er with the SOS button and the Roadside
Assistance button•).
See system self-check (
page 309) if the indi-
cator lamp does not come on in red or stays on
longer than approximately 10 seconds.
If the indicator lamp in the Information
button¡ is flashing continuously and there
was no voice connection to the Response Center
established, then the Tele Aid system could not
initiate an Information call (e.g. the relevant cel-
lular phone network is not available). The mes-
sage
Call failed

display.
Information calls can be terminated using
thet button on the multifunction steering
wheel or the END button on the COMAND sys-
tem.

If the indicator lamps do not start flashing
after pressing one of the buttons or remain illu-
minated (in red) at any time, the Tele Aid system
has detected a malfunction or the service is not
currently active, and may not initiate a call. Visit
your authorized Mercedes-Benz Light Truck
Center and have the system checked or contact
the Response Center at 1-800-756-9018 (in the
USA) or 1-888-923-8367 (in Canada) as soon as
possible.

ment cluster fails to come on during thebulb self-check when switching on the
ignition, have the respective bulb checked
and replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp
comes on while the engine is
running.
ABS has detected a malfunction and has
switched off. The BAS, ESP
®, EBP and 4-ETS
are also switched off (see messages in multi-
function display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as the navigation
system* or the automatic transmission may
also be malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 428).
Have the system checked at an
authorized Mercedes-Benz Light
Truck Center as soon as possible.
Failure to follow these instructions
increases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery might not be charged sufficiently.
When the voltage is above this value
again, the ABS is operational again and
the ABS indicator lamp should go out.
If the ABS indicator lamp should go out:
Have the generator (alternator) and
the battery checked.
