Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:A/C:cooling4:air recirculation
Heated seats 3 50.
Cooling (A/C)
Press A/C to switch on cooling.
Activation is indicated by illumination
of the LED in the button. 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 above a
specific level. 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 an Autostop.
Stop-start system 3 137.
Note
Air conditioning performance is
reduced when ECO mode has been
activated 3 131.
Air recirculation system 4
Press 4
to activate air recirculation
mode. Activation is indicated by
illumination of the LED in the button.
Press 4 again to deactivate air
recirculation mode.
120Climate control9Warning
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 might mist up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and avoid the use
of air distribution settings J and V.
Maximum cooling
Briefly open the windows so that hot air can disperse quickly.
● Cooling A/C on.
● Air recirculation system 4 on.
● Set air distribution control to M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all air vents.

Climate control121The preselected temperature is
automatically regulated. In Automatic
mode, the fan speed and air
distribution automatically regulate the
air flow.
The system can be manually adapted via the use of air distribution and air
flow controls.
Electronic climate control system is only fully operational when the engine is running.
Automatic mode AUTO Basic setting for maximum comfort: ● Switch on the fan.
● Press AUTO: fan speed, air
distribution, cooling and air
recirculation are regulated
automatically.
● Set the desired temperature.
● Open all air vents.
To switch off the electronic climate
control system, switch off the fan.
Temperature preselection Temperatures can be set to the
desired value.If the minimum temperature is set, the
climate control system runs at
maximum cooling.
If the maximum temperature is set,
the climate control system runs at maximum heating.
Demisting and defrosting the

● Press Ê: LED illuminates in the
button when activated.
● Temperature, air distribution and cooling are regulated
automatically and the fan runs at

To return to Automatic mode: press Ê or AUTO .
Note
If Ê is pressed while the engine is
running, an Autostop will be inhibited until Ê is pressed again.
If Ê is pressed while the engine is in
an Autostop, the engine will restart
automatically.

The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is above a
specific level. Therefore
condensation may form and drip from under the vehicle.
Note
Air conditioning performance is
reduced when ECO mode has been
activated 3 131.
If no cooling or drying is required
press A/C OFF to switch the cooling
system off, thus saving fuel. LED
illuminates in the button.
To return to Automatic mode: Press

Air recirculation mode u
Activate or deactivate manual air recirculation mode with u. LED
illuminates in the button when
activated.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 from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
To return to Automatic mode: Press
AUTO button.
Rear heating system
The rear passenger compartment
heating fan assists air flow to the rear
passenger compartment via the rear
air vents.
The rate of air flow is determined by
the fan. Air temperature is controlled
using the temperature control on the
instrument panel.
130Climate controlRear air ventsDepending on vehicle, additional
adjustable air vents are located in the
rear passenger compartment.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows, in the foot wells and,
depending on vehicle, in the rear
passenger compartment.
Glovebox cooler The air conditioning system can alsokeep the contents of the glovebox
cool.Maintenance
Air intake The air intake in front of the
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 outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
3 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
Note
Refrigerant R-134a contains
fluorinated greenhouse gases with a global warming potential of 1430.
Front air conditioning system is filled
with 0.58 kg and has a CO 2
equivalent of 0.83 tonnes, the front
and rear air conditioning system is
filled with 0.88 kg and has a CO 2
equivalent of 1.26 tonnes.
Depending on vehicle, information
regarding air conditioning refrigerant
appears on a label located in the
engine compartment.
Driving and operating135These functions stop working when
the driver's door is opened and the vehicle is locked.
Note
Always take the electronic key with
you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 105 and a message in the
Driver Information Centre 3 104
when the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
● Fault in electronic key.
● Electronic key out of reception range.
● Battery voltage too low.
● Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
Battery replacement 3 22.
Central locking system 3 26.

Starting the engine
Manual transmission: operate clutch.
Do not accelerate.
Diesel engines: turn the key to
position 2 for preheating until control
indicator ! extinguishes in the
instrument cluster 3 101.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal.
