air flow.
The system can be manually adapted by use of air distribution and air flow
controls.
The electronic climate control system
is only fully operational when the
engine is running.
For correct operation do not cover the
sensor on the instrument panel.

Basic setting for maximum comfort: ● Press AUTO ("AUTO" appears in
the display).
● Set desired temperature (the temperature appears in the
display).
● Open all air vents.

Heating will not be fully effective until
the engine has reached normal
operating temperature.
If the minimum temperature of 15 ℃
is set, the electronic climate control
system runs at maximum cooling.
If the maximum temperature of 27 ℃
is set, the electronic climate control

116Climate controlCoolingThe air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level.
Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required
press A/C OFF to switch the cooling
system off, thus saving fuel.
" A/C OFF " appears in the display.
Manual air recirculation mode Press u. LED illuminates and u
appears in the display.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.
To return to automatic mode: press
u or AUTO .
Rear 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).

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.
