Indication of incorrect position of the red starter
button
This message warns the user that the button should
be returned to the "upper" position in order to ensure
that there is not an excessive current absorption by
the system.
Important
This could lead to battery discharge in a short
time.
Any incorrect position is detected within the first 60
seconds after vehicle switch-off (Key-Off).
If you press switch (8) for over 1 second to turn
system off (Key-Off), the system will activate "RED
SWITCH NOT RELEASED" warning flashing on
display.
