126Climate controlAir conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:
n:cooling4:air recirculation
Cooling n
Press n 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.
Press n again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is above a
specific level. 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.
Stop-start system 3 137.
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
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.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
● Switch on cooling n.
● Air recirculation system 4 on.
● Press air distribution switch M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.
128Climate controlAutomatic mode AUTOBasic setting for maximum comfort: ● Press AUTO: the air distribution
and fan speed are regulated
automatically.
● Open all air vents.
● Press n to switch on cooling.
● Set the desired temperature.
Temperature preselection
Temperatures can be set to the
desired value.
If the minimum temperature is set, the
climate control system runs at
maximum cooling.
If the maximum temperature is set,
the climate control system runs at maximum heating.
Notice
If the temperature is to be reduced
for climate comfort reasons, an
Autostop may be inhibited or the
engine will restart automatically
when cooling is switched on.
Stop-start system 3 137.The temperature can be adjusted
separately for driver and front
passenger side.
Demisting and defrosting the
windows V
● Press V.
● Temperature and air distribution are set automatically and the fan
runs at high speed.
● Switch on heated rear window Ü.
● To return to previous mode: press V, to return to automatic
mode: press AUTO.
Notice
If V is pressed while the engine is
running, an Autostop will be inhibited
until V is pressed again.
If l is pressed with the fan switched
on and the engine running, an
Autostop will be inhibited until l is
pressed again or until the fan is
switched off.If V is pressed while the engine is
in an Autostop, the engine will restart automatically.
If l is pressed with the fan switched
on while the engine is in an
Autostop, the engine will restart
automatically.
Stop-start system 3 137.
Manual settings Climate control system settings can
be changed by activating the buttons
and rotary knobs as follows.
Changing a setting will deactivate the automatic mode.

The selected fan speed is indicated
with x and a number in the display. If
the fan is switched off, the air
conditioning is also deactivated.

Stop-start system 3 137.
Eco appears in the display when
cooling is deactivated.
Air recirculation mode 4
Press 4 once to activate the
manual 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.
Air conditioning with the engine
not running
When ignition is off, the residual heat
or cooling in the system can be used for climate control in passenger
compartment.
Auxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Climate control131Air 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
Notice
Refrigerant R-134a contains
fluorinated greenhouse gases.
Driving and operating139Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 133.
Vehicle battery discharge protection
To ensure reliable engine restarts, several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or 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 driver
Depress the clutch pedal to restart the
engine.
The engine start is indicated by the needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, - with a message is shown in
the Driver Information Centre.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 engine restart might be
noticeable.
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 the parking brake. Activate the parking
brake without pressing the
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.
