Switch-on requesters

The fully automatic switch-on of the engine by MSA can also occur when the driver performs no action at all. Some vehicle conditions (switch-on requesters) require an immediate MSA engine start without action on the part of the driver.

The following switch-on requesters are possible from the perspective of the APM:

• During the MSA stop, the battery charge state falls short of the state of charge required for the MSA function. The engine is switched on again automatically to improve the charge balance.

The current and last four switch-on requesters that occurred are saved in the data of the power management.
