Downloaded from www.Manualslib.com manuals search engine Parking on Hills
You really should not park your vehicle, with a trailer attached, \
on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into P (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb
the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
shift to
P (Park).
5. Release the regular brakes.
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 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.

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
I
A You could be injured if the vehicles roll. Set the parking brake firmly
b on each vehicle. Put an automatic transmission in P (Park) or a
I manual transmission in N (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
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) and the
negative
(-) terminals on each battery.
1 CAUTION
A 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.
You don’t need
to add water to the Delco 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
I with water and get medical help immediately.
5. Check that the jumper cables don’t have loose or missing in\
sulation. If
they do, you could get a shock. The vehicles could be damaged\
, too.
Before you connect the cables, here are some things you should\
know.
Positive
(t) will go to positive (+) and negative (-) will go to negative
(-) or a metal engine part. Don’t connect (t) to (-) or you’ll get a
short that would damage the battery and maybe other parts,
too.

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.
They can provide the right equipment and know how to tow it without
damage.
If your vehicle has been changed or modified since it was factory-new by
adding aftermarket items like fog lamps, aero skirting, or special tires and
wheels, these things could be damaged during towing.
Before you do anything, turn on the hazard warning flashers.
When you call, tell the towing service:
That, if your vehicle has all-wheel drive or rear-wheel drive with fog
lamps, it cannot be towed from the front with sling-type equipment.
That your vehicle has rear-wheel drive, or that it has the all-wheel-drive
option.
The make, model, and year of your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
* To help avoid injury to you or others:
I
Never let passengers ride in a vehicle that is being towed.
Never tow faster than safe or posted speeds.
Never tow with damaged parts not fully secured.
Never get under your vehicle after it has been lifted by the tow
Always use separate safety chains on each side when towing a
truck.
I vehicle.
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 towing service. Do not use the vehicle’s steering column lock for
this. The transmission should be in
N (Neutral) and the parking brake
released.
If your vehicle has the all-wheel drive option, it can only be towed with
all four wheels
off the ground. A dolly must be used under the un-raised
wheels when towing or the vehicle must be transported
on a flat bed
carrier.

Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h 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 fu\
el 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 Tim 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, 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 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 jacking equipment
to change a flat tire safely.

Downloaded from www.Manualslib.com manuals search engine 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
4
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 the shift lever in P (Park).
3. Turn off the engine.
To be even more certain the vehicle won’t move, you can put chocks
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.

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.
Engine Oil
It’s a good idea to check your engine oil every time you get fuel. In order to
get an accurate reading, the oil must be warm and the vehicle\
must be on level ground.
