Note on sensor positioning
The proper functioning of the PDC depends on the position and alignment of the sensors. Therefore, it is important to check certain conditions before installation. The area inside the bumper must provide sufficient depth and space for proper installation. The sensors must be mounted at a height of 35 to 65 cm on the bumper. The sensor surface must be aligned vertically to the ground. The distance between sensors can vary between 30 to 70 cm and should be evenly distributed. The distances of the outer sensors must be equal.
Handling note
For vehicles equipped with a tow hitch, the PDC system should not be activated when towing a trailer. In some cases, smaller objects such as bushes, poles, or posts may not be detected by the system, which can lead to damage without driver intervention.
Installation note
Please connect the positive terminal of the speaker to the ignition line (KL15) and not to constant power to avoid deep discharge of the vehicle battery. Installation of sensors in metal bumpers is not possible.
Safety note
Responsibility during parking and maneuvering lies solely with the driver. The electronic parking aid is a driver assistance system but cannot replace driver attention. Due to physical limitations, ultrasonic measurement may result in detection gaps, especially with poor sound reflection. Therefore, the assessment of obstacles always remains the driver’s responsibility.
