Ac tive Parking Assist is an electronic parking assis-

measures parking spaces on bo thsides of the

speed of appr oximately 35 km/h.
If all requ irements are met, theÇ display
appears in the inst rument cluster displa y.The sys-
te m then independently locates and measures par-
allel and perpendicular parking spaces on bo th
sides of theve hicle.
When Active Parking Assist has de tected parking
spaces, theÈ display appears in the inst ru-

on the driver's side are only displa yed if you oper-
ate the turn signal on the driver's side. When par k-
ing on the driver's side, you must operate the turn
signal until you ha vestar ted active parking assis-
ta nce bypressing thea steering-wheel button.
Ac tive Parking Assist can assist you with an active
steering inter vention and brake application during
parking and exiting the parking space. The active brake application is dependent on
the countr y-spe-
ci/c version of theve hicle. On vehicles with man-
ual transmission, active parking assis tance is limi-
