It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle owner-
ship. You can do this at a Mercedes-Benz Ser-
vice Centre, for example. Correct use
If you remove any warning stickers, you or oth-
ers could fail to recognise certain dangers.
Leave warning stickers in position.
Observe the following information when driving your vehicle:
R the safety notes in this manual
R the vehicle technical data
R traffic rules and regulations
R laws and safety standards pertaining to motor
vehicles Implied warranty
! Follow the instructions in this manual about
the proper operation of your vehicle as well as
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 http://
portal.aftersales.i.daimler.com/public/
content/asportal/en/communication/
informationen_fuer/QRCode.html. 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,
e.g. fluid levels
R status messages concerning the vehicle and
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelerator
pedal position
R malfunctions and defects in important system
components, e.g. lights, brakes
R vehicle reactions and operating conditions in
special driving situations, e.g. airbag deploy-
ment, intervention of stability control sys-
tems
R ambient conditions, e.g. 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. Introduction

X
Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a gen-
tle jet of water.
X Do not point the water jet directly towards the
air inlets.
X Use plenty of water and rinse out the sponge
frequently.
X Rinse the vehicle with clean water and dry
thoroughly with a chamois.
X Do not let the cleaning agent dry on the paint-
work.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
High-pressure cleaning equipment 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.
! Always maintain a distance of at least 30 cm
between the vehicle and the high-pressure
cleaner nozzle. Information about the correct
distance is available from the equipment
manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R electrical components
R battery
R plug connectors
R lamps
R seals
R trim elements
R ventilation slots
Damage to seals or electrical components
can lead to leaks or failures. Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
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 resin, 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. Care
