Depending on the operating conditions of the
vehicle, the remaining time or distance until the
next service due date is displayed.
The letter A
orB, possibly in connection with a
number or another letter, indicates the type of
service. A
stands for a minor service and Bfor a
major service.
You can obtain further information from an
authorized Mercedes-Benz Center.
The ASSYST PLUS service interval display does
not take into account any periods of time during
which the battery is disconnected.
Maintaining the time-dependent service sched-
ule:
XNote down the service due date displayed in
the multifunction display before disconnect-
ing the battery.
or
XAfter reconnecting the battery, subtract the
battery disconnection periods from the ser-
vice date shown on the display.

Information about Service
Resetting the ASSYST PLUS service
interval display
!If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
Have service work carried out as described in
the Maintenance Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
A qualified specialist workshop, e.g. an author-
ized Mercedes-Benz Center, will reset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
Special service requirements
The specified maintenance interval takes only
the normal operation of the vehicle into
account. Under arduous operating conditions or
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example:
RRegular city driving with frequent intermedi-
ate stops
RIf the vehicle is primarily used to travel short
distances
RUse in mountainous terrain or on poor road
surfaces
RIf the engine is often left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engine oil 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 a qualified 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.

You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an auto
matic car wash, wipe off wax
from the windshield and the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each country.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with a gen-
tle jet of water.
XDo not point the water jet directly towards the
air inlet.
XUse plenty of water and rinse out the sponge
frequently.
XRinse the vehicle with clean water and dry
thoroughly with a chamois.
XDo not let the cleaning agent dry on the paint- work.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the equip-
ment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
Rtires
Rdoor gaps, roof gaps, joints, etc.
Relectrical components
Rbattery
Rplug-type couplings
Rlights
Rseals
Rtrim
Rventilation slots
Damaged seals or electrical components can
lead to leaks or failures.
!Vehicles with decorative foil: parts of your
vehicle are covered with decorative foil. Main-
tain a distance of at least 27.5 in (70 cm)

Cleaning genuine wood and trim ele-
ments
!Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes
or waxes. There is otherwise a risk of damag- ing the surface.
!Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning
the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center.
XWipe the wooden trim and trim pieces with a
damp, lint-free cloth, e.g. a microfiber cloth.
XTrim elements with piano black finish:
wipe with a soft, damp cotton cloth. Use clean
water.
XHeavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
Note that regular care is essential to ensure that
the appearance and comfort of the covers is
retained over time.
Genuine leather seat covers
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully with a damp cloth and then wipe the covers
down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes- Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
Rclean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergen
t (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
Rclean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
XUse clean, lukewarm water and soap solution.

lowin g tasks:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boilingpoin t
If the coolant has antifreeze protection downto
-35 ‡ (-37 †), the boilingpoin t of the coolant
during operation is approximately 266 ‡
(130 †).
The antifreeze concentrate /corrosion inh ibitor
concentration inthe engine co oling system
should:
Rbe at least 50 %.This willprotect the engine
co olin g system against freezing downto
approximate ly-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡[-45 †]). Otherwise, heat will not be
dissipated as effectively
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Service Products
