Do not be concerned if your vehicle sometimes
knocks lightly when you drive up a hill or when
you accelerate. However, if a fuel with the
recommended octane rating knocks heavily
under all driving conditions or knocks lightly
driving at cruising speed on level roads, see
your dealer or a qualified service technician.
Persistent, heavy knocking can damage the
engine.
