9-48 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. Follow the
manufacturer's recommendation
for attaching safety chains and
do not attach them to the bumper.
Always leave just enough slack so
the rig can turn. Never allow safety
chains to drag on the ground.
Trailer Brakes
Because the vehicle has antilock
brakes, do not try to tap into the
vehicle's hydraulic brake system.
If you do, both brake systems will
not work well, or at all.
Does your trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so you will be able to install, adjust
and maintain them properly.
