■Buzzer operation and distance to
an object
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an object. When the
vehicle comes within the following
distance of the object, the buzzer
sounds continuously:
Approximately 1.0 ft. (30 cm)
When 2 or more objects are
detected simultaneously, the buzzer
sounds for the nearest object. If one
or more objects come within
approximately 1.0 ft. (30 cm) of the
vehicle, the buzzer will repeat a long
tone, followed by fast beeps.
 Automatic buzzer mute function: After a buzzer begins sounding, if
the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. [30 cm] or less,
this function will not operate.)
The buzzer sounds volume can be
adjusted. ( P.214)

tary function which alerts the driver that a
vehicle is approaching from the right or
left at the rear of the vehicle. As the
RCTA function may not function cor-
rectly under certain conditions, the
driver’s own visual confirmation of safety
is necessary. Over reli ance on this func-
tion may lead to an accident resulting
death or serious injury.

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 or
pedestrian is high, a warning oper-
ates to urge the driver to take eva-
sive action. If the system
determines that the possibility of a
collision with a detected object or
pedestrian is extremely high, the
brakes are automatically applied to
help avoid the collision or help
reduce the impact of the collision.
