Prerequisites for Trailer Assist
Calibrating the trailer
To re-determine the drawbar length, the trailer must be calibrated with each change to the combination of vehicle
and trailer.
There are a maximum of four limits on the angle display: Approximately 30°, 45°, 60° and 75°.
The more accurately the system is able to calculate the drawbar, the more angles are available when maneuvering.
1. Attach the one or two-axle trailer and electrically connect with the vehicle.
2. Perform multiple, ideally different, turning and cornering maneuvers with the trailer.
Requirements
✓ The trailer with non-steering axles is properly connected.
✓ The drawbar must not be covered.
✓ The vehicle and trailer are stationary.
✓ The driver door and trunk lid are closed.
✓ The maximum trailer angle is not exceeded.
✓ The outside mirrors must not be folded in.
✓ ESC
is switched on.
✓ A driver interaction must occur within around three minutes, otherwise the maneuvering process will be
interrupted and Trailer Assist is deactivated.
