65) Deteriorated engine oil should be replaced as soon as possible after the warning light comes on, and never more
than 500 km after it first switches on. Failure to observe the above indications may result in severe damage to the
engine and invalidate the warranty. Remember that when this warning light comes on, it does not mean that the level
of engine oil is low, so if it flashes you must not top up the engine oil.
66) If the warning light flashes with the car in motion, contact an Alfa Romeo Dealership.
