Vehicle care291Wheels 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.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Tyres Factory-fitted tyres are matched to
the chassis and offer optimum driving comfort and safety.Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the maximum speed
sticker in the driver's field of view.
Tyre designations
E.g. 215/65 R 16 C 109 R215:tyre width, mm65:cross-section ratio (tyre height
to tyre width), %R:belt type: RadialRF:type: RunFlat16:wheel diameter, inchesC:cargo or commercial use88:load index e.g. 109 is
equivalent to approx. 1030 kgR:speed code letter
Speed code letter:
Q:up to 160 km/hS:up to 180 km/hT:up to 190 km/hH:up to 210 km/hV:up to 240 km/hW:up to 270 km/hChoose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Directional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
The tyre pressure information label
on the driver's door frame indicates the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 317.

310Vehicle careUnderbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen / rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean leather upholstery with clear
water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.

324Customer informationOperating 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.
