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.

Your trailer lighting connector is located behind the left side panel in the cargo area.
Each pin’s purpose and wiring color code are shown in the image.

When using a non-Acura trailer lighting harness and converter, get the connector
and pins for your vehicle from a dealer.

•

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 pressures of the trailer tires, including the spare.

•

Turn off the Auto Idle Stop system 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.

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 other challenging off-highway 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. 409

•

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.

WARNING

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.

Avoiding Trouble

Driving

Avoiding Trouble

•

Check Out Your Vehicle

before you leave the pavement and make sure that all

scheduled maintenance has been completed. Pay special attention to the
condition of the tires, and check the tire pressures.

•

Remember

the route you choose presents limits (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 conditions 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 puddle, 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 tow hooks are provided for this purpose.

Starting the Engine

Keep your foot firmly on the brake pedal when
starting the engine.

The engine is harder to start in cold weather and in thinner
air found at altitudes above 8,000 feet (2,400 meters).

When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear defogger in order to reduce
battery drain.

If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. Consult a dealer for details.

If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.

Driving

Precautions While Driving

Utility vehicles have a significantly higher rollover rate than other types of vehicles.
To prevent rollovers or loss of control:

•

Take corners at slower speeds than you would with a passenger vehicle.

•

Avoid sharp turns and abrupt maneuvers whenever possible.

•

Do not modify your vehicle in any way that you would raise the center of gravity.

•

Do not carry heavy cargo on the roof.
Never carry more than 165 lbs (75 kg) of cargo on the roof rack (Acura accessory).

Avoid driving in deep water and on flooded roads. This can damage the engine or
driveline, or cause electrical component failure.

If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.

Precautions While Driving

NOTICE

Do not change the transmission while pressing the
accelerator pedal. You could damage the transmission.

NOTICE

If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in the
full left or right position for a while, the electric power
steering (EPS) system heats up. The system goes into a
protective mode, and limits its performance. The
steering wheel becomes harder and harder to operate.
Once the system cools down, the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.

If the power mode is set to ACCESSORY while
driving, the engine will shut down and all steering
and brake power assist functions will stop, making it
difficult to control the vehicle.

Do not put the transmission into

(

N

, as you will lose

engine braking (and acceleration) performance.

During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as not to damage the engine or powertrain.

Avoid hard braking for the first 200 miles (300 km). You
should also follow this when the brake pads are replaced.
