1

Deactivate easy entry/exit function

Vehicles with memory package (driver seat, steering column, mirrors) code 275

 Otherwise the driver seat and steering wheel move into another position, when the driver door is open or closed. The upper frame will be damaged if the retaining device is installed.

 Deactivation ensues via buttons on the steering wheel in the "Comfort" menu of the multifunction display.

2

Turn steering wheel to central position (front wheels in straight ahead position) and secure with the retaining device

 On a disengaged steering coupling (25) the steering wheel should not be turned because the spiral contact coil will be destroyed.

7

Insert a suitable tool into hole in steering coupling (25) and pull steering shaft (80a) together with locking plate (25f) upward out of steering coupling (25)

 Do not counterhold at the rubber boot or at the plastic temperature protection disk on the bottom side of the steering shaft (80a). Do not use force (hammer blows, strong lever action) because the lower steering shaft (80a) is sensitive to lateral dynamic force and can be damaged.

 Installation: Insert the steering shaft (80a) all the way into the steering coupling (25); when doing so, pay attention to the studs on the steering coupling (25) and the groove in the steering shaft (80a) (arrows).

 The locking plate (25f) is not available as a replacement part.

 Installation: Insert a new self-locking nut in the existing locking plate (25f).
