Cooling n
Press 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 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.
Activated cooling may inhibit
Autostops. Stop-start system 3 116.
Air recirculation system Press 4 to activate air recirculation
mode. Activation is indicated by the
LED in the button.
Press 4 again to deactivate air
recirculation mode.
108Climate control9Warning
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.

Climate control109The preselected temperature is
automatically regulated. In the
automatic mode the fan speed and air
distribution automatically regulate the air flow.
The system can be manually adapted
by use of air distribution and air flow
controls.
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.
Automatic mode Basic setting for maximum comfort: ● Press AUTO.
● Open all air vents.
● Cooling n on.
● Set desired temperature.
Temperature preselection
Temperatures can be set to the
desired value.
For reasons of comfort, change
temperature only in small increments. Turn AUTO knob to adjust.clockwise:warmanticlockwise:cold
Heating will not be fully effective until
the engine has reached normal

When the minimum temperature is
set below 16 ℃, the electronic climate
control system runs at maximum
cooling. LO appears in the display.
If the maximum temperature is set above 32 ℃, the electronic climate
control system runs at maximum
heating. HI appears in the display.
Note
If A/C is switched on, reducing the
set cabin temperature can cause the engine to restart from an Autostop or
inhibit an Autostop.

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.

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.
ServiceFor optimal cooling performance, it is
recommended 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
118Driving and operating● the self-cleaning function of thediesel particle filter is not active
● the vehicle has moved since the last Autostop
● the brake vacuum is sufficient ● the windscreen wipers are not operating at fast speed
● reverse gear is not selected
● heated rear window is not operating
Ambient temperature near to the
freezing point can inhibit an Autostop.
For manual transmission automated
vehicles, an Autostop may be
inhibited until a speed of approx.
10 km/h is reached.
Immediately after motorway driving
an Autostop may be inhibited.

Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.Restarting the engine
Manual transmission
The selector lever must be in neutral
to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the
brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during the restart may be noticeable.
Restarting the engine with the key When one of the following conditionsoccurs during an Autostop, the
engine will need to be restarted
manually using the key.
● the driver's seat belt is unfastened and the driver's door
is opened
● three minutes have elapsed since the engine was switched offIn this event, control indicator ^
flashes in the Driver Information
Centre in conjunction with a warning
chime. Depending on version, a
corresponding message may also be
displayed in the Driver Information
Centre 3 90.
Fault
If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 89.
Depending on version, 9 will
illuminate as an alternative if control
indicator Æ is not present. A
corresponding warning message,
e.g. Start&Stop unavailable , may also
be displayed in the Driver Information
Centre 3 90.
Generic warning 9 3 81.
Seek the assistance of a workshop.
Driving and operating119Parking9Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear before switching off
the ignition. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before switching off the ignition. Turn the front wheels towardsthe kerb.
● Close the windows.
● Turn the ignition key to position
0 and remove it from the
ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
● Lock the vehicle 3 24.
● Activate the anti-theft locking system 3 29.
● The engine cooling fans may run
after the engine has been
switched off 3 142.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Note
In the event of an accident with
airbag deployment, the engine is
switched off automatically if the
vehicle comes to a standstill within a
certain time.
