about possible vehicle damage. Damage to
your vehicle that arises from culpable contra-
ventions against these instructions are not
covered either by Mercedes-Benz implied
warranty or by the New or Used-Vehicle War-
ranty. QR code for rescue card
The QR code is secured in the fuel filler flap and
on the opposite side on the B-pillar. In the event of an accident, rescue services can use the QR
code to quickly find the appropriate rescue card
for your vehicle. The current rescue card con-
tains, in a compact form, the most important
information about your vehicle, e.g. the routing
of the electric cables.
You can find more information under
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Many of the electronic components in your vehi- cle can store data.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
This includes, for example:
R operating conditions of system components –
for example, fluid levels
R status messages concerning the vehicle and
its individual components – for example, num- ber of wheel revolutions/speed, decelerationin movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important system
components – for example, lights, brakes
R vehicle reactions and operating conditions in
special driving situations – for example, air-
bag deployment, intervention of stability con-
trol systems
R ambient conditions – for example, outside
temperature These data are of an exclusively technical nature
and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory
and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
The information is read out by employees of the
service network (including the manufacturer)
using special diagnostic testers. You can obtain more information there, if required.
After a fault has been rectified, the information
is deleted from the fault memory or is continu-
ally overwritten.
During vehicle operation, certain situations may
arise in which these technical data – in conjunc-
tion with other information and, if applicable,
after consultation with an approved assessor –
may be linked to an individual person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for example, vehicle location in the event of an
emergency. Copyright information

Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resins, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R vigorous rubbing with unsuitable materials
R frequent use of car washes
R washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the purpose of paintwork care. These products
are only suitable for high-gloss surfaces. Their
use on vehicles with matt paintwork leads to
considerable surface damage or, more spe-
cifically, to shiny, spotted areas.
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a clear
matt finish. This will help you to avoid damage to the paintwork due to incorrect treatment.
These notes also apply to light-alloy wheels with
a clear matt finish.
i The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products. Cleaning vehicle parts
Cleaning the wheels G
WARNING
The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced
immediately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up your vehicle for a long period
of time immediately after cleaning, particu-
larly after cleaning the wheel rim with wheel
cleaner. Wheel cleaner may lead to increased corrosion of the brake discs and pads. You
should therefore drive for a few minutes after
cleaning. By heating up the brakes, the brake
discs and pads dry. The vehicle can then be
parked up for a long period of time.
Cleaning the windows G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury.
Always switch off the windscreen wipers and
the ignition before cleaning the windscreen or wiper blades.
! Do not use dry cloths, abrasive cleaning
agents, solvents or solvent-based cleaning
agents to clean the inside of the windows/
windscreen. Do not touch the inside of the
windows/windscreen with hard items such
as an ice scraper or a ring. Otherwise, the
windows/windscreen could be damaged.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals and
pollen may under certain circumstances pre- 240
