(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication
Ill requires oil refill or workshop serv­
ice without delay . Do not wait until the
red oil pressure warning. starts to
flash before you respond to the low oil level warning
Ill. By then, your engine
may already have suffered serious dam­
age.
