ENGINE OIL
Checking engine oil
Check the oil level a few minutes (about
5) after the engine has stopped, with the
car parked on level ground.
Remove the dipstick Aand clean it, put
it back in completely, remove it and check
that the level is within the MIN and MAX
marks on the dipstick. The gap between
the MIN and MAX marks corresponds to
about one litre of oil.
Topping up engine oil
If the oil level is near or even below the
MIN mark, add oil through the filler neck
B, until reaching the MAX mark.
Oil level shall never exceed the MAX
mark.IMPORTANT If a routine check reveals
that the oil level is above the MAX mark,
contact Fiat Dealership to have the cor-
rect level restored.
IMPORTANT After adding or changing
the oil, let the engine turn over for a few
seconds and wait a few minutes after turn-
ing it off before you check the level.
When the engine is hot, take
care when working inside the
engine compartment to avoid burns.
Remember that when the engine is
hot, fan may cut in: danger of injury.
Scarves, ties and other loose cloth-
ing might be pulled by moving parts.
