As soon as the vehicle starts to swerve
(understeer/oversteer), engine output is
reduced and the wheels are braked
individually. This considerably improves
the driving stability of the vehicle on
slippery road surfaces.
Plus
ESP® is ready for operation as soon
as the ignition is switched on and control
indicator v goes out.
Plus
When ESP® comes into action, v
flashes.
The vehicle is now in a critical situation;
Plus
ESP® allows you to keep control of
the vehicle and reminds you to match your

9 Warning
Do not let this special safety feature
tempt you into taking risks when driving.
Traffic safety can only be achieved by
adopting a responsible driving style.
Adapt speed to the road conditions.
Control indicator v
The control indicator illuminates for a few
seconds after the ignition is turned on. The
system is ready for operation when the
control indicator goes out.
Flashing during driving:
This shows the system has come into
action. The engine output may be reduced
(the sound of the engine changes) and the
vehicle may be braked automatically to a
small degree.
Driving and Operation
Illuminates while driving:
Fault in the system. Driving can be
continued. Poor road surface conditions
may however still cause vehicle stability
to be impaired.
Have the cause of the fault eliminated by
a workshop. The self-diagnosis integrated
into the system allows rapid fault
identification.
Control indicator v may illuminate when
the temporary spare wheel is in use.
The system is then deactivated.
Illuminates after interruption of power
supply e.g. after disconnecting battery.
After a power supply interruption the
steering angle sensor must be calibrated
to make the system operational:
z Automatic calibration by driving in
straight line at constant slow speed, i.e.
12 to 25 mph (20 to 40 km/h), on a level,
dry road,
z Manual calibration by turning steering
wheel from limit position to limit position.
If the control indicator does not go off after
successful calibration, observe notes in
previous column.
