STARTING AND DRIVING 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 separate "Owner's Manual Supplement/ Maintenance Schedule". ENGINE EXHAUST CAUTION 270
