Battery/
Alternator
Stop vehicle
The battery or the alternator is
malfunctioning.
The electrohydraulic brake sys-
tem requires electrical energy
and therefore has only limited
operation. Considerably great-
er brake pedal force is required
and the pedal travel is longer.
The stopping distance is in-
creased.

Stop the vehicle as soon as it is safe to do so. Adjust driv-
ing to be consistent with reduced braking responsive-
ness.

Notify an authorized Mercedes-Benz Center immediate-
ly.

Read and observe messages in the multifunction display.
Failure to follow these instructions increases the risk of an
accident.
Convenience func-

Unavailable
The consumer battery has in-
sufficient voltage and can no

functions such as power win-
dows.
The electrical consumers will come back online as soon as
on-board voltage is sufficient.

Brake wear
Visit
workshop
The brake pads have reached
their wear limit.

Have the brake pads replaced immediately.
!Brake pad thickness must be visually
checked by a qualified technician at the
intervals specified in the Maintenance
Booklet.Warning!
G
Have brake pad replacement and other work
on the electrohydraulic brake system car-
ried out by qualified technicians only. Con-
tact your Mercedes-Benz Center for further
information. The electrohydraulic brake sys-
tem must be deactivated prior to working on
the system. High pressure is intermittently
built up in the system as part of its automat-
ic self-test. In addition, the system is auto-
matically activated when the vehicle is
unlocked by remote control, when the driver
or passenger door is opened, when the
SmartKey in the starter switch is turned to
position1, when the brake pedal is de-
pressed or when the parking brake is re-
leased.
Failure to deactivate the system prior to
maintenance will cause brake pistons to ex-
tend and brake fluid to leak, which may re-
sult in injuries (contusions and acid burns),
see “Electrohydraulic brake system”
(page 84).
