4-38 Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns
than normal. Do this so your trailer won't strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument panel
will flash whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also flash,
telling other drivers you're about to turn, change lanes
or stop.When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It's important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don't shift
down, you might have to use your brakes so much
that they would get hot and no longer work well.
On long uphill grades, reduce speed to 45 to 50 mph
(70 to 90 km/h) and avoid prolonged use of SECOND (2)
gear and engine speeds above 3800 rpm.
Climbing grades steeper than four percent at temperatures
above 90
F (32
C) with a loaded vehicle and trailer is
not recommended. The cooling system may temporarily
overheat. See ªEngine Overheatingº in the Index.

4-39 Parking on Hills
CAUTION:
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 do not shift
into PARK (P).
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 shift into
PARK (P) firmly and apply your parking brakes.
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

Be sure the parking brake has released.
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 booklet
for more on this. Things that are especially important in
trailer operation are automatic transaxle fluid (don't
overfill), engine oil, drive belt, cooling system and brake
system. If you're trailering, it's a good idea to review
this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

2. Get the vehicles close enough so the jumper cables
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 parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic transaxle
in PARK (P) or a manual transaxle in NEUTRAL
before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. 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 repairs wouldn't be covered by
your warranty.
Open the hoods and locate the battery on the other
vehicle and the remote positive (+) terminal located
on the passenger's side of the engine compartment
of your vehicle. (You will not see the battery under
the hood of your vehicle, since it is located under
the rear seat on the passenger's side.) Find the
positive (+) and negative (
-) terminals on the
battery in the other vehicle.
You do not need to access your battery for jump
starting. The remote positive (+) terminal, located
on the passenger's side of the engine compartment,
is for this purpose.

CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
4. Lift and move the
red positive (+)
terminal cover
away from the
relay center.
CAUTION:
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
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.

5. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a shock.
The vehicles could also be damaged.
Before you connect the cables, here are some basic
things you should know. Positive (+) will go to
positive (+) and negative (
-) will go to a heavy,
unpainted metal engine part. Don't connect
positive (+) to the negative (
-) or you will get a
short that would damage the battery and maybe other
parts, too. Also, don't connect the negative (
-) cable
to the negative (
-) terminal on the dead battery
because this can cause sparks.
CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
6. Connect the red
positive (+) cable to
the remote positive (+)
terminal of your vehicle.
7. Don't let the other
end of the positive (+)
cable touch metal.
Now, connect the red
positive (+) terminal
to the red positive (+)
terminal of the other
vehicle's battery. Use
a remote positive (+)
terminal if the vehicle
has one.

5-7
8. Now connect the
black negative (
-) cable
to the good battery's
negative (
-) terminal.
Don't let the other end of the negative (
-) cable touch
anything until the next step. The other end of the
negative (
-) cable doesn't go to the dead battery.
Your vehicle has a
remote negative (
-)
terminal, marked
ªGND (
-)º located
near the power
steering fluid reservoir.
Attach the cable to the
remote negative (
-)
terminal provided.
If the SECURITY light flashes, wait until the light
stops flashing before starting the engine.
9. Now start the vehicle with the good battery and run
the engine for a while.
10. Try to start the vehicle with the dead battery.
If it won't start after a few tries, it probably
needs service.

11. Remove the cables in reverse order (as shown in the
following procedure) to prevent electrical shorting.
Take care that they don't touch each other or any
other metal. Return the red positive (+) remote
terminal cover to its original position.
Jumper Cable Removal Procedure
A. Remote Positive (+) Terminal
B. Good Battery
C. Heavy, Unpainted Metal Engine Part1. Disconnect the black negative (
-) cable from the
remote negative terminal (GND) or the heavy,
unpainted metal engine part on the vehicle that
had the dead battery.
2. Disconnect the black negative (
-) cable from
the negative (
-) terminal on the vehicle with the
good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
