• The system is deactivated at speeds above 6 mph (10 km/h). It is reactivated at lower speeds.
• Inclement weather or ultrasonic sources such as an automatic car wash, a truck’s compressed-air brakes or a pneumatic drill may affect the function of the system; this may include reduced performance or a false activation.
• The system is not designed to prevent contact with small or moving objects. Always move slowly. The system will not detect small objects below the bumper or on the ground.
• The system may not detect the following objects: fluffy objects such as snow, cloth, cotton, glass-wool, etc.; thin objects such as rope, wire and chain, etc.; or wedge-shaped objects.
• The system may not detect objects at speeds above 3 mph (5 km/h) and may not detect certain angular or moving objects.
• Do not attach stickers (including transparent material), install accessories, or apply anything blocking the sensors. These conditions may reduce the ability of the system.
