GAUGES, METERS AND SERVICE REMINDER INDICATORS (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 level" on page 316.) 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 consumption" on page 314.) (h) Malfunction Indicator Lamp This lamp comes on when the ignition switch is turned to the "ON" position and goes off after the engine starts. This means that the warning light system is operating properly. If the lamp remains on, or the lamp comes on while driving, first check the following: D Empty fuel tank If the fuel tank is empty, refuel immediately. D Loose fuel tank cap If the fuel tank cap is loose, securely tighten it. These cases are temporary malfunctions. The malfunction indicator lamp will go off after taking several driving trips. If the lamp does not go off even after several trips, contact your Lexus dealer as soon as possible. If the fuel tank is not empty or the fuel tank cap is not loose...D There is a problem somewhere in the engine, emission control system, electronic throttle control system, automatic transmission electrical system or warning light system itself. Contact your Lexus dealer as soon as possible to service the vehicle. NOTICE Continued engine operation with low engine oil will damage the engine. 46
