CHEVROLET 2010 Silverado - Manual (Page 407)

{ 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/retailer 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/retailer 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.
