NOTICE
■ Notice on fuel quality
● Do not use improper fuels. If improper
fuels are used, the engine will be dam-
aged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to
your vehicle’s three-way catalytic con-
verters causing the emission control sys-
tem to malfunction.
●
Do not use gasohol other than the type
previously stated.
Other gasohol may cause fuel system
damage or vehicle performance prob-
lems.
● 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
and will void the vehicle warranty.
■ 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.
■ When refueling with gasohol
Take care not to spill gasohol. It can dam-
age your vehicle’s paint.
