Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect objects that are extremely close to
the vehicle.
The range of the sensors may change
depending on the shape of the object, etc.
QMulti-information display, head-up disp
lay (if equipped) and Center Display
When an object is detected by a sensor, the approximate distance to the object will
be displayed on the multi-information display, Center Display, and head-up dis-
play. (As the distance to the object be comes short, the distance segments may
blink.)

QBuzzer 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.222)
