Towing a Trailer (cont'd)
Hitches
Use only a hitch recommended by your Honda dealer. The hitch
should be bolted securely to the car and installed by a qualified
technician. Do not use a hitch designed for temporary installation
and never use one that attaches only to the bumper.
Trailer Brakes and safety chains
The Honda Automobile Division recommends that trailers equipped
with brakes, should conform to any applicable federal and state
regulations, When using a trailer equipped with electric brakes, a
trailer brake controller that connects to the car's electrical system is
recommended. Installing a brake controller that connects to the car's
brake hydraulic system could result in brake fluid contamination or
leaks, A safety chain must always be used between the car and the
trailer. Leave sufficient slack in the chain so that it does not bind in
sharp turns. The chain should cross under the trailer tongue to
prevent the tongue from dropping to the ground.
Tires
Make sure your car's are properly inflated. Adjust tire pressure
to the recommended tire pressure indicated on the label attached to
the edge of the driver's door.The trailer tires should be of the
proper size, load rating and inflated to the pressure recommended
by the trailer manufacturer.
Trailer Lights
Trailer light must comply with federal, state and local regulations.
See your local recreation vehicle dealer or rental agency for the
correct type of lighting and wiring for your trailer, Check for correct
operation of the turn signals and stop lights each time you hitch up.
CAUTION:
Connections to your car's electrical system should be made by
your Honda dealer or a qualified electrician.Improper installation
may damage your vehicle's electrical system and cause a
malfunction of the lights.
