Vehicle care2079Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the
tyre information label and tyre
pressure chart are valid for cold tyres, which means at 20 °C. The pressure
increases by nearly 10 kPa (0.1 bar)
for a 10 °C temperature increase.
This must be considered when warm
tyres are checked.
Trailer towing
When towing a trailer with a fully laden vehicle, the tyre pressure must
be increased by 20 kPa/0.2 bar
(3.0 psi) and the maximum speed
limited to 100 km/h.
Trailer towing 3 177.
Rear-wheel drive, with twin rear
wheels
When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The tyre pressure monitoring system
sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
Tyre pressure chart 3 252.

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 3 252.
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.

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.

Customer information259This data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is processed only in the vehicle itself,and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others 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.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● 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.
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 withthe 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.

260Customer informationDepending on the equipment level in

● 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 adevice 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 moreinformation, 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.
