•If you cannot weigh the rear axle, subtract 1 from 2.
• The maximum gross combined weight (4) decreases by 2% for every 1,000 feet
(305 meters) of elevation.
• To calculate the tongue load, subtract 5 from 6.
• Refer to the trailer owner’s manu al for additional information.
1How to weigh the trailer loads using the public scale
Fully load the vehicle and trailer. An attendant who
watches the scale is needed as all occupants should
stay in the vehicle.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by the manufacturer), and then
measure the tongue load with an appropriate scale or
tongue gauge or estima te it based on cargo
distribution. Weight limit for 2WD models AWD models

Towing generally requires a vari ety of supplemental equipment.
To ensure the best quality, we recommend that you purchase Honda equipment
whenever possible.
Your vehicle has a class 3 trailer hitch as standard equipment. The jumper harness
and trailer brake fuse are stored in the glove box.
2 Trailer brakes P. 370
Open the lid of the socket (located next to the
trailer hitch) to expo se the 7-pin trailer
connector.
■Hitches
Read the trailer manufacturer ’s instructions, and select the appropriate draw bar for
the height of the trailer you will be towing.
■Towing Equipment and Accessories
Models with AWD1 Towing Equipment and Accessories
Make sure that all equipmen t is properly installed and
maintained, and that it meets federal, state, province/
territory, and lo cal regulations.
Consult your trai ler maker for prope r installation and
setup of the equipment.
Improper installation and setup can affect the
handling, stability, and br aking performance of your
vehicle.
Consult your traile r sales or rental agency if any other
items are recommended or required for your towing
situation.
The lighting and wiring of tra ilers can vary by type
and brand. If a connector is required, it should only
be installed by a qua lified technician.

■Weight distribution hitches
Your vehicle is designed to tow without the need for a load distributing hitch. If you
wish to use one, please consult 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 brake s: 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 installed in your ve hicle 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.

The 7-pin trailer connector is needed for your trailer lights. When inserting the
connector to the socket, check if the co nnector 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 territories requir e 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 unstab le while driving, trailer stability assist
determines the cause. If the trailer oscill ation is detected as the cause, and the
swaying increases, the system applies the brakes or cont rols engine output to reduce
vehicle speed.
Both the vehicle and trailer brake lights come 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. 375
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. 404

Driving Safely with a Trailer
• Have the trailer properly servic ed 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. 366
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the trailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressure of the trail er tires, including the spare.
• Turn off the Auto Idle Stop syst em using the Auto Idle Stop OFF button. The
trailer weight can affect your vehicle’s brake effectiveness if Auto Idle Stop is
activated on a hill while towing a trailer.
• Drive slower than normal.
• Obey posted speed limits fo r 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.

• Monitor your temperature gauge. If it nears the mark, turn off the climate
control system and reduce speed. Pull to the side of the road safely to cool down
the engine if necessary.
• Shift to the
(S position if the transmission shifts frequently.
When retrieving a boat from the water, we recommend using the sequential shift
mode
(S to utilize the trans missions lower gears.
Towing Your Vehicle
Your vehicle is not designed to be towed behind a motor home. If your vehicle needs
to be towed in an emergency, refe r to the emergency towing information.

uuOff-Highway Driving Guidelines uAvoiding Trouble
Driving
Avoiding Trouble
• Check Out Your Vehicle before you leave the pavement and make sure that all
scheduled maintenance has been comple ted. Pay special attention to the
condition of the tires, an d check the tire pressures.
• Remember the route you choose presents limit s (too steep or bumpy), you have
limits (driving skill and comfort), and your vehicle has limits (traction, stability, and
power). Failing to recognize these limits will likely put you and your passengers in
a hazardous situation.
• Accelerating and Braking should be done slowly and gradually. Trying to start
or stop too fast can cause a loss of traction and you could lose control.
• Avoiding Obstacles and Debris in the road reduces the likelihood of a rollover
or damage to your suspension or other components.
• Driving on Slopes increases your risk of a rollover, particularly if you attempt to
drive across a slope that is too steep. Going straight up or down a slope is usually
the safest. If you can’t clearly see all cond itions or obstacles on a slope, walk it
before you drive it. If there is any doubt whether you can safely pass, don’t try it.
Find another route. If you get stuck when climbing, do not try to turn around.
Back down slowly following the same route you took up the hill.
• Crossing a Stream - Avoid driving through deep water. If you encounter water
in your route (a small stream or large pu ddle, for example), evaluate it carefully
before going ahead. Make sure it is shallow, flowing slowly, and has firm ground
underneath. If you are not sure of the depth or the ground, turn around and find
another route. Driving through deep water can also damage your vehicle. The
water can get into the transmission and differential, diluting the lubricant and
causing an eventual failure. It can also wash the grease out of the wheel bearings.
• If You Get Stuck , carefully go in the direction that you think will get you
unstuck. Do not spin the tires as this will only make things worse and could
damage the transmission. If you are unable to free yourself, your vehicle will need
to be towed. Front and rear tow hooks are provided for this purpose.
