Driving
Drive your vehicle only in areas
where off-road vehicles are permit-
ted to travel.
 Respect private property. Get
owner’s permission before entering
private property.
 Do not enter areas that are closed.
Honor gates, barriers and signs that
restrict travel.
 Stay on established roads. When
conditions are we t, driving tech-
niques should be changed or travel
delayed to prevent damage to
roads.
 AWD models: Avoid driving on very
steep, slippery roads and other sur-
faces, such as sand, where the tires
are liable to lose traction. Your vehi-
cle may not perform as well as con-
ventional AWD on-road vehicles on
these surfaces.
■Additional informatio n for off-road driv-
ing
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the
following organizations.
●State and Local Parks and Recreation
Departments
●State Motor Vehicle Bureau
●Recreational Vehicle Clubs
●U.S. Forest Service and Bureau of Land
Management
WARNING
■Off-road driving precautions
Always observe the following precau-
tions to minimize the risk of death or seri-
ous injury or damage to your vehicle:
●Drive carefully when off the road. Do
not take unnecessary risks by driving in
dangerous places.
●Do not grip the steering wheel spokes
when driving off-road. A bad bump
could jerk the wheel and injure your
hands. Keep both hands and especially
your thumbs on the outside of the rim.
●Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
●After driving through tall grass, mud,
rock, sand, water, et c., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped to the
underbody. Clear of f any such matter
from the underbody. If the vehicle is
used with these materials trapped or
adhering to the underbody, a break-
down 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 compart-
ment may cause seve re damage to the
hybrid system. Water entering the inte-
rior may cause the hybrid battery
stowed under the re ar seats to short
circuit.

2825-3. Using the air conditioning system and defogger
In S-FLOW mode, priority for the air-
flow is given to the front seats, reducing
the airflow and air conditioning effect
on the rear seats.
The following S-FLOW modes are
available:
Automatic S-FLOW mode
When a rear passenger is determined
to be in the vehicle, S-FLOW mode will
be automatically disabled.
The indicator will illuminate on the air con-
ditioning control screen when S-FLOW
mode is enabled.
To enable/disable S-FLOW mode and
enter manual S-FLOW mode, select the S-
FLOW mode switch ( P.280).
Manual S-FLOW mode
When the S-FLOW mode switch is
selected, S-FLOW mode will be manu-
ally enabled/disabled.
The indicator will illuminate on the air con-
ditioning control screen when S-FLOW
mode is enabled.
The system does not determine whether a
passenger is in the rear seats by the open-
ing and closing of a rear door, so S-FLOW mode cannot be automatically disabled.
To automatically disable S-FLOW mode by
opening and closing a rear door, switch to
automatic S-FLOW mode.
■S-FLOW air conditioning control
Operation of S-FLOW mode changes
according to the following conditions.
However, depending on the set tem-
perature and air conditioning load is
high, the operation may not change.
 Driver seat priority:
• When the system determines there is no
passenger in the front passenger seat in
manual S-FLOW mode
• When the system determines there are no passengers in the front passenger
seat and rear seats in automatic S-
FLOW mode
The airflow to the front passenger seat and
rear seat stops and the front passenger
temperature display turns off.
 Front seat priority:
When the system determines there are no
passengers in the rear seats
S-FLOW disabled:
When the system determines there is a
passenger in the rear seats
■Passenger presence determination in S-
FLOW mode
The system determines that there is a pas-
senger in any of the following situations.
If a passenger is judged to be in the vehicle,
the system will retain the judgment for a
certain amount of time after the power
switch is turned off.

3266-1. Maintenance and care
Remove dirt using a water-damp-
ened soft cloth or synthetic chamois.
 Wipe the surface with a dry soft
cloth to remove any remaining
moisture.
■Cleaning the areas with satin-finish
metal accents
The metal areas use a layer of real metal for
the surface. It is necessary to clean them
regularly. If dirty area s are left uncleaned for
long periods of time, they may be difficult to
clean.
■Cleaning the leather
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe off any excess dirt and dust
with a soft cloth dampened with
diluted detergent.
Use a diluted water solution of approxi-
mately 5% neutral wool detergent.
Wring out any excess water from
the cloth and thoroughly wipe off all
remaining traces of detergent.
 Wipe the surface with a dry, soft
cloth to remove any remaining
moisture. Allow the leather to dry in
a shaded and ventilated area.
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
cleaner. The instrument panel’s or
other interior part’s painted surface
may be damaged.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system
may be damaged if water comes into
contact with electrical components such
as the audio system above or under the
floor of the vehicle. Water may also
cause the body to rust.
■When cleaning the inside of the wind-
shield
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(  P.192)
■Cleaning the inside of the rear win-
dow
●Do not use glass cleaner to clean the
rear window, as this may cause dam-
age to the rear window defogger
heater wires or antenna. Use a cloth
dampened with lukewarm water to
gently wipe the window clean. Wipe
the window in strokes running parallel
to the heater wires or antenna.
●Be careful not to scratch or damage
the heater wires or antenna.
■Cleaning the front side windows
Do not use any compound or abrasive
product (e.g., glass cleaner, detergent,
