General ly,th e use of these data is temp orar y;
th ey will not be stored be yond the period of
operation and will only be processed within the
ve hicle itself. Control units of ten contain da ta
memories forve hicle keys,fo rex ample. Their
use permits thete mp orary or permanent docu‐
mentation of tech nical information about the
ve hicle's operating state, component loads,
main tenance requ irements and tech nical events
or faults.
Depending on theve hicle equipment, thefo llow‐
ing data are stored:
R operating status of sy stem components,
such as fill le vels, tyre pressure or battery
st atus
R malfunctions or faults in impor tant sy stem
components, such as lights or brakes
R system reactions in special driving situations,
such as airbag deployment or the inter ven‐

In cer tain cases, it may be requiredtostore data

de tected a malfunction, forex ample.
If yo u use services, such as repair services and
maintenance work,st ored operational data as
we ll as theve hicle identification number can be
re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manufacturers or third parties, such as
breakdown services. The same is true in the
case of warranty claims and quality assurance
measures.
In general, there adout is per form ed via the
legally prescribed port forth e diagnostics con‐
nection in theve hicle. The operational data that
are read out document tech nical states of the
ve hicle or of individual components and assist in
th e diagnosis of malfunctions, compliance with
wa rranty obligations and quality impr ovement.
To that end, these data, in particular information
about component loads, tech nical events, mal‐ functions and
other faults may be transmitted
along with theve hicle identification number to
th e manufacturer. Furthermore, the manufac‐
turer is subject toproduct liability. Forth is rea‐
son the manufacturer also uses operational data
from theve hicle, forex ample, forre calls. These
da ta can also be used toexamine the cus tom‐

Fa ult memories in theve hicle can be reset by a
service outlet or at your requ est as part of repair
or maintenance work.

tomatic measures af ter an accident
Depending on the type and se verity of the acci‐
dent, and depending on theve hicle's equipment,
th efo llowing measures can be implemen ted, for
ex ample:
R automatic braking (post-collision brake)
R activating the hazard warning lights
R triggering an automatic emer gency call
(/ page 334)
R switching off the engine
To restart theve hicle, switch the ignition off
and switch it back on (/ page189).
Depending on the type and se verity of the
accident, it is possible that theve hicle can
no longer be star ted. R
switching off the fuel supply
R unlocking theve hicle doors
R lowe ring the side windo ws
R displaying the emer gency guide in the cent ral
display
R switching on the interior lighting
Fu nction of the post-collision brake
Depending on the accident situation, the post-
collision brake can minimise the se verity of a fur‐
th er collision or evenavo id it.
If an accident is de tected, the post-collision
brake can implement automatic braking. When
th eve hicle has come toast andstill, the electric
parking brake is automatically applied.
The driver can cancel automatic braking bytak‐
ing thefo llowing actions:
R braking more stronglythan automatic brak‐
ing
R fully depressing the accelerator pedal with
