WARNING
■Cautions regarding the use of
the system
In order for this system to perform
as designed, the vehicle must be
driven safely and the driver must
control the speed to keep it within
operating parameters and to
avoid a collision.
As there is a limit to the degree of
control performance that this sys-
tem can provide, do not overly
rely on this system. The driver is
always responsible for paying
attention to the vehicle’s sur-
roundings and driving safely. This
system does not control braking
(or steering when in Guidance
mode). Driver needs to control
vehicle speed, control braking,
(and steering when in Guidance
mode,) and stop the vehicle to
avoid any collision. Failure to fol-
low this warning could result in
property damage, serious injury
or death.
■When using the Trailer
Backup Guide
For proper system performance,
observe the following precautions.
Failure to do so may lead to an
accident resulting in property
damage, serious injury, or death.
●Keep the tailgat e fully latched.
●Keep the rear camera clean at
all times.
●Do not change the installation
position or direction of the rear
camera or remove it.
●Do not modify the trailer hitch
light. (→P.386)
●Make sure nothing can obstruct
the rear camera view of the
trailer.
The system is designed to oper-
ate in various weather and lighting
conditions and on different ground
surfaces (asphalt , grass, gravel,
etc.), however performance can
still be affected by various envi-
ronmental factors (e.g. shadow
passing over the tr ailer or dimin-
ished contrast between trailer and
the ground leading to trailer
detection being lost, etc.) so
always drive carefully, remain
alert and aware of your surround-
ings, and do not overly rely on the
system.

When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. ( P.358)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.97)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. When using the air condi-
tioning system, etc., the hybrid
battery (traction battery) power
is consumed. 
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic
reports before leaving and avoid
delays as much as possible.
When driving in a traffic jam,
gently release the brake pedal
to allow the vehicle to move for-
ward slightly while avoiding

overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consump-
tion.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to
release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.
Use the air conditioning only
when necessary. Doing so can
help reduce excessive gasoline
consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing so
will help to reduce the burden on
the air conditioning system and
reduce fuel consumption as
well.
In winter: Because the gasoline
engine will not automatically cut
out until it and the interior of the
vehicle are warm, it will con-
sume fuel. Also, fuel consump-
tion can be improved by
avoiding overuse of the heater.Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically
when cold, warming up the
engine is unnecessary. More-
over, frequently driving short
distances will cause the engine
to repeatedly warm up, which
can lead to excess fuel con-
sumption.

 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
ordinary passenger cars any
more than low-slung sports
cars are designed to perform
satisfactorily under off-road
conditions. Therefore, sharp
turns at excessive speeds
may cause the vehicle to roll-
over. When driving your vehicle off-
road, please observe the follow-
ing precautions to ensure your
driving enjoyment and to help
prevent the closure of areas to
Off-road precautions
This vehicle belongs to the
utility vehicle class, which
has higher ground clear-
ance and narrower tread in
relation to the height of its
center of gravity to make it
capable of performing in a
wide variety of off-road
applications.
Off-road vehicle features
WARNING
■Off-road vehicle precautions
Always observe t he following pre-
cautions to minim ize 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 operat e this vehicle
correctly may result in loss of
control or vehicle rollover caus-
ing death or serious injury.
●Avoid loading any items on the
roof that will raise the vehicle’s
center of gravity.
●Always slow down in gusty
crosswinds. Because of its pro-
file and higher ce nter 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.

off-road 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 property.
 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.
■Additional information for
off-road driving
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.

Bureau of Land Management
WARNING
■Off-road driving precautions
Always observe the following pre-
cautions to minimize the risk of
death, serious 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 ou tside of the
rim.
●Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
●After driving through tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on 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.
●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 fasten their seat belts
whenever the vehicle is moving.
●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.
