■If “Parking Support Brake Unavailable”
is displayed on th e multi-information
display
●If this message is di splayed only when the
R shift position is selected, the rear cam-
era lens may be dirty. Clean the camera
lens. If this message is displayed when the
shift position is any position other than R,
a sensor on the front or rear bumper may
be dirty. Clean the sensors and their sur-
rounding area on the bumpers.
●Initialization may not have been per-
formed after a battery terminal was dis-
connected and reconnected. Initialize the
system. ( P.288)

ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more.
Additionally, for vehicles with the Parking
Support Brake function, turn the steering
wheel fully to the left and right with the vehi-
cle stopped.
*: If equipped
This function will operate in situations
such as the following if an 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
Parking Support Brake func-
tion (static objects)*
If the sensors detect a static object,
such as a wall, in the travelling
direction of the vehicle and the sys-
tem determines that a collision may
occur due to the vehicle suddenly
moving forward due to an acciden-
tal accelerator pedal operation, the
vehicle moving the unintended
direction due to the wrong shift
position being selected, or while
parking or traveling at low speeds,
the system will operate to lessen
the impact with the detected static
object and reduce the resulting
damage.
Examples of function operation

2964-5. Using the driving support systems

Parking Support Brake func-
tion (rear pedestrians)*
If the rear camera sensor detects a
pedestrian behind the vehicle while
backing up and the system deter-
mines that the possibility of collid-
ing with the detected pedestrian is
high, a buzzer will sound. If the sys-
tem determines that the possibility
of colliding with the detected
pedestrian is extremely high, the
brakes will be applied automatically
to help reduce the impact of the
