Emergency brake lights are activated at speeds above 50 km/h(31 mph) if the ABS system is working and/or in the event of heavy braking. After the car's speed has been slowed below 10 km/h(6 mph) the brake light returns from flashing to the normal constant glow - while at the same time the hazard warning flashers are activated, and they flash until the driver accelerates the car to at least 20 km/h(12 mph) or they are deactivated with their button.

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.
