Chevrolet 2010 Silverado, Owner'S Manual

You can add heavier equipment on the front of the
vehicle if you compensate for it by carrying fewer
passengers, less cargo, or by positioning cargo toward
the rear. This has the effect of reducing the load on the
front. However, the front GAWR, rear GAWR, and the
Gross Vehicle Weight Rating (GVWR) must never be
exceeded.
{
WARNING:
On some vehicles that have certain front mounted
equipment, such as a snow plow, it may be
possible to load the front axle to the front gross
axle weight rating (GAWR) but not have enough
weight on the rear axle to have proper braking
performance. If your brakes can not work properly,
you could have a crash. To help your brakes work
properly when a snow plow is installed, always
follow the snow plow manufacturer or installer's
recommendation for rear ballast to ensure a
proper front and rear weight distribution ratio,
even though the actual front weight may be less
than the front GAWR, and the total vehicle weight
is less than the gross vehicle weight rating
(GVWR). Maintaining a proper front and rear
weight distribution ratio is necessary to provide
proper braking performance.
Total vehicle reserve capacity is the difference between
the GVWR and the weight of the truck with full fuel and
passengers. It is the amount of weight that can be
added to the vehicle before reaching the GVWR. Keep
in mind that reserve capacity numbers are intended as
a guide when selecting the amount of equipment or
cargo the truck can carry. If unsure of the vehicle's front,
rear, or total weight, go to a weigh station and weigh the
vehicle. Your dealer can also help with this.
The total vehicle reserve capacity for the vehicle can be
found in the lower right corner of the Certification/Tire
label as shown previously.
See your dealer for additional advice and information
about using a snow plow on the vehicle. Also, see
Loading the Vehicle on page 5 ‑ 29 .
Emergency Roof Lamp Provisions
Vehicles with the RPO VYU snow plow prep package
also have an emergency roof lamp provision package,
RPO TRW. Wiring for the emergency roof lamp is
provided above the overhead console. See
Auxiliary
Roof-Mounted Lamp on page 4 ‑ 14 for switch location.
