cates visually and audibly the dis tance between
yo ur vehicle and an object.
Pa rking Assist PARKTRONIC is on lyan aid. It is
not a substitute foryo ur attention tothe sur‐

th ere are no persons, animals or objects in the
maneuvering area while maneuvering and parking
in/exiting parking spaces.
In thest andard setting, an intermit tent wa rning

1. 3 ft (0.4 m) toan obs tacle. A continuous tone
sounds from a di stance of appr oximately 1.0 ft
