There�may�be�other�functional�limitations�in�the�following�situations,�for�example:
• if�the�sensors�are�soiled�or�iced�up
• in�heavy�fog,�rain�or�snow
• on�uneven�surfaces,�e.g.�gravel�roads
• on�slippery�surfaces
• on�steep�inclines�or�downhill�gradients
• if�leaves�have�gathered�or�snow�has�piled�up�in�the�parking�space.
To�ensure�the�ultrasonic�sensors�remain�fully�operational,�they�must�be�kept�clean�and�free�of�ice.
When�cleaning�the�sensors�using�a�high�pressure�cleaner,�avoid�direct�and�sustained�contact�with�a
high-pressure�water�jet.�Furthermore,�when�using�high�pressure�cleaners,�a�distance�of�at�least�30cm
from�the�sensors�must�be�maintained.
The�Parking�Maneuver�Assistant�PMA�cannot�replace�the�driver's�personal�judgement�of�the�traffic
situation.�Also�check�the�traffic�situation�around�the�vehicle�by�looking�around,�otherwise�there�may
be�a�risk�of�an�accident�as�a�result�of�road�users�or�objects�which�lie�outside�the�detection�range�of
the�Park�Distance�Control.�Loud�sound�sources�outside�and�inside�the�vehicle�may�mask�the�acoustic
signals�of�the�Parking�Maneuver�Assistant�PMA�or�the�Park�Distance�Control�PDC.
