On-Board Computer Functions
WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.
There are two ways in which on-board computer functions can be displayed:
- in the instrument cluster
- in the Central Information Display (extended on-board computer functions)
The on-board computer functions for the instrument cluster are as follows:
- Ambient temperature
- Time
- Date
- Average consumption (resettable)
- Range
- Average speed (resettable)
The on-board computer function required can be displayed: When terminal R is ON by pressing the on-board computer button on the turn-signal/main-beam switch in a specific sequence. The last line is followed by an empty line, before the first line reappears on the screen (rolling list). When terminal R switches ON, the on-board computer function most recently selected by means of the on-board computer button reappears. If the on-board computer button is pressed and held down for longer than 2 seconds, the values of the resettable on-board computer functions are recalculated.
