Utility vehicle precautions

This vehicle belongs to the utility vehicle class, which has higher ground clearance
and narrower tread in relation to the height of its center of gravity.

Utility vehicle feature

●

Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. 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 cornering at the same speeds as ordinary passenger
cars any more than low-slung sports cars designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may cause
rollover.

WARNING

■

Utility vehicle precautions

Always observe the following precautions to minimize the risk of death or serious injury
or damage to your vehicle:

●

In a rollover crash, an unbelted person is significantly more likely to die than a person
wearing 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 causing death or serious
injury.

●

Loading cargo on the roof luggage 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 vehicle rollover due
to failure to operate this vehicle correctly.

●

Always slow down in gusty crosswinds. Because of its profile 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 sideways much
more easily than forward or backward.

Off-road driving

Your vehicle is not designed to be driven off-road. However, in the event that
off-road driving cannot be avoided, please observe the following precautions to
help avoid the areas prohibited to vehicles.

●

Drive your vehicle only in areas where off-road vehicles are permitted to travel.

●

Respect private property. Get owner’s permission before entering private prop-
erty.

●

Do not enter areas that are closed. Honor gates, barriers and signs that restrict
travel.

●

Stay on established roads. When conditions are wet, driving techniques should
be changed or travel delayed to prevent damage to roads.

●

Avoid driving on very steep, slippery roads and other surfaces, such as sand,
where the tires are liable to lose traction. Your vehicle may not perform as well
as conventional AWD on-road vehicles on these surfaces.

WARNING

●

After driving through tall grass, mud, rock, sand, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped to the underbody. Clear
off any such matter from the underbody. If the vehicle is used with these materials
trapped or adhering to the underbody, a breakdown or fire could occur.

●

When driving off-road or in rugged 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 water damage

Take all necessary safety measures to ensure that water damage to the hybrid battery
(traction battery), hybrid system or other components does not occur.

●

Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery stowed under the
rear seats to short circuit.

●

Water entering the hybrid transmission and rear electric motor (traction motor) will
cause deterioration in transmission quality. The malfunction indicator may come on,
and the vehicle may not be drivable.

●

Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the hybrid transmission 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 driving

●

Sand and mud that has accumulated around brake discs may affect braking efficiency
and may damage brake system components.
