Safety and Security
Driving safety systems
The electro-hydraulic brake servo assis-
tance switches off automatically
ț approximately 2 minutes after you
turned the SmartKey in the starter
switch to position 0 or removed the
SmartKey
ț approximately 20 seconds after you
locked the vehicle from the outside
Notes on driving with the
electro-hydraulic brake system
ț Following extended periods of only mi-
nor loads to your brake system, you
should occasionally apply the brakes
when traveling at high speeds. This im-
proves the grip of the brake pads and
prevents possible brake noise.
ț After driving on wet or snow-covered
roads, you should apply your brakes
firmly before parking your vehicle. This
produces heat which serves to dry the
brake disks.
ț On long and steep grades, shift to a
lower gear (gear range 1, 2, or 3) to
prevent the brakes from overheating
and to reduce brake wear.
ț After hard braking, it is advisable to
drive on for some time so that the air
stream will cool down the brakes
faster.
ț Only Mercedes-Benz approved compo-
nents (e.g. brake pads) should be
installed on your vehicle. Brake pads
not approved by Mercedes-Benz may
impair the safety of your vehicle.
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, 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.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
