NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engi ne will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way ca talytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performan ce
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ 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.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
