Climate control127Air vent in the glovebox
The air vent can be opened or closedby turning.
At least two air vents must be open
while cooling is on.
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.
Cabin air filter
Change filter regulary for maximum
effect.
More frequent passenger
compartment air filter replacement
may be needed, if you drive in areas
with heavy traffic, poor air quality,
Page 130 of 259
128Climate controlareas with high dust levels or which
are sensitive to environmental
allergens.
Passenger compartment air filter
replacement may also be needed if
there is reduced air flow, windows
fogging up, or odors.
Your dealer can help to determine
when it is the right time to replace the
filter.
Air conditioning regularoperation
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 the
outside temperature is too low.
Service For optimal cooling performance, it is
recommended 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
● cabin air filter check

136Driving and operatingIndication
An Autostop is indicated by control
indicator D.
During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated.
● The driver's door is closed or 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 temperatureis 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 brake vacuum is sufficient.
● The self-cleaning function of the diesel particle filter is not active.
Otherwise an Autostop will be
inhibited.
Notice
The Autostop may be inhibited for
several hours after a battery
replacement or reconnection.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 118.
If an autostop is temporarily not
available, D flashes green 3 92.
Immediately after driving at a higher
speed an Autostop may be inhibited.
New vehicle running-in 3 130.Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to save power.
Restart of the engine by the driver
Vehicles with manual transmissionConventional restart
All engines have conventional restart.
Depress the clutch pedal without
depressing the brake pedal to restart the engine.
On engines with late restart a
conventional restart is only possible
without depressed brake pedal.

Driving and operating137Restart of the engine by the stop-start system
The selector lever must be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically by the stop-start system:
● The stop-start system is manually deactivated.
● The driver's seat belt is unfastened or the driver's door is
opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressing the 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 or set the selector
lever to position P before
removing the ignition key or
switching off ignition on
vehicles with power button. On an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
button. Turn the steering wheel until the steering wheel lock is
felt to engage.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 187.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low
Page 140 of 259

138Driving and operatingload or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
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.
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
Automatic cleaning process
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases.
The start of saturation of the particle
filter is indicated by the temporary illumination of % or H ,
accompanied by a message in the
Driver Information Centre.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 40 mph
until the control indicator
extinguishes.
Notice
On a new vehicle, the first particle
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or H stays on, accompanied
by an audible signal and a message,
this indicates that the particle filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.

186Vehicle 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 or set selector lever
to P. 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
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 recovery
