open sliding doors may move
accidentally on account of their
weight.
Close the sliding doors before
driving off.

156Infotainment systemDisconnecting from USB socketPlayback is stopped immediately
when the audio device is withdrawn
from the USB socket.Bluetooth music
General information
Bluetooth-enabled auxiliary audio sources (e.g. music mobile phones,
MP3 players etc.) can be connected
wirelessly to the Infotainment system.
Important information ● The Infotainment system only connects to Bluetooth devices
that support A2DP (Advanced
Audio Distribution Profile).
Connection issues may arise with early versions.
● The Bluetooth device must support AVRCP (Audio VideoRemote Control Profile)
version 1.0 or higher. If the
device does not support AVRCP, only the volume can be controlled via the Infotainment system.
● Before connecting the Bluetooth device to the Infotainment
system, become acquainted with
its operating instructions for
Bluetooth functions.Operation
Prerequisites The following prerequisites must be
met, in order to control a Bluetooth-
enabled audio device via the
Infotainment system:
● The Bluetooth function of the Infotainment system must be
activated.
Refer to "Bluetooth connection"
in the "Phone" section 3 197.
● The Bluetooth function of the Bluetooth-enabled auxiliary
audio source must be activated
(see audio device operating
instructions).
● Dependent upon the audio source, it may be required to set
that device to "visible" (see audio
device operating instructions).
● The audio source must be paired
and connected to the
Infotainment system.

216Climate controlCombi
Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in use, to prevent ice forming in the
system due to lack of air movement.
Auxiliary heater Coolant heater
The engine-independent, fuel-
powered coolant heater provides rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units
The timer or remote control unit turns the system on and off, and is used to
programme specific departure times.
