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 esp\
ecially important in trailer operation are automatic transmission fluid (don’t ove\
rfill),
engine oil, axle lubricant, belt, cooling system, and brake adj\
ustment. 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 Light Wiring
See “Trailer Wiring Harness” in the Index.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle is stationary or anchored.
NOTICE
Use the regular brakes, set the parking brake Or UIWK ihe wheels IW keep
your vehicle from rolling.

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 syst\
ems.
1 CAUTION
* You could be injured if the vehicles roll. Set the parking brake \
firmly I
on each vehicle. Put an automatic transmission in P (Park) or a
manual transmission in
N (Neutral).
If you have a four-wheel-drive vehicle with a manual transfer case\

shift lever, be sure the tra-fer case is not in
N (Neut--’).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
I
needed, and radios. This will avoid sparks and help save both \
batteries.
And it could save your radio!
4. Open the hoods and locate the batteries. Find the positive (t) arlu
negative
(-) terminals on each battery.
* Using a match near a battery can cause battery gas to explode. I
People have been hurt doing this, and some have been blinded. \
Use
a flashlight if you need more light.
You don’t need to add water to the Delco Freedom@ battery \
installer’
in every new
GM vehicle. But if a battery has filler caps, be sure thG
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
I with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged, too.

When your vehicle is being towed, have the ignition key off. The steering
wheel should be clamped in a straight-ahead position with a clamping device
designed for a towing service. Do not use the vehicle's steeri\
ng column
lock for this. The transmission (either automatic or manual) should\
be in
N (Neutral) and the transfer case (either manual shift or elec\
tronic shift), if
you have one, should be in 2 WHEEL (two-wheel drive). The parking brake
should be released.
Don't have your vehicle towed on the rear (drive) wheels, un\
less you have
to,
If the vehicle must be towed on the rear wheels, don't go more than 35 mph
(56 km/h) or farther than 50 miles (80 km) or your transmission will be
damaged.
If these limits must be exceeded, then the rear drive wheels have\

to be supported on a dolly.
If your vehicle has the four-wheel-drive option, a dolly
MUST be used under
the rear wheels when towing from the front.

8. Then replace the pressure cap. Be sure the arrows on the pres\
sure 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 every day
driving conditions the clutch is not engaged. This improves fue\
l economy and
reduces fan noise. Under heavy vehicle loading, trailer towing andlor high
outside temperatures, the fan speed increases when the clutch e\
ngages.
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 whe\
n 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 “blowout” while you’re d\
riving, 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 pu\
lls 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.

Downloaded from www.Manualslib.com manuals search engine Problems on the Road
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 accelerator pedal. Get the vehicle under co\
ntrol 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 your tire goes flat, the next part shows how to use your jac\
king 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.
I CAUTION I
A Changing a tire can cause an injury. The vehicle can slip off the jack
A and roll over you or other people. You and they coulld be badly
injured. Fin'd a level place to change your tire. To help prevent the
vehicle from moving:
I. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Shift a manual transmission to 1 (First) or R (Reverse).
4. If you have a four-wheel-drive vehicle with a manu'al transfer
case
shift lever, be sure the transfer case is in a drive
gear-not
in ' N (Neutral).
5- Turn off the engine.
To be even more certain the. vehick won't move, you can put 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.
