PKSB (Parking Support
Brake)

The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that the possibility of a colli-
sion with a detected object is high, a
warning operates to urge the driver
to take evasive action. If the system
determines that the possibility of a
collision with a detected object is
extremely high, the brakes are
automatically applied to help avoid
the collision or help reduce the
impact of the collision.

WARNING

■

Cautions regarding the use of the

system

Do not overly rely on the system, as

doing so may lead to an accident.
Always drive while checking the safety of

the surroundings of the vehicle.
Depending on the vehicle and road con-

ditions, weather, etc., the system may not

operate.
The detection capabilities of sensors and

radars are limited. Always drive while

checking the safety of the surroundings

of the vehicle.

●

The driver is solely responsible for safe

driving. Always drive carefully, taking

care to observe your surroundings.

The Parking Support Brake system is

designed to provide support to lessen

the severity of collisions. However, it

may not operate in some situations.

●

The Parking Support Brake system is

not designed to stop the vehicle com-

pletely. Additionally, even if the system

has stopped the vehicle, it is necessary

to depress the brake pedal immedi-

ately as brake control will be canceled

after approximately 2 seconds.

●

It is extremely dangerous to check the

system operations by intentionally

driving the vehicle into the direction of

a wall, etc. Never attempt such actions.

■

When to disable the Parking Support

Brake

In the following situations, disable the

Parking Support Brake as the system

may operate even though there is no

possibility of a collision.

●

When inspecting the vehicle using a

chassis roller, chassis dynamo or free

roller.

●

When loading the vehicle onto a boat,

truck or other transport vessel.

●

If the suspension has been modified or

tires of a size other than specified are

installed.

●

If the front of the vehicle is raised or

lowered due to the carried load.

●

When equipment that may obstruct a

sensor is installed, such as a towing

eyelet, bumper protector (an addi-

tional trim strip, etc.), bicycle carrier,

or snow plow.

●

When using automatic car washing

devices.

●

If the vehicle cannot be driven in a sta-

ble manner, such as when the vehicle

has been in an accident or is malfunc-

tioning.

●

When the vehicle is driven in a sporty

manner or off-road.

●

When the tires are not properly

inflated.

●

When the tires are very worn.

●

When tire chains, a compact spare tire

or an emergency tire puncture repair

kit are used.

●

During emergency towing.

When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.

The Eco-friendly driving is possible by
keeping the indicator of Hybrid System
Indicator within Eco area. (

Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic, etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed.



Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.



Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.

Make sure to operate the brakes gen-
tly and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.

Repeated acceleration and decelera-
tion, 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 forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.

4-6. Driving tips

Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently 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 tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem 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 consume fuel. Also, fuel consump-
tion can be improved by avoiding
overuse of the heater.

Make sure to check the tire inflation
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
season.

Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
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.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.



Park the vehicle and move the shift
lever to P without setting the park-
ing brake. The parking brake may
freeze up, preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly lead-
ing to an accident.

When the parking brake is in automatic
mode, release the parking brake after shift-
ing the shift lever to P. (

WARNING

■

Utility vehicle precautions

Always observe the following precau-

tions to minimize the risk of death or seri-

ous 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 maneu-

vers, if at all possible.

Failure to operate this vehicle cor-

rectly may result in loss of control or

vehicle rollover causing death or seri-

ous injury.

●

Loading cargo on the roof luggage

carrier 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 con-

trol or vehicle rollover due to failure to

operate this vehicle correctly.

●

Always slow down in gusty crosswinds.

Because of its profile and higher cen-

ter of gravity, your vehicle is more sen-

sitive 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 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, 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 vehi-

cle 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 compart-

ment 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.

272

4-6. Driving tips

NOTICE

●

Water entering the hybrid transmis-

sion and rear electric motor (traction

motor) will cause deterioration in

hybrid transmission quality. The mal-

function 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 sys-

tem 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 “Warranty and Services
