Geo fencing Geo fencing allows you to select areas which the
vehicle should not enter or leave. You will be
informed if the vehicle crosses the boundaries
of the selected areas. You can select the way in
which you receive this information beforehand.
Possible options include text message, e-mail or
an automated call.
The area can be determined as either a circle or
a polygon with a maximum of ten corners. You
can specify up to ten areas simultaneously. Dif-
ferent settings are possible for each area.
These settings can be called up under "Owners
Online" at http://www.mbusa.com.
Alternatively, you can trigger an MB Info call and
inform the customer service representative that
you wish to activate geo fencing.
Currently inactive areas can be activated by text
message.
Triggering the vehicle alarm With this function, you can trigger the vehicle's
panic alarm via text message. An alarm sounds
and the exterior lighting flashes. Depending on
the setting, the panic alarm lasts five or ten sec-
onds. Afterwards, the alarm switches off.
