Maintenance and Specifications gasoline. "Premium" unleaded gasoline is not recommended because it may cause these problems to become more pronounced. If the problems persist, see your authorized dealer. FFV engine (if equipped) Your FFV will operate well on ordinary "Regular" unleaded gasoline, but only the highest quality fuel ethanol will provide the same level of protection and performance. To identify if your vehicle is an FFV, check your VIN or the label on the inside of your fuel filler door. When checking the VIN, look for the engine type identifier (8th character). If your vehicle is an FFV, then the character will be labeled as a "2". If you operate your vehicle 50% or more of the time on ethanol, you should follow a different maintenance schedule. In addition to this it is also recommended to fill the fuel tank with regular unleaded gasoline once every 3,000 miles (4,828 km). See scheduled maintenance information for more information. If you are experiencing a rough or rolling idle after start-up with the outside temperature above 80° F (27° C), the idle should improve within 10 to 30 seconds. If the problems persist below this temperature, see your authorized dealer. Running out of fuel Avoid running out of fuel because this situation may have an adverse effect on powertrain components. If you have run out of fuel: • You may need to cycle the ignition from OFF to ON several times after refueling to allow the fuel system to pump the fuel from the tank to the engine. On restarting, cranking time will take a few seconds longer than normal. • Normally, adding one gallon of fuel is enough to restart the engine. If the vehicle is out of fuel and on a steep grade, more than one gallon may be required. • The indicator may come on. For more information on the "check engine" or the "service engine soon" indicator, refer to Warning lights and chimes in the Instrument Cluster chapter.
