To summon help in case of illness, external threats to the car or passengers, an emergency call centre can be alerted manually by depressing the SOS button for at least 2 seconds. The emergency call centre is notified and told of the car's position1, etc., and attempts to establish verbal contact with the driver in order to agree what assistance is needed.
Note
The SOS button is only designed for emergencies and must only be used in the event of an accident, illness or an external threat to the car and its passengers. The ON CALL button must be used in the event of problems with the car.
