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 hjection 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.

The Certification/Tire
label is found on the
rear edge of the
driver’s door or
in the
Incomplete Vehicle
Document
in the cab.
The label shows
the size 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 Certification/Tire 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.
Never exceed the GVWR for your vehicle, or
the GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.

A CAUTION:
In the case of a sudden stop or collision, things carried in the bed
of your truck could shift forward and come into the passenger
area, injuring you and others.
If you put things in the bed of
your truck, you should make sure they are properly secured.
A CAUTION:
Do not load your vehicle any heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts on your
vehicle-can break, or it can change the way your vehicle handles.
These could cause you to lose control. Also, overloading can
shorten the Iife
of your vehicle.
Using heavier suspension components to get added durability might not
change your weight ratings.
Ask your dealer to help you load your vehicle
the right
way.
NOTICE:
Your warranty does not cover parts or components that fail
because
of overloading.
If you put things inside your vehicle-like suitcases, tools, packages, or
anything else-they
go as fast as the vehicle goes. If you have to stop or
turn quickly, or if there is a crash, they’ll keep going.

Trailering Package
If your vehicle comes with the Trailering Package, there is also a load rating
which includes the weight
of the vehicle and the trailer it tows. This rating
is called the Gross Combination Weight Rating (GCWR).
When you weigh your trailer, be sure
to include the weight of everything
you put
in it. And, remember to figure the weight of the people inside as
part of your load.
Your dealer can help you determine your GCWR.

Add-on Equipment
When you carry removable items, like snow plow blades, you may need to
put
a limit on how many people you carry inside your vehicle. Be sure to
weigh your vehicle before you buy and install the new equipment.

Truck-Camper Loading Information
Open your glove box door and look for this label:
This label will
tell you how much of a load your vehicle can carry, and how
to spread out your load the right way.
Also, it will help you match the right
slide-in camper to your vehicle.
When you carry a slide-in camper,
the total cargo load of your vehicle is the
weight
of the camper, plus
everything else added to the camper after it left the factory;
0 everything in the camper: and
0 all the people inside.
The Cargo Weight Rating (CWR)
is the maximum weight of the load your
vehicle can carry. It doesn’t include the weight
of the people inside. But,
you can figure about
150 pounds for each seat.
The total cargo
load must not be more than your vehicle‘s CWR.

The camper’s center
of gravity should fall within the center of gravity zone
for your vehicle’s cargo load.
You must weigh any accessories or other equipment that you add to your
vehicle.
Then, subtract this extra weight from the CWR. This extra weight
may shorten the center of gravity zone
of your vehicle. Your dealer can help
you with this.
If your slide-in camper and
its load weigh less than the CWR, the center of
gravity zone for your vehicle may be larger.
Your dealer can help you make
a good vehicle-camper match. He’ll also
help you determine your CWR.

After you’ve loaded your vehicle and camper, drive to a weigh station and
weigh
on the front and rear wheels separately. This will tell you the loads on
your axles. The loads
on the front and rear axles shouldn’t be more than
either of the GAWRs. The total
of the axle loads should not be more than
the GVWR.
Open your driver’s door and look at
the CertificatiodTire label to find out
your CWAR and GVWR.
If
you’ve gone over your weight ratings, move or take out some things until
all the weights fall below the ratings. Of course, you should always tie down
any loose items when you load your vehicle or camper.
When you install and load your slide-in camper, check the manufacturer’s
instructions.
If
you want more information on curb weights, cargo weights, cargo weight
rating and the correct center of gravity zone for your vehicle, your dealer
can help
you. Just ask for a copy of “Consumer Information, Truck-Camper
Loading.”
Trailer Recommendations
You must subtract your hitch loads from the CWR for your vehicle. Weigh
your vehicle with
the trailer hitch attached, so that you won’t go over the
GVWR or the GAWR.
You’ll get the best performance if you spread out the weight of your load
the right way, and if‘ you choose the correct hitch and trailer brakes.
For more information, see “Trailer Towing’’
in the Index.
Pickup Conversion To Chassis Cab
General Motors is aware that some vehicle owners may consider having the
pickup box removed and
a commercial or recreational body installed.
Before
you do so, first contact the GM Zone Office for your area for
information on such conversions. (See the “Warranty and Owner
Assistance” booklet for Zone Office.) Owners should be aware that, as
manufactured, there are differences between a chassis cab and a pickup with
the box removed which may affect vehicle safety. The components
necessary to adapt
the pickup to permit its safe use with a specialized body
should be installed by a body builder
in accordance with the information
available from
the Zone Office.

Tf you are skilled enough to do some work on your vehicle, you will
probably want to get the service information
GM publishes. For information
on how
to obtain various service publications for your vehicle, see “Service
Publications”
in the Index. You will find a list of publications and an order
form
in the back of the book.
Scheduled Maintenance Services
This part tells you the maintenance services that you should have done and
the times you should schedule them. Your
GM dealer knows your vehicle
best and wants you to be happy with
it. If you go to your dealer for your
service needs, you’ll know that GM-trained and supported service people
will perform the work using genuine
GM parts.
These schedules are for vehicles that:
0 carry passengers and cargo within the recommended limits. You will
find these limits on your vehicle’s Certification Label. See “Loading
Your Vehicle’’ in the Index.
are driven on regular road surfaces, and within legal driving limits, as
described in Section 4 “Your Driving and the Road.”
0 are driven off-road in the recommended manner. See “Off Road
Driving With Your Four-wheel Drive Vehicle”
in the Index.
0 use the recommended fuel. See “Fuel” in the Index.
Selecting the Proper Maintenance Services
To find the proper maintenance schedule for your vehicle, you must know
two things. What engine your vehicle has, and how you
use your vehicle.
Your engine type will tell
you which chart to use, and your driving
conditions will tell
you which schedule to use. ’The charts are found later in
this section.
Selecting the Proper Maintenance Chart
Your engine type (Gasoline or Diesel) and its emissions classification (Light
Duty or Heavy Duty Emissions) will
tell you which maintenance chart to
use. Find your Vehicle Identification Number (VIN), and look at the eighth
character
to see what your engine code is. Then use the following Engine
Emissions Classifications tables
to find your emissions classification.
Your VIN is on the plate on the top left corner of your instrument
panel, the Certification Label and on the Service Parts Identification
Label. See “Vehicle Identification Number’’
in the Tndex.
If your engine has more than one emissions classification, look at your
Certification Label to see what your Gross Vehicle Weight Rating
(GVWR)
is. See “Loading Your Vehicle” in the Index.
