(f) Low Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.
The light may occasionally flicker when the engine is idling
or it may come on briefly after a hard stop. There is no cause
for concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low.
It is not designed to indicate low oil level, and the oil level
must be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on – even
for one block. It may ruin the engine.
