not an indicator for a low engine oil lev­

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
l!I 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
1!1-By then, your engine
may already have suffered serious dam­
age.
