IMPORTANT
¬
20) If, when the key is turned to MAR, the
warning light does not come on or if it stays on with the vehicle in motion (together with the
message on the display) there could be a failure in the safety systems; under these circumstances the airbags or pretensioners may not be
triggered in the event of an impact or, more rarely, they could be triggered accidentally. Before proceeding, contact a dedicated Alfa Romeo
Dealership to have the system checked immediately.
"
¬
21) Failure of the
warning light is signalled by the flashing for longer than the usual 4 seconds of the warning light. In addition, the airbag
¬
system automatically disables the passenger side airbag. In this case, the warning light may not indicate failures in the retaining systems.
Before proceeding, contact a dedicated Alfa Romeo Dealership to have the system checked immediately.
"
¬
22) A failure of the
warning light is indicated by the warning light. In addition, the airbag system automatically disables the passenger
side airbag.
23) Deteriorated engine oil should be replaced as soon as possible after the digital warning light comes on, and never more than 500 km after it
first switches on. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember that when the
digital 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.
24) If the warning light flashes with the car in motion, contact the dedicated Alfa Romeo Dealership.
WARNING
3) If, when the ignition key is turned to MAR, the warning light does not turn on or if it turns on constantly or flashes when travelling
(on certain versions, together with the message on the display), contact a dedicated Alfa Romeo Dealership as soon as possible.
