GAUGES, METERS AND SERVICE REMINDER INDICATORS If the system fails to reset, the light will remain flashing. In this case, return to step 1 and try again. At this time, vibration 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 key is turned to "ACC" or "LOCK" position. (f) Malfunction Indicator Lamp This lamp comes on when the ignition key 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. If engine speed does not increase when the accelerator pedal is depressed, there may be a problem somewhere in the electronic throttle control system. CAUTION Be especially careful to prevent erroneous pedal operation. Emissions inspection and maintenance (I/M) programs Your vehicle may not pass a state emission inspection if the malfunction indicator lamp remains on. Contact your Lexus dealer to check your vehicle's emission control system and OBD (On-Board Diagnostics) system before taking your vehicle for the inspection.
