On approach, OPTIQ automatically greets you with a dazzling lighting sequence. The available illumination starts at the Cadillac Crest on the Black Crystal Shield grille and radiates out, moving vertically in a playful burst. Lights flicker across the turn signals, flow down the headlamps and around all sides, then return to the Crest for a vibrant finale. The effect resembles ‘digital rain.’ 

The lighting sequence occurs in reverse once you reach your destination, park and walk away.
