Climate control119Air vent in the glovebox
The air vent can be opened or closedby turning.
Fixed air vents Additional 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.
Cabin air filter
Change filter regulary for maximum
effect.
More frequent passenger
compartment air filter replacement
may be needed, if you drive in areas
with heavy traffic, poor air quality,
areas with high dust levels or which
are sensitive to environmental
allergens.
Passenger compartment air filter
replacement may also be needed if
there is reduced air flow, windows
fogging up, or odors.
Your dealer can help to determine
when it is the right time to replace the
filter.
Air conditioning regularoperation
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 3
years after initial vehicle registration, including:

Vehicle care195Vehicles without spare wheel
The screwdriver and the towing eye
are located in a box below the floor
cover in the load compartment.
Tyre repair kit 3 199.
Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and shouldtherefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
All tyre sizes are permitted as winter

Choose a tyre appropriate for the
maximum speed of this vehicle. Refer to the EEC Certificate of Conformity
provided with the vehicle or other
national registration documents.
Optional equipment could reduce the
maximum speed of the vehicle.

Service and maintenance215General information
Service information
In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for your vehicle is available
at the workshop.
Severe operating conditions exist if one or more of the following
circumstances occur frequently: Cold starting, stop and go operation, e.g.
for taxis and police vehicles, trailer
operation, mountain driving, driving
on poor and sandy road surfaces,
increased air pollution, presence of
airborne sand and high dust content,
driving at high altitude and large
variations of temperature.
Under these severe operating
conditions, certain service work may
be required more frequently than the
regular service interval indicated inthe service display. Contact a
workshop for customised service
schedules.
Service display 3 80.

Customer information241Legal requirements for
information disclosure
Insofar as regulatory requirements
exist, manufacturers are strictly
bound to release data stored by the
manufacturer in individual cases to
the extent requested following a
request by state bodies (e.g. during
criminal investigations).
Government agencies are also
authorised, in the context of
applicable law, to read data in
individual cases from vehicles
themselves. Thus information that
may help with the investigation
resolution can possibly be read from
the airbag control unit in the event of
an accident.
Operating data in the vehicle Control units process data for
operation of the vehicle.This data includes, for example:
● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate, "seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient and is
not stored for longer than an
operational cycle, and only processed
on board the vehicle itself. Often
control units include data storage
(including the vehicle key). This is
used to allow information to be
documented temporarily or
permanently on vehicle condition,
component stress, maintenance
requirements and technical events
and errors.
Depending on technical equipment
levels, 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. triggering
of 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 where 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 read documents the
technical condition of the vehicle or

242Customer informationindividual 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
● 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
device that you have connected to the
vehicle ( e.g. a smartphone, USB stickor MP3 player). Data that you have
input yourself can be deleted at any
time.
This data can only be transmitted out
of the vehicle at your request,
particularly when using online
services in accordance with the
settings selected by you.
Smartphone integration, e.g.
Android Auto or Apple CarPlay
If your vehicle is equipped
accordingly, you can connect your
smartphone or another mobile device to the vehicle so that you can control
it via the controls integrated in the
vehicle. The smartphone image and
sound can be output via the
multimedia system in this case. At the
same time, specific information is
transmitted to your smartphone.
Depending on the type of integration, this includes data such as position
data, day / night mode and other
general vehicle information. For more
information, please see the operating
instructions for the vehicle /
infotainment system.
