General information
The phone function provides you with
the possibility of having mobile phone
conversations via a vehicle
microphone and the vehicle
loudspeakers as well as operating the most important mobile phone
functions via the Infotainment system
in the vehicle. To be able to use the
phone function, the mobile phone
must be connected to the
Infotainment system via Bluetooth.
Not all phone functions are supported by every mobile phone. The usable
phone functions depend on the
relevant mobile phone and network
provider. You can find further
information on this in the operating
instructions of your mobile phone, or
you can enquire about them with your
network provider.Important information for
operation and traffic safety9 Warning
Mobile phones have effects on
your environment. For this reason safety regulations and directions
have been prepared. You should
be familiar with the related
directions before you use the
telephone function.
9 Warning
Use of the hands-free facility while
driving can be dangerous because
your concentration is reduced
when telephoning. Park your
vehicle before you use the hands- free facility. Follow the stipulations
of the country in which you find

Emergency call9 Warning
Connection setup cannot be
guaranteed in all situations. For
this reason you should not rely
exclusively on a mobile phone
when a vitally important
communication (e.g. a medical
emergency) is concerned.
In some networks it may be
necessary for a valid SIM card to
be properly inserted in the mobile
phone.
9 Warning
Bear in mind that you can make
and receive calls with the mobile
phone if it is in a service area with
a sufficiently strong signal. Under
certain circumstances,
emergency calls cannot be made
in all mobile phone networks;
problems may occur when certain
network services and / or
telephone functions are active.
You can enquire about this with
the local network operators.
The emergency call number can
differ depending on the region and
country. Please enquire
beforehand about the correct
emergency call number for the
relevant region.
Making an emergency call
Dial the emergency call number (e.g.
112 ).

Installation instructions and
operating guidelines
The vehicle specific installation
instructions and the operating
guidelines of the mobile phone and
hands-free manufacturer must be
observed when installing and
operating a mobile telephone. Failure to do so could invalidate the vehicle
type approval (EU directive 95/54/
EC).
Recommendations for fault-free
operation:
● Professionally installed exterior antenna to obtain the maximum
range possible
● Maximum transmission power 10 W
● Installation of the phone in a suitable spot, consider relevant
Note in the Owner's Manual,
section Airbag system .Seek advice on predetermined
installation points for the external
antenna or equipment holder and
ways of using devices with a
transmission power exceeding 10 W.
Use of a hands-free attachment
without external antenna with mobile
telephone standards GSM
900/1800/1900 and UMTS is only
permitted if the maximum
transmission power of the mobile
telephone is 2 W for GSM 900 or
1 W for the other types.
For reasons of safety, do not use the
phone while driving. Even use of a hands-free set can be a distraction
while driving.9 Warning
Operation of radio equipment and
mobile telephones which fail to
meet above mentioned mobile
telephone standards is only
permitted using an antenna
located outside of the vehicle.
Caution
Mobile telephones and radio
equipment may lead to
malfunctions in the vehicle
electronics when operated inside
the vehicle with no exterior
antenna, unless the above
mentioned regulations are
observed.

functional when the engine is running and climate control fan is switched on.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
may inhibit autostops.

The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen

windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check

first gear or set the selector
lever to position P before
removing the ignition key. On
an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key. Turn the front wheels
towards the kerb.
● Close the windows.
