GAUGES, METERS AND SERVICE REMINDER INDICATORS
(e) 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.

(f) Low Engine Oil Level Warning Light
This light warns that the engine oil level is too low. Add
oil as soon as possible. (For instructions, see "Checking
the engine oil level" on page 410.)
While driving on steep inclines or rough roads which
causes the vehicle to substantially sway or on curves,
this light may come on due to the movement of engine
oil in the engine.
NOTICE
Continued engine operation with low engine oil
will damage the engine.

c. There is a problem somewhere in your engine or
automatic transmission electrical system.
If it comes on while you are driving in case "c.", have your

as possible.
