Electric consumers
offline!
The consumer battery has insuffi-
cient voltage and can no longer sup-
ply the convenience functions such
as seat ventilation*.
The electrical consumers will come back online
as soon as on-board voltage is sufficient.
Battery/Alternator
Stop vehicle!
The battery was charged with a bat-
tery charger or jump started.
The battery is no longer charging.
Possible causes
alternator malfunctioning
broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may
be operating with restricted capabil-
ity. Considerably greater brake ped-
al force is required and the stopping
distance is increased.
Have the battery checked at a service sta-
tion.
Stop immediately and check the poly-V-belt.
If it is broken
Do not continue to drive. Notify an autho-
rized Mercedes-Benz Center.
If it is in order
Drive immediately to the nearest autho-
rized Mercedes-Benz Center. Adjust driv-
ing to be consistent with reduced braking
responsiveness.
