The emergency brake lights are activated during heavy braking or if the ABS system is activated at high speeds. After emergency braking to a low speed, the brake lights return from flashing to the normal constant glow. The car's hazard warning flashers are activated at the same time. These flash until the driver accelerates the car to a higher speed again or switches off the hazard warning flashers.

Emergency brake lights are activated to alert vehicles behind about heavy braking. The function means that the brake light flashes instead of - as in normal braking - shining with a constant glow.
