6-1. Specifications CAUTION ■ Notice on fuel quality ● Do not use improper fuels. If improper fuels are used the engine and/or fuel system will be damaged. ● Do not use leaded gasoline. Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters causing the emission control system to malfunction. ● Do not use gasohol other than that stated here. Other gasohol may cause fuel system damage or vehicle performance 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 after using a different type of fuel, poor driveability is encountered (poor hot starting, vaporization, engine knocking, etc.), 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. 6 Vehicle specifications 479
