Sprinter 906
EBD
- electronic brake force distribution:
This system helps to prevent the rear wheels from locking before the front wheels, when braking.
ABS
– anti-lock braking system:
Helps to prevent the wheels from locking.
ASR
– acceleration skid control:
Regulates wheel spin by intervening in the engine management and by braking the driving
wheels. A deactivation switch allows engine intervention to be switched off at lower speeds and
the slip threshold to be raised.
BAS
– Brake Assist:
If an emergency braking situation is detected, this system actively increases braking pressure up
to the slip threshold.
ROM
- Roll Over Mitigation:
This system helps to detect rollover tendencies during maneuvers with low road speed and high
lateral acceleration.
RMI
- Roll Movement Intervention:
This system helps to detect rollover tendencies in dynamic maneuvers and in high-speed evasive
maneuvers with a high lateral acceleration.
LAC
- Load Adaptive Control:
The system helps determine the gross vehicle weight and supports the ESP control function,
depending on the vehicle load.
EUC
- Enhanced Understeering Control:
The system helps to stabilize the vehicle in the event of heavy under steer.
TSA - Trailer Stability Assist:
The system helps reducing trailer jackknifing in two phases. Sensors monitor the amplitude of the
swinging movements. As soon as they detect an unstable situation, a first stabilizing phase is
initiated, consisting in an asymmetrical braking intervention at the front axle, alternating on the left
and on the right sides. If this asymmetrical braking action proves insufficient, the second phase is
added
to the first. In this second phase the vehicle is slowed down by brake interventions at all
four wheels and by an engine torque reduction.
This system is active ex-factory if a trailer tow hitch is installed at the factory.

ESP
- Electronic Stability Program:
®
ESP
interfaces with both the brake system and the engine management. It continuously monitors
the signals from the steering angle sensor, wheel speed sensors, lateral acceleration sensor and
yaw sensor, allowing it to assist the driver if instability is detected. In critical situations, ESP
actively intervenes in the engine management and brake system and assists the driver by
generating braking forces to restore directional stability. When ESP
®
taking place, the ESP
warning light comes on in the speedometer.
If acceleration skid control is deactivated by pressing the ASR-OFF switch, the ESP
comes on continuously. If a driving situation occurs in which instability is detected, ESP
intervenes and ASR is switched back on again. At speeds over 60 km/h [37mph] ASR is always
active, i.e. if the system has been deactivated it is automatically reactivated when the vehicle
accelerates to a speed above 60 km/h and cannot be deactivated. When the speed falls below
60 km/h [37mph], ASR is deactivated again and the warning light comes on.
Even with ASR switched off, the ESP
friction limit.
