Seat calibration function - GF91.29-P-3005PP

MODELS 203.0 /2 /7 with CODE (275c) Electrically adjustable driver seat, steering column and exterior mirrors with memory with CODE (242b) Electrically adjustable front passenger seat with memory 

Normalizing 

Normalizing is important for the assignment between the absolute adjustment position and the position recorded by the driver-side front seat adjustment control unit with memory (N32/1) and the passenger side front seat adjustment control unit with memory (N32/2).

Normalization must be performed during initial start-up or in a denormalized condition.

The following seat stops have to be moved to for the normalization procedure:

• Seat longitudinal adjustment: front stop position
• Seat angle adjustment: lower stop position
• Seat height adjustment: lower stop position
• Seat backrest adjustment: front stop position
• Seat head restraint adjustment upper stop

Operating procedure 

Operate the seat fore/aft switch (S91/2s1 and S92/2s1), the rear seat raise/lower switch (S91/2s2 and S92/2s2), the front seat raise/lower switch (S91/2s3 and S92/2s3), the head restraint raise/lower switch (S91/2s4 and S92/2s4) and the backrest switch (S91/2s5 and S92/2s5) in the left front door seat adjustment switch group (Memory) (S91/2) and the right front door seat adjustment switch group (Memory) (S92/2), until the mechanical stop has been reached and hold down for an additional 0.25 seconds.

Renormalization 

Renormalization takes place if one of the two above-mentioned stop positions is moved to in a normalized state.

Denormalization 

Denormalization takes place:

• the battery is disconnected (G1) or
• the mechanical stop is exceeded.
