Brake pad thickness must be visually inspected by a qualified technician at the intervals specified in the Maintenance Booklet.
G
Warning!
Have brake pad replacement and other
work on the electro-hydraulic brake system
carried out by qualified technicians only.
Contact an authorized Mercedes-Benz Cen-
ter for further information.
The electro-hydraulic brake system must
be deactivated prior to working on the sys-
tem. High pressure is intermittently built up
in the system as part of its automatic self-
test.
In addition, the system is automatically
activated when the vehicle is unlocked by
remote control, when the driver or passen-
ger door is opened, when the SmartKey in
the starter switch is turned to position 1 or
the KEYLESS-GO start/stop button is
pressed once, when the brake pedal is
depressed or when the parking brake is
released. Failure to deactivate the system
prior to maintenance will cause brake pis-
tons to extend and brake fluid to leak,
which may result in injuries (contusions and
acid burns). Extended brake pistons may
also cause injury.

parts and the brake fluid catching fire. You can be seriously burned.
