■Notice on fuel quality

damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic

stated.
Other gasohol may cause fuel system damage or vehicle performance
problems.

level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ When use of non-specified fuels (Flex-fuel engine)
The use of non-specified fuels will have a negative impact on starting and
driving performance, and will cause damage to the fuel system compo-
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 knocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.

Take care not to spill gasohol. It can damage your vehicle’s paint.
