Display message Possible cause/consequence Possible solution
ESP Unavailable
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 ESP
®
available.
When the voltage is above this value again, the
ESP
® 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.
̈ Have the system checked at an authorized
Mercedes-Benz Light Truck Center as soon
as possible.
If the yellow ESP ® warning
lamp v flashes while driving
and this message appears, the
Electronic 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).
