Audible signal

The Park Assist system uses an intermittent tone that pulses faster as you come close to an object, and becomes constant when you are within approximately 1 ft (30 cm) of an object in front of or behind the vehicle. If there are objects within this distance both behind and in front of the vehicle, the tone alternates between front and rear speakers.
NOTE
The level of the audible signal can be lowered/ raised with the infotainment volume control. The level can also be set in the MY CAR menu system, see page 134.
If the volume of another source from the audio system is high, this will be automatically lowered.
