How to Turn On the S90 Ambient Lighting?
2 Answers
The ambient lighting button is located on the central LCD display. Press the vehicle's one-touch start button to power on the vehicle; otherwise, you cannot adjust the ambient lighting. Click the screen touch button on the right side of the steering wheel to activate the ambient lighting adjustment function on the central LCD display. You will see the vehicle's ambient lighting display different colors based on the adjustments made on the central screen. Choose your preferred color.
Just helped a friend adjust the ambient lighting in his S90 a couple of days ago. Found the little car icon below the center console screen, tap into it, then select 'Settings' → 'My Car' → 'Lighting'. There's an ambient lighting option inside - tap to switch between seven colors, plus there's a brightness slider. The brightness setting before engine-off gets remembered automatically, but the color needs to be reselected each startup. If the settings malfunction, it's probably system lag - locking the car after turning off and waiting ten minutes usually fixes it. Remember not to install metalized window films as they interfere with signals - dealership says this causes touchscreen glitches.
