Parking and Back-Up Sensor System Operation

The sensors send out ultrasonic waves, receive waves reflected by an obstacle, determine the distance, and use the buzzer and/or multi-information display (MID) to tell the driver that an obstacle is near.

• The front corner sensors work any time the shift lever is shifted out of P position, until the vehicle reaches about 9 mph (15 km/h). They do not come back on until slowing down to about 5 mph (8 km/h) or less.
• The rear corner and rear center sensors are only activated in shift to R position.
• The parking and back-up sensor system is in active with its switch ON.
• The system check is performed each time the parking and back-up sensor switch is turned on with the vehicle in the ON mode.
• The sensors must be free of debris, snow, and ice to work correctly.
