Topping up the windscreen washer sys-
tem/headlamp cleaning system G
WARNING
Windscreen washer concentrate is highly
flammable. If it comes into contact with hot
engine components or the exhaust system it
could ignite. There is a risk of fire and injury.
Make sure that no windscreen washer con-
centrate is spilled next to the filler neck. Example
X To open: pull cap:upwards by the tab.
X Top up with the premixed washer fluid.
X To close: press cap :onto the filler neck
until it engages.
The washer fluid reservoir is used for both the
windscreen washer system and the headlamp cleaning system.
The recommended minimum amount when
topping up is 1 litre. If the water level drops
below this, a message appears in the multi-
function display prompting you to refill the
washer fluid (Y page 256).
Further information on windscreen washer
fluid/antifreeze (Y page 345). Service
ASSYST PLUS
Service messages The ASSYST PLUS service interval display
informs you of the next service due date. Information on the type of service and service
intervals (see separate Service Booklet).
You can obtain further information from any
Mercedes-Benz Service Centre.
i The ASSYST PLUS service interval display
does not show any information on the
engine oil level. Observe the notes on the
engine oil level (Y page 286).
The multifunction display shows a service
message for a few seconds, e.g.:
R Next service A in .. days
Next service A in .. days
R Service A due Service A due
R Service A overdue by .. days
Service A overdue by .. days
Depending on the operating conditions of the vehicle, the remaining time or distance until
the next service due date is displayed.
The letter indicates which service is due. A
A
stands for a minor service and B Bfor a major
service. A number or another letter may be
displayed after the letter. This figure indicates any necessary additional maintenance work
to be performed.
If you notify a qualified specialist workshop ofthis display, you will receive a statement on
the associated costs.
The ASSYST PLUS service interval display
does not take into account any periods of
time during which the battery is disconnec-
ted.
Maintaining the time-dependent service
schedule:
X Note down the service due date displayed
in the multifunction display before discon-
necting the battery.
or
X After reconnecting the battery, subtract
the battery disconnection periods from the
service date shown on the display.

Mercedes-Benz Service Centre. Interior care
Cleaning the display !
For cleaning, do not use any of the fol-
lowing:
R alcohol-based thinner or petrol
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do not put pressure on the display surface
when cleaning. This could lead to irrepara-
ble damage to the display.
X Before cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display surface using a commer-
cially available microfibre cloth and
TFT/LCD display cleaner.
X Dry the display surface using a dry micro-
fibre cloth. Cleaning the plastic trim G
WARNING
Care products and cleaning agents containing solvents can cause surfaces in the cockpit to
become porous. This could result in plastic
parts breaking away when the airbags are
deployed. There is a danger of injury.
Do not use care products and cleaning agents containing solvents to clean the cockpit.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You could otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come in contact with the
plastic trim. This maintains the high-quality look of the surfaces.
X Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfibre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface may change colour tempora-
rily. Wait until the surface is dry again.
Cleaning the steering wheel and gear or selector lever X
Thoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning wooden trim and trim ele-
ments !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of damaging the surface. Care
295Maintenance and care Z

X
Wipe the wooden trim and trim elements
with a damp, lint-free cloth, e.g. a microfi-
bre cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
Cleaning the seat covers General notes
! Do not use microfibre cloths to clean gen-
uine leather, artificial leather or Alcantara®
covers. If used often, these can damage the cover.
i Note that regular care is essential to
make sure that the appearance and com-
fort of the covers are retained over time.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R Differences in the texture
R Signs of stretching and marking
R Slight nuances of colour
These are characteristics of leather and not
material defects.
! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a quali- fied specialist workshop. Seat covers of other materials
! Observe the following when cleaning:
R Clean artificial leather covers with a cloth
moistened with a solution containing 1% detergent (e.g. washing-up liquid).
R Clean cloth covers with a microfibre
cloth moistened with a solution contain-
ing 1% detergent (e.g. washing-up liquid).
Rub carefully, and always wipe entire
seat sections 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.
R Clean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts G
WARNING
Seat belts may be severely weakened if
bleached or coloured. This may lead to the
seat belts, for example, tearing or failing in an accident. There is an increased risk of injury,
possibly even fatal.
Never bleach or colour seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts at
temperatures above 80 † or in direct sun-
light.
X Use clean, lukewarm water and soap solu-
tion.
Cleaning the roof lining and carpets X
Roof lining: if it is very dirty, use a soft
brush or a cleaning agent recommended
and approved by Mercedes-Benz.
X Carpets: use the carpet and textile clean-
ing agents recommended and approved by Mercedes-Benz. 296

Additives
!
Do not use any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications are to be
used. The low-temperature properties of engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regular oil
changes using an approved engine oil with the
appropriate SAE classification. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
When handling brake fluid, observe the
important safety notes on service products
(Y page 338).
The brake fluid change intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at:
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at
a qualified specialist workshop. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you top up
the antifreeze. Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly 344
