The system is protected in such a way that it will only operate in
your vehicle. As as safety measure, the driver must only carry out operations
which require prolonged attention while the vehicle is stationary.
When the engine is switched off and to prevent discharging of
the battery, the system switches off following the activation of
the energy economy mode.
