Cover
X Unscrew cap 1 and remove it.
X Top up by the amount of oil required.
! Do not add too much oil. If too much oil
is added, there is a risk of damage to the
engine or the catalytic converter.
X Screw cap 1 onto the filler neck.
H Environmental note
When topping up the oil, take care not to
spill any. Oil must not be allowed to escape
into the soil or waterways. You would oth-
erwise be damaging the environment.
Coolant
G Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. The coolant temperature
gauge must display less than 70°C. You
could otherwise be scalded by escaping hot
coolant.
Coolant consists of water and antifreeze/cor-
rosion inhibitor. Only check the coolant level
when the vehicle is on a level surface and the
engine has cooled down. Checking the coolant levelThe expansion tank is located in the engine
compartment on the left when viewed in the
direction of travel.

X Slowly turn cap 1 by half a turn anti-clock-
wise to allow excess pressure to escape.
X Turn cap 1 further anti-clockwise and
remove it.
There is sufficient coolant in expansion
tank 2 if the coolant is level with marker
bar 3 in the filler neck when cold or
approximately 1.5 cm higher when hot.

X Replace cap 1 and tighten all the way to
the stop.
You will find further information about coolant
in the "Technical data" section
(Y page 316). Windscreen washer system/head-
lamp cleaning system*
The washer fluid reservoir is located in the
engine compartment on the right when
viewed in the direction of travel. The head-
lamp cleaning system* is also supplied from
the washer fluid reservoir.1 Cover X
Add windscreen washer concentrate to the
washer fluid all year round.
G Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled.
Use
R a windscreen washer fluid additive
such as MB Summerwash to prevent
smearing (for temperatures above freez-
ing).
R a windscreen washer fluid additive with
antifreeze properties such as MB Winter-
wash (if there is a risk of frost).
X Mix the windscreen washer fluid in a con-
tainer beforehand. Adapt the mixing ratio
to the outside temperatures.
! Only use windscreen washer fluid which
is suitable for plastic lamp lenses. Unsuit-
able windscreen washer fluid could dam-
age the plastic lamp lenses of the head-
lamps. X
To open: pull cap 1 upwards by the tab.
X To close: press cap 1 onto the filler neck
until it clicks into place.
