many factors such as the condi-

tions of the vehicle, trailer, road

surface and driving environment,

the Trailer Sway Control system

may not be effective. Refer to

your trailer owner’s manual for

information on how to tow your

trailer properly.

■

If trailer sway occurs

Observe the following precau-

tions.

Failing to do so may cause death

or serious injury.

●

Firmly grip the steering wheel.

Steer straight ahead. Do not try

to control trailer swaying by

turning the steering wheel.

●

Begin releasing the accelerator

pedal immediately but very

gradually to reduce speed.

to the driving conditions:



Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.



To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.



Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, vehicle’s roof,
chassis, around the tires or on
the brakes.



Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle.

Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.



Turn automatic mode of the
parking brake off. Otherwise,
the parking brake may freeze
and not be able to be
released automatically.

Also, avoid using the following
as the parking brake may
operate automatically, even if
automatic mode is off.

• Brake hold system
• Remote parking function



Park the vehicle and shift the
shift position to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels.
Failure to do so may be dan-
gerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an
accident.

Specific design characteris-
tics give it a higher center of
gravity than ordinary passen-
ger cars. This vehicle design
feature causes this type of
vehicle to be more likely to
rollover. And, utility vehicles
have a significantly higher
rollover rate than other types
of vehicles.



An advantage of the higher
ground clearance is a better
view of the road allowing you
to anticipate problems.



It is not designed for corner-
ing at the same speeds as

applications.

Utility vehicle feature

WARNING

■

Utility vehicle precautions

Always observe the following pre-

cautions to minimize the risk of

death, serious injury or damage to

your vehicle:

●

In a rollover crash, an unbelted

person is significantly more

likely to die than a person wear-

ing a seat belt. Therefore, the

driver and all passengers

should always fasten their seat

belts.

●

Avoid sharp turns or abrupt

maneuvers, if at all possible.

Failure to operate this vehicle

correctly may result in loss of

control or vehicle rollover caus-

ing death or serious injury.

●

Loading cargo on the roof lug-

gage carrier (if equipped) will

make the center of the vehicle

gravity higher. Avoid high

speeds, sudden starts, sharp

turns, sudden braking or abrupt

maneuvers, otherwise it may

result in loss of control or vehi-

cle rollover due to failure to

operate this vehicle correctly.

●

Always slow down in gusty

crosswinds. Because of its pro-

file and higher center of gravity,

your vehicle is more sensitive to

side winds than an ordinary

passenger car. Slowing down

will allow you to have better

control.

●

Do not drive horizontally across

steep slopes. Driving straight up

or straight down is preferred.

Your vehicle (or any similar off-

road vehicle) can tip over side-

ways much more easily than

forward or backward.

5-5. Driving tips

WARNING

●

When driving off-road or in rug-

ged terrain, do not drive at

excessive speeds, jump, make

sharp turns, strike objects, etc.

This may cause loss of control

or vehicle rollover causing

death or serious injury. You are

also risking expensive damage

to your vehicle’s suspension

and chassis.

NOTICE

■

To prevent the water damage

Take all necessary safety mea-

sures to ensure that water dam-

age to the traction battery, EV

system or other components does

not occur.

●

Water entering the motor com-

partment may cause severe

damage to the EV system.

●

Water entering the transmis-

sion will cause deterioration in

transmission quality. The mal-

function indicator may come on,

and the vehicle may not be driv-

able.

●

Water can wash the grease

from wheel bearings, causing

rusting and premature failure,

and may also enter the tran-

saxle case, reducing the gear

oil’s lubricating qualities.

■

When you drive through

water

If driving through water, such as

when crossing shallow streams,

first check the depth of the water

and the bottom of the riverbed for

firmness. Drive slowly and avoid

deep water.

■

Inspection after off-road driv-

ing

●

Sand and mud that has accu-

mulated around brake discs

may affect braking efficiency

and may damage brake system

components.

●

Always perform a maintenance

inspection after each day of off-

road driving that has taken you

through rough terrain, sand,

mud, or water. For scheduled

maintenance information, refer

to the “Scheduled Maintenance

Guide” or “Owner’s Manual

Supplement”.
