Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
On-Board Computer Functions
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.
