■Weight distribution hitches
Your vehicle is designed to tow without the need for a load distributing hitch. If you
wish to use one, please c onsult your trailer maker for proper installation and set-up.
Improper set-up could degrade the handling, stability, and braking performance of
your vehicle.
■Safety chains
Always use safety chains when you tow a trailer. Leave enough slack to allow the
trailer to turn corners easily, but do not allow the chains to drag on the ground.
■Trailer brakes
Recommended for any trailer with a total weight of 1,000 lbs (450 kg) or more:
There are two common types of trailer bra kes: surge and electric. Surge brakes are
common for boat trailers, since the brakes will get wet.
If you choose electric brakes, be sure th ey are electronically actuated. Do not
attempt to attach trailer brakes to your ve hicle’s hydraulic system, as it will lower
braking effectiveness and create a potential hazard.
The 4-pin gray connector instal led in your vehicle has all of the circuits required to
install most electric trailer brake controllers.1 Trailer brakes
The 4-pin gray connector is located under the
instrument panel near the top of the parking brake
pedal.

Have a qualified mechanic install your trailer
brake controller followi ng the trailer brake
controller manufacturer’ s instructions. Failure
to properly install the trailer brake controller
may increase the distance it takes for you to
stop your vehicle when towing a trailer.
The trailer hitch harness is used to install the
controller for the electric trailer brakes.

■Trailer light
Trailer lights and equipment must comply with federal, state, province/territory, and
local regulations. Check with your local trailer sales or rental agency for the
requirements in the area where you plan to tow.
We recommend that you have a dealer install a Honda wiring harness and converter.
They are designed for your vehicle.1 Trailer light
The trailer lighting connect or is located behind the
trailer hitch.
Even if you are planning to use the non-Honda trailer
lighting harness and converte r, ask a dealer for the
correct connector and pins.

The 7-pin trailer connector is needed for your trailer lights. When inserting the
connector to the socket, ch eck if the connector and the socket are free of dirt,
moisture, or other foreign material.
The lighting and wiring of trailers can vary by type and brand. If a connector is
required, it should only be installed by a qualified technician.
■Sway control
This device can be used if your trailer te nds to sway. Your trailer maker can tell you
what kind of sway control you need and how to install it. Improper installation could
degrade the handling and stability of your vehicle.
■Trailer mirrors
Many states, provinces and te rritories require special exterior mirrors when towing a
trailer. Install special mirrors whenever you cannot clearly see behind you, or if the
trailer creates a blind spot.

uuTowing a Trailer uTrailer Stability Assist
Driving
Trailer Stability Assist
Helps to stabilize the vehicle and tra iler when the trailer severely sways.
■How trailer stability assist works
When the vehicle and trailer become unstable while driving, trailer stability assist
determines the cause. If the trailer oscilla tion is detected as the cause, and the
swaying increases, the system applies the br akes or controls engine output to reduce
vehicle speed.
Both the vehicle and trailer brake lights co me on automatically if you brake to
reduce vehicle speed.
1 Trailer Stability Assist
Trailer stability assist is not a function that prevents
the vehicle and trailer from swaying. Avoid high
speeds, abrupt steering, improper trailer load, and
sudden braking to keep the trailer from swaying.
When swayed too severely, the system becomes
ineffective, and you may lose control of your vehicle,
causing the trailer to roll over or get damaged. 2 Driving Safely with a Trailer P. 428
Trailer towing sway is caused by:
•Crosswinds
•Improper towbar down load
•Excessive Speed
The VSA ® system indicator blinks during the trailer
stability assist operation. 2 VSA ® Operation P. 476

Driving Safely with a Trailer
• Have the trailer properly serviced and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 418
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tr ailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the traile r tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
■Things You Need To Know Before Towing a Trailer
■Towing Speeds and Gears
■Turning and Braking
1Driving Safely with a Trailer
Operating speed when towing a trailer must not
exceed 62 mph (100 km/h).
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.
When towing a trailer, we recommend that you carry
a full-size spare wheel and tire for both your vehicle
and trailer. If you use the compact spare tire that
came with your vehicle, it could adversely affect
vehicle handling.
Remember to unhitch the tra iler before changing a
flat tire. Ask the trailer sales or rental agency where
and how to store the trailer’s spare tire.
1 Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h).
At higher speeds, the trai ler may sway or affect
vehicle handling.

Driving
• Monitor your temperature gauge. If it nears the mark, turn off the heating
and cooling system*/climate control system* and reduce speed. Pull to the side of
the road safely to cool down the engine if necessary.
• Shift to the position if the transmission shifts frequently.
If the vehicle tires slip when retrieving a boat from the water, keep the transmission
in
(D. This prevents damage to the transmission.
Towing Your Vehicle
Your vehicle is not designed to be towed behind a motorhome. If your vehicle needs
to be towed in an emergency, refer to the emergency towing information.

Off-Highway Driving Guidelines
General Information
Your vehicle has been designed primarily for use on pavement, however, its higher
ground clearance allows you to occasionally travel on unpaved roads. It is not
designed for trail-blazing, or othe r challenging off-road activities.
If you decide to drive on unpaved roads, you will find that it requires somewhat
different driving skills and that your vehicle will handle somewhat differently than it
does on pavement. Pay attention to the precautions and tips in this section, and get
acquainted with your vehicle before leaving the pavement.
Important Safety Precautions
To avoid loss of control or rollover, be sure to follow all precautions and
recommendations:
• Be sure to store cargo properly and do not exceed your cargo load limits.
2 Maximum Load Limit P. 413
•Whenever you drive, make sure you and your passengers always wear seat belts.
• Keep your speed low, and never go faster than the conditions allow.
• It’s up to you to continually assess the situation and drive within the limits.
1Off-Highway Driving Guidelines
Failure to operate your vehi cle correctly might result
in a crash or a rollover. 2 Important Handling Information P. 32
2 Precautions While Driving P. 438
Spinning the tires excessiv ely can also damage the
Intelligent VTM4 (i-VTM4) system.
3WARNING
Improperly operating this vehicle on or off-
pavement can cause a crash or rollover in
which you and your passengers could be
seriously injured or killed.
• Follow all instructions and guidelines in
this owner’s manual.
• Keep your speed low, and don’t drive
faster than conditions permit.
