sary service work has been carried out. You
can also obtain further information on main-
tenancew ork, for example.
! If the service interval displayh
as been
reset unintentionally,h ave the setting cor-
rected at aMercedes-Benz Center.
Have service work carried out as described in the Maintenance Booklet. This may oth-
erwise lead to increased wear and damage
to the major assemblies or the vehicle.
Special service requirements
The specified maintenance interval takes only the normal operation of the vehicle into
account. Under arduouso perating conditions
or increased load on the vehicle, mainte-
nance work must be carried out more fre-
quently, for example:
R regularc ity driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long peri-
ods
Under these or similarc onditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduouso perating conditions, the tires must
be checked more often. Further information
can be obtained at aqualified specialist work-
shop, 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 author-
ized Mercedes-Benz Center. Care
General notes
Regular care of your vehicle is acondition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! 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. aring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! 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 corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked. Exterior care

passenger door, the transmission remains
in this position for up to 30 minutes if the
SmartKey is in the ignition, even if the

make sure that it is suitable for the dimen- sion soft he vehicle. In particular, make
sure that:
R there is enough groun dclearance
betwee nthe vehicle underbody and the
guide rails of the automatic car wash.
R the clearance width of the automatic car
wash is sufficient ,particularly the width
of the guide rails.
R you enter the automatic car wash

adjustable high-pressure pre-cleaning. This corresponds with the specification for the
Cabriolet program. In car washes that use
high water pressures, there is arisk that a
small amount of water may leak int othe
vehicle.
! Cabriolet:
