Emergency brake lights
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.
The emergency brake lights are activated during
heavy braking or if the ABS system is activated at
high speeds.
After the driver brakes to a low speed and then
releases the brake, the brake light returns to nor-
mal glow.
The car's hazard warning flashers are activated at
the same time. These flash until the driver accel-
erates the car to a higher speed again or
switches off the hazard warning flashers.

Hazard warning flashers
Hazard warning flashers warn other road users
by means of all of the car's direction indicators
being activated simultaneously. The function can
be used to give a warning in the event of traffic
hazards.
Button for hazard warning flashers.
Press the button to activate the hazard warning
flashers.
The hazard warning flashers are automatically
activated when the car brakes so powerfully that
the emergency brake lights are activated and the
speed is low. The hazard warning flashers start to
flash after the emergency brake lights have stop-
ped flashing and are then deactivated automati-
cally when the car drives away again or are deac-
tivated if the button is depressed.
