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.

Automatic Transmission Nuid
When to Check and Change:
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule
to determine when
to change your fluid. See “Scheduled Maintenance Services” in the Index.
How to Check:
Because this operation can be a little difficult, you may choo\
se to have this
done at a
GM dealership 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.
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 part-
starting a fire. Be sure to get an accurate reading
if you check your
transmission fluid.
I
I
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.

1. Pull out the dipstick and wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait 3 seconds and 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 where it should be, push the dipstick back in all the
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.
If the fluid level is low, add only enough to bring the level up to the COLD
area
for a cold check or 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 DEXRON@IIE, because fluids with that label are ma\
de especially
for your automatic transmission. Damage caused by other fluid t\
han DEXRON*IIE
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check”.
When the correct fiuid level is obtained, push the dipstick back in all the
way.
