Stop-start system 3 116.Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has:
n=cooling4=air recirculation
Heated seats ß 3 38, Heated
steering wheel * 3 71.
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) as soon as the
outside temperature is slightly above
the freezing point. 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
might inhibit Autostops.
Notice
If the climate control is set to
maximal cooling while the ambient
temperature is high, an Autostop
may be inhibited until the requested
temperature in the passenger
compartment has been reached.
If the climate control is set to
maximal cooling while the engine is
in an Autostop, the engine may
restart automatically.

Air recirculation system 4
The air recirculation mode is operated with the 4 button.9Warning
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.
Air distribution to l: Air recirculation
is deactivated.
In warm and very humid ambient air conditions, the windscreen might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
Maximum cooling
Briefly open the windows so that hot air can disperse quickly.
■ Cooling n on.
■ Air circulation system 4 on.
■ Set temperature control to coldest level.
■ Set fan speed to highest level.

Cooling
Climate control111
In the Climate menu, select menu
item AC and activate or deactivate
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,
deactivate AC to save fuel.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
might inhibit Autostops.
Depending on the vehicle equipment, the display will indicate AC when
cooling is activated or Eco when the
cooling is deactivated.
On vehicles with stop-start system,
two settings for the operation of the
climate control system during an Autostop are available.
Select menu item ecoMode.
Select the desired setting: ■ Max AutoStop : In this mode the
electronic climate control is operated with focus on fuel
efficiency. The duration of an
Autostop is not limited.
■ AC Comfort : In this mode the
electronic climate control is
operated with focus on climate
condition. The duration of an
Autostop might be limited to
maintain the requested climate
condition.
Setting modifications are briefly
shown as pop-ups.
Selections are indicated by a o in
front of the menu item.
In either mode, an Autostop will be
available after the temperature in the
passenger compartment has
sufficiently cooled down.

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.
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 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

Control of the vehicleNever coast with engine not
running (except during an 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 3 116.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.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.
Control indicator c 3 82.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Driving and operating115Starting 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.
