■Parking Support Brake function
(rear pedestrians) (if equipped)
A rear camera sensor is used to detect
pedestrians in the detection area
behind the vehicle when backing up.
(  P.244)
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 in to 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.
