156Climate controlMaintenanceAir 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 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

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
3 289.
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
All petrol engines and the diesel
engines B16DTU and B16DTR have
late restart in addition to conventional
restart. Late restart is only active on
inclines up to 5%.
● Depress the brake pedal.
● Depress the clutch pedal.● Select first gear.
● Release the brake pedal to restart the engine.Vehicles with automatic transmission
or manual transmission automated:
Release the brake pedal or move
selector lever out of D into N or P to
restart the engine.
Restart of the engine by the stop-
start system
On vehicles with manual transmission
which are in a conventional Autostop,
the selector lever must be in neutral
to enable an automatic restart.
On vehicles with manual transmission
which are in an early Autostop, an
automatic restart is possible, when
not in neutral if the brake pedal and
the clutch pedal are depressed.
On vehicles with automatic
transmission or manual transmission
automated, the selector lever must be
in D to enable an automatic restart.
The engine will be restarted
automatically by the stop-start
system, if one of the following
conditions occurs during an Autostop:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and / or the driver'sdoor 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 desired compartment temperature does not match the
actual temperature.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.

Customer information307● Faults and defects in importantsystem 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.
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, the operating
data saved can be read together with the vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases 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 has been read
out documents the technical conditionof 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 needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed 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,
● Input destinations,
● Data on the use of online services.
This data for comfort and
infotainment functions can be stored
locally in the vehicle or be kept on a
