but it should go off when the engine has
started. The initial turning on indicates that
the warning light is working properly.
If the warning light stays on or turns on
when travelling (together with message +
symbol on the display):
glowing steadily- means a fault in the
supply/ignition system which could cause
high emissions at the exhaust, possible lack
of performance, poor handling and high con-
sumption levels. In these conditions it is pos-
sible to continue driving without however re-
quiring heavy effort or high speed from the
engine. Prolonged use of the car with the
warning light on may cause damages. Con-
tact Alfa Romeo Authorized Services as soon
as possible. The warning light goes off if the
fault disappears, but it is however stored by
the system;

EOBD SYSTEM
(upon request for versions/
markets where applicable)
The EOBD system (European On Board Di-
agnosis) allows continuous diagnosis of the
components of the car correlated with emis-
sions.
It also alerts the driver, by turning on the
warning light
Uon the instrument panel
(on certain versions together with message
+ symbol on the reconfigurable multifunc-
tion display), when these components are
no longer in peak conditions.
The objective is:
– to keep the system efficiency under con-
trol;
– to warn when a fault causes emissions
levels to increase;
– to warn of the need to replace deterio-
rated components.The system also has a diagnostic connec-
tor that can be interfaced with appropriate
tools, which makes it possible to read the
error codes stored in the control unit, to-
gether with a series of specific parameters
for engine operation and diagnosis. This
check can also be carried out by the traffic
police.IMPORTANTAfter eliminating the in-
convenience, to check the system com-
pletely, Alfa Romeo Authorised Services are
obliged to run a bench test and, if necessary,
road tests which may also call for a long jour-
ney.
If, turning the ignition key
to MAR, the warning light
Udoes not turn on or if,
while travelling it turns on glow-
ing steadily or flashing (on some
versions together with the mes-
sage + symbol on the reconfig-
urable multifunction display), con-
tact Alfa Romeo Authorised Ser-
vices as soon as possible.
