2 for several seconds.
T
he emergency call is now initiated and
a voice connection is established to the
public emergency call centre.
If you have accidentally pressed the emer-
gency call button, cancel the emergency
call immediately:
1. Press the emergency call button again
until the indicator lamp lights up green
continuously.
Automatic emergency call
An automatic emergency call is initiated
only when the ignition is switched on.
A connection to the emergency call centre
is set up immediately aer the airbags or
belt tensioners have been triggered. You
cannot cancel the automatic emergency
call by pressing the emergency call button
.
R
escue measures will be initiated automat-
ically if there is no response to questions
from the public emergency call centre.
Integrated battery
The integrated battery ensures that the le-
gally required eCall Emergency System re-
mains available for some time if the 12-volt
vehicle battery is disconnected or faulty.
A corresponding message will be displayed
in the instrument cluster display if the inte-
grated battery is discharged or faulty
→ page 76, Troubleshooting. If the corre-
sponding message is displayed, go to
a qualified workshop immediately and have
the integrated battery replaced.
Data transmission
In the event of an emergency call, the le-
gally prescribed data is transmitted to the
public emergency call centre in order to de-
termine necessary rescue measures.
The data on the vehicle location is continu-
ously overwritten so that only the last three
stored locations required for correct func-
tioning of the legally required eCall Emer-
gency System are available. The vehicle is
therefore not permanently tra
cked.
The data relating to the emergency call is
processed exclusively in order to ensure
correct functioning of the legally required
eCall Emergency System. The data relating
to the emergency call will be deleted auto-
matically by the system 13 hours aer the
emergency call was initiated.
The transmitted data includes the follow-
ing:
— Current position of the vehicle when the
emergency call was initiated.
— Two other positions, a few 100
m (around 328 ) of the driving route,
shortly before the emergency call was in-
itiated.
— Vehicle identification number (VIN).
— Type of vehicle drive.
— Vehicle class.
— Type of initiation (automatic or manual).
— Type of call.
— Direction in which the vehicle was mov-
ing when the emergency call was trig-
gered.
— Time of the collision.
— Reliability of the positioning data.
— Data record version.
— Counter for transmitted data records per
call.
— Estimated number of passengers per
call.
Troubleshooting
eCall Emergency System fault
The indicator lamp in the emergency call
button lights up red c
ontinuously
. In addi-
tion, a messa
ge may be displayed in the in-
strument cluster.
There is a system fault in the eCall Emer-
gency System. It is not possible to make an
emergency call.
1. Go to a suitably qualified workshop im-
mediately and have the fault rectified.
