I NOTICE
’
I advice in this section.
Wing a trailer improperly can damage your vehicle and result in costly
epairs not covered by your warranty. To pull a trailer correctly, follow the
Every vehicle is ready for some trailer towing,
If it was built with trailering
options, as many are, it’s ready for heavier trailers. But \
trailering is different
than just driving your vehicle by itself. Trailering means changes in handling,
durability, and fuel economy. Successful, safe trailering takes \
correct equipment, and it has to be used properly.
That’s the reason for this section. In
it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that of your passengers,
So please read this section carefully before you
pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points.
e
e
There are many different laws having to do with trailering. Make sure
your rig
will be legal, not only where you live but also where you’ll be\

driving.
A good source for this information can be state or provincial
police.
Consider using sway control with a utility model
if your trailer will weigh
3,000 pounds (1361 kg) or less, or with a wagon model if your trailer
will weigh
4,000 pounds (1800 kg) or less. You should always use sway
control with a utility model
if your trailer will weigh more than 3,000
pounds (1 361 kg), or with a wagon model if your trailer will weigh more
than
4,000 pounds (1800 kg). You can ask a hitch dealer about sway
controls.
Don’t tow a trailer at all during the first
500 miles (800 km) your new
vehicle is driven. Your engine, axle, or other parts could be damaged.
Then, during the first
500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 kmlh) and don’t make starts at full throttle. That
will help your engine and other parts
of your vehicle wear in at the
heavier loads.

Most bulletins apply to conditions affecting a small number of cars or trucks.
Your Chevrolet dealer or a qualified technician may have to determine
if a
specific bulletin applies to your vehicle.
You can subscribe to all Chevrolet bulletins by calling Helm, Inc. at
1-800-782-4356. This way you’ll get them as they come out.
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’// Find in the Index:
A list of all PSP’s published by Chevrolet in a model year (1989 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 fo\
r the 1989-1993 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 is
1-800-551 -41 23.
