Notes on the oil level Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 1000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds.
Checking the oil level using the oil dip-
stick
Depending on the engine, the oil dipstick may
be installed at a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature. Example: vehicles with a petrol engine302

Example: vehicles with a diesel engine
X
Pull oil dipstick :outoft he oil dipstick
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
The oil level is correct if the level is between
MIN mark =and MAX mark ;.
X Top up the oil if necessary.
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
tighten clockwise.
Ensure that the cap locks into place
securely. Checking and adding other service
products
Checking the coolant level 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 137) in
the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 137).
X Check the coolant temperature display in
the instrument cluster. G
WARNING
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
