the airflow to the radiator. This could be
more noticeable as vehicle speed
increases. At speeds above 72 km/h
(45 mph), this may cause the engine
coolant to overheat. Move or angle the
snow plow blade to allow increased
airflow to the radiator.
To increase the airflow, move the snow
plow blade position.
If driving more than 24 km/h (15 mph),
angle the plow blade position.
Make sure the weight on the front and
rear axles does not exceed the axle rating
for each.
Follow the snowplow manufacturer’s
recommendations for any rear ballast that
may be required. Rear ballast may be
required to ensure a proper front and rear
weight distribution ratio even though the
actual weight at the front axle may be
less than the front axle rating.
The snowplow manufacturer or installer
can assist in determining the amount of
rear ballast required to ensure that the
vehicle with the attached snowplow does
not exceed the GVW rating, the front and
rear axle ratings, or the front and rear
weight distribution ratio (refer to the GM
Upfitter Manual).
Caution (Continued)
repairs would not be covered by the
vehicle warranty. Unless the vehicle was
built to carry a snow plow, do not add
one to the vehicle. If the vehicle has RPO
VYU, then the payload the vehicle can
carry will be reduced when a snow plow
is installed. The vehicle can be damaged
if either the front or rear axle ratings or
the Gross Vehicle Weight Rating (GVWR)
are exceeded.
The vehicle has an airbag system. Before
attempting to add anything electrical to the
vehicle, see Servicing the Airbag-Equipped
Vehicle 0 68 and Adding Equipment to the
Airbag-Equipped Vehicle 0 68.

Adding a Snow Plow or Similar
Equipment
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 to
be carried.
The weight of items added to the vehicle,
like a tool box or truck cap.

Caution
Do not exceed 72 km/h (45 mph) with a
snow plow mounted to the vehicle. The
vehicle could overheat and be damaged.
Before installing a snow plow on the vehicle,
follow these guidelines:

The total weight of any additional cargo
to be carried.
Caution
To safely carry a snow plow on the vehicle:
If the vehicle does not have the snow
plow prep package, RPO VYU, adding a
plow can damage the vehicle, and the
