Towing Equipment

Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by and rough roads are
a few reasons why the right hitch is
needed.

The rear bumper on the vehicle is
not intended for hitches. Do not
attach rental hitches or other
bumper-type hitches to it. Use only
a frame-mounted hitch that does not
attach to the bumper.
Will any holes be made in the body
of the vehicle when the trailer hitch
is installed? If there are, then be
sure to seal the holes when the
hitch is removed. If the holes are not
sealed, dirt, water, and deadly
carbon monoxide (CO) from the
exhaust may get into the vehicle.
See Engine Exhaust on page 9 40.
Weight-Distributing Hitches and
Weight Carrying Hitches
(A) Body-to-Ground Distance (B)
Front of Vehicle
When using a weight-distributing
hitch, the hitch must be adjusted so
that the distance (A) remains the
same both before and after coupling
the trailer to the tow vehicle.
