The range of the sensors may
change depending on the shape of
the object, etc.
■Multi-information display, head-up display (if equipped) and
audio system screen
When an object is detected by a sensor, the approximate distanc e to
the object will be displayed on th e multi-information display, audio
system screen, and head-up display (if equipped). (As the dista nce
to the object becomes short, the distance segments may blink.)

■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sen-
sors are operating.
 The buzzer beeps faster as
the vehicle approaches an
object. When the vehicle
comes within approximately
1.0 ft. (30 cm) of the object,
the buzzer sounds continu-
ously.
 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 func-
tion: 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.289)
