Malfunction Indicator
(SERVICE ENGINE SOON) Lamp
The Malfunction Indicator (SERVICE ENGINE SOON) Lamp on your
instrument panel lets you know when your emission system needs service.
The light
will come on briefly when you start your engine to let you know
that the system is working.
If it does not come on when you start your
engine,
or if it comes on and stays on while you're driving, your system
may need service. Your vehicle should still be driveable, but
you should
have your system serviced right away.
Secondary Air Injection Reaction (AIR) System
You may have this system. It has a control valve that will direct air to where
it is needed. If the AIR system needs service, your Malfunction Indicator
(SERVICE ENGINE SOON) Lamp on your instrument panel will come
on.

on the

of your original tires and the inflation pressures
needed to obtain the gross weight capacity
of your vehicle. This is called the.
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight
of
the vehicle, all occupants, fuel and cargo.
The Certificatioflire label also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR).
To find out
the actual loads on your front and rear axles,
you need to go to a weigh
station and weigh your vehicle. Your dealer can help you with this.
Be sure
to spread out your load equally on both sides of the centerline.

Bulletins cover various subjects. Some pertain to the proper use and care of
your vehicle. Some describe costly repairs. Others describe inexpensive
repairs which, if done on time with the latest parts, may avoid future costly
repairs. Some bulletins tell
a technician how to repair a new or unexpected
condition. Others describe
a quicker way to fix your vehicle. They can help
a technician service your vehicle better.
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’s bulletins by calling Helm, Inc. at
1-800-7824356. This way
you’ll get them as they become available.
Individual PSP’s
If you don’t want to buy all the PSP’s issued by Chevrolet for all car or
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 PSP’s published by Chevrolet in a model year (1990 or later).
PSP’s covering all models
of Chevrolet cars or light trucks (less than
10,000 pounds
(4 536 kg) GVWR) are listed in the same index.
0 Ordering information so you can buy the specific PSP’s you may want.
0 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 car or 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 for earlier
model years.
Lut 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
1989-1994 model years.
