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.
9 Warning
In some areas one-way streets
and other roads and entrances
(e.g. pedestrian zones) that you
are not allowed to turn into are not marked on the map. In such areas
the Infotainment system may
issue a warning that must be
accepted. Here you must pay
particular attention to one-way
streets, roads and entrances that
you are not allowed to drive into.
Radio reception
Radio reception may be disrupted by
static, noise, distortion or loss of
reception due to:
● changes in distance from the transmitter
● multipath reception due to reflection
● shadowing
Theft-deterrent feature
The Infotainment system is equipped
with an electronic security system for
the purpose of theft deterrence.
The Infotainment system therefore
functions only in your vehicle and is
worthless to a thief.
