Driving
Towing a Trailer
Towing Preparation
Your vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelin es. Check the load limits before driving.
■Total trailer weight
Maximum allowable weight of the trailer,
cargo, and everything in or on it must not
exceed 1,500 lbs (680 kg). Towing loads in
excess of this can seriously affect vehicle
handling and performance and can damage
the engine and drivetrain.
■Tongue load
The weight of the tongue with a fully loaded
trailer on the hitch should be approximately
10% of the total trailer weight.
• Excessive tongue load reduces front tire
traction and steering control. Too little
tongue load can make the trailer unstable
and cause it to sway.
• To achieve a proper tongue load, start by
loading 60% of the load toward the front
of the trailer and 40% toward the rear.
Readjust the lo ad as needed.
■Towing Load Limits1Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by th e manufacturer), and the
tongue load.
Break-in Period
Avoid towing a trailer duri ng your vehicle’s first 600
miles (1,000 km).
Never exceed the gross weight ratings.
Gross weight information 2 Vehicle Specifications P. 432
3WARNING
Exceeding any load limit or improperly
loading your vehicle and trailer can cause a
crash in which you can be seriously hurt or
killed.
Check the loading of your vehicle and
trailer carefully before starting to drive.

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. 263
•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.
• Monitor your temperature gauge. If it nears the red (Hot) 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.

3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.
1 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 de fogger 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. Cons ult 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.
Bring the keyless access remote close to the ENGINE
START/STOP button if the batte ry in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 415
The engine may not start if the keyless access remote
is subjected to strong radio waves.
You do not need to hold the ENGINE START/STOP
button to start the engine.
If the engine does not start, wait at least 30 seconds
before trying again.

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 yo u would with a passenger vehicle.
• Avoid sharp turns and abrupt maneuvers whenever possible.
• Do not modify your vehicle in any way th at you would raise the center of gravity.
• Never carry more than 165 lbs (75 kg) of ca rgo on the roof rack (Acura accessory).
Avoid driving in deep water and on flooded roads. This can damage the engine,
driveline, or cause electrical component failure.
If there is a strong impact with something un der the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.

■Other Precautions
1 Driving Guidelines for Your Utility Vehicle
Failure to operate your vehicle correctly might result
in a crash or a rollover. 2 Important Handling Information P. 28
1Precautions While Driving
NOTICE
Do not operate the shift lever 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 on 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 functi ons will stop, making it
difficult to control the vehicle.
Do not put the shift lever in
( N, as you will lose
engine braking (and acce leration) 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.

uuWhen Driving uAutomatic Transmission
Driving
Automatic Transmission
The engine runs at a higher id le speed and creeping increases.
Keep the brake pedal firmly depressed when stopped.
Quickly depressing the accelerator pedal while driving uphill may cause the
transmission to drop to a lower gear, unexp ectedly increasing vehicle speed. Depress
the accelerator pedal carefully, especi ally on slippery roads and curves.
