Manual Operation:The manual adjustments of the seat, mirrors and steering column are
carried out with the respective switches as with the previous systems.
The  mirror  adjustment  switch  is  located  in  the  driver’s  switch  block.  The  mirror  operation
input is a digital signal that is processed by each respective module for mirror positioning.
Memory Storage: The parameters for storing memory positions are are as follows:
• With  the  transmission  range
selector  in  “P”  and  the  mirror
change over switched to the left,
switch  the  ignition  on  and  press
the “M” on the memory switch.
• The memory indicator lamp swi- 
tches on for 7 seconds.
• Press one of the three position 
switches (1, 2 or 3) within the 7  
second memory period.
• The current positions of the mir-
rors, seat and steering column 
are stored for recall.
The positions of the mirrors are stored in the respective door
modules based on the position of the feedback potentiome-
ters. The positions of the seat and steering column are stored
in the seat module, based on the ripple count.
Recalling a memory position setting is possible by either
pressing and holding the recall switch (1, 2 or 3) with KL 15
“ON” or tapping the recall button (1, 2 or 3) with:
• The driver’s door open and KL 15 “OFF”.
