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 vehicl e will handle somewhat differently than it
does on pavement. Pay attention to the precau tions 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. 451
•Whenever you drive, make su re 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.

3WARNING
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.

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.

Driving
■Automatic cancellation
The beeper sounds and a message app ears on the MID when ACC with LSF is
automatically canceled. Any of these co nditions may cause the ACC with LSF to
automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor behind the emblem gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with LSF range is too close to your
vehicle.
• When a detected vehicle goes out of th e ACC with LSF range while your vehicle
is stationary.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation can be also triggered by the following
causes. In these cases, the electric park ing brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicl e is stationary.
• The vehicle stops for mo re than 10 minutes.
• The engine is turned off.
• When trailer stability assist is activated.
2 Trailer Stability Assist P. 462
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+/SET/– switch
up.

uuWhen Driving uSuper Handling-All Wheel DriveTM (SH-AWD ®)*
Driving
Super Handling-All Wheel DriveTM (SH-AWD® )*
The system controls and transfers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD ® helps to enhance driving stability, and lets you handle situations like
sli ppe r y sur f a c es , suc h a s o n w e t, i cy , o r sno wy r oa ds , b e tt e r t ha n wh e n dr iv ing wi t h
two wheel drive. However, the system do es not help to enhance braking. Be
precautious about the following:
• It is still your responsibility to drive safely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1Super Handling-All Wheel DriveTM (SH-AWD ®)*
The SH-AWD ® system 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. 2 Tire and Wheel Replacement P. 610
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause damage to the transmission and SH-AWD ®
unit.
If the SH-AWD indicator blinks while driving, it
indicates the differential te mperature is too high. If
this happens, pull to the side of the road when it is
safe, change the gear position to
( P, and idle the
engine until the indicator goes out.

Continued
Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufa cturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inf lated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumina tion of the TPMS low ti re pressure telltale.
Your vehicle has also been eq uipped with a TPMS malfunction
indicator to indicate when the sy stem is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pu mp the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly do wn. On dry pavement, you will need to
press on the brake pedal very hard before th e ABS activates. However, you may feel
the ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS wi ll not be operating. Have
your vehicle checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lockup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with tire chains.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.
