Lincoln Nautilus: Catalytic Converter

What Is the Catalytic Converter

The catalytic converter is part of your vehicle's emissions system and filters harmful pollutants from the exhaust gas.

Catalytic Converter Precautions

WARNING: Do not park, idle or drive your vehicle on dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, creating the risk of fire.

WARNING: The normal operating temperature of the exhaust system is very high. Never work around or attempt to repair any part of the exhaust system until it has cooled. Use special care when working around the catalytic converter. The catalytic converter heats up to a very high temperature after only a short period of engine operation and stays hot after the engine is switched off.

To avoid damaging the catalytic converter:

  • Do not crank the engine for more than 10 seconds at a time.
  • Do not run the engine with a spark plug lead disconnected.
  • Do not push-start or tow-start your vehicle. Use booster cables. See Jump Starting Precautions.
  • Use the correct fuel. See Fuel and Refueling.
  • Do not switch the ignition off when your vehicle is moving.
  • Avoid running out of fuel.
  • Have the items listed in scheduled maintenance information performed according to the specified schedule.

Note: Do not make any unauthorized changes to your vehicle or engine. By law, vehicle owners and anyone who manufactures, repairs, or services a fleet of vehicles are not permitted to intentionally remove an emission control device or prevent it from working.
