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 lo ad toward the front
of the trailer and 40 % toward the rear.
Readjust the load as needed.
■Towing Load Limits1 Towing 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 the manufacturer), and the
tongue load.
Break-in Period
Avoid towing a trailer during your vehicle’s first 600
miles (1,000 km).
Never exceed the gr oss weight ratings.
Gross weight information 2 Vehicle Specifications P. 350
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.

When Driving
Starting the Engine
1.Make sure the parking brake is applied.
2. Check that the shift lever is in
P, then
depress the brake pedal.
u Although it is possible to start the vehicle

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 altitu des 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 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.
Insert the keyless access remo te into the slot if the
battery in the key is weak. 2 If the Keyless Access Remote Battery is
Weak P. 327
The engine may not start if the keyless access remote
is subjected to strong radio waves.

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 th at you would raise the center of gravity.
• Do not carry heavy cargo on the roof.
Avoid driving in deep water and on flooded roads. This can damage the engine or
cause electrical component failure.
If there is a strong impact with something under the vehicl e, stop in a safe location.
Check the underside of the vehicl e for damage or any fluid leaks.

1Precautions While Driving
NOTICEDo not operate the shift lever while pressing the
accelerator pedal. You could damage the
transmission.
If the ignition switch is turned to ACCESSORY
(q or
LOCK (0*1 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 shift lever in
( N, as you will lose
engine braking (and acce leration) performance.
During the first 600 mile s (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.

problem.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut off if you drive at engine
speeds in or over the ta chometer red zone (engine
speed limit). If this happen s, you may experience a
slight jolt.

Driving
VSA ® (Vehicle Stability Assist), aka ESC (Electronic
Stability Control), System
VSA ® helps to stabilize the vehicle during corn ering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine ou tput and selectively applying the brakes.
When VSA ® activates, you may notice that the
engine does not respon d to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.
■VSA ® Operation
1 VSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability
Control), System
The VSA ® may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® indicator comes on and stays on
while driving, there may be a problem with the
system. While this may no t interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

This button is on the driver side control panel.
To turn the VSA® system on and off, press and
hold it until you hear a beep.
VSA ® will stop and the indicator will come on.
To turn it on agai n, press the (VSA ® OFF)
button until you hear a beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■VSA ® On and Off1 VSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability
Control), System
Without VSA ®, your vehicle will have normal braking
and cornering ability, but it will not have VSA ®
traction and stability enhancement.
In certain unusual condition s when your vehicle gets
stuck in shallow mud or fresh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the VSA ® system is off, the traction control
system is also off. You sh ould only attempt to free
your vehicle with the VSA ® off if you are not able to
free it when the VSA ® is on.
Immediately after freeing yo ur vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® and traction control
systems switched off.
If the low tire pressure/T PMS indicator comes on or
blinks, the VSA ® system comes on automatically. In
this case, you cannot turn the system off by pressing
the button.
You may hear a motor sound coming from the
engine compartmen t while system checks are being
performed immediately after starting the engine or
while driving. This is normal.
