WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of yourvehicle's emissions system and filters harmfulpollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
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.
To avoid damaging the catalytic converter:
•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 Precautions (page 318).
•Use the correct fuel. See Fuel andRefueling (page 203).
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Do not make any unauthorizedchanges to your vehicle or engine. By law,vehicle owners and anyone whomanufactures, repairs, or services a fleet ofvehicles are not permitted to intentionallyremove an emission control device orprevent it from working.

CHANGING THE 12V BATTERY
WARNING: Batteries normallyproduce explosive gases which can causepersonal injury. Therefore, do not allowflames, sparks or lighted substances tocome near the battery. When working nearthe battery, always shield your face andprotect your eyes. Always provide correctventilation.
WARNING: When lifting aplastic-cased battery, excessive pressureon the end walls could cause acid to flowthrough the vent caps, resulting in personalinjury and damage to the vehicle or battery.Lift the battery with a battery carrier or withyour hands on opposite corners.

•If vehicles are stored outside, theyrequire regular maintenance to protectagainst rust and weather damage.
•Make sure all linkages, cables, levers andpins under your vehicle are covered withgrease to prevent rust.
•Move vehicles at least 25 ft (7.5 m) every15 days to lubricate working parts andprevent corrosion.
•Fill the fuel tank with high-quality fueluntil the first automatic shutoff of the fuelpump nozzle.
Engine
•Change the engine oil and filter prior tostorage because used engine oil containscontaminants which may cause enginedamage.
•Start the engine every 15 days for aminimum of 15 minutes. Run at fast idlewith the climate controls set to defrostuntil the engine reaches normaloperating temperature.
•With your foot on the brake, shift throughall the gears while the engine is running.

•Component damage that your vehiclewarranty does not cover.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced vehicle performance.
•Reduced fuel economy.
An oil that displays this symbol conforms tocurrent engine, emission system and fueleconomy performance standards of ILSAC.
We recommend Motorcraft motor oil for yourvehicle. If Motorcraft oil is not available, usemotor oils of the recommended viscositygrade that display the API Certification Markfor gasoline engines.

Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery to theultimate purchaser or while it is in use.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessive exhaustsmoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.
•An open or pinched sensor hose.
