Towing a Trailer
Towing Equipment and
Accessories
Towing generally requires a variety
of supplemental equipment,
depending on the size of your trailer,
how much load you are towing, and
where you tow. To ensure the best
quality, we recommend that you
purchase Acura equipment
whenever possible.
Discuss your needs with your trailer
sales or rental agency, and follow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and maintained,
and that it meets federal, state,
province, and local regulations.

Hitches
Any hitch used on your vehicle must
be properly bolted to the underbody.
Safety Chains
Always use safety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and 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.
Trailer Brakes
Acura 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
vehicle's hydraulic system. No
matter how successful it may seem,
any attempt to attach trailer brakes
to your vehicle's hydraulic system
will lower braking effectiveness and
create a potential hazard.
See your trailer dealer or rental
agency for more information on
installing electric brakes.
