GAUGES, METERS AND SERVICE REMINDER INDICATORS (e) Discharge Warning Light This light warns that the battery is being discharged. If it comes on while you are driving, stop the vehicle, turn off the engine, and check for the cause. 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. (f) Malfunction Indicator Lamp This lamp comes on in the following cases. a. The fuel tank is completely empty. (See "Fuel gauge" on page 57 for instructions.) b. The fuel tank cap is not tightened securely. (See "Fuel tank cap" on page 114 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 down to about the middle position, there may be a problem somewhere in your electronic throttle control system. At this time, 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 key is turned to "ACC" or "LOCK" position. NOTICE Do not continue driving if the engine drive belt is broken or loose. 67
