The brightness of the graphics is automatically adapted to their background light conditions. The brightness is also affected by the adjustment of the brightness in the car's other displays.
The vertical position can be stored in the memory function of the power front seat*.
Calibrate the horizontal position
The head-up display's horizontal position may need to be calibrated if the windscreen or display unit is replaced. Calibration means that the projected image is rotated clockwise or anticlockwise.

Cleaning
Gently wipe the display's cover glass with a clean and dry microfibre cloth. If necessary, lightly moisten the microfibre cloth.
Never use strong stain removers. A special cleaning agent available from Volvo dealers can be used for more difficult cleaning.
When replacing the windscreen
Cars with head-up display are equipped with a special type of windscreen that meets the requirements for displaying the projected image.
When replacing the windscreen - contact an authorised workshop1. The correct version of the windscreen must be fitted in order that the head-up display's graphics shall be displayed correctly.
