Brake lining 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 SBC brake system carried out by
qualified technicians only. Contact your
Mercedes-Benz Center for further informa-
tion. The SBC brake system must be deacti-
vated prior to working on the system. High
pressure is intermittently built up in the sys-
tem as part of its automatic self-test. In ad-
dition, the system is automatically activated
when the vehicle is unlocked by remote con-
trol, when the driver or passenger door is
opened, when the SmartKey in the starter
switch is turned to position1, when the
brake pedal is depressed or when the park-
ing brake is released.
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 “SBC brake system” (
page 84).
