• 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 mode
(S to utilize the transmissions lower gears.
Towing Behind a Motorhome
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.

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 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 (Honda 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.
■Driving Guidelines for Your Utility Vehicle
■In Rain
■Other Precautions
1 Precautions While Driving
NOTICE
Do not select a shift button 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 restor ed. 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 select
( N while driving as you will lose engine
braking (and accelera tion) 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)
after purchasing your new vehicle or replacing the
brake pads or rotors, to allow for proper break-in.

uuWhen Driving uAuto Idle Stop
408
Driving
The vehicle stops with the transmission in (D and the brake pedal depressed.
When you put the transmission into
(P, the Auto Idle Stop continues to operate,
even if the brake pedal is released. u If you depress the brake pedal, the engine may automatically restart.
■Auto Idle Stop does not activate when:
• The Auto Idle Stop OFF button is pressed.
• The driver’s seat belt is not fastened.
• The engine is not adequately warmed up or coolant temperature is high.
• The transmission fluid temperature is low or high.
• The vehicle comes to a stop again befo re the vehicle speed reaches 3 mph (5
km/h) after the engine starts.
• The vehicle is stopped on a steep incline.
• The transmission is in a position other than
(D.
• The engine is started with the hood open.
u Turn off the engine. Close the hood before you restart the engine to activate
Auto Idle Stop.
• The battery charge is low.
• The internal temperature of the battery is 14°F (−10°C) or less.
• The climate control system is in use, an d the outside temperature is below −4°F
(−20°C) or over 104°F (40°C).
• The climate control system is in us e, and the temperature is set to Hi or Lo.
• is ON (indicator on).
• The Intelligent Traction Management is set to Snow, Mud

*1: If the message Maintenance Due Now does not appear more than 12 months after the display
is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty in the first column on page 581.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and from diesel-powered vehicles, replace every 15,000 miles (24,000 km).

●Inspect fuel lines and connections#
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperatures. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder
TM. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at every 30,000 miles (48,000 km) or 2 years.
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under
-20°F, -29°C), or towing a trailer, replace every 60,000 miles (U.S.) / 100,000 km (Canada).
*6: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder
TM. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

uuIndicator, Comin g On/BlinkinguIf the Brake System Indicator (Red) Comes On
Handling the Unexpected
If the Brake System Indicator (Red) Comes On
■Reasons for the indicator to come on
• The brake fluid is low.
• There is a malfunction in the brake system.
■What to do when the indicator comes on while driving
Depress the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate acti on. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the Electric Power Steeri ng (EPS) System Indicator
Comes On
■Reasons for the indicator to come on
Comes on when there is a pr oblem with the EPS system.
■What to do when the indicator comes on
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle
inspected by a dealer.
1 If the Brake System Indicator (Red) Comes On
Have your vehicle re paired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe plac e. If necessary downshift
the gears.
If the brake system indicator (red) and ABS indicator
come on simultaneously , the electronic brake
distribution system is not wo rking. This can result in
vehicle instability under sudden braking.
Have your vehicle inspecte d by a dealer immediately.
If both red and amber brake system indicators come
on, stop the vehicle in a safe place and have it
inspected by a dealer immediately.U.S.
