Cooling n
Press n 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 n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
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 Autostops.
Stop-start system 3 133.
Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.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.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
● Switch on cooling n.
● Air recirculation system 4 on.
● Press air distribution switch M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.

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.
Air conditioning with the engine
not running
When ignition is off, the residual heat
or cooling in the system can be used for climate control in passenger
compartment.
Auxiliary heater Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Air vents
Adjustable air vents At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel to the right. Adjust the air
amount at the vent outlet by turning
the adjuster wheel.
Page 128 of 247

126Climate control
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel to the left.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.
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 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
