When working on the RBS, certain
precautions must be taken, e.g. when putting
the brake system back into service.
Contact an authorized Mercedes-Benz
Center. Service conducted by qualified
technicians is required particularly for safety-
relevant work and work on safety-relevant
systems such as the RBS.
i For more information on the braking
system and for driving instructions, refer to
the Operator’s Manual.
BAS (Brake Assist System)
If you apply the brakes very quickly, the RBS
provides full brake boost as fast as possible.
In doing so, less brake pedal pressure than
usual is required and the brake pedal travel is
longer.
XApply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
i For more information on the BAS, refer to
the Operator’s Manual.
Driving systems
Cruise control/DISTRONIC PLUS*
When the cruise control or the DISTRONIC
PLUS brake the vehicle, the brake pedal is not
depressed.
For information on driving with the
DISTRONIC PLUS, see ( Y page 18).
i For more information on the cruise
control and the DISTRONIC PLUS, refer to
the Operator’s Manual.
