The Infotainment system provides
you with state-of-the-art in-car
infotainment.
Using the FM, AM or DAB radio
functions, you may register up to 36 stations on six favourites pages.
The integrated audio player will
entertain you with audio CDs and
MP3/WMA CDs.
You can connect external data
storage devices, e.g. iPod, MP3
player, USB stick, or a portable CD
player to the Infotainment system as
further audio sources; either via cable or via Bluetooth.
In addition, the Infotainment system is equipped with a Phone portal that
allows for comfortable and safe use of
your mobile phone in the vehicle.
Optionally, the Infotainment system
can be operated using controls on the steering wheel.
The well-thought-out design of the
control elements and the clear
displays enable you to control the
system easily and intuitively.Notice
This manual describes all options
and features available for the
various Infotainment systems.
Certain descriptions, including those
for display and menu functions, may not apply to your vehicle due to
model variant, country
specifications, special equipment or
accessories.
Important information on
operation and traffic safety9 Warning
The Infotainment system must be
used so that the vehicle can be
driven safely at all times. If in
doubt, stop the vehicle and
operate the Infotainment system
while the vehicle is stationary.
