– To go up slopes where each traction wheel is on a surface with a
very different grip (I.e. ice on the left, dry asphalt on the right). The
EDS continues to function under these conditions.
Afterwards you should always reconnect this device.

For the TCS to work properly all four wheels should be the same. Otherwise
engine performance may be reduced.

The ESP increases the control over the vehicle in situations such as
accelerating or in turns.
The ESP expands the functions of the ABS/TCS and decreases
under any circumstance the risk of skidding. This contributes to an
improved stability of the vehicle.The system works in the realm of speed in relation to the ABS. In
case of a failure of the ABS, the ESP will also fail.
The ESP connects automatically when the engine is switched on
and checks itself.
If needed, the system can be switched on or off by pressing the
button.
When the system is off, the ESP warning light will light up
⇒
"Warning lights" chapter.
The ESP should always be connected. Only in exceptional cases,
when the skidding effect is desired under extremely sporty
conditions, the system can be disconnected.
Afterwards the system should be reconnected.
The ABS and EDS
⇒"Switches" chapter remain connected even
when the ESP is off.

The electronic stability program encompasses the ABS, EDS and
TCS. In addition to all available data for these functions, the ESP
control unit needs additional measurements supplied by high
precision sensors. The measuring data consists of the speed at
which the vehicle turns around its vertical axis, acceleration,
pressure on brakes and the turn of the steering wheel.
With the help of the steering wheel sensor and the vehicle’s
speed, the desired direction is determined and constantly
compared to the vehicle’s real behavior. When differences occur,
such as incipient skidding, the ESP automatically brakes the
adequate wheel.
