DPF System Messages (Diesel only)
Under conditions of exclusive short
duration and low speed driving cycles,
the engine and exhaust after-
treatment system may never reach the
conditions required to remove the
trapped PM. If this occurs a message
will be displayed on the TFT display. By
driving your vehicle at highway speeds
for as little as 30 minutes, you can
remedy the condition in the
particulate filter system by allowing
the trapped PM to be removed to
restore the system to normal operating
condition.
Carefully follow the indications
visualized on the display until
regeneration is completed.

If the exhaust after-treatment system
requires service intervention, a
message will be displayed to alert the
driver.
In this condition the engine will be
derated to prevent permanent
damage to the after-treatment system.
If this condition occurs, it is necessary
to have your vehicle serviced by your
local Maserati Service Network.
