Function 

The limp-home function ensures that the steering column can be adjusted to the driving position  even if a fault occurs with the position measurement  so that the driver's airbag continues to function properly when the vehicle is in use.

In the limp-home mode, the steering column can be adjusted manually using the steering column adjustment raise/lower, forward/back switch (S59/1s1)  but only for a period of t = 2 seconds  .

The switch must be released and pressed again after each actuation.

The steering column cannot be adjusted using the easy entry/exit  or memory (seat adjustment/mirror adjustment/steering column adjustment)  functions in the limp-home mode.

The failure of the hall signals for the motors (steering column adjustment) is displayed in the instrument cluster (A1)  .
