Aq ualified specialist workshop, e.g. an author-
ized Mercedes-Ben zC enter, will reset the
ASSYS TP LUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work ,f or example.
Specia ls ervice requirementsThe specified maintenance interval takes only
the normal operation of the vehicle into
account .U nder arduous operating condition so r
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example: R
regular cit yd rivin gw ith frequent intermediate
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 engin eiso ften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eo il and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be
obtained at aq ualified specialist workshop, e.g.

Care
Maintenance and care

Observe the notes in the section on the care and
treatment of matt paintwork ( Y
page 240);
these notes also apply to decorative film.
To clean, use plenty of water and am ild cleaning
agent without additional or abrasive products,
e.g. ac ar shampoo approved by Mercedes-
Benz. X
Remove bird droppings, tree resin or fuel as
soon as possible.
The decorative film may be irreparably dam-
aged. X
Dry vehicles covered with film using as oft,
absorbent cloth after every wash.
Water marks could otherwise form.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit aq ualified specialist workshop.
The cleaning product Paint Cleaner, which has
been approved and recommended by
Mercedes-Benz ,s hould be used when dirt has
penetrated the decorative film surface or the
decorative film has become dull.
The manufacturer can provide you with infor-
mation on special care and cleaning products.
Surfaces covered with film may appea rs hinier
after the decorative film has been removed.
i Have work or repairs on decorative film car-
ried out at aq ualified specialist workshop.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose.

edly .T here is ar isk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis component sr eplaced imme-
diately. ! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for al ong period of
time directly after cleaning, particularl ya fter
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for af ew minutes after cleaning. By
