than 50 km/h the brake lamps flash rapidly.
In this way, traffic travelling behind you
is warned in an even more noticeable man-
ner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard
warning lamps are activated automati-
cally. If the brakes are applied again, the
brake lamps light up continuously. The

ically if you travel faster than 10 km/h. You
can also switch off the hazard warning
