142Driving and operatingDiesel particle filterAutomatic cleaning process
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs between seven and twelve
minutes. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.
System requires manual cleaning
process
Under certain driving conditions, e.g.
driving short distances, the system
cannot clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will beindicated by illumination of % and a
warning message in the Driver Information Centre.
% illuminates along with a warning
message illuminates when diesel
particle filter is full. Start cleaning
process as soon as possible.
% flashes along with a warning
message when diesel particle filter
has reached the maximum filling
level. Start cleaning process
immediately to avoid damage to the
engine.
Activate manual cleaning process To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Diesel particle filter
cleaning is then started.
Cleaning takes place quickest at high
engine speeds and loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is
complete. Keep on driving until self-
cleaning operation is complete.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the need for service or repair by a
workshop.
Cleaning process not possible
If cleaning is not possible for anyreasons, control indicator Z
illuminates and a warning message
appears in the Driver Information
Centre. Engine power may be
reduced. Seek the assistance of a
workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.

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.
All tyre sizes are permitted as winter
tyres 3 232.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
Using winter tyres may result in
decreased dry road traction,
increased road noise and shorter
Vehicle care197Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 226.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 232.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressure.9 Warning
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
The 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
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down
tyre will show a decreased value,
which does not indicate an air leak.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
checks the pressure of all four tyres
once a minute when vehicle speed
exceeds a certain limit.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.
Vehicle care199A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these tyres. Control indicator w
illuminates. For the further three
tyres, the system remains
operational.
The use of commercially-available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being
close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor, replace
valve core and sealing ring. For the
clipped sensor, replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according to tyre information label or
tyre pressure chart 3 232, and select
the appropriate setting in themenu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 97 . This setting is
the reference for the tyre pressure
warnings.
The Tyre load menu only appears
when the vehicle is at a standstill and the parking brake is applied. On
vehicles with automatic transmission
the selector lever must be in P.

Data storage modules in the
vehicle
A large number of electronic
components of your vehicle contain
data storage modules temporarily or
permanently storing technical data
about the condition of the vehicle,
events and errors. In general, this
technical information documents the
condition of parts, modules, systems
or the environment:
● Operating conditions of system components (e.g. filling levels)
● Status messages of the vehicle and its single components (e.g.
number of wheel revolutions /
rotational speed, deceleration,
lateral acceleration)
● Dysfunctions and defects in important system components● Vehicle reactions in particular driving situations (e.g. inflation ofan airbag, activation of the
stability regulation system)
● Environmental conditions (e.g. temperature)
These data are exclusively technical
and help identifying and correcting
errors as well as optimizing vehicle
functions.
Motion profiles indicating travelled
routes cannot be created with these
data.
If services are used (e.g. repair
works, service processes, warranty
cases, quality assurance),
employees of the service network
(manufacturer included) are able to
read out this technical information
from the event and error data storage
modules applying special diagnostic
devices. If required, you will receive
further information at these
workshops. After an error has been
corrected, the data are deleted from
the error storage module or they are
constantly overwritten.
