CATALYTIC CONVERTER
WARNING: Do not park, idle or driveyour vehicle on dry grass or other dryground cover. The emission system heatsup the engine compartment and exhaustsystem, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system is veryhigh. Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
WARNING: Exhaust leaks may resultin entry of harmful and potentially lethalfumes into the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 328).
•Use only the specified fuel listed.
