208Vehicle careLow tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 104 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 233.
After inflating, some driving may be
required to update the tyre pressure
values in the system. During this time
w may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise w flashes for
several seconds then illuminates
continuously together with control
indicator A 3 101 and a
corresponding message appears in
the Driver Information Centre.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. For the further three wheels, the tyre pressure monitoring
system remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.

Vehicle messages 3 107.Puncture
A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 102 and a corresponding message
appears in the Driver Information
Centre. Stop vehicle and switch off
engine.
Tyre pressure 3 233.

Service and maintenance227International service intervalsAlbania, Bosnia-Herzegovina,
Kosovo, Macedonia, Montenegro,
Serbia, Romania, Bulgaria, Moldova,
Cyprus:
Maintenance of your vehicle is
required every 30,000 km or after
two years, whichever occurs first,
unless otherwise indicated by the
service display.
Turkey, Morocco:
Maintenance of your vehicle is
required every 20,000 km or after one year, whichever occurs first,
unless otherwise indicated by the
service display.
Russia, Ukraine, Belarus,
Kazakhstan, Malta:
Maintenance of your vehicle is
required every 15,000 km or after
one year, whichever occurs first,
unless otherwise indicated by the
service display.Algeria, Tunisia:
Maintenance of your vehicle is
required every 10,000 km or after
one year, whichever occurs first,
unless otherwise indicated by the service display.
Severe operating conditions exist if
one or more of the following
circumstances occur frequently: Cold
starting, stop and go operation, 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.
Confirmations Confirmation of service is recorded inthe Service and warranty booklet.
The date and mileage is completed
with the stamp and signature of the
servicing workshop.Make sure that the Service and
warranty booklet is completed
correctly as continuous proof of
service is essential if any warranty or
goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service display The service interval is based on
several parameters depending on
usage.
The service display, located in the
Driver Information Centre, indicates
when the next service is due. Seek
the assistance of a workshop.

Engine oil lever monitor 3 96.

Customer information239Operating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, e.g.: ● 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, not
stored for longer than an operational
cycle, and only processed on board
the vehicle itself. Control units often
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
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. 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 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.

240Customer informationComfort 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 stick
or 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.
Integration allows selected
smartphone apps to be used, such as
navigation or music playback. No
further integration is possible
between smartphone and vehicle, in particular active access to vehicle
data. The nature of further data
processing is determined by the
provider of the app used. Whether
you can define settings, and if so
which ones, is dependent on the app
in question and your smartphone's
operating system.
