Rev counter. Night driving button. Instrument unit brightness
The rev counter in the Citroën C6 helps not only with sporty driving but also with fuel-efficient driving. This chapter shows when a gear change is advisable and how to avoid running the engine at excessively high revs. The information is supplemented by the "Night driving" function, which activates a reduced display, ideal for relaxed journeys in the dark. In addition, the brightness of the instrument cluster can be adjusted to suit individual visual comfort. In this way, the Citroën C6 combines driving enjoyment, clear presentation and modern operation, day and night.
Tachometer
When approaching maximum engine speed, a transition into the red zone indicates that the next higher gear should be engaged.



Night driving control
- The first press of the DARK control puts the display into standby mode. Only the time and date remain displayed.
- A second press switches off the display and the instrument cluster, except for the following information:
- Speedometer.
- Automatic transmission.
- Speed limiter/cruise control, if activated.
Instrument cluster brightness

With the lighting switched on, press controls C or D to change the brightness of the instrument cluster lighting.
In the "Main menu", the "Configuration" menu allows the display brightness to be adjusted. See "Display" and the NaviDrive chapter.
For better visibility, the angle of the NaviDrive display can also be adjusted by pressing controls A and B.
The rev counter and the night driving control of the Citroën C6 provide additional comfort and safety. The rev counter gives precise information about engine output, while the night driving control reduces the displays to allow glare-free vision. Both systems contribute to a more relaxed and safer driving experience.
The ability to adjust the brightness of the instrument cluster also shows the high standard of individual settings offered by the Citroën C6. Every journey is thus optimally matched to the lighting conditions, which noticeably increases comfort.
The Citroën C6 offers a perfect combination of functionality and driving comfort, ideal for anyone who values optimal visibility and control, even on long journeys.
