Indication of incorrect position of the red starter
button
This message tells you that the button should be
returned to the "top" position in order to ensure that
there is not an excessive current absorption by the
system.
Important
This could lead to battery discharge within a
short time.
Any incorrect position is detected within the first 60
seconds after vehicle switch-off (Key-Off).
If you press the starter button (1, fig. 85) for over 1
second to switch off (Key-Off), system activates the
warning "RED SWITCH NOT RELEASED" as a
flashing message (fig. 84).
