Trailer stabilization is active above speeds of
about 37 mph (60 km/h).
Trailer stabilization does not work if ESP

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 319) as well as
display messages ( Y page 285).
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 207) and hill start assist
( Y page 161).
PRE-SAFE ® Brake
i Observe the "Important safety notes"
section ( Y page 66).
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
If PRE-SAFE ® Brake is to aid you, the radar
sensor system must be:
R
activated ( Y page 277)
R
operational
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.
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.
Starting at a speed of around
4 mph (7 km/h), this function warns you if
you very quickly approach 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.
From a speed of approximately
4 mph (7 km/h), if the driver and front
passenger have fastened their seat belts,
PRE-SAFE
® Brake can brake the vehicle
automatically at speeds up 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
