according to the analysis of vehicle dynamic
conditions.
This means that automatic switch-off is triggered
when vehicle speed exceeds 20 km/h (12.4 mph)
after the turn indicator button was pressed.
Turn indicators also switch off automatically if they
remained on for a long mileage, which can range
between 200 and 2000 metres (656-6562 feet),
depending on vehicle speed when the turn indicator
button was pressed.
If the turn indicator switch is again operated, while
turn indicator is still on, automatic switch-off feature
is re-initialised.
Note
At any moment, if the instrument panel finds
that the ABS control unit is in error, system will
disable the set automatic switch-off strategy (so
turn indicators will not be disabled automatically).
