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 40.
Heated rear window Ü 3 34.
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 3 114.
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.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.

When the minimum temperature is
set below 16 ℃, the electronic climate

If the maximum temperature is set
above 32 ℃, the electronic climate
control system runs at maximum

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.
Centre air vents, side air vents
Slide knob to the left to open vent.
Direct the flow of air by swivelling the vent.
Slide knob to the right to close vent.
Fixed air vents Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Driving and operating115AutostopIf the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● depress the clutch pedal
● set the lever to neutral
● release the clutch pedal
The engine will be switched off while
the ignition stays on.
An Autostop is indicated when control
indicator ^ flashes in the Driver
Information Centre 3 89.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Caution
The steering assist may be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
Otherwise an Autostop will be
inhibited.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed and the
driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the engine exhaust temperature is not too high, e.g. after driving
with high engine load
● the ambient temperature is not too low
● the climate control system allows
an Autostop
● the self-cleaning function of the diesel 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.
New vehicle running-in 3 112.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Driving and operating117● 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.
Note
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle comes to a standstill within a certain
time.
Engine exhaust9 Danger
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 and may
take up to 25 minutes. Typically it
needs 15 minutes. 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 the cleaning of the filter is required
and if previous driving conditions did
not enable automatic cleaning, it will
be indicated by control indicator %.
Depending on version, a warning
message may also appear in the
Driver Information Centre 3 89.
138Vehicle careCaution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, wellventilated place. Engage first or
reverse gear to prevent the
vehicle from rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and 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
locking 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 plates if necessary.End-of-life vehicle recovery
