Front corner sensors✽/Reverse sensors✽
The front corner sensors and reverse sensors are the system that
uses the sonar to recognize the approximate distance between the
vehicle and the obstacle, and that notifies the driver of its presence
by the buzzer and display indica tors when the vehicle speed is
approx. 10 km/h (6 mph) or less.
Sonar positions and types
a Front sonar
The front corner sensors are used to
recognize necessary information.
bRear sonar
The reverse sensors are used to recog-
nize necessary information.
Switching front corner sensors and reverse sensors
(For vehicles with front corner sensors)
Press the switch
Pressing the switch turns on the front
corner sensors or reverse sensors and
lights up the switch-on indicator.
To turn it off, press the switch again.

Sonar’s obstacle recognition range
The recognition areas are shown in
the right figure.
However, if the obstacle is too close
to the sonar, the recognition fails.
Depending on the obstacles’ shape
and conditions, the recognition
range may become shorter, or the
recognition may fail.
⬛Operating conditions
⚫Front corner sensors:
⦁When the engine switch is “ON”
⦁ When the front corner sensors/reverse sensors switch is ON
⦁ When the shift lever is set in other than P, and the vehicle speed is approx.
10 km/h or less
⚫Reverse sensors:
⦁When the engine switch is “ON”
⦁ Vehicles with front corner sensors:
When the front corner sensors/reverse sensors switch is ON
⦁ When the shift lever is set in R, and the vehicle speed is approx. 10 km/h or
less
⚫When an obstacle is recognized with all the activation conditions satisfied
and the parking brake not being applied, the buzzer will sound.
⬛Sonar recognition capabilities
⚫The sonar recognition range is limited to the area around the sonar on the
front side of the vehicle and th e rear bumper of the vehicle.
⚫It takes some time from when the sonar recognizes an obstacle until the
front corner sensors or reverse sensors become activated. If the vehicle gets
too close to the obstacle before the buzzers sounds, the buzzer may not
sound even when the vehicle is traveling at a slow speed.
⚫While the audio or air conditioning system is turned on, the music or fan
noise makes the buzzer sound difficult to hear.
