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.
