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
Risk of fire and injury
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
Turn cap : anti-clockwise and remove it.
X
Top up with the amount of oil required.
X
Observe the specifications in the on-board
computer when doing so or fill carefully to the
maximum mark on the oil dipstick.
Engine compartment
i
The difference between the minimum
mark and the maximum mark on the oil
dipstick is approximately 1.2 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.
