
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.

How to Add Fluid Rear Axle
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
Add
tluid 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 a
pint (0.5 L). DOLJ ’t overfill. 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.
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
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the
bottom of the filler plug
hole,
you’ll need to add
some lubricant. Add
enough lubricant to raise
the level
to the bottom of
the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.

Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine cooling system. The thermoskt stops the
tlow of coolant through the radiator until the coolant
reaches
a preset temperature.
When you replace your thermostat,
an AC@ thermostat
is recommended.
Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
tluid unless you suspect there
is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten
it. Then remove the cap again
and
look at the fluid level on the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough fluid to bring
the level up to
the mark.
To prevent brake fluid contamination, never check or
fill
the power steering reservoir with the master cylinder
cover off.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
damage hoses and seals.

Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.
There
are only two reasons why the brake fluid level in the
reservoir might
go down. The first is that the brake fluid
lining wear. When new linings are put in, thc tluid levcl
2 wes down to an acceptable level during nonnal brake
c qoes back up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake
system fixed, since
a leak means that sooner or later your
brakes won't work well, or
won't work at all.
So, it isn't a good idea to "top off' your brake tluid.
Adding brake fluid won't correct a leak. If you add fluid
when your linings are worn, then
you'll have too much
fluid when you get new brake linings.
You should add
(or remove) brake fluid, as necessary, only when work is
done
on the brake hydraulic system.
A CAUTION
If you have too much brake fluid, it can spill on the
engine. The fluid
will burn if the engine is hot
enough. You
or others could be burned, and your
vehicle could
be damaged. Add brake fluid only
when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See "Periodic Maintenance
Inspections"
in the Index.
