D The light comes on while driving. (f) Low Engine 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.

Look first at the engine drive belt. D If it is loose or broken, the generator will not charge the battery properly. D If the belt is O.K., there is a problem somewhere in the charging system. The engine ignition will continue to operate, however, until the battery is discharged. Turn off the air conditioning, blower, radio, etc., and drive directly to the nearest Lexus dealer or repair shop. NOTICE Do not drive the vehicle with the warning light on - even for one block. It may ruin the engine. NOTICE Do not continue driving if the engine drive belt is broken or loose. 61
