See Operator’s Manual
The ESP
®
was deactivated because
of insufficient power supply. The
charging voltage has fallen below
10 volts.
The brake system is still functioning
normally but without the ABS
available.
When the voltage is above this value again, the
ABS is operational again and the message in the
multifunction display should disappear.
If the message in the multifunction display does
not disappear:
̈ Have the generator (alternator) and the
battery checked.
If the yellow ESP
®
warning
lamp v flashes while driving and
this message appears, the electron-
ic traction system has switched off
to prevent overheating of the drive
wheel brakes.
As soon as the brakes have cooled off, the
electronic traction system switches on again.
The message in the multifunction display disap-
pears and the ESP
®
warning lamp v goes
out.
The self-diagnosis has not been
completed yet.
The display will clear after driving a short
distance at a vehicle speed of above
12 mph (20 km/h).
