102Climate 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.
Stop-start system 3 107.
Air recirculation mode 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.
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 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 control103Fixed 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.
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
Note
Refrigerant R-134a contains
fluorinated greenhouse gases.
Driving and operating109● 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 99.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 105.
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 driver
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 71.
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 vehiclebattery 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.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.

Vehicle care143After having changed defective fuses
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.

The fuse box is located on the driver's
side behind a cover in the instrument
panel.
To open the compartment, compress
the locking tabs, fold cover down and
remove.

Customer information181Depending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
data from the vehicle. The same
applies to warranty work and quality
assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which is read out,
documents the technical condition of
the vehicle or individual components
and assists with fault diagnosis,
compliance with warranty obligations
and quality improvement. This data,
in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the
vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also uses operating data
from vehicles for product recalls. This
data can also be used to check
customer warranty and guarantee
claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed or reset at any time.
Depending on the equipment level in
question, these include
● seat and steering wheel position settings
● chassis and air conditioning settings
● custom settings such as interior lighting
You can input your own data in the
infotainment functions for your
vehicle as part of the selected
features.
Depending on the equipment level in
question, these include
● multimedia data such as music, videos or photos for playback in
an integrated multimedia system
● address book data for use with an
integrated hands-free system or an integrated navigation system
