EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section (

page 65).
G WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (
Y
page 388) as well as
display messages (
Y
page 355).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
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 306) and hill start assist
(
Y
page 273).
PRE-SAFE ® Brake
i Observe the "Important safety notes"
section (
Y
page 65).
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE
® Brake can help you to minimize
the risk of a 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.
Above a speed of around 4 mph (7 km/h), this
function warns you if you are very quickly
approaching a vehicle in front. An
intermittent warning tone will then sound and
the · distance warning lamp will light up
in the instrument cluster.
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.
If the driver and front passenger have their
seat belt fastened, PRE-SAFE ® Brake can also
brake the vehicle automatically at speeds
from approximately 4 mph (7 km/h) to
approximately 124 mph (200 km/h).
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ® Brake.
You can prevent the intervention of the PRE-
SAFE ® Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal.
The braking action of PRE-SAFE ® Brake is
ended automatically if:
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.
With the help of the radar sensor system,
PRE-SAFE ® Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds of up to 40 mph (70 km/h), PRE-
SAFE ® Brake can also detect stationary
obstacles, for example, stopped or parked
vehicles.
If you approach an obstacle and PRE-SAFE
®
Brake detects a risk of collision, the system
will initially alert you both visually and
acoustically. If you do not brake or take
