IMPORTANT
Depending on the characteristics and
GB
functions of the DEF fluid circulation
system, topping up is necessary only
when the DEF fluid level indicator
shows a value below 50% and not lower
than 15% of content (corresponding to
a minimum value of approx. two litres
of DEF fluid) fig. 4.
IMPORTANT
If the engine is used with DEF fluid
quantity lower than 15%, the system
generates a protection warning: both
the MIL and DWS warning lights turn
on with light steady on (fig. 5). Top up
the DEF fluid in the tank (as described
on page 39). When the topping up has
been carried out, start the engine to
allow MIL and DWS warning light reset.
Turn off the engine after reset.
If the engine is used with DEF fluid
quantity lower than 5%, the system
generates another protection warning:
the MIL warning light turns steady
on and the DWS warning light turns
flashing on. When the topping up has
been carried out, start the engine to
allow MIL and DWS warning light reset.
Turn off the engine after reset.
IMPORTANT
If MIL and DWS warning lights turn
on with a quantity of DEF fluid in
the tank greater than the minimum
quantity (15%), promptly contact the
manufacturer of the vehicle in which
the engine is installed or a workshop
authorised by VM MOTORI STELLANTIS
EUROPE.

IMPORTANT
Without DEF liquid, the engine
continues to run only at a reduced
speed, in an unsuitable state of use
(signalled by the DWS warning light on
and the MIL warning light on).
IMPORTANT
Avoid frequent filling with a percentage
level of DEF fluid equal to or greater
than 50%, as the system may generate
a plausibility error in the actual
consumption of DEF fluid.
