You may experience a decrease in peakperformance when the engine is cold whenoperating on E85 ethanol.
Do not crank the engine for more than 10seconds at a time as starter damage mayoccur. If the engine fails to start, turn thekey to off and wait 30 seconds beforetrying again.
Do not use starting fluid such as ether inthe air intake system. Such fluid couldcause immediate explosive damage to theengine and possible personal injury.
If you should experience cold weatherstarting problems on E85 ethanol, andneither an alternative brand of E85 ethanolnor an engine block heater is available, theaddition of unleaded gasoline to your tankimproves cold starting performance. Yourvehicle is designed to operate on E85ethanol alone, unleaded gasoline alone, orany mixture of the two.

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel sprayand fire.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler door, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Automotive fuels can cause seriousinjury or death if you misuse ormishandle them.
Fuel ethanol and gasoline maycontain benzene, which is acancer-causing agent.
When refueling always shut theengine off and never allow sparks oropen flames near the filler neck.Never smoke or use a cell phone whilerefueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
The flow of fuel through a fuel pumpnozzle can produce static electricity,which can cause a fire if you pumpfuel into an ungrounded fuel container.
Observe the following guidelines whenhandling automotive fuel:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Automotive fuels can be harmful orfatal if swallowed. Fuel such asgasoline is highly toxic and ifswallowed can cause death orpermanent injury. If swallowed, call aphysician immediately, even if nosymptoms are immediately apparent.The toxic effects of fuel may not bevisible for hours.
•Avoid inhaling fuel vapors. Inhaling toomuch fuel vapor of any kind can leadto eye and respiratory tract irritation.In severe cases, excessive or prolongedbreathing of fuel vapor can causeserious illness and permanent injury.
•Avoid getting fuel liquid in your eyes. Ifyou splash fuel in your eyes, removecontact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek propermedical attention could lead topermanent injury.
•Fuels can also be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andwash your skin thoroughly with soapand water. Repeated or prolonged skincontact with fuel liquid or vapor causesskin irritation.
•Be particularly careful if you are taking“Antabuse” or other forms of disulfiramfor the treatment of alcoholism.Breathing gasoline vapors, or skincontact could cause an adversereaction.
