ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(

( Y page 147). For further information, see
Driving tips ( Y page 161).
PRE-SAFE ® Brake
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
i Observe the "Important safety notes"
section ( Y page 61).
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. If PRE-SAFE
® Brake has detected a
risk of collision, you will be warned visually
and acoustically as well as by automatic
braking. PRE-SAFE
® Brake cannot prevent a
collision without your intervention.
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 will
then sound and the · distance warning
lamp in the instrument cluster will light up.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
At speeds of above approximately
20 mph (30 km/h), if the driver and front
passenger have fastened their seat belts,
PRE-SAFE
® Brake can:
R
brake the vehicle automatically at speeds
up to approximately 124 mph (200 km/h)
R trigger preventative occupant protection
measures (PRE-SAFE
® ) ( Y page 48)
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE
® Brake. To stop the
braking action, you can either depress the
accelerator pedal further, activate kickdown
or release the brake pedal.
The braking action of PRE-SAFE
® Brake is
ended automatically if:
R
your speed drops below approximately
9 mph (15 km/h).
R
you maneuver to avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R
there is no longer an obstacle detected in
front of your vehicle.
