Head-Up Display

The Head-Up Display in the Citroën C6 (I Gen) projects important information directly into the driver's field of view, from speed and navigation prompts to warning symbols. This chapter describes in detail how the system is switched on and off, adjusted for height and brightness, and personalised. Besides convenient use, it also covers storing personal settings for different drivers. Technical notes and recommendations ensure optimal legibility, even in difficult lighting conditions or with certain eyeglasses. A prime example of innovative technology in the upper-class segment.

The head-up display system projects a range of important information into the driver's field of view. This way, the driver does not need to take their eyes off the road.

The head-up display controls are located below the ventilation outlet on the driver's side.

Activation/deactivation

To activate/deactivate the Head-Up Display: after switching on the ignition, press control 1.

The on/off state set when the engine is switched off is retained when restarting.

Height adjustment

To adjust the height of the Head-Up Display, press controls 2 and 3.

It is recommended to set the display height as low as possible.

Brightness adjustment

The Head-Up Display system has a brightness sensor that ensures optimal visibility of the information regardless of ambient brightness.

In addition, the display brightness can be adjusted by turning control 1.

Note:

• In certain extreme weather conditions (rain and/or snow, strong sunlight), the Head-Up Display may be temporarily disturbed or unreadable.
• After leaving a tunnel, the system needs a short moment to adjust the display brightness to the ambient brightness.

Note: With some eyeglasses, the Head-Up Display may be difficult to read.

Storing the driver's seat and Head-Up Display positions

The Head-Up Display settings are taken into account when the driving position is stored (see "Memory") and concern:

• Display height.
• Brightness.
• Information selection.

If the Head-Up Display is not readable, it is recommended to check the height settings (controls 2 and 3) and the activation (control 1).
