Towing a Trailer
Safety Chains
Always use safety chains. Make sure
they are secured to both the trailer
and hitch, and that they cross under
the tongue so they can catch the
trailer if it becomes unhitched.
Leave enough slack to allow the
trailer to turn corners easily, but do
not let the chains drag on the ground.

Driving
Trailer Brakes
Honda recommends that any trailer
having a total weight of 1,000 lbs
(450 kg) or more be equipped with
its own electric or surge-type brakes.
If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your car's
hydraulic system. No matter how
successful it may seem, any attempt
to attach trailer brakes to your car's
hydraulic system will lower braking
effectiveness and create a potential
hazard.
See your trailer dealer for more
information on installing electric
brakes.
Trailer Lights
Trailer lights and equipment must
comply with federal, state, and
local regulations. Check with your
local recreational vehicle dealer
for the requirements in your area,
and use only equipment designed
for your vehicle.
Since lighting and wiring vary by
trailer type and brand, you should
have a qualified technician install
a suitable connector between the
vehicle and the trailer. Improper
equipment or installation can
cause damage to your vehicle's
electrical system and affect your
vehicle warranty.
