NOTICE
■Notice on fuel quality

an octane number or rating
lower than the level previously
stated may cause persistent
heavy knocking.
At worst, this may lead to
engine damage and will void the

Take care not to spill gasohol. It
can damage your vehicle’s paint.
■Fuel-related poor driveability
If poor driveabilit y (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.
