Driving safety systems
The SBC brake system is automatically ac-
tivated when you:
unlock the vehicle with the SmartKey
or the KEYLESS-GO**
open the driver’s or passenger door
turn the SmartKey in the starter
switch to position 1
in vehicles with KEYLESS-GO**, press
the start/stop button (
page 55) on
gear selector lever once
depress the brake pedal
release the parking brake
i
If the SBC brake system is activated
when the brake pedal is first de-
pressed, you may feel a reduced ped-
al 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 activa-
tion of the SBC pump. This is normal
and not an indication of a malfunc-
tion. Pedal travel returns to normal
when you release the brake pedal
and the sound soon ceases.
If you experience the above while
driving and the red brake warning
lamp (
page 388) illuminates and/or
warning messages appear in the in-
strument cluster (see page 400 to
page 401), the brake system is mal-
functioning. Follow the instructions
of the warning message(s) and have
the brake system checked immedia-
tely.
Warning! G
Have brake pad replacement and other
work on the SBC brake system carried out
by qualified technicians only. Contact an
authorized Maybach Studio for further in-
formation. The SBC 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 auto-
matically activated when the vehicle is un-
locked by remote control, when the driver
or passenger door is opened, when the
starter switch is in position 1, 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.
