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).
