duration 30 minutes, or cut-off
immediately, using the button on the
instrument panel. The LED in the
button confirms operation.
Battery replacement
Replace the battery when the range
of the remote control is reduced or
when the battery charge symbol
flashes.
Open the cover and replace the
battery (Type A: CR 2430, Type B:
2CR 11108, or equivalent), ensuring
the new battery is correctly installed
with the positive ( <) side facing the
positive terminals. Replace the cover
securely.
Dispose of old batteries in
accordance with environmental
regulations.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

Climate control125Air 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.
126Climate controlBus
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

Driving and operating133An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained. Brake assist, however, is
not available 3 151.
Note
If you exit the vehicle while the
engine is in an Autostop, a warning
chime will sound as a reminder that
the engine is on standby and has not been switched off.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● 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 self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control system may also inhibit an Autostop.See "Climate control" chapter for
further information 3 112.
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 3 130.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driver
Depress the clutch pedal to restart the
engine.
If the selector lever has been shifted
out of neutral (manual transmission)
or N (manual transmission
automated) or other conditions are
not met, start using the ignition key.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted.
If the selector lever is shifted out of
neutral (manual transmission) or N
(manual transmission automated) before depressing the clutch first, a
restart will not take place.
134Driving and operatingRestart of the engine by the stop-
start system
The selector lever must be in neutral(manual transmission) or N (manual
transmission automated) 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 bonnet is opened
● the driver's seat belt is unfastened and the driver's door
is opened
● 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 systemrequests an engine start
● the predetermined timing has been exceeded
If 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 interrupted during the restart.
Warning chimes 3 99.
Fault
If control indicator Ï illuminates
yellow, there is a fault in the stop-start system 3 96. A corresponding
message also appears in the Driver
Information Centre 3 98. Seek the
assistance of a workshop.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 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. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards the kerb.
