This check can also be carried out bytraffic control authorities.Contact an Abarth Dealership as soon aspossible if warning light U either doesnot light up when the key is turned toMAR or if while travelling it comes on eithersteady or blinking (along with a message on themultifunctional display, where provided).The operation of the U warning light may bechecked by the traffic control authorities usingspecific devices. Always comply with the trafficregulations in force in the country where you aredriving.IMPORTANT After eliminating the failure, to check thesystem completely, Abarth Dealerships run a bench testand, if necessary, road tests which may require a longjourney.
