the air pressure in the side bolsters of the
seat backrests of the front active multicon-
tour seats is raised.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ® slackens
the belt pre-tensioning. On vehicles with
active multicontour seats, the air pressure in
the side bolsters is reduced again. All settings
made by PRE-SAFE ® can then be reversed.
If the seat belt pre-tensioning is not reduced:

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:
R if the radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
R if 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:
R
if the accelerator pedal is depressed when
a gear is engaged
R if the risk of a collision passes or is no lon-
ger detected
R
if 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:
R the hazard warning lamps are activated
R the emergency lighting is activated
