KEYS AND DOORS (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 293.) 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. (h) Malfunction Indicator Lamp This lamp comes on in the following cases. a. The fuel tank is completely empty. (See "Fuel gauge" on page 36 for instructions.) b. The fuel tank cap is not tightened securely. (See "Fuel tank cap" on page 87 for instructions.) c. There is a problem somewhere in your engine electrical system, automatic transmission electrical system or electronic throttle control system. If it comes on while you are driving in case "c.", have your vehicle checked/repaired by your Lexus dealer as soon as possible. If this lamp comes on and the engine speed does not increase with the accelerator pedal depressed, there may be a problem somewhere in your electronic throttle control system. At this time, vibrations may occur. However, if you depress the accelerator pedal more firmly and slowly, you can drive your vehicle at low speeds. Have your Lexus checked by your Lexus dealer as soon as possible. Even if the abnormality of the electronic throttle control system is corrected during low speed driving, the system may not be recovered until the engine is stopped and the ignition switch is turned to "ACC" or "LOCK" position. NOTICE Continued engine operation with low engine oil will damage the engine. 44 SC430 through 12/2001 Production
