Installation instructions and
operating guidelines
The vehicle specific installation
instructions and the operating
guidelines of the mobile phone and
handsfree 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 ten watts
● 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 andways of using devices with a
transmission power exceeding
ten watts.
Use of a handsfree 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 two watts for GSM 900
or one watt for the other types.
For reasons of safety, do not use the
phone while driving. Even use of a handsfree set can be a distractionwhile 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.

Air conditioning system
Cooling (A/C)Press A/C to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running and climate control fan is switched on.
Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is a little above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Note
If the climate control is set to
maximum cooling while the ambient temperature is high, an Autostop
may be inhibited until the required
temperature in the passenger
compartment has been reached.
If the climate control is set to
maximum cooling while the engine is in an Autostop, the engine may
restart automatically.

9 Warning
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. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.

Climate control213Rear heating system
If the engine is switched off, the rear
compartment can be heated by the
additional heating, through low level
vents.
By programming values using the
control panel, the user can adjust the
time, day and temperature settings.
Heating will cease to operate if the
vehicle fuel level drops too low.
During operation, power from the
vehicle battery is used. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
Note
If the rear heating system is
activated while the engine is
running, an Autostop will be
inhibited.
To ensure efficient performance, the
low level air vents in the rear
passenger compartment must not be
obstructed.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
9 Warning
If the warning light illuminates in
combination with the hazard
warning flashers, stop vehicle and switch off engine as soon as
possible. Evacuate the vehicle, there is a risk of fire.
