Following Distance
Stay at least twice as far behind the vehicle ahead as you w\
ould when
driving your vehicle without a trailer. This can help you avoi\
d situations that require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re to\
wing a trailer.
And, because you’re a good deal longer, you’ll need
to go much farther
beyond the passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer left, just move your hand to the left. To move the trailer to the right,
move your hand
to the right. Always back up slowly and, if possible, have
someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than n\
ormal. Do this so
your trailer wheels 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 has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument \
panel will flash
whenever you signal a turn or lane change. Properly hooked up,\
the trailer lights will also flash, telling other drivers you’re about
to turn, change lanes,
or stop.
When towing a trailer, the green arrows on your instrument pan\
el 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 work\
ing.
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 a long uphill grade, shift down and reduce your speed to \
around
45 mph
(70 km/h) to reduce the possibility of engine and transmission ove\
rheating.
If you have an automatic transmission, you should use D when towing a
trailer. Operating your vehicle in
D when towing a trailer will minimize heat
buildup and extend the life of your transmission. Or, if you have a manual
transmission with fifth gear, it’s better not to use fifth \
gear, just drive in fourth
gear (or, as you need
to, a lower gear).

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.

If the level is below the bottom of the filler plug hole, you’ll need to add
some lubricant.
If the differential is at operating temperature (warm), add enough lubricant to
raise the level
to the bottom of the filler plug hole.
If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12 mm) below the filler plug hole.
What to Use:
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants” in the Index.\

Engine Coolant
The following explains your cooling system and how to add coolant when it is
low.
If you have a problem with engine overheating, see “Engine
Overheating’’ in the Index.

Headlights
The headlight wiring is protected by a circuit breaker in the \
light switch. An electrical overload will cause the lights to go on and
off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker a\
nd a fuse. If
the motor overheats due to heavy snow, etc., the wiper will s\
top until the
motor cools. If the overload is caused by some electrical problem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows a\
nd other power
accessories. When the current load is
too heavy, the circuit breaker opens
and closes, protecting the circuit until the problem is fixed \
or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring I ;s is protected by an in-line fuse
in the battery feed wire. This fuse is near rhe junction bloc\
k. See “Trailer
Wiring Harness” in the “Features
& Controls’’ section.

Your Chevrolet dealer or a qualified technician may have to determine
if a
specific bulletin applies

Individual PSP’s
If you don’t want to buy all the PSP’s issued by Chevrolet for all car and
truck models in the model year, you can buy individual PSP’s, such as those\

which may pertain
to a particular model. To do this, you will first need to see
our index of PSP’s. It provides a variety of information. Here’s what you’ll find
in the index and how you can get one:
What You’ll Find in the Index:
A list of all PSP’s published by Chevrolet in a model year (1 989 or
later). PSP’s covering all models of Chevrolet cars or light trucks less
than
10,000 pounds (4536 kg) GVWR are listed in the same index.
Ordering information so you can buy the specific PSP’s you may want.
Price information for the PSP’s you may want to buy.
How You Can Get an Index:
Indexes are published periodically. Most of the PSP’s which could potentially
apply
to the most recent Chevrolet models will be listed in the most recent
publication for that model year. This means you may want to wait until the
end of the model year before ordering an index,
if you are interested in
buying PSP’s pertaining to a current model year truck.
Some PSP’s pertaining to a particular model’ year vehicle may be published in
later years, and these would be listed
in the later year’s index. When you
order an index for a model year that is not over yet, we’ll send you the most
recently published issue. Check the ordering form for indexes f\
or earlier model
years.
Cut out the ordering form,
fill it out, and mail it in. We Will. then see to it that
an index is mailed to you. There is no charge for indexes for the 1989-19\
93
model years.
Toll-Free Telephone Number
If you want an additional ordering form for an index or a subscr\
iption, just
call toll-free and we’ll be happy to send you one. Automated recording
equipment will take your name and mailing address. The number to call
