Description 

The Parktronic system (PTS) is an ultrasonic measuring system for detecting the distance to an obstacle. It helps the driver to estimate distances to objects in front of and behind the vehicle.

• When selector lever position "D" is engaged and at a speed below 18 km/h the area (A) in front of the vehicle is monitored, when selector lever position "R" or "N" is engaged the area (A) in front of and the area (B) behind the vehicle is monitored. The maximum monitoring range is 100 cm at the front (a) and 120 cm at the rear (b). In areas (c1) and (c2) the Parktronic system (PTS) no longer receives defined values (for technical reasons).
