If it is not clear whether the fuel contains such additives, ask the station operator for further information
regarding the detergency of their gasolines.
Gasoline Containing Alcohol
Some fuel suppliers sell gasoline containing alcohol without advertising the presence of alcohol. If you
are not sure whether there is alcohol in the gasoline you buy, check with the service station operator.
Blends of unleaded gasoline and ethanol (ethyl alcohol, grain alcohol), sometimes called "gasohol", are
available in some areas. Gasohol, if used, must contain no more than 10 percent ethanol and must have
an (R+M)/2 rating of 87 or higher. If you experience problems with starting, drive ability, or fuel
economy with gasohol, you should discontinue its use.
Take care not to spill gasoline during refueling. Gasolines containing alcohol can cause damage to
painted surfaces, which may not be covered under the New Vehicle Limited Warranty.
Caution:
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in
vehicle performance deterioration and can damage critical parts in the fuel system. Such damage may
not be covered under the New Vehicle Warranty.
Fuel Tank
The fuel tank is designed to hold approx. 15.8 US gal. (60 liters), with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather.
Be aware that the "usable" tank capacity will be somewhat less than the 15.8-US gal. (60-liter)
maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate
supply of fuel. Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone.
After the needle enters the red zone, you should be able to drive approx. 25 miles (40 km) depending on
driving style and conditions.
