the climate control system runs at maximum heating.
Recommended temperature is 22 °C .
Notice
If A/C is switched on, reducing the
set cabin temperature can cause the engine to restart from an Autostop or
inhibit an Autostop.

Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
Driving with recirculation mode for
a prolonged period of time can
make you sleepy. Periodically turn to the outside air mode for fresh
air.
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. 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 V.
Manual settings Climate control system settings can
be changed by activating the buttons
and rotary knobs as follows.
Changing a setting will deactivate
Automatic mode.

to the desired speed. The selected
fan speed is indicated by the number
of segments in the display. If the fan
is switched off the air conditioning is also deactivated.

Cooling A/C
Press A/C to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running and climate control fan is switched on.
100Climate controlPress 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 might inhibit
Autostops.

In operation without cooling, the
air humidity increases, so the

Maximum cooling Briefly open the windows so that hotair can disperse quickly.
● Switch on cooling A/C.
● Switch on Air recirculation system 4.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Set air distribution control to M.
● Open all vents.
Air vents
Adjustable air vents
At least one air vent must be open
while the cooling is on.
Direct the flow of air by tilting and
swivelling the slats.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Climate control101Fixed air ventsAdditional 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.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
The filter should be replaced as part
of routine scheduled maintenance.Caution
More frequent maintenance of the passenger compartment air filter is
required if the driving
circumstances are dusty roads, air pollution areas, and frequent
unpaved roads.
The filter efficiency is decreased
and the bronchus is badly
affected.
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.
102Climate controlService
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
Driving and operating107Deactivation
Deactivate the stop-start system
manually by pressing Ï. The
deactivation is indicated when the
LED in the button extinguishes.
Autostop
Vehicles with manual transmission
If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Set the lever in neutral.
● Release the clutch pedal.The engine will be switched off while
the ignition stays on.Vehicles with manual transmission
automated
If the vehicle is at a standstill with the brake pedal depressed, Autostop is
activated automatically.
The engine will be switched off while
the ignition stays on.
The stop-start system will be disabled
on inclines of 15% or more.
Indication
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
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 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 climate control system allows an Autostop.
108Driving and operating● The brake vacuum is sufficient.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
"Climate control" chapter for further
information 3 97.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 104.
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., the rear window
heating, are disabled or switched into 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
Depress the clutch pedal to restart the
engine.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in
the Driver Information Centre.
Control indicator - 3 69.Vehicles with manual transmission
automated
Release the brake pedal or move
selector lever out of D to restart the
engine.
Restart 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 bonnet is opened.
● The driver's seat belt is unfastened and 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 vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
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.
