Switch-on response

The head-up display is partially operational when terminal R is switched ON. This means:

• The projection display is initialised but information is not yet displayed.
• The head-up display is able to communicate with other bus-elements via the MOST and K-CAN data buses.

The head-up display is operational when terminal 15 is switched ON. This means:

• The light source is switched on when the button for switching the head-up display on and off is pressed.
• The projection display cover panel is folded out of the beam by the stepper motor.
  • E70

  The E70 has no cover panel for the projection display. One mirror is swivelled away to protect the display against direct sunlight when parked. As from terminal 15 ON the mirror is swivelled from the park position into the position stored by the Car and Key Memory.

• The automatic adaptation of the display brightness is activated.
• E70

  The image orientation of the virtual image can be height-adjusted.
