Climate control133Set temperatures to the desired
value. The knob on the passenger side changes the temperature for the
passenger side.The knob on the
driver's side changes the temperature
for the driver's side or for both sides
depending on activation of
synchronisation SYNC.
The selected temperature is indicated in the display of the knob.
If the minimum temperature Lo is set,
the climate control system runs at maximum cooling, if cooling A/C is
switched on.
If the maximum temperature Hi is set,
the climate control system runs at maximum heating.
Notice
If A/C is switched on, reducing the
set cabin temperature can cause the
engine to restart from an Autostop or inhibit an Autostop.

Climate control135Cooling 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) 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. When the cooling
system is switched off, no engine
restart will be requested by the
climate control system during an
Autostop. Exception: defrost system
is activated and outside temperature
above 0 °C requests a restart.
The display will indicate A/C ON when
cooling is activated or A/C OFF when
the cooling is deactivated.
Activation or deactivation of cooling
operation after engine start can be
changed in the Settings menu in the
Info-Display. Vehicle personalisation

Manual air recirculation 4Press 4 to activate the air
recirculation mode. Activation is
indicated by illumination of the LED in
the button.
Press 4 again to deactivate
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.
Climate control137Maintenance
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.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
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

Driving and operating139Driving hints
Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation ( e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
Stop-start system 3 144.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by
an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Use only floor mats, which fit properly
and are fixed by the retainers on the
driver side.
Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
battery.
