Hitches
Do not use hitches that clamp onto
the vehicle bumper. Use a load
carrying hitch. You must distribute
the load in your trailer so that 10 %
of the total weight of the trailer is
on the tongue.
Safety chains
Always connect the trailer's safety
chains to the frame or hook
retainers of the vehicle hitch. To
connect the trailer's safety chains ,
cross the chains under the trailer
tongue and allow slack for turning
corners.
If you use a rental trailer, follow the
instructions that the rental agency
gives to you.
Do not attach safety chains to
the bumper.
Trailer brakes
Electric brakes and manual
automatic or surgeĆtype trailer
brakes are safe if installed properly
and adjusted to the manufacturer's
specifications. The trailer brakes
must meet local and Federal
regulations.
Do not connect a trailer's
hydraulic brake system
directly to your vehicle's brake
system.Your vehicle may not have
enough braking power and your
chances of having a collision
greatly increase.
