Message come up on display
 

Hi,

Does anyone know why I would get the following message come up.

Convenience functions temporally unavailable, due to battery maintenance.


Followed by another message, Battery/Alternator stop car. ?

Any help would be appreciated on this one

My car is a E280 2005 Model.

Many thanks
Chris

theres 2 batteries in this car.the battery under the pollen filter on left side of car under the bonnet is the one causing the trouble id say.there only the size of a motorbike battery and tend to run dry.
