The system is designed to be

used with the same trailer connec-

tion every time. If the ball mount

position is changed or reconfig-

ured or items are added to the

trailer tongue after calibration, re-

calibration may be required.

Guidance mode provides a
“Trailer Direction” arrow that
indicates the direction the trailer
will swing, based on calculations
from the steering wheel angle
information. Guidance mode
provides a “BRAKE Extreme
Trailer Angle” (jackknife) warn-
ing with warning buzzer to alert
the driver that the trailer angle is
near the jackknife condition.

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 tailgate 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 trailer 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. (

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

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.

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.

WARNING

■

Off-road 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.

●

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 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.

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.

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 outside 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.

NOTICE

■

To prevent water damage

Take all necessary safety mea-

sures to ensure that water dam-

age to the engine, hybrid system

or other components does not

occur.

●

Water entering the engine air

intake will cause severe engine

damage.

●

Water entering the automatic

transmission will cause deterio-

ration in shift quality, locking up

of your transmission accompa-

nied by vibration, and ultimately

damage.

●

Water can wash the grease

from wheel bearings, causing

rusting and premature failure,

and may also enter the differen-

tials, transmission and transfer

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 riv-

erbed for firmness. Drive slowly

and avoid deep water.

●

When crossing a river or a pud-

dle, be sure to cross it without

stopping midway. If you stop or

drive at extremely low speeds in

water, water may enter the vehi-

cle and damage the hybrid bat-

tery making the vehicle unable

to be driven.

■

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”.
