Battery/Alternator
Stop vehicle
The battery is malfunctioning.
The electrohydraulic brake system re-
quires electrical energy and therefore has
only limited operation. Considerably
greater brake pedal force is required and
the stopping distance is increased.
̈ Stop the vehicle in a safe location as
soon as it is safe to do so. Adjust driv-
ing to be consistent with reduced
braking responsiveness.
̈ Notify an authorized Mercedes-Benz
Center.

The battery has insufficient voltage. ̈ Start the engine (୴ page 50).
Malfunction
Electrical consumers
switched off
The consumer battery has insufficient
voltage and can no longer supply the con-
venience functions such as seat ventila-
tion*.

online as soon as on-board voltage is suf-
ficient.
