Stop-start system 3 115.Manual settings
Manually changing any of the
following settings will deactivate
Automatic mode:
Fan speed Z
Adjust the air flow manually by
switching the fan to the desired
speed.
If the fan is switched off, the air
conditioning is also deactivated.
Air distribution M
Press appropriate button for desired
adjustment. LED illuminates in the
button when activated.R=to windscreen and front door
windows.M=to head area.S=to foot well.
Combinations of settings are possible
by pressing two buttons until both
LEDs are illuminated.
To return to Automatic mode: Press
AUTO button.
Cooling AC
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.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 110.
If no cooling or drying is required press the AC OFF button to switch the
cooling system off, thus saving fuel.
LED illuminates in the button.
To return to Automatic mode: Press
AUTO button.
Air recirculation mode u
Activate or deactivate manual air recirculation mode with the u button.
LED illuminates in the button when
activated.
Climate control1039Warning
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.
To return to Automatic mode: Press
AUTO button.
Rear heating system
The rear passenger compartment
heating fan assists air flow to the rear
passenger compartment via the rear
air vents.
The rate of air flow is determined by
the fan. Air temperature is controlled
using the temperature control on the
instrument panel.
Rear air conditioning
system
The rear air conditioning system is
actuated in conjunction with the front
passenger compartment air
conditioning system.
108Climate controlAir 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.
Centre air vents
To open or close the centre air vents
and direct the flow of air, tilt the slats
up or down and turn the adjuster
wheel left or right.
Side air vents
To open or close the side air vents, tilt the slats up or down.
Direct the flow of air by rotating the
vents.
Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
Rear air vents
Depending on vehicle, additional
adjustable air vents are located in the
rear passenger compartment.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows, in the foot wells and,
depending on vehicle, in the rear passenger compartment.
Glovebox cooler
The air conditioning system can also
keep the contents of the glovebox
cool.
Driving and operating113
At very low outside temperatures
(e.g. below -10 °C) keep the clutch
pedal depressed while pressing the
Start/Stop button until the engine
starts.
If one of the starting conditions is not
applied, a corresponding message
appears in the Driver Information
Centre 3 88.
Vehicle messages 3 89.
Engine stop Electronic key must be inside the
vehicle, either in the card reader or
the front passenger compartment.
With the vehicle stationary, press the
Start/Stop button to stop the engine.
The steering wheel lock is engaged
when the driver's door is opened and the vehicle is locked.
If the electronic key is not detected, a
corresponding message appears in
the Driver Information Centre 3 88 . In
this event, press the Start/Stop button
for 2 seconds to stop the engine.
Central locking system 3 23.Retained power off
Press the Start/Stop button for more
than two seconds; the engine is
stopped while some functions, e.g.
Infotainment system, are available for
use for approx. 10 minutes.
These functions stop working when
the driver's door is opened and the
vehicle is locked.
Notice
Always take the electronic key with you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 89 and a message in the
Driver Information Centre 3 89 when
the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
■ Fault in electronic key.
■ Electronic key out of reception range.
■ Battery voltage too low.
■ Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
■ Interference from higher-power radio waves from other sources.
Battery replacement 3 19.
Central locking system 3 23.
Electronic key system 3 21.
118Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by the illumination of control
indicators F 3 84 and Z 3 84 in the
instrument cluster. Seek the
assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 132, 3 180 could
damage the catalytic converter or
electronic components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Vehicle care137
■ Open the bonnet, close all doorsand lock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are
not functional, e.g. anti-theft alarm
system.
Putting back into operation
When the vehicle is to be put back into
operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plate, if necessary.End-of-life vehicle

authorised recycling centre.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
9 Danger
The ignition system generates
extremely high voltages. Do not
touch.
The caps for topping up the engine oil, the coolant, the washer fluid and the
oil dipstick handle are yellow for ease
of identification.
