still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and

PRE-SAFE ® Brake (vehicles with
DISTRONIC PLUS)
PRE-SAFE ® Brake can help you to minimize
the risk of a frontal collision with a vehicle
ahead or reduce the effects of such a
collision.
At speeds above approximately
20 mph (30 km/h), this function warns you
when you are rapidly approaching the vehicle
in front. An intermittent warning tone sounds
and the · distance warning lamp lights up
in the instrument cluster.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
If the driver and front-passenger have
fastened their seat belts, PRE-SAFE
® Brake
can also can also perform the following at
speeds of above approximately
20 mph (30 km/h):
R brake the vehicle automatically at speeds
up to approximately 124 mph (200 km/h)
R
trigger preventative passenger protection
measures (PRE-SAFE
® ) ( Y page 53)
G Warning!
An intermittent warning sounds and the
distance warning lamp · in the instrument
cluster is illuminated if the PRE-SAFE
® Brake
calculates that the distance to the vehicle
ahead and your vehicle's current speed
indicate that the PRE-SAFE
® Brake will not be
capable of slowing the vehicle sufficiently to
maintain the preset following distance, which
creates a danger of a collision.
