The SBC brake system requires elec-
trical energy and therefore has only
limited operation. Considerably
greater brake pedal force is required
and the stopping distance is in-
creased.

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.

Failure to follow these instructions can re-
sult in severe injury or death.
Never lean over batteries while connecting,
you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek

A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the key is in the starter switch. Oth-

nance intervals or contact your autho-
rized Mercedes-Benz Center for further
information.Warning!

this could result in a short circuit.
Use leak-proof batteries only to avoid the
risk of acid burns in the event of an acci-
dent.
