ch nical information about theve hicle's operat‐
ing state, component loads, main tenance
re qu irements and tech nical events or faults.
In general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating status of sy stem components (e.g.
fi ll le vels, battery status, tyre pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, longitudinal accel‐
eration, lateral acceleration, display of fas‐
te ned seat belts)
R malfunctions or faults in impor tant sy stem
components (e.g. lights, brakes)
R information on events leading tovehicle
damage
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
R ambient conditions (e.g. temp erature, rain
sensor) In addition
toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying faults and optimising
ve hicle functions. The majority of this data is
te mp orary and is only processed in theve hicle
itself. Only a small portion of the data is stored
in theeve nt or fault memor y.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty claims and quality assur‐
ance measures, forex ample. The read out is per‐
fo rm ed via the legally prescribed port forthe
diagnostics connection in theve hicle. The
re spective service network locations or third
parties collect, process and use the data. They
document tech nical statuses of theve hicle,
assist in finding faults and impr oving quality and
are transmitted tothe manufacturer, if neces‐
sar y.Fu rthermore, the manufacturer is subject
to product liability. Forth is, the manufacturer
requ irestech nical da tafrom vehicles. Fa
ult memories in theve hicle can be reset by a
service outlet as part of repair or maintenance
wo rk.
Depending on the selected equipment, you can
import data into theve hicle's comfort and info‐
ta inment functions yourself.
This includes, forex ample:
R multimedia data such as music, films or pho‐
to sfo r playback in an integrated multimedia
sy stem
R address book data for use in connection with
an integrated hands-free sy stem or an inte‐
grated navigation sy stem
R entered navigation destinations
R data about the use of Internet services
This data can be sa ved locally in theve hicle or it
is located on a device which you ha veconnected
to theve hicle (e.g. smartphone, USB flash drive
or MP3 pla yer). If this data is stored in theve hi‐
cle, you can dele teit at any time. This data is
sent tothird parties only at your requ est, partic‐
ular lywhen you use online services in accord‐
ance with the settings that you ha veselected. General no

Re
versing the PRE- SAFE®
sy stem measures If an accident did not occur,
the pre-em ptive
measures that we retak en are reve rsed.
Yo u will need toper form certain settings your‐
self. #
Ifth e seat belt pre-tensioning is not reduced,
mo vethe seat backrest back slightl y.
The locking mechanism releases. Fu
nction of PRE-SAFE ®
PLUS (anticipatory
occupant pr otection plus) PRE-
SAFE®
PLUS can de tect cer tain impacts,
particular lyan imminent rear impact, and take
pre-em ptive measures toprotect theve hicle
occupants. These measures cannot necessarily
pr eve nt an imminent impact.
PRE-SAFE ®
PLUS can implement thefo llowing
measures independently of each other:
R Tightening the seat belts on the driver's seat
and front passenger seat.
R Activating there ar hazard warning lights at a
higher flashing frequenc y. R
Increasing brake pressure when theve hicle
is stationar y.This brake application is cancel‐
led automatically when theve hicle pulls
aw ay.
If an accident did not occur, the pre-em ptive
measures that we retake n are reve rsed.
Sy stem limitations
The sy stem will not initiate any action in thefo l‐
lowing situations:
R when reve rsing
or
R when theve hicle is towing a trailer and there
is a risk of a rear impact
The sy stem will not initiate any braking applica‐
tion in thefo llowing situations:
R whilst driving
or
R when entering or exiting a parking space
while using Active Parking Assist Information on PRE-
SAFE®
Impulse Side If an imminent side impact is de
tected, PRE-
SA FE®
Impulse Side can pre-emptively mo vethe
front seat vehicle occupant's upper body
to wa rdsth e cent reoftheve hicle. It does this by
ra pidly inflating an air cushion in the outer seat
side bols ter of the seat backrest on the side on
which the impact is anticipated. This increases
th e dis tance between the door and theve hicle
occupant.
If PRE-SAFE ®
Impulse Side has been deplo yed or
is faulty, thePRE-SAFE impulse side inoperative
