driving performance, and will cause damage to the fuel system c ompo-
nents. Therefore, do not add fuels such as the following.
● Fuels containing methanol
● Fuels with more than 85% ethanol
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine k nocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
