Side air vents
Press the vent to open.
Direct the flow of air by swivelling the vent.
Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in the event of
an accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler
The air conditioning system can also keep the contents of the glovebox
cool.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.

Climate control105Air 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 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

Driving and operating109
The engine will be switched off while
the ignition stays on if the required conditions are met.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the brake
performance will be maintained.
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 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 ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an Autostop
■ the brake vacuum is sufficient
■ the vehicle has moved since the last Autostop
■ the diesel particle filter self- cleaning function is in progress
An Autostop may be less available as
the ambient temperature approaches
freezing point.Certain settings of the climate control system may inhibit an Autostop. See
Climate control chapter for further
information 3 94.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.
New vehicle running-in 3 106.
Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine. If the selector lever has been
shifted out of N or other conditions are
not met, start using the ignition key.
Control indicator Ï will extinguish in
the instrument cluster when the
engine is restarted.

110Driving and operating
If the selector lever is shifted out of
N before depressing the clutch first, a
restart will not take place.
Restart of the engine by the
stop-start system
The selector lever has to be in N 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. Control
indicator Ï will flash green in the
instrument cluster during an
automatic engine restart.
■ The stop-start system is manually deactivated
■ the engine temperature is too low ■ the vehicle battery is discharged
■ the brake vacuum is not sufficient
■ the vehicle starts to move
■ the defrosting function is activated
■ the climate control system requests
an engine start
■ the predetermined timing has been
exceededIf an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
If the Infotainment system is active,
audio sound may briefly be reduced
or broken during restart.
Warning chimes 3 84.
Fault
If control indicator Ï illuminates
yellow, there is a fault in the stop-start system 3 82. Seek the assistance of
a workshop.
Parking ■ 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 or
uphill slopes. Operate the foot
brake at the same time to reduce
operating force.■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ 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 towards the kerb.
■ Lock the vehicle and activate the anti-theft locking and anti-theft
alarm systems.
Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
For further information on the air
suspension system, refer to the
operating instructions supplied.
