Controls in detail Driving systems Rear sensors Center Corners approx. 48 in (120 cm) approx. 32 in (80 cm) Minimum distance Center Corners approx. 8 in (20 cm) approx. 6 in (15 cm) ! During parking maneuvers, pay special attention to objects located above or below the height of the sensors (e.g. street curbs, painted posts, or trailer hitches etc.). The Parktronic system will not detect such objects at close range and damage to your vehicle or the object may result. Ultrasonic signals from outside sources (e.g. truck air brakes, car wash, or jackhammers) may impair the operation of the Parktronic system. Front sensors Center Corners approx. 40 in (100 cm) approx. 24 in (60 cm) If the system detects an obstacle in this range, all the distance warning segments illuminate and you hear a warning signal. If the obstacle is closer than the minimum distance, the actual distance may no longer be indicated by the system. Warning indicators Visual signals indicate to the driver the relative distance between the sensors and an obstacle. The warning indicators for the front area are located above the left air vents and center air vents in the dashboard. The warning indicator for the rear area is integrated in the rear trim. 236
