Driving safety systems
The electro-hydraulic brake system is au-
tomatically activated when you:
앫 unlock the vehicle with the SmartKey
or the KEYLESS-GO**
앫 open the driver’s or passenger door
앫 turn the SmartKey in the starter
switch to position 1
앫 in vehicles with KEYLESS-GO**, press
the start/stop button (
컄 page 61) on
gear selector lever once
앫 depress the brake pedal
앫 release the parking brake
i If the electro-hydraulic brake system is ac-
tivated when the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than nor-
mal. 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 electro-hydraulic brake system pump. This
is normal and not an indication of a malfunc-
tion. Pedal travel returns to normal when you
release the brake pedal and depress it again
and the sound soon ceases.
If you experience a reduced pedal resistance
and longer pedal travel while driving and the
red brake warning lamp (컄 page 360) illumi-
nates and/or warning messages appear in the
instrument cluster (see page 378 to page 381),
the brake system is malfunctioning. Follow
the instructions of the warning message(s)
and have the brake system checked immedia-
tely.
The electro-hydraulic brake servo assis-
tance switches off automatically:
앫 approximately 20 seconds after you
locked the vehicle from outside
앫 approximately 2 minutes after you
앫 turned the SmartKey in the starter
switch to position 0 or removed
the SmartKey
앫 pressed the KEYLESS-GO** start/
stop button (
컄 page 61) to turn
off the engine or power supply
and opened the driver’s door
(with driver’s door open, the start-
er switch is set to position 0, same
as SmartKey removed from starter
switch)
Warning! G
Have brake pad replacement and other
work on the electro-hydraulic brake sys-
tem carried out by qualified technicians
only. Contact an authorized Maybach Stu-
dio for further information. The electro-
hydraulic brake system must be deactivat-
ed 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 acti-
vated when the vehicle is unlocked by re-
mote control, when the driver’s or
passenger door is opened, when the start-
er switch is in 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 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.
