FUEL AND REFUELING
PRECAUTIONS
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: The fuel system may beunder pressure. If you hear a hissing soundnear the fuel filler inlet, do not refuel untilthe sound stops. Otherwise, fuel may sprayout, which could cause serious personalinjury.
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Fuel may containbenzene, which is a cancer-causing agent.
WARNING: When refueling alwaysshut the engine off and never allow sparksor open flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
WARNING: Read and follow all theinstructions on the pump island.
Follow these guidelines when refueling:
•Extinguish all smoking materials and anyopen flames before refueling yourvehicle.
•Switch the engine off before refueling.
•Automotive fuels can be harmful or fatalif swallowed. Fuel is highly toxic and ifswallowed can cause death or permanentinjury. If fuel is swallowed immediatelycall a physician, even if no symptoms areimmediately apparent. The toxic effectsof fuel may not be apparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases, excessiveor prolonged breathing of fuel vapor cancause serious illness and permanentinjury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses, if worn, flush withwater for 15 minutes and seek medicalattention. Failure to seek proper medicalattention could lead to permanent injury.

RUNNING OUT OF FUEL
FILLING A PORTABLE FUELCONTAINER
WARNING: Flow of fuel through afuel pump nozzle can produce staticelectricity. This can cause a fire if you arefilling an ungrounded fuel container.
Use the following guidelines to avoidelectrostatic charge build-up, which canproduce a spark, when filling an ungroundedfuel container:
•Only use an approved fuel container totransfer fuel to your vehicle. Place thecontainer on the ground when filling it.
•Do not fill a fuel container when it isinside your vehicle (including the cargoarea).
•Keep the fuel pump nozzle in contactwith the fuel container when filling it.
•Do not use a device that holds the fuelpump nozzle lever in the fill position.
ADDING FUEL FROM A PORTABLEFUEL CONTAINER
WARNING: Do not insert the nozzleof a fuel container or an aftermarket funnelinto the fuel filler neck. This may damagethe fuel system filler neck or its seal andcause fuel to run onto the ground.
WARNING: Do not pry open the fueltank filler valve. This could damage the fuelsystem. Failure to follow this instructioncould result in fire, personal injury or death.
WARNING: Do not dispose of fuel inthe household refuse or the public sewagesystem. Use an authorized waste disposalfacility.
When refueling the vehicle fuel tank from afuel container, use the fuel filler funnelincluded with your vehicle. See Locatingthe Fuel Filler Funnel (page 212).
Note:Do not use aftermarket funnels as theymay not work with the capless fuel systemand can damage it.
When refueling the vehicle fuel tank from afuel container, do the following:
1.Fully open the fuel filler door.
2.Fully insert the fuel filler funnel into thefuel filler inlet.
3.Add fuel to your vehicle from the fuelcontainer.
4.Remove the fuel filler funnel.
5.Fully close the fuel filler door.

6.Clean the fuel filler funnel and place itback in your vehicle or correctly disposeof it.
Note:If your vehicle runs out of fuel add aminimum of 1.3 gal (5 L) of fuel to restart theengine.
Note:You may need to switch the ignitionfrom off to on several times after refuelingto allow the fuel system to pump the fuelfrom the tank to the engine. When restarting,cranking time takes a few seconds longerthan normal.

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 the Vehicle (page 391).
•Use the correct fuel. See Fuel andRefueling (page 211).
•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.
