Service & Appearance Care
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.
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."
Pickup Conversion
lo.
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.
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.
