ENGINE Gasoline quality In a very few cases, you may experience driveability problems caused by the particular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If this does not rectify your problem, then consult your Lexus dealer. FUEL PUMP SHUT OFF SYSTEM The fuel pump shut off system stops supplying fuel to the engine to minimize the risk of fuel leakage when the engine stalls or an airbag inflates upon collision. To restart the engine after the fuel pump shut off system activates, turn the ignition switch to "ACC" or "LOCK" once and start it. NOTICE D Do not use gasohol other than stated above. It will cause fuel system damage or vehicle performance problems. D If drivability problems are encountered (poor hot starting, vaporizing, engine knock, etc.), discontinue its use. D Take care not to spill gasohol during refueling. Gasohol may cause paint damage. CAUTION Inspect the ground under the vehicle before restarting the engine. If you find that liquid has leaked onto the ground, it is the fuel system that has been damaged and it is in need of repair. In this case, do not restart the engine.
