The parking distance sensors activates
automatically when the ignition is switched
on and reverse gear is engaged.
Its operational readiness is indicated by
illumination of the LED in the button.
If the vehicle approaches an obstacle when
reversing, a series of signals can be heard
in the vehicle interior. The interval between
the signals becomes shorter as the
distance is reduced. If the distance is less
than 30 cm, the signal will be continuous.
