WARNING
If you connect equipment to the on-board
diagnostics connection, it can affect the operation of the vehicle systems. This can
impair the operating safety of your vehicle
while driving. There is a risk of an accident.
Do not connect any equipment to the on-
board diagnostics connection.
G
WARNING
Loose equipment or equipment cables which
are connected to the on-board diagnostics
connection can obstruct the area around the
pedals. The equipment or the cables could
come between the pedals in the event of
sudden braking or acceleration. This may
affect the function of the pedals. There is a
risk of an accident.
Do not attach any equipment or cables in the
driver's footwell.
! If the engine is switched off and
equipment on the diagnostics connection
is used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to
emissions monitoring information being
reset. This may lead to the vehicle failing to
meet the requirements of the next emissions
test during the main inspection. Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.
Observe the notes in the Maintenance
Booklet.

MaintenanceMaintenance and care

Aq
ualified specialist workshop, e.g. an
authorized Mercedes-Ben zCenter, will reset
the ASSYST PLUS service interval display
after the service work has been carried out.
You can obtain further information, e.g.
regarding service work, from an authorized
Mercedes-Benz Center or directly from
Mercedes-Benz.
Special service requirements
Arduous operating conditions or increased
loads on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous
conditions include regular city driving with
frequent intermediate stops and use in
mountainous terrain or on poor road
surfaces.
For example, if the vehicle is used under
arduous operating conditions, have air filters,
engine oil and oil filters changed frequently
and chec kthe wheels often.F urther
information can be obtaine dataqualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain further information from any
authorized Mercedes-Benz Center. Care
General notes
G
WARNING
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container .Always open your
vehicle's doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosio nofthe brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents
recommended and approved by Mercedes-
Benz. Exterior care
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, you must drive particularly
carefully after washing the vehicle until the
brakes have dried. Care
265Maintenance and care Z

Battery acid is caustic. Avoid
contact with the skin, eyes or
clothing.
Wea
rsuitable protective clothing,
in particular gloves, an apro nand
a face mask.
Immediately rinse acid splashes
off with clean water. Consult a
doctor if necessary. Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz
recommends tha tyou only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz. These
batteries provide increased impact
protection to prevent vehicle occupants from
suffering acid burns should the battery be
damaged in the event of an accident.
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the
vehicle. In this case, have the battery
disconnected at a qualified specialist
workshop. You can also charge the battery
with a charger recommended by Mercedes-
Benz.C ontact a qualified specialist workshop
for further information.
Have the battery charge level checked more
frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for
a lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked for a long period of time.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz. i
Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conserving battery
power.
i If the power supply has been interrupted,
e.g. if you reconnect the battery, you will
have to:
R set the clock (audio system/COMAND,
see the separate operating instructions).
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 91). Charging the battery
