The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or sub-

erations under

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 operating guide
for operation of the external audio source.
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.
