this data is used tooptimise
communication between theve hicle and the
mobile phone.
To do this, and toassign se veralve hicles tothe
mobile phone, a vehicle identifier is randomly
ge nerated.
This has no connection totheve hicle identifica‐
tion number (VIN) and is dele ted when the multi‐
media sy stem is reset (/ page 266).
The following driving status data is transmitted:
R Transmission position engaged
R Distinction between par ked, standstill, rolling
and driving
R Day/night mode of the instrument clus ter
