Adding A Snow Plow Or Similar Equipment - GMC TopKick 2007 Owner's Manual

Adding a Snow Plow or Similar
Equipment
If you will be installing a snow plow on your
vehicle, we recommend that the vehicle have the
snow plow prep package (RPO ANQ). Before
installing a snow plow, see your dealer for
information on other recommended optional
equipment and vehicle weight restrictions.
Notice: 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 GVW,
are exceeded. See your dealer for more
information.

CAUTION:
{
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.
