The iyload Capacity is shown on the Certificatioflire label. This is the
maximum load capacity that your vehicle can carry. Be sure to \
include the
weight of the people inside as part of your load.
If you added any
accessories or equipment after your vehicle left the factory, remember to
subtract the weight of these things from the payload. Your dealer can help
you with this.
Trailering Package
If your vehicle comes with the Trailenng Package, mere 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, you may need to put a limit \
on how many
people you carry inside your vehicle. Be sure to weigh your v\
ehicle before you buy and install the new equipment.
NOTICE:
Your warranty doesn’t cover parrs or components that fail
because of overloading.

Open your glove box and look for this label:
This label will tell you
if your vehicle can carry a slide-in camper, 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;
everything in the camper; and
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,
vou can figure about
150 pounds for each seat.
I ne total cargo load must not be more than your vehicle’s CWR.

1. Recommended location for cargo center of gravity for cargo weight
Refer to Truck Camper Loading Information label in the glove box for
rating.
“A”and
“B” dimensions.
Use rear edge of load floor for measurement purposes
Example of Proper Truck and Camper Match
1. Camper center of gravity
2. Recommended center of gravity location zone
The camper’.s center of gravity should fall within the center of gravity zone
for your vehicle’s cargo load.
Page 268 of 340

Downloaded from www.Manualslib.com manuals search engine You must weigh any accessories, trailer hitches or other equipment you a\
dd
to your vehicle. Then, subtract this extra weight from the CWR\
. This extra weight may shorten 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 wei\
gh 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 door lock pillar for the
CertificationD‘ire label to find out your GAWR and GVWR.
11 you ve gone over ; Jr 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 manu\
facturer’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 your trailer 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.
However, we recommend that conversions of this type not be done to this
pickup. 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.
For further information, contact the GM Zone Office for your
area. (See the “Warranty and Owner Assistance” booklet fo\
r Zone Office.)

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.

The CertificatiodTire label which is on the driver’s door lock pillar, shows
the correct inflation pressures for your tires, when they’re cold. ‘‘C01d’~
means your vehicle has been sitting for at least three hours or driven no
more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not. If your tires don’t have enough air
(underinflation) you can get:
0 Too much flexing
0 Too much heat
0 Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
0 Bad handling
Rough ride
0 Needless damage from road hazards.

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your ..’ :s once a month or more. Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality pocket-type gage to check tire pressure. Si\
mply looking at the tires will
not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure to put them back on. The\
y help prevent
leaks by keeping out
dirt and moisture.
Special Tire Inflation
If you have 31xlOSOR15LT/C tires on your vehicle, and:
- You’ll be driving for very long at speeds of 66 mph (105 km/h) to
75 mph (120 km/h) where legal, inflate tires to 10 psi (70 Wa) more
than the recornended cold inflation pressures.
- You’ll be driving for very long at speeds of 76 mph (120 km/h) to
85 mph (1 35 km/h) where legal, cold inflation pressures should be
increased by
10 psi (70 Wa) and you must also reduce axle load
capacity by
10%. Do not drive over 85 mph (135 km/h) even when
it’s legal.
Inflation pressures should never exceed 10 psi (70 Pa) above the
inflation specified for
the maximum load of the tire.

To make your tires last longer, have them inspected and rotated at the
mileages recommended in the Maintenance Schedule. See “Schedul\
ed
Maintenance Services” in the Index.
Use this rotation
pattern.
The four wheel rotation is for aluminum wheels only. The five wheel
rotation is for steel wheels only.
If your vehicle has front tires with different load ratings or tr\
ead designs
(such as all season vs. ordoff road) than the rear tires, d\
on’t rotate your tires
front to rear.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the CertificatiodTire label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
