Audio system
Calling up AUX mode
Press and hold Q button until AUX
appears in the display.
The device connected with the external
audio source cinch-connector is heard,
provided it is switched to playback.
You can adjust the volume (
page 216),
the sound settings (

volume distribution (
page 218) for the
AUX input.
The following settings can be made in the
audio AUX mode:
Volume (page 216)
Sound settings (page 216)
Volume distribution (page 218)Canceling AUX mode
Press any audio source button.
The AUX mode is canceled.
Warning!G
Only operate an external audio source (AUX)
when the vehicle is stationary. There is a risk
of accident by being distracted from road
and traffic conditions if you operate an ex-
ternal audio source (AUX) while the vehicle
is in motion.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is
covering a distance of 44 feet
(approximately 14 m) every second.
Warning!G
Due to the different volumes of the external
audio sources, system messages (e.g. traffic
and navigation announcements) may be
much louder. You may need to disable these
system messages or adjust the volume of
these messages manually.
iPlease refer to the relevant manufacturers
operating instruction for the external audio
source device.
iThe volume of external audio sources is ex-
tremely variable. It is possible that a device con-
nected as an external audio source will sound
quieter or louder in the vehicle or that the usual
maximum volume cannot be achieved. On cer-
tain devices the volume can be set separately. In
this case, start at a moderate volume and in-
crease it slowly. In this way, you can determine
whether the system is capable of playback with-
out distortion, even at high volume.

Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.
ProblemPossible cause/consequenceSuggested solution
-The yellow ABS indicator lamp
comes on while the engine is
running.The ABS has detected a malfunction and has
switched off. The BAS and the ESP® are also
switched off (see messages in the multifunc-
tion display).
The brake system is still functioning normally
but without the systems specified above.
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 will lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 394).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off. The BAS
and the ESP
® are also switched off (see mes-
sages in the multifunction display)
The battery might not be charged sufficiently.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.
