Brake Lamp: Description and Operation



Lighting System

Adaptive brake lights







The adaptive brake lights of the Cayenne models produce a pulsating luminous intensity during emergency ABS braking or in the event of extreme deceleration from a speed of more than 45 mph (70 km/h) in order to more effectively alert vehicles travelling behind. If this extreme deceleration brings the vehicle to a standstill, the hazard warning lights come on automatically.
