Check the weight of the unhitched
trailer. Limit: See page .Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase
Honda equipment whenever possible.
Calculate the tongue load.
Subtract the weight in step 6 f rom
the weight in step 7.
Limit: See page .
Recommended: See page . Your dealer of f ers an optional trailer
package f or models other than RTX.
The package includes a hitch, a ball
mount, and a wiring harness.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state, f ederal, province,
and local regulations.
A weight distributing hitch is not
recommended f or use with your
vehicle, as an improperly adjusted
weight distributing hitch may reduce
handling, stability, and braking
perf ormance.
Read the trailer manufacturer’s
instructions, and select the
appropriate draw bar f or the height
of the trailer you will be towing.
We strongly recommend that you
have your dealer install a class 3

There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
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 successf ul it may seem,
any attempt to attach trailer brakes
to your vehicle’s hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.
Seeyourtrailermanufacturerfor
more inf ormation on installing
electric brakes.
Honda requires that any trailer with
a total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.A f actory installed, 4-pin gray
connector is located under the
instrument panel near the top of the
parking brake pedal. This connector
has all of the circuits required to
install most electric trailer brake
controllers. A jumper harness to
adapt your electric trailer brake
controller to the vehicle is included
with the optional Genuine Honda
trailer hitch kit. To obtain a trailer
hitch kit, see your dealer.
Have a qualif ied mechanic install
your trailer brake controller
f ollowing the trailer brake controller
manuf acturer’s instructions. Failure
to properly install the trailer brake
controller may increase the distance
it takes f or you to stop your vehicle
when towing a trailer.Use this illustration to identif y each
terminal in the trailer brake
controller connector.

Always use saf ety 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.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire for your vehicle
and trailer. See page f or proper
tire size, page f or how to store a
full size wheel and tire, and page
f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire. 271

light requirements f or the areas
where you plan to tow, and use only
equipment designed f or your vehicle.We recommend that you have your

been designed f or your vehicle.
Ref er to the above illustration f or
wiring information.
Your vehicle is equipped with a
connector to install an optional trailer
lighting connector that mates with
your vehicle. Since lighting and wiring vary with
trailer type and brand, you should
also have a qualif ied mechanic install
a suitable connector between the
vehicle and the trailer.
