Controls in detail Driving systems G Warning! Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured. ! Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated crossbars or road curbs). Such objects may not be detected by the system and can damage the vehicle. 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. Range of the sensors 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) If the Parktronic 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 Parktronic system. Warning indicators Visual signals indicate to the driver the relative distance between the sensors and an obstacle. Front sensors Center Corners approx. 40 in (100 cm) approx. 24 in (60 cm) Z 175
