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, trailer hitches or other equipment you add
to your vehicle. Then, subtract this extra weight from the CWR,
This extra
weight may shotten the center of gravity zone for 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 th\
an
either
of the GAWRs. The total of the axie..loads should not be more than
the GVWR.
Open your driver’s door and look at the door lock pillar f\
or the CertificationKire label to find out your GWAR and GWVR.
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.

Pickup Conversion fo Chassis Cab
General Motors is aware that some vehicle owners may consider having the
pickup box removed and a commercial or recreational body installed. Be\
fore
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, th\
ere are
differences between a chassis cab and a pickup with the box r\
emoved which
may affect vehicle safety. The components necessary to adapt the pickup to
permit its safe use with a specialized body should be installe\
d by a body
builder in accordance with the information available from the Zone Office.
Tires
We don’t make tires. Your new vehicle comes with high quality tires made by
a leading tire manufacturer. These tires are warranted by the tire
manufacturers and their warranties are delivered with every new vehicle. If
your spare tire is a different brand than your road tires, you will have a tire
warranty folder from each of these manufacturers.
4 Poorly maintained and improperly used tires are dangerous.
Overloading your tires can cause overheating as a result of too
much friction. You could have an air-out and a serious accide
See “Loading Your Vehicle” in the Index.
Underinflated tires pose the same danger as overloaded tires.
The resulting accident could cause serious injury. Check all tires
frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold.
I
Overinflated tires are more likely to be cut, punctured, or broken
by sudden impact such as when you hit a pothole. Keep tires ar

Inflation-Tire Pressure
The Certification/Tire label, which is on the driver’s door \
lock pillar, shows the
correct inflation pressures for your tires, when they’re cold\
. “Cold’’ means your
vehicle has been sitting for at least three hours or driven n\
o more than a mile.
I NOTICE I
When to Check: Check your tires once a month or more. Don’t forget \
your
compact spare tire (if
so equipped). It should be at 60 psi (420 kPa).
How to Check: Use a good quality pocket-type gage to check tire pressure.
Simply looking at the tires will not tell you the pressure, e\
specially
if you
have radial tires-which may
l’ook properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure
to put them back on. They help
prevent leaks by keeping out dirt and moisture.
Ere lnspection and Rotation
To make your tires last longer, have them inspected and rotated a\
t the
mileages recommended in the Maintenance Schedule. See Scheduled
Maintenance Services in the Index.

When It’s Time for New Tires
K1656
One way to tell when it’s time for new tires is to check the treadwear
indicators, which will appear when your tires have only
2/32 inch (1.6 mm) or
less of tread remaining.
You need a new tire
if:
You can see the indicators at three places around the tire.
You can see cord or fabric showing through the tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep enough to show
cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t b\
e repaired
because of the size
or location of the damage.
Buying New Eres
To find out what kind and size of tires you need, look at the CertificationRire
label. The tires installed on your vehicle when it was mew had a Tire
Performance Criteria Specification (TPC Spec) number on each t\
ire’s sidewall.
When you get new tires, get ones with that same TPC Spec num\
ber. That
way, your vehicle will continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other thin\
gs during
normal service on your vehicle.
If your tires have an all-season tread design,
the TPC number
will be followed by a “MS” (for mud and snow).

Cleaning the Outside of Your Windshield and Wiper Blades
If the windshield is not clear after using the windshield washer, or if the wiper
blade chatters when running, wax or other material may be on the blade or
windshield.
Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@ (GM Part
No. 1050011). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced\
when worn.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand or dish or car washing\
(non-detergent) soaps. Don’t use cleaning agents that contai\
n acid or
abrasives. All cleaning agents should be flushed promptly and n\
ot allowed
to
dry on the surface, or they could stain. Dry the finish with \
a soft, clean
chamois or
100% cotton towel to avoid surface scratches and water spotting.
High pressure car washes may cause water
to enter your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get GM approved \
cleaning
products from your dealer. (See “Appearance Care and Materia\
ls’’ in the Index.)
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep their luster. Washing
with water is all that is usually needed. However, you may us\
e GM Chrome
Polish on chrome or stainless steel trim,
if necessary.
Use special care with aluminum trim.
To avoid damaging protective trim, never
use auto or chrome polish, steam or caustic soap to clean aluminum.
A
coating of wax, rubbed to a high polish, is recommended for all bright metal
parts.

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.

A Word About Maintenance
We at General Motors want to help you keep your vehicle in good working
condition. But we don’t know exactly how you’ll drive it. You may drive ve\
ry
short distances only a few times a week. Or you may drive lo\
ng distances all
the time in very hot, dusty weather. You may use your vehicle in making
deliveries. Or you may drive
it to work, to do errands, or in many other ways.
Because of all the different ways people use their GM vehicles, maintenance
needs vary. You may even need more frequent checks and replacements than
you will find in the schedules in this section.
So please read this section and
note how you drive. If you have any questions on how
to keep your vehicle
in good condition, see your
GM dealer, the place many GM owners choose
to have their maintenance work done. Your dealer can be relied upon to use
proper parts and practices.
Your Vehicle And The Environment
Proper vehicle maintenance not only helps keep your vehicle in good working
condition, but it also helps the environment.
All recommended maintenance
procedures are important. Improper vehicle maintenance or the re\
moval of
important components can significantly affect the quality of the air we breathe.
Improper fluid levels or even the wrong tire inflation can inc\
rease the level of
emissions from your vehicle. To help protect our environment, and to help
keep your vehicle in good condition, please maintain your vehicle properly.
A
Performing maintenance work on a vehicle can be dangerous. In
trying to
do some jobs, you can be seriously injured. Do your own
maintenance work only
if you have the required know-how and the
proper tools and equipment for the job.
If you have any doubt, have
a qualified technician
do the work.
b
If you are skilled enough to do some work on your vehicle, you will probably
want to get the service information
GM publishes. You will find a list of
publications and how to get them in Section
8, ‘Customer Assistance
Information”. See “Service Publications” in the Index.
The Maintenance Record provides a place for you to record the maintenance
performed on your vehicle. Whenever any maintenance is performed\
, be sure
to write
it down in this section. This will help you determine when your next
maintenance should be done. In addition, it is a good idea to keep your
maintenance receipts. They may be needed to qualify your vehicle for
warranty repairs.
