EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes

Observe the "Important safety notes" sec-
tion (

WARNING
If EBD is malfunctioning, the rear wheels can
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 spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Y
page 258) as well as display
messages (
Y
page 227).
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 172) and hill start
assist (
Y
page 139).

Brake
General information
PRE-SAFE
®
Brake can help you to minimize the
risk of a collision with a vehicle ahead or a
pedestrian, and 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.
i
Pay attention to the important safety notes
in the "Driving safety systems" section
(
Y
page 65).
PRE
‑
SAFE
®
Brake is only available in vehicles
with the Driving Assistance Plus package.
For PRE-SAFE
®
Brake to assist you when driving,
the radar sensor system and the camera system
must be switched on and be operational.
With the help of the radar sensor system and the
camera system, PRE-SAFE
®
Brake can detect
obstacles that are in front of your vehicle for an
extended period of time.
In addition, pedestrians in the path of your vehi-
cle can be detected.
PRE-SAFE
®
Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing upright.
i
Observe the restrictions described in the
"Important safety notes" sec-
tion“ (
Y
page 72).

WARNING
PRE-SAFE
®
Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-
ularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
In the event of a partial application of the brakes,
the vehicle is braked with up to 50% of the full
braking pressure.
G
WARNING
PRE-SAFE
®
Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE
®
Brake may:
R
give an unnecessary warning and then
brake the vehicle
R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE
®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
