X Only depress theaccelerator pedalslightly.
Otherwise, non-combusted fuelmay getinto thecatalytic con-
verter anddamage it.
X Have thecause rectified immediately ataqual ified specialist

no longer beingcooled sufficiently.
X Stop assoon aspossible andallow theengine andthecoolant to
cool down.
X Check thecoolant level(Ypage 270). Observe thewarning notes
as you dosoand add coolant ifnecessary. If
the coolant leveliscorrect ,the engine radiator fanmay befaulty.
