Steering Column Adjustment
The E65 is supplied with electrical steering column adjustment.
The adjuster knob for the adjustment is located on the left-hand side of the steering column trim.
The electrical steering column adjustment incorporates the comfort entry function. The steering wheel can be adjusted fore and aft and vertically to suit the driving position.
The steering wheel position is a car memory function and is memorized together with the driver's seat position and stored in the Seat Module (SMFA).
When the ignition is switched off and the door opened, the steering wheel is moved to its highest and most forward position to make getting in and out of the car easier.
The adjuster button has four possible directions of movement. These enable the steering wheel to be moved up, down, forwards or backwards.
The signal from the adjustment knob is from the SZL to the SIM to the ZGM via the byteflight. The signal then is placed on the K-CAN-S by the ZGM and received by the CIM.
Control of the electric motors for steering column adjustment is carried out by the Chassis Integration Module (CIM)
