07 04.26 (f) 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 followings. Contact your Toyota 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. 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 vehicle checked by your Toyota 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 the "ACC" or "LOCK" position. 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 Toyota dealer to check your vehicle's emission control system and OBD (On−Board Diagnostics) system before taking your vehicle for the inspection. For details, see "Emissions Inspection and Maintenance (I/M) programs" in Section 6. (g) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.) This light acts as a reminder to replace the engine oil. This light will come on when the ignition switch is turned to the "ON" position and will go off after about a few seconds. When you drive for about 7200 km (4500 miles) after the engine oil replacement, this light illuminates for about 3 seconds and then flashes for about 12 seconds with the ignition switch turned to the "ON" position. If you continue driving without replacing the engine oil, and if the distance driven exceeds 8000 km (5000 miles), the light will come on after the ignition switch is turned to "ON" position. The light will remain on thereafter. 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 Toyota dealer as soon as possible. If the fuel tank is not empty or the fuel tank cap is not loose... CAUTION Be especially careful to prevent erroneous pedal operation. 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. 202 2007 TUNDRA from Jul.
