Function
To switch on, press the parking aid button (E266) or engage the reverse gear when the ignition is switched on. To switch off, press the parking aid button (E266) again (the parking aid indicator lamp (K136) goes out) or drive faster than approximately 15 km/h.
A short signal tone will sound and the parking aid indicator lamp (K136) will come on when the parking aid is ready. If the system recognized a malfunction, the long tone will sound for 5 seconds and the parking aid indicator lamp (K136) will blink.
During the distance measurement, the pauses between chime impulses get shorter as the gap between vehicles gets smaller. At proximity of less than 30 cm, a continuous tone is heard. Exception: Driving parallel with a wall = no warning
DTC Recognition and Display
The parking aid system is capable of On Board Diagnostic.
Use the Vehicle Diagnosis, Testing and Information System (VAS 5051B) under "Guided Fault Finding".
Perform output Diagnostic Test Mode (DTM) to test the entire parking aid system. Refer to=> [ Parking Aid System Output Diagnostic Test Mode (DTM) ] Parking Aid System Output Diagnostic Test Mode (DTM).
