Active Brake Assist with cross-traffic
function
General information
Active Brake Assist with cross-traffic functioncan help you to minimize the risk of a collisionwith the vehicle in front or a pedestrian. ActiveBrake Assist with cross-traffic function canalso reduce the effects of such a collision. IfActive Brake Assist with cross-traffic functionhas detected a risk of collision, you will bewarned visually and acoustically as well as byautomatic braking.
iPay attention to the important safety notesin the "Driving safety systems" section(Ypage 60).
Active Brake Assist with cross-traffic functionis only available in vehicles with the DrivingAssistance Plus package.
For Active Brake Assist with cross-traffic func-tion to assist you when driving, the radar sen-sor system and the camera system must beoperational.
The radar sensor system and camera systemhelp Active Brake Assist with cross-trafficfunction to detect obstacles that are in thepath of your vehicle for an extended period oftime.
In addition, pedestrians in the path of yourvehicle can be detected.
Active Brake Assist with cross-traffic functiondetects pedestrians using typical characteris-
tics such as body contours and the posture ofa person standing upright.

Important safety notes
GWARNING
Active Brake Assist with cross-traffic func-
tion will initially brake your vehicle by a par-
tial application of the brakes if a danger of
collision is detected. There may be a colli-
sion unless you brake yourself. Even after
subsequent full application of the brakes a
collision cannot always be avoided, particu-
larly 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.
If you partially apply the brakes, the vehicle isbraked with up to 50% of the full braking force.
GWARNING
Active Brake Assist with cross-traffic func-
tion cannot always clearly identify objects
and complex traffic situations.
In such cases, Active Brake Assist with
cross-traffic function might:
Rgive an unnecessary warning and then
brake the vehicle
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, espe-
cially if Active Brake Assist with cross-traffic
function alerts you. Terminate the interven-
tion in a non-critical driving situation.
GWARNING
Active Brake Assist with cross-traffic func-
tion cannot always clearly identify people,
particularly 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, espe-
cially if Active Brake Assist with cross-traffic
function alerts you.
In order to maintain the appropriate distanceto the vehicle in front and thus prevent a colli-sion, you must apply the brakes yourself.
GWARNING
Active Brake Assist with cross-traffic func-
tion 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
accident.
Always pay careful attention to the traffic
situation 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 differentline
Recognition by the camera system is alsoimpaired in the event of:
Rdirt on the camera or if the camera is cov-ered
Rglare on the camera system, e.g. from thesun being low in the sky
Rdarkness
Ror if:
-pedestrians move quickly, e.g. into thepath of the vehicle
-the camera system no longer recognizes apedestrian as a person due to specialclothing or other objects
-a pedestrian is concealed by otherobjects
-the typical outline of a pedestrian is notdistinguishable from the background
Following damage to the front end of the vehi-cle, have the configuration and operation ofthe radar sensors checked at a qualified spe-cialist workshop. This also applies to collisionsat slow speeds where there is no visible dam-age to the front of the vehicle.
Following damage to the windshield, have theconfiguration and operation of the camera sys-tem checked at a qualified specialist work-shop.

Up to a speed of approximately 44 mph(70 km/h), Active Brake Assist with cross-traf-fic function may react to:
Rstationary objects in the path of your vehi-cle, e.g. stopped or parked vehicles
Rpedestrians in the path of your vehicle
iIf there is an increased risk of a collision,preventive passenger protection measures
(PRE-SAFE®) are triggered (Ypage 55).
If the risk of collision with the vehicle in frontremains and you do not brake, take evasiveaction or accelerate significantly, the vehiclemay perform automatic emergency braking, upto the point of full brake application. Auto-matic emergency braking is not performeduntil immediately prior to an imminent acci-dent.
You can prevent the intervention of ActiveBrake Assist with cross-traffic function at anytime by:
Rdepressing the accelerator pedal further
Ractivating kickdown
Rreleasing the brake pedal
The braking application of Active Brake Assistwith cross-traffic function is ended automati-cally if:
Ryou maneuver to avoid the obstacle
Rthere is no longer a risk of collision
Ran obstacle is no longer detected in front ofyour vehicle
