Climate control141Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling may inhibit
Autostops.

Air recirculation system nPress n to activate air recirculation
mode, LED is indicated.
Press n 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 from inside.
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 l.

Auxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.Air vents
Adjustable air vents At least one air vent must be open
while cooling is on.
To open the vent, turn the adjuster
wheel towards the bigger W symbol.
Adjust the air amount at the vent
outlet by turning the adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel towards the smaller W symbol.
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.

Climate control149Maintenance
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.
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 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

158Driving and operatingConditions 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 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 engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The brake vacuum is sufficient.
● Between the last restart and a new Autostop must be about10 seconds.● The self-cleaning function of the exhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
The stop-start system will be
deactivated on inclines of 12% or
more.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 140.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 151.
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 e.g. auxiliary electric heater
or heated rear window are disabled orswitched to a power saving mode.
The fan speed of the climate control
system is reduced to save power.
Restart of the engine by the driverVehicles with manual transmission
Depending on the engine, two
versions of a restart are available.
See engine data to identify the engine
identifier code for your vehicle
3 278.
Conventional restart
Depress the clutch pedal to restart the
engine. For engines with late restart,
this is only possible without
depressing the brake pedal.
Late restart ● Depress the brake pedal.
● Depress the clutch pedal.
● Select first gear.
● Release the brake pedal to restart the engine.Vehicles with automatic transmission:Release the brake pedal or move
selector lever out of D into N or P to
restart the engine.
