Adding engine oil H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts. Example: engine oil cap X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 – 2 litres.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
For further information on engine oil, see
(Y page 355).
X Replace cap :on the filler neck and

in the "Mercedes-Benz Service24h" section
of the Service Booklet. Care
Notes on care
Regular care of your vehicle is a condition 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. a ring 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 up 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 a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. Care of the exterior
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an auto-
matic car wash.
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.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
! Make sure that: 306

when cleaning. This could lead to irrepara-
ble damage to the display.
Cleaning the plastic trim G
WARNING
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult plastic
parts may break away and be thrown around
the interior when an airbag is deployed, which
may result in severe injuries.
! 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. 310

in the spare wheel well. In this case, you
will have to remove the stowage tray from
the spare wheel well and stow it securely
in the boot.
i When you are driving with the emergency
spare wheel fitted, the tyre pressure loss
warning system cannot function reliably.
Only restart the tyre pressure loss warning
system when the defective wheel has been
replaced with a new wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction display. 324
