Emergency function

The GEM is equipped with restricted emergency running functions on vehicles with mid or high-end equipment levels.

The microcontroller sends a control signal to a monitoring function within the GEM at regular intervals. If the battery voltage falls below a value of approx. 7.5 volts, this check signal is not present and the GEM switches to emergency function after a predetermined time.

In this case, the low beam is permanently switched on, regardless of the light switch position. The windshield wiper can only be operated in stage 1; the wiper switch must however be in the stage I or II position. The wiper park position is not recognized. Intermittent wiping is not available.

When the control signal recurs, the GEM switches back to normal operation.
