R
Always pay careful attention to the traf‐
#
fic situation; do not rely on Active Brake
Assist alone. Active Brake Assist is only
an aid. The driver is responsible for
maintaining a suitable distance to the
vehicle in front, vehicle speed and for
braking in good time.
Be prepared to brake or swerve if nec‐
#
essary.
Observe the system limitations of Active Brake
Assist.
The individual subfunctions are available in
the following speed ranges:
Distance warning function
The distance warning function issues a warning
at speeds:
From approximately 30 km/h, if over several
R
seconds the distance maintained to the vehi‐
cle travelling in front is insufficient for the
driven speed. The L distance warning
lamp then lights up in the instrument cluster.
From approximately 7 km/h, if your vehicle
R
is critically close to a vehicle or pedestrian.
An intermittent warning tone sounds and the
L distance warning lamp lights up in the
instrument cluster.
Brake immediately or take evasive action, provi‐
ded it is safe to do so and the traffic situation
allows this.
