(g) 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 levelº on page 329.)
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.In normal conditions, due to engine oil consumption, this light
may come on earlier than the specified service interval of the
scheduled maintenance. This is because the engine oil is
consumed to the low level within the scheduled maintenance
interval and does not indicate a problem. (For detailed
information, see Facts about engine oil consumptionº on page
327.)
NOTICE
Continued engine operation with low engine oil will
damage the engine.

seconds and then flashes for about 12 seconds with the
ignition key turned to the ONº position. If you continue driving

control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.
