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 168) and hill start assist
(
Y
page 136). For further information, see
"Driving tips" (
Y
page 154).
PRE-SAFE

Observe the "Important safety notes"
section (

page 62).
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 203)
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
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.
At speeds of up to approximately 40 mph
(70 km/h), PRE-SAFE
®
Brake can also detect
stationary objects. Examples of stationary
objects are stopped or parked vehicles.
If you approach an obstacle and PRE-SAFE
®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If the risk of collision with
the vehicle in front remains and you do not
brake, take evasive action or accelerate
significantly, automatic braking may be
performed up to a level of emergency braking.
Automatic emergency braking is not
performed until immediately prior to an
accident that can no longer be avoided.
