9-88 Driving and Operating
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 the brakes cannot work
properly, you could have a crash.
To help the 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(Continued)
WARNING (Continued)
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 vehicle with full
fuel and passengers. It is the
amount of weight that can be added
to the vehicle before reaching
theGVWR. Keep in mind that
reserve capacity numbers are
intended as a guide when selecting
the amount of equipment or cargo
the vehicle can carry. If you are
unsure of the vehicle's front, rear,
or total weight, go to a weigh station
and weigh the vehicle. Your dealer
can also help you 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
Vehicle Load Limits on
page 9‑16.
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 6‑6 for switch location.
