If, turning the ignition key to
MAR, the warning light
U
does not turn on or if it turns
on glowing steadily or flash-
ing when travelling (on certain versions
together with the message on the dis-
play), contact Fiat Dealership as soon
as possible. Warning light U operation
can be checked by traffic agents by
proper equipment. Comply with laws
and regulations of the country where
you are driving.
If the light flashes, it is necessary to release
the accelerator pedal to lower the speed
of the engine until the warning light stops
flashing; continue the journey at moder-
ate speed, trying to avoid driving condi-
tions that may cause further flashing and
contact Fiat Dealership as soon as possi-
ble. EOBD engine control system
failure
Under normal conditions, turning the ig-
nition key to MAR, the warning light turns
on, but it should go out as soon as the en-
gine is started. The initial turning on indi-
cates that the warning light is working prop-
erly. If the warning light stays on or turns
on when travelling:
❒ 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 consumption levels.
On certain versions the dedicated mes-
sage is displayed.
In these conditions it is possible to con-
tinue driving without however requiring
heavy effort or high speed from the en-
gine. Prolonged use of the car with the
warning light on may cause damages. Con-
tact Fiat Dealership as soon as possible.
The warning light goes off if the fault dis-
appears, but it is still stored by the system.
❒ flashing: indicates the possibility of
damage to the catalyst (see “EOBD
system” in section “Dashboard and
controls”).
