Vehicles with 225/60R18 tires
Tire chains cannot be mounted on the
225/60R18 tires.
Snow tires should be used instead.
Regulations regarding the use of tire
chains vary depending on location and
type of road. Always check local regu-
lations before installing chains.
■Tire chain installation
Observe the following precautions when
installing and removing chains:
●Install and remove tire chains in a safe
location.
●Install tire chains on the front tires only.
Do not install tire chains on the rear tires.
●Install tire chains on fr ont tires as tightly as
possible. Retighten chains after driving 1/
4 - 1/2 mile (0.5 - 1.0 km).
●Install tire chains following the instruc-
tions provided with the tire chains.
 Specific design characteristics give
it a higher center of gravity than
ordinary passenger cars. This vehi-
cle design feature causes this type
of vehicle to be more likely to roll-
over. Utility vehicles have a signifi-
cantly higher rollover rate than
other types of vehicles.
 It is not designed for cornering at
the same speeds as ordinary pas-
senger cars any more than low-
slung sports cars designed to per-
form satisfactorily under off-road
conditions. Therefore, sharp turns at
excessive speeds may cause roll-
over.

■Utility vehicle precautions
Always observe the following precau-
tions to minimize the risk of death or seri-

the driver and all passengers should
always fasten their seat belts.

Maintenance and care
 Remove dirt and dust using a vac-
uum cleaner. Wipe dirty surfaces
with a cloth dampened with luke-
warm water.
 If dirt cannot be removed, wipe it off
with a soft cloth dampened with
neutral detergent diluted to approx-
imately 1%. Wring out any excess
water from the cloth and thoroughly
wipe off remaining traces of deter-
gent and water.
■Shampooing the carpets
There are several commercial foaming-type
cleaners available. Use a sponge or brush
to apply the foam. Rub in overlapping cir-
cles. Do not use water. Wipe dirty surfaces
and let them dry. Excellent results are
obtained by keeping the carpet as dry as
possible.
■Handling the seat belts
Clean with mild soap and lukewarm water
using a cloth or spon ge. Also check the
belts periodically for excessive wear, fraying
or cuts.
■Front side windows with UV protective
coating (vehicles with UV protective
coating)
The front side windows have UV protective
coating. To prevent any damage to the UV
protective coating, observe the following:
●If the windows are dirty, gently wipe them
with a cloth soaked in water or lukewarm
water as soon as possible.
●If the windows are very dirty, do not open
and close them repeatedly.Cleaning and protecting the
vehicle interior
Perform cleaning in a manner
appropriate to each component
and its material.
Protecting the vehicle interior
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehi-
cle, such as on the floor, in the hybrid
battery (traction battery) air vents, and
in the luggage compartment.
Doing so may cause the hybrid battery,
electrical components, etc. to mal-
function or catch fire.
●Do not get any of the SRS components
or wiring in the vehicle interior wet.
(  P.32)
An electrical malfunction may cause
the airbags to deploy or not function
properly, resulting in death or serious
injury.
■Cleaning the interior (especially
instrument panel)
Do not use polish wax or polish cleaner.
The instrument panel may reflect off the
windshield, obstructin g the driver’s view
and leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of
detergent, as they may discolor the
vehicle interior or cause streaks or
damage to painted surfaces:
• Non-seat portions: Organic sub- stances such as benzene or gasoline,
alkaline or acidic solutions, dye, and
bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●Do not use polish wax or polish
