108Climate controlDuring automatic mode, the settings
for fan speed, air distribution, air
conditioning and air recirculation are
automatically regulated by the system and are not shown on the display.
Temperature preselection
Temperatures can be set to the
desired value with the 2 buttons
below the display.
For reasons of comfort, change
temperature only in small increments.red:warmblue:cold
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
system runs at maximum heating.
Notice
If the temperature is to be reduced
for climate comfort reasons, an
Autostop can be inhibited or the
engine will restart automatically
when cooling is switched on.
Stop-start system 3 122.
Fan speed
Fan speed can be increased or
decreased with the x buttons.
The selected fan speed is indicated
with x in the display.
If the fan is switched off the air
conditioning is also deactivated.
To return to automatic mode: Press

Climate control109CoolingThe 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.
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).
Setting the time and day
Press Ö until the time display flashes.
If the vehicle battery supply has been
interrupted prior to its use, press m
or n briefly to make the time display
flash.
Adjust the time by pressing m or n .
The time is set when the displayed
time stops flashing.
The display for the day will then flash: adjust the day by pressing m or n .
The day is set when the display stops
flashing.

Driving and operating123
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and brake performance will be
maintained. Brake assist, however, is
not available 3 139.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed or the driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an Autostop
● the brake vacuum is sufficient ● the self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See "Climate control" chapter for
further information 3 105.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.
New vehicle running-in 3 120.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
