The system is intended for emergency situations when the driver is sud-

denly unable to take over the steering task. Therefore, never try to test out
the system - there is a risk of an accident!
Function

on page 260 first.
The assistant for emergencies (following known as system) detects inactivity
of the driver, which for example can be caused by a sudden loss of conscious-
ness. The system then performs measures as safely as possible to decelerate
the vehicle to a stop.
The system is only available for vehicles with Automatic transmission.

System intervention
If the system detects the driver's inactivity, it draws attention to this fact by a
beep and a message on the display of the instrument cluster. It keeps the vehi-
cle in its lane.
If the driver does not take over the steering even after a repeated warning, the
system automatically brakes the vehicle and after it has come to a standstill
the parking brake switch on.
With automatic braking, the hazard warning system is switched on.
The automatic braking interventions can be cancelled by pressing the acceler-
ator pedal or by means of a steering intervention.
