PRE-SAFE®PLUS (anticipatory occu-
pant protection system PLUS)
Introduction
PRE-SAFE®PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE
®
PLUS is able to detect that a head-on or rear-
end collision is imminent. In certain hazard-
ous situations, PRE-SAFE
®PLUS takes pre-
emptive measures to protect the vehicle
occupants.
Important safety notes
The intervention of PRE-SAFE®PLUS cannot
prevent an imminent collision.
The driver is not warned about the interven-
tion of PRE-SAFE
®PLUS.
PRE-SAFE
®PLUS does not intervene if the
vehicle is backing up. PRE-SAFE
®PLUS does not perform braking
actions while the vehicle is in motion or when
Parking Guidance is active.
Function
PRE-SAFE®PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE
®PLUS takes the following meas-
ures depending on the hazardous situation
detected:
Rif the radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
Rif the radar sensor system detects that a
rear-end collision is imminent:
-the brake pressure is increased if the
driver applies the brakes when the vehi-
cle is stationary.
-the seat belts are pre-tensioned.
The PRE-SAFE
®PLUS braking application is
canceled:
Rif the accelerator pedal is depressed when
a gear is engaged
Rif the risk of a collision passes or is no lon-
ger detected
Rif DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting in an accident, the original settings
are restored.
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Occupant safety67
Safety
Z
brake system is still available with complete
brake boosting effect and BAS.
iObserve the restrictions described in the
"Important safety notes" sec-
tion“ (
Ypage 77).
BAS PLUS can help you to minimize the risk of
a collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
PLUS detects a danger of collision, you are
assisted when braking.
Important safety notes
GWARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
BAS PLUS does not react:
Rto small people, e.g. children
Rto animals
Rto oncoming vehicles
Rwhen cornering
As a result, BAS PLUS may not intervene 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
also impaired in the event of:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Rvehicles quickly moving into the radar sen-
sor system detection range
Recognition by the camera system is also
impaired in the event of:
Rdirt on the camera or if the camera is cov-
ered
Rthere is glare on the camera system, e.g.
from the sun being low in the sky
Rdarkness
Rif:
-pedestrians move quickly, e.g. into the
path of the vehicle
-the camera system no longer recognizes
a pedestrian as a person due to special
clothing or other objects
-a pedestrian is concealed by other
objects
-the typical outline of a person is not dis-
tinguishable from the background
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Following damage to the windshield, have the
configuration and operation of the camera
system checked at a qualified specialist work-
shop.
Function
To avoid a collision, BAS PLUS calculates the
brake force necessary if:
Ryou approach an obstacle, and
RBAS PLUS has detected a risk of collision
When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
BAS PLUS is activated. The increase in brake
Driving safety systems77
Safety
Z
pressure will be carried out at the last possi-
ble moment.
When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the traf-
fic situation.
BAS PLUS provides braking assistance in haz-ardous situations with vehicles in front within
a speed range between 4 mph (7 km/h) and
155 mph (250 km/ h).
Up to a speed of approximately 44 mph
(70 km/h), BAS PLUS 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
Robjects crossing your path and that are
recognized in the detection range of the
sensors
iIf BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE
®) are activa-
ted simultaneously.
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, if:
Ryou release the brake pedal.
Rthere is no longer a risk of collision.
Rno obstacle is detected in front of your
vehicle.
Ryou depress the accelerator pedal.
Ryou activate kickdown.
COLLISION PREVENTION ASSIST
PLUS
General information
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous braking function and adaptive
Brake Assist. COLLISION PREVENTION ASSIST PLUS can
help you to minimize the risk of a front-end
collision with a vehicle ahead or reduce the
effects of such a collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you
will be warned visually and acoustically. If you
do not react to the visual and audible collision warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION
PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
Activating or deactivating
COLLISION PREVENTION ASSIST PLUS is
activated after every ignition cycle. You can
activate or deactivate COLLISION PREVEN-
TION ASSIST PLUS in the on-board computer (
Ypage 190). When deactivated, the dis-
tance warning function and the autonomous
braking function are also deactivated.
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æsymbol appears in the
assistance graphics display.
Important safety notes
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Rnew vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system

PRE-SAFE®Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing
upright.
Observe the restrictions described in the
"Important safety notes" sec-
tion“ (
Ypage 85).
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 brak-
ing.
Important safety notes
GWARNING
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.
GWARNING
PRE-SAFE
®Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE
®Brake may:
Rgive an unnecessary warning and then
brake the vehicle
Rnot 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.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.
PRE-SAFE
®Brake can also brake the vehicle
automatically under the following conditions:
Rthe driver and front-passenger have their
seat belts fastened
and
Rthe vehicle speed is between approx-
imately 4 mph (7 km/h) and 124 mph
(200 km/h)
At a speed of up to approximately 44 mph
(70 km/h), PRE-SAFE
®Brake can also detect:
Rstationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
Rpedestrians in the path of your vehicle
GWARNING
PRE-SAFE
®Brake does not react:
Rto small people, e.g. children
Rto animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As a result, PRE-SAFE
®Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
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
also impaired in the event of:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rthere is interference by other radar sources
