130Climate 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.
Centre air vents
Press the vent to open.
Direct the flow of air by swivelling the vent.
Push vent to close.
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.
Combi
Adjustable air vents may be located in the roof frame. To open, press air
vent. Hold air vent and turn it to the
required position to direct the airflow.

Climate control131Bus
Adjustable air vents may be located inthe roof frame above the seats. Turn
adjuster to increase/decrease airflow
to the appropriate seat.
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.
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 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

134Driving and operatingDriving hints
Driving economically
ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
ActivationPress ECO. Control indicator
illuminates when activated and a corresponding message appears in
the Driver Information Centre 3 103.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press ECO again. Control indicator
extinguishes.
Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there may be a controlled
reduction in power steering assist and
vehicle speed is reduced.Stop-start system 3 137.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Use only floor mats which fit properly and are fixed by the retainers on the
driver's side.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.
Steering If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.
