Driving
*: If equipped
The system can detect the fol-
lowing as detectable objects.
(Detectable objects differ
depending on the function.)
Static Objects Front and Rear
of the vehicle ( P.270)
 Moving Vehicles Rear of the
Vehicle ( P.272)
PKSB (Parking Sup-
por t Brake)*
The PKSB (Parking Support
Brake) consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
PKSB (Parking Support
Brake) system
WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may n ot operate.
The detection cap abilities of sen-
sors 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 PKSB
(Parking Support Brake) system
is designed to provide support
to lessen the severity of colli-
sions. However, it may not oper-
ate in some situations.
●The PKSB (Parki ng Support
Brake) system is not designed
to stop the vehicle completely.
Additionally, even if the system
has stopped the vehicle, it is
necessary to depress the brake
pedal immediately 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.

2664-5. Using the driving support systems
The PKSB (Parking Support
Brake) system can be
enabled/disabled on of the
multi-information display.
(P.449)
When the PKSB (Parking Sup-
port Brake) function is off, the
driving assist information indica-
tor ( P.74) will illuminate.
When turned OFF (disabled), the
PKSB (Parking Supp ort Brake) will
be disabled and will not be enabled
until the setting is changed to ON
again in multi-information display.
(The function will no t be reenabled
by operating the engine switch.)
If the engine output restriction con-
trol or brake control operates, a
buzzer will sound and a message
will be displayed on the multi-infor-
WARNING
■When to disable the PKSB
(Parking Support Brake) sys-
tem
In the following situations, disable
the PKSB (Parking Support
Brake) as the system may oper-
ate even though there is no possi-
bility 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 additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●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 a tire chains or compact
spare tire is used
●When your vehicle is towing a
trailer or during emergency tow-
ing
■Precautions for the suspen-
sion
Do not modify the suspension of
the vehicle. If the height or tilt of
the vehicle is c hanged, the sen-
sors may not be able to detect
detectable objects and the system
may not operate correctly, possi-
bly leading to an accident.

If the PKSB (Parking Support Brake) determines that a collision with
a detected object is possible, the engine output will be restri cted to
restrain any increase in the vehicle speed. (Engine output restriction
control: See figure 2.)
Additionally, if the accelerator pedal continues to be depresse d, the
brakes will be applied automatica lly to reduce the vehicle speed.

■If the PKSB (Parking Support
Brake) has operated
If the vehicle is stopped due to oper-
ation of the PKSB (P arking Support
Brake), the PKSB (P arking Support
Brake) will be disabled and the driv-
ing assist informa tion indicator will
illuminate. If the PKSB (Parking
Support Brake) op erates unneces-
sarily, brake control can be canceled
by depressing the brake pedal or
waiting for approximately 2 sec-
onds for it to automatically be can-
celed. Then, the vehicle can be
operated by depress ing the acceler-
ator pedal.
■Re-enabling the PKSB (Parking
Support Brake) system
To re-enable the PKSB (Parking
Support Brake) when it has been
disabled due to operation of the
PKSB (Parking Support Brake),
either enable the system again (
 P.266), or turn the engine switch
off and then back to ON.
Additionally, if a ny of the following
conditions are m et, the system will
be re-enabled automatically and the
driving assist inf ormation indicator
will turn off:
●The P shift position is selected
●The object is no longer detected in
the traveling direction of the vehi-
cle
●The traveling direction of the vehi-
cle changes

2704-5. Using the driving support systems
If the sensors detect a static object, such as a wall, in the travelling
direction of the vehicle and the system determines that a collision
may occur due to the vehicle suddenly moving forward due to an
accidental accelerator pedal operation, the vehicle moving the unin-
tended direction due to the wrong shift position, or while park ing or
traveling at low speeds, the system will operate to lessen the impact
with the detected static object and reduce the resulting damage .
The system operates in the follow ing situations when a static object
is detected in the traveling direction of the vehicle.
■When traveling at a low speed and the brake pedal is not
depressed, or is depressed late
■When the accelerator pedal is depressed excessively

traveling direction of the vehicle.
■Detection range
The detection range of the system
differs from the detection range of
the intuitive parking assist. ( P.263) Therefore, even if the intuitive park-
ing assist detects an object and pro-
vides a warning, the PKSB (Parking
Support Brake) may not start oper-
ating.
■Situations in which the system
may not operate properly
 P.261
■Situations in which the system
may operate even if there is no
possibility of a collision
 P.262
If a rear radar sensor detects a vehicle approaching from the right or
left at the rear of the vehicle and the system determines that the pos-
sibility of a collision is high, this function will perform bra ke control to
reduce the likelihood of an impact with the approaching vehicle .
This function will operate in situations such as the following if a vehi-
cle is detected in the traveling direction of the vehicle.
■When reversing, a vehicle is approaching and the brake pedal
is not depressed, or is depressed late
