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 occupants to

In warm and very humid ambient air
conditions, the windscreen may mist
up from outside when cold air is

Air conditioning regularoperation
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
● cabin air filter check

136Driving and operatingAutomatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Press and release Start/Stop: an
automatic procedure operates the
starter with a short delay until the
engine is running.
Before restarting or to switch off the engine when vehicle is stationary, press Start/Stop once more briefly.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 137.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 137.
Emergency shut off during driving If the engine needs to be switched offduring driving in case of emergency,
press Start/Stop for five seconds.9Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down the engine and ignition while
driving only when required in case of emergency.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged vehicle battery.
With temperatures below -30 °C the
automatic transmission requires a
warming phase of approx.
five minutes. The selector lever must
be in position P.
Heating functionalities
Notice
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
