Shut-off stage for auxiliary heater (shut-off stage 5):
If this shut-off stage is activated the auxiliary heater is subject to the following restriction:

As shut-off stage 5 is only set when shut-off stages 1 and 2 have been passed, all
consumer restrictions entailed by stages 1 and 2 are also active.

Shut-off stage 6 ensures that the control units only remain "awake" briefly below a specific
battery charge level. This function is only activated in response to so-called wake-up events
(such as a door handle being turned) for the CAN/Most bus.

I hope some of you find this information useful..
Thanks
