E 300 (example)
X
Pull oil dipstick :out of the oil dipstick
tube.
X Wipe off oil dipstick :.
X Insert oil dipstick :into the oil dipstick
tube to the stop, and take it out again.
The oil level is correct if the level is between
the minimum mark =and maximum
mark ;.
X Top up the oil if necessary.
Topping up the engine oil 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 otherwise be
damaging the environment. Cap (example)
X
Turn cap :anti-clockwise and remove.
X Top up with the amount of oil required
(Y page 336). i
The difference in quantity between the
minimum mark and maximum mark is
approximately 2 litres.
i On vehicles with a 4-cylinder petrol
engine and vehicles with an 8-cylinder pet-
rol engine, the difference between the MIN
mark and the MAX mark is approximately
1.5 litres.
! Do not add too much oil. If too much oil
is added and the oil level is above the max-
imum mark on the dipstick, the engine or
catalytic converter could be damaged.
Have excess oil siphoned off.
X Replace cap :on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
For further information on engine oil, see
(Y page 336). Coolant
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X Turn the key to position 2(Y page 75) in
the ignition lock.
X Check the coolant temperature gauge in
the instrument cluster. G
Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †. Otherwise, you
could be scalded if hot coolant escapes. Engine compartment

The coolant expansion tank is located in the
engine compartment on the right when
viewed in the direction of travel. X
Slowly turn cap :half a turn anti-clock-
wise and allow excess pressure to escape.
X Turn cap :further anti-clockwise and
remove it.
There is sufficient coolant in expansion
tank ;if the coolant is level with marker
bar =in the filler neck when cold or
approximately 1.5 cm higher when hot.
X If necessary, top up with coolant which has
been tested and approved by Mercedes-
Benz.
X Replace cap :and tighten all the way to
the stop.
For further information on coolant, see
(Y page 338). Windscreen washer system/head-
lamp cleaning system*
The washer fluid reservoir for the windscreen
washer system and headlamp cleaning sys-
tem* is located in the engine compartment on the left-hand side when viewed in the
direction of travel. i
Add windscreen washer concentrate to
the washer fluid all year round. G
Risk of fire
Washer fluid concentrate is highly flammable.
Fire, naked flames and smoking are prohibi-
ted when washer fluid concentrate is being
handled.
! Only use washer fluid concentrate which
is suitable for plastic lenses. Unsuitable
washer fluid concentrate could damage the
plastic lenses of the headlamps.
X Mix the windscreen washer fluid in a con-
tainer beforehand.
X At temperatures above freezing:
Fill the washer fluid reservoir with a mix of
water and windscreen washer concentrate
(e.g. MB SummerFit).
X At temperatures below freezing:
Fill the washer fluid reservoir with a mix of
water, antifreeze additive and windscreen
washer concentrate (e.g. MB WinterFit).
Adapt the mixing ratio to the outside tem-
peratures.
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. 222

misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine control unit.
X
Only depress the accelerator pedal slightly.

workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture gauge shows a
value above 120 †.
