It uses an ultrasonic sensor, which checks the approximate distance to an obstacle. It will inform you of the approximate distance to an obstacle by displaying information on the multi−information display and the screen, and with beeping sounds. 1 Front corner sensors There is one of these installed on each corner of the front bumper, they inspect obstacles and will sound a warning depending on the distance to the obstacle. (See " - Front corner sensors" on page 254.) 2 Rear corner sensors There is one of these installed on each corner of the rear bumper, they inspect obstacles and will sound a warning depending on the distance to the obstacle. (See " - Rear corner sensors" on page 255.) 3 Back sensors There are two of these installed near the center of the rear bumper, they inspect obstacles and will sound a warning depending on the distance to the obstacle. (See " - Back sensors" on page 256.)

Selecting the parking assist−sensor and pushing the ON/OFF button of the satellite switch again will turn the parking assist−sensor off. When you turn on the parking assist−sensor, the indicator light in the instrument cluster comes on and a beep sounds for one second, indicating that the parking assist−sensor is turned on.
