General Information
• Familiarity with the function and operation of the parallel parking assistance is essential when addressing complaints.
• Refer to the Owner's Manual.
Function
The parallel parking assistance assists the driver when backing up to parallel park in a spot on the driver or passenger side. When parallel parking assistance is activated and the vehicle is moving forward less than 35 km/h, ultrasonic sensors scan for a suitable parking space. When a suitable parking space is found, the parallel parking assistance directs the driver to drive past the space until the vehicle will be able to parallel park in one movement. When reverse gear is engaged, the parallel parking assistance controls the Electronic Power Steering = Electro-Mechanical Power Steering) (EPS) which steers the vehicle along a calculated route into the parking space. During this time, the driver still controls the accelerator, the pedals (accelerator, clutch and brake) and determines the vehicle parking speed. During the parking process, the parallel parking assistance sensors and the parking distance sensors are used.
The parking process with the parallel parking assistance will be interrupted under the following conditions:
• The Parallel Parking Assistance Button (E581) switches off the parallel parking assistance.
• The ignition is switched off
• The parking speed is too high (faster than 7 km/h)
• The driver grabs the steering wheel during the parking process
• The vehicle is shifted out of reverse gear
• The time limit for the vehicle standing still is exceeded (approximately. 30 seconds)
• The ESP is switched off or on
• The ASR is switched on
• The vehicle is towing a trailer
• The front parking aid is switched on
• The sensor recognize a condition, which would cause damage to the vehicle
• System malfunction
• The driver is responsible for parking the vehicle.
• The parallel parking assistance does not replace the attention of the driver.
• The sensors have dead zones, whereby it cannot recognize people or other objects.
• Pay special attention for small children or animals, because the sensors do not recognize these in every case.
The parallel parking assistance system consists of:
• Parallel Parking Assistance Control Module (J791)
• Left Front Parallel Parking Assistance Sensor (G568) (vehicle - left side)
• Left Front Parking Aid Sensor (G255)
• Left Front Center Parking Aid Sensor (G254)

DTC Recognition and Display
The parallel parking assistance system is equipped with OBD.
Use the Vehicle Diagnosis, Testing and Information System (VAS 5051B) under "Guided Fault Finding".
