Button illumination and lighting for controls
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
DICE supplies power to the button illumination and lighting for the controls. To enable adjustment of the brightness, DICE pulse width modulates (PWM) the power supply to the bulbs.
If Night Panel on the SID has been selected, the bulbs for button illumination and lighting for the controls will shine at reduced strength.
