EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressureon the rear wheels to improve driving stabilitywhile braking.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 65).
GWARNING
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 andwarning lamps (Ypage 259) as well as displaymessages (Ypage 230).

Active Brake Assist with cross-traffic
function
General information
iObserve the important safety notes in the"Driving safety systems" section (Ypage 65).
Active Brake Assist with cross-traffic functioncan help you to minimize the risk of a collisionwith a vehicle in front or a pedestrian and reducethe effects of such a collision. If the Active BrakeAssist with cross-traffic function detects a riskof collision, you will be warned visually andacoustically and, if necessary, your brake appli-cation will be assisted according to the situa-tion. If you do not react, the system can alsoreact by braking automatically. In the event of adetected risk of collision due to crossing traffic,you will also be visually and acoustically warnedas well as assisted by the brake boosting effectaccording to the situation.
Active Brake Assist with cross-traffic function isonly available in vehicles with the Driving Assis-tance Plus package.
For Active Brake Assist with cross-traffic func-tion to assist you when driving, the radar sensorsystem and the camera system must be opera-tional.
If the radar sensor system or the camera systemis malfunctioning, Active Brake Assist withcross-traffic function is restricted or no longeravailable. The brake system is still available withcomplete brake boosting effect and BAS.
The radar sensor system and camera systemhelp Active Brake Assist with cross-traffic func-tion to detect obstacles that are in the path ofyour vehicle for an extended period of time.
In addition, pedestrians in the path of your vehi-cle can be detected.
Active Brake Assist with cross-traffic functiondetects pedestrians using typical characteris-tics such as body contours and the posture of aperson standing upright.
iObserve the restrictions described in the"Important safety notes" section(Ypage 72).
Important safety notes
GWARNING
Active Brake Assist with cross-traffic function
will initially brake your vehicle by a partial

Safety

application of the brakes if a danger of colli-
sion is detected. There may be a collision
unless you brake yourself. Even after subse-
quent full application of the brakes a collision
cannot always be avoided, particularly 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 fullbraking pressure.
GWARNING
Active Brake Assist with cross-traffic function
cannot always clearly identify objects and
complex traffic situations.
In such cases, Active Brake Assist with cross-
traffic function might:
Rissue an unnecessary warning or engage
Rneither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially
if Active Brake Assist with cross-traffic func-
tion alerts you. Terminate the intervention in a
non-critical driving situation.
GWARNING
Active Brake Assist with cross-traffic function
cannot always clearly identify people, partic-
ularly if they are moving. Active Brake Assist
with cross-traffic function cannot intervene in
these cases. There is a risk of an accident.
Always pay particular attention to the traffic
situation and be prepared to brake, especially
if Active Brake Assist with cross-traffic func-
tion alerts you.
In order to maintain the appropriate distance tothe vehicle in front and thus prevent a collision,you must apply the brakes yourself.
GWARNING
Active Brake Assist with cross-traffic function
does not react:
Rto small people, e.g. children
Rto animals
Rto oncoming vehicles
Rwhen cornering
As a result, Active Brake Assist with cross-
traffic function may not warn you or engage in
all critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-ognition can be impaired.
Recognition by the radar sensor system is alsoimpaired if:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-ple in parking garages
Ra narrow vehicle is traveling in front, e.g. amotorbike
Ra vehicle is traveling in front on a different line
Rvehicles moving quickly into the radar sensorsystem detection range
Recognition by the camera system is alsoimpaired in the event of:
Rdirt on the camera or if the camera is covered
Rglare on the camera system, e.g. from the sunbeing low in the sky
Rdarkness
Ror if:
-pedestrians move quickly, e.g. into the pathof the vehicle
-the camera system no longer recognizes apedestrian as a person due to special cloth-ing or other objects
-a pedestrian is concealed by other objects
-the typical outline of a pedestrian is notdistinguishable from the background
Following damage to the front end of the vehicle,have the configuration and operation of theradar sensors checked at a qualified specialistworkshop. This also applies to collisions at slow
