3 Series E91 330d (M57T2) TOUR
In vehicles equipped with BMW Assist, the multiple restraint system (MRS) has an additional function: the
automatic emergency call.
In the event of an accident exceeding a certain level of severity, BMW Assist automatically initiates an
emergency call. The vehicle data and its exact location, which is determined by the navigation system, are
transmitted to the emergency call centre.
Emergency call (US version)
•
Manual emergency call
A manual emergency call is initiated by the emergency call button. The emergency call button is directly
connected to the telephone. Pressing the emergency call button establishes a voice connection with the
provider. The emergency call button is integrated into the roof control panel (FZD).
•
Automatic emergency call:
If the accident is of corresponding severity, the MRS control unit sends a signal to the Telematics Control
Unit (TCU). The TCU initiates an emergency call which also contains the location of the vehicle. The TCU
receives the location determination for the navigation system. If a navigation system has not been installed,
the location is determined by an internal GPS receiver in the TCU.
