Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has controls for:
n=cooling4=air recirculation
Heated front seats ß 3 35.
Cooling n
Press button n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press button n 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 the cooling system off to save
fuel.
Air recirculation system
Press button 4 to activate air
recirculation mode. Activation is
indicated by the LED in the button.
Press button 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. 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 V.
Maximum cooling
Briefly open the windows so that hot air can disperse quickly.
■ Cooling n on.
■ Air recirculation system 4 on.
■ Set air distribution control to M.
■ Set temperature control to coldest level.

The system can be manually adapted by use of air distribution and air flowcontrols.
The electronic climate control system
is only fully operational when the
engine is running.
For correct operation do not cover the
sensor on the instrument panel.

For reasons of comfort, change
temperature only in small increments. Turn AUTO knob to adjust.

mists up from outside, activate
windscreen wiper and deactivate V.Air vents
Adjustable air vents At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to lack of air movement.9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.

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.
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 outside
temperature is too low.
Service For optimal cooling performance, it isrecommended that the climate control
system be checked annually, 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

Control of the vehicleNever 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. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 103.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.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.

Autostop
During an Autostop, the engine is
restarted automatically by depressing the clutch pedal. Vehicles with
manual transmission automated
(MTA): shift to a forward gear, release
brake pedal or move lever to +, – or
R to enable an automatic restart.
Stop-start system 3 103.
Starting the vehicle at low
temperatures The start of 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 battery.
