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 H-T--- ess
The light duty trailer wir is a six-wire harness
assembly. The optional 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 rear 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.

can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parlung brake firmly on both vehicles involved in
the procedure. Put an automatic transmission vehicle
in
PARK (P) and a manual transmission vehicle in
NEUTRAL (N).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter, or accessory power outlets, if you have this
option. Turn off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries. In addition, it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repair wouldn’t be covered
by
your warranty.
4. Open both hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
AUTION:
I
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded.
Use a flashlight if
you need more light.
Be sure the battery has enough water.
You don’t
need to add water to the ACDelco Freedom@
battery installed in every new
GM vehicle. But if
a battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take care
of that first.
If you don’t, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your
skin, flush the place with
water and get medical help immediately.

Downloaded from www.Manualslib.com manuals search engine Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle. See “Roadside Assistance”
in
the Index.
If your vehicle
has been changed since it was
factory-new by adding things like fog lamps, aero
skirting, or special tires and wheels, these instructions
may not be correct.
Before you do anything, turn
on the hazard
warning flashers.
When you call, tell the towing service:
Whether your vehicle has rear-wheel drive,
four-wheel drive or all-wheel drive.
The make, model and year of your vehicle.
Whether you can move the shift lever for the
transmission and
shift the transfer case, if you
have one.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know
that this manual contains these towing
instructions. The operator may want to see them.

Downloaded from www.Manualslib.com manuals search engine When your vehicle is being towed, have the ignition key
turned to the OFF position. The steering wheel should
be clamped in a straight-ahead position with
a clamping
device designed for towing service.
Do not use the
vehicle’s steering column lock for this. The transmission
should be in
NEUTRAL (N) and the transfer case, if you
have one, should be in 2HI. The parking brake should
be released.
If your vehicle has a floor-mounted shifter and no
electrical power, the electrical solenoid lock must be
overridden to shift from PARK
(P) to NEUTRAL (N).
Follow these steps:
1. Push the base of the shift lever boot forward with
your thumb.
2. Lift the boot and find the white solenoid lever.
3. Move the solenoid lever
toward the driver’s side
to unlock
it.
4. While holding the solenoid lever in the unlock
position, press
the shift lever button and shift into
NEUTRAL
(N).
5. Release the solenoid lever and snap the boot back
into place.
Don’t have your vehicle towed on the drive wheels
unless you must. If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later
in this section or your transmission will
be damaged. If these limitations must be exceeded, then
the drive wheels have to be supported on a dolly.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
0 Tow a trailer. See “Driving on Grades” in the Index.
If you get the overheat warning with no sign of steam,
try this for a minute
or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window
as necessary,
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- DRIVE (D) or THIRD (3) for
automatic transmissions. If you no
longer have
the overheat warning, you can
drive. Just
to be safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign
of steam, push the accelerator until
the engine speed
is about twice as fast as normal idle
speed. Bring the engine speed back to normal idle speed
after two or three minutes. Now see if the warning stops.
But then,
if you still have the warning, turn ofSthe
engine
and get everyone out of the vehicle until it
cools down.
You may decide not to
lift the hood but to get service
help right away.

this procedure if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows on the pressure cap line
up like this.
Engine Fan Noise
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 fan 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.

Downloaded from www.Manualslib.com manuals search engine 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 more likely to leak out slowly.
But if you should ever have a “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.
H 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
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.
If a tire goes flat, the
next part shows how to use your
jacking equipment to change
a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place.
Turn on your hazard
warning flashers.
Changing a tire can cause an injury, The vehicle
can slip
off the jack and roll over you or other
people.
You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in PARK
(P) or shift a manual
transmission
to FIRST (1) or
REVERSE (R).
3. Thrn off the engine.
4. Put the wheel blocks at the front and
rear of the tire farthest away from the
one being changed. That would
be the
tire on the other side of the vehicle, at
the opposite end.

Downloaded from www.Manualslib.com manuals search engine If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires sp~n at high speed, they can
explode, and you or others could be injured. And
the transmission or other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin
the wheels above 35 mph (55 km/h) as show]
on the speedometer.
1 NOTICE: I
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 transmission.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
