Downloaded from www.Manualslib.com manuals search engine After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires and exhaust system
for damage. Also, check the fuel lines and cooling
system for any leakage.
Your vehicle will require more frequent service due to
off-road use. Refer to the Maintenance Schedule for
additional information.
Driving at Night
I
Night driving is more dangerous than day driving. One
reason is that
some drivers are likely to be impaired -- by
alcohol
or drugs, with night vision problems, or by fatigue.

Downloaded from www.Manualslib.com manuals search engine 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 light duty trailer wiring is a six-wire harness
assembly. The heavy duty trailer wiring is an eight-wire
harness assembly. The harnesses are stored under
the
vehicle, along the passenger-side frame crossmember on
two-door vehicles or on the driver’s side corner frame
crossmember
on four-door vehicles. The heavy duty
trailer wiring has a 30-amp feed wire with an inline fuse
located by the junction block. See “Fuses and Circuit
Breakers” in
the Index. Both harnesses have no
connector and should be wired
by a qualified electrical technician. The technician can
use the following color code chart when connecting the
wiring harness
to your trailer.

DARK BLUE: Use for electric trailer brakes or
auxiliary wiring.
RED: Use for battery charging; it connects to the
starter solenoid (eight-wire harness
only).
LIGHT GREEN: Back-up lamps (eight-wire
harness only).
BROWN: Taillamps and parking lamps.
YELLOW Left stoplamp and turn signal.
DARK GREEN: Right stoplamp and turn signal.
WHITE (Heavy Gage): Ground wire.
WHITE (Light Gage): Auxiliary stoplamp.
Securely 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.

To remove the air cleaner, remove the wing nuts that hold
the cover on. Remove the cover and
lift out the air filter.
Insert a new air filter, then replace the air cleaner cover.
Tighten the wing nuts
to hold the cover in place.
Refer to the Maintenance Schedule
to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the Index.
A CAUTION:
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.
I 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.

Downloaded from www.Manualslib.com manuals search engine .. 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 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If 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.
I 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°F (32°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
(82°C to 93°C).

then
pull it back out again,
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.
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 a
pint. Don ’t overfill. We recommend you use only fluid
labeled DEXR0N’-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.
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.

The proper fluid should be added if the level does not
reach the bottom
of the diaphragm when it’s in place in
the reservoir. See the instructions on the reservoir cap.

How to Check Lubricant
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”

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.

Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
The following explains your cooling system and how
to add coolant when
it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your vehicle will:
0 Give freezing protection down to -34°F (-37 “C).
Give boiling protection up to 265 “F (129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.

NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months whichever
occurs first.
