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.266)Multi-information display *2

Operation of the RCTA function
The RCTA function uses rear side radar sensors to detect vehicles approaching
from the right or left at the rear of the ve hicle and alerts the driver of the presence
of such vehicles by flashing the outside rear view mirror indi cators and sounding a
buzzer.

Cautions regarding the use of the
function
The driver is solely responsible for safe
driving. Always driv e safely, taking care
to observe your surroundings.
The RCTA function is only a supplemen-
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 RCTA function operates when all of the
following conditions are met:
●
