If the electro-hydraulic brake system is
activated as the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you
may also feel the brake pedal pulsate
and you may hear a sound which is
caused by the activation of the elec-
tro-hydraulic brake system pump. This
is normal and not an indication of a
malfunction. Pedal travel returns to
normal when you release the brake
pedal and the sound soon ceases.

If you experience the above while driv-
ing and the red brake warning lamp
(

page 334) illuminates and/or warn-

ing messages appear in the multifunc-
tion display (

page 361), the brake

system is malfunctioning. Follow the in-
structions of the warning message(s)
and have the brake system checked
immediately.

Warning!

G

Have brake pad replacement and other work

on the electro-hydraulic brake system car-

ried out by qualified technicians only. Con-

tact an authorized Mercedes-Benz Center

for further information. The electro-hydrau-

lic brake system must be deactivated prior

to working on the system. 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 passenger 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 park-

ing brake is released. Failure to deactivate

the system prior to maintenance will cause

brake pistons to extend and brake fluid to

leak, which may result in injuries (contu-

sions and acid burns). Extended brake pis-

tons may also cause injury.
