2006 Lexus RX 330 Owners Manual - Page 408

STARTING AND DRIVING NOTICE A large amount of unburned gases flowing into the three−way catalytic converter may cause it to overheat and create a fire hazard. To prevent this and other damage, observe the following precautions: D Use only unleaded gasoline. D Do not drive with an extremely low fuel level; running out of fuel could cause the engine to misfire, creating an excessive load on the three−way catalytic converter. D Do not allow the engine to run at idle speed for more than 20 minutes. D Avoid racing the engine. D Do not push−start or pull−start your vehicle. D Do not turn off the ignition while the vehicle is moving. D Keep your engine in good running order. Malfunctions in the engine electrical system, electronic ignition system or fuel system could cause an extremely high three−way catalytic converter temperature. D If the engine becomes difficult to start or stalls frequently, take your vehicle in for a check−up as soon as possible. Remember, your Lexus dealer knows your vehicle and its three−way catalytic converter system best. D To ensure that the three−way catalytic converter and the entire emission control system operate properly, your vehicle must receive the periodic inspections required by the Lexus Maintenance Schedule. For scheduled maintenance information, refer to the "Owner's Manual Supplement / Scheduled Maintenance". 383
