■ If your engine knocks

accelerating or driving uphill. This
is normal and there is no need for
concern.
NOTICE
■ Notice on fuel quality
● Do not use improper fuels. If
improper fuels are used, the
engine will be damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause
damage to your vehicle’s three-
way catalytic converters caus-
ing 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 per-
formance 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 start-
ing, vaporization, engine knock-
ing, etc.) is encountered after
using a different type of fuel, dis-
continue the use of that type of
fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It
can damage your vehicle’s paint.
