Maintenance Operating precautions for catalytic converters WARNING - Fire A hot exhaust system can ignite flammable items under your vehicle. Do not park the vehicle over or near flammable objects, such as grass, vegetation, paper, leaves, etc. Your vehicle is equipped with a catalytic converter emission control device. Therefore, the following precautions must be observed: • Use only UNLEADED FUEL for gasoline engine. • Do not operate the vehicle when there are signs of engine malfunction, such as misfire or a noticeable loss of performance. • Do not misuse or abuse the engine. Examples of misuse are coasting with the ignition off and descending steep grades in gear with the ignition off. • Do not operate the engine at high idle speed for extended periods (5 minutes or more). • Do not modify or tamper with any part of the engine or emission control system. All inspections and adjustments must be made by an authorized Hyundai dealer. • Avoid driving with a very low fuel level. If you run out of gasoline, it could cause the engine to misfire and result in excessive loading of the catalytic converter. Failure to observe these precautions could result in damage to the catalytic converter and to your vehicle. Additionally, such actions could void your warranties. 7 67
