Was the oil level near full on the dip stick. From the manual:

if the low engine oil
level warning lamp comes on, a malfunction in the
engine oil level system is indicated. A conveniently
located dipstick allows manual checking of the oil level.
If no leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
