Be prepared to brake or swerve if neces-
sary.
If Active Brake Assist is deactivated or the func-
tions are restricted, e.g. due to activation of
another driving system, the ê Active Brake
Assist warning lamp will appear on the driver's
display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a fault, or if the functions
are restricted, the Ó Active Brake Assist warn-
ing lamp will appear on the driver's display.
Also observe the system limits of Active Brake
Assist.
The individual subfunctions are available in the fol-
lowing speed ranges:
Collision warning
Collision warning can assist you in the following
situations from approximately 4 mph (7 km/h)
with an intermittent warning tone and the L
distance warning lamp.
Vehicles with PRE-SAFE
®
: depending on the coun-
try, an additional haptic warning will occur in the
form of slight, repeated tensioning of the seat
belt.
