Notice: Do not add anything
electrical to the vehicle unless
you check with your dealer first.
Some electrical equipment can
damage the vehicle and the
damage would not be covered
by the vehicle's warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing the Airbag-Equipped
Vehicle on page 3‑46 and Adding
Equipment to the Airbag-Equipped

Adding a Snow Plow or
Similar Equipment
Before installing a snow plow on the
vehicle, here are some things you
need to know:
Notice: If your vehicle does
not have the snow plow prep
package, adding a plow can
damage your vehicle, and the
repairs would not be covered by
warranty. Unless your vehicle was
built to carry a snow plow, do not
add one to your vehicle. If your
vehicle has the snow plow prep
package, called RPO VYU, then
the payload your vehicle can
carry will be reduced when a
snow plow is installed. Your
vehicle can be damaged if either
the front or rear axle ratings or
the Gross Vehicle Weight (GVW)
are exceeded.
Some vehicles are built with a
special snow plow prep package,
called RPO VYU. If your vehicle
has this option, you can add a
plow to it, provided certain weights,
such as the weights on the vehicle's
axles and the Gross Vehicle
Weight (GVW), are not exceeded.
The plow the vehicle can carry
depends on many things, such as:
. The options the vehicle came
with, and the weight of those
options.
. The weight and number of
passengers you intend to carry.
. The weight of items added to
the vehicle, like a tool box or
truck cap.
. The total weight of any
additional cargo you intend
to carry.
