Front & Rear System
Sensors are installed in both front and rear bumpers providing protection whenever you drive forward or in reverse. The system is connected to both reversing light and ACC for power supply. When engine is activated, front sensors start to work. Buzzer turns mute automatically if obstacles keep stationary or move farther. When reverse gear is engaged, the front sensors will stop working and the rear sensors will be activated.
