Towing Equipment

Hitches
The correct hitch equipment helps
maintain combination control. Many
trailers can be towed with a weight
carrying hitch which simply features
a coupler latched to the hitch ball,
or a tow eye latched to a pintle
hook. Other trailers may require a
weight distributing hitch that uses
spring bars to distribute the trailer
tongue weight among the two
vehicle and trailer axles. See
Weight of the Trailer Tongue in
Trailer Towing on page 9 59 for
rating limits with various hitch types.
Consider using sway controls with
any trailer. Ask a trailering
professional about sway controls or
refer to the trailer manufacturer's
recommendations and instructions.
Weight Distributing Hitch
Adjustment
A. Body to Ground Distance
B. Front of Vehicle
When using a weight-distributing
hitch, the spring bars should be
adjusted so the distance (A) is the
same after coupling the trailer to the
tow vehicle and adjusting the hitch.
Driving and Operating
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. If the trailer being
towed weighs up to 2 271 kg
(5,000 lbs) with a factory-installed
step bumper, safety chains may be
attached to the attaching points on
the bumper, otherwise, safety
chains should be attached to holes
on the trailer hitch platform. Always
leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
