Ac
tive Parking Assist Fu
nction of Active Parking Assist
Ac tive Parking Assist is an elect ronic pa rking
assis tance sy stem which uses ultrasound and is
automatically activated during forw ard tra vel.
The sy stem is operational at speeds below
appr oximately 35 km/h.
When all the conditions are fulfilled, thefo llow‐
ing symbol appears in the multifunction display
in the instrument clus ter: The sy
stem then independently locates and
measures parallel and perpendicular parking
spaces on bo thsides of theve hicle.
When Active Parking Assist has de tected pa rking
spaces, thefo llowing symbol appears in the mul‐
tifunction display in the instrument clus ter: The ar
rows show on which side of the car riage‐
wa y free parking spaces are located. They are
th en shown in the multimedia sy stem displa y.
The parking space and, if necessar y,the parking
direction can be selected as desired. Active
Pa rking Assist calculates a suitable vehicle path
and assists you in parking and exiting the park‐
ing space.
Ve hicles with automatic transmission: Active
Pa rking Assist supports with changing gear,
accelerating, braking and steering theve hicle.
Ve hicles with manual transmission: the active
brake application and automatic gear change are
on lyavailable on vehicles with automatic trans‐
mission. You must therefore brake theve hicle
and change gear yourself when parking or exit‐
ing a parking space.
Ac tive Parking Assist is only an aid. It is not a
substitute foryo ur attention tothe sur roundings.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that no
persons, animals or objects etc. are in the
manoeuvring range. Ac
tive Parking Assist is cancelled if, among
ot her things, one of thefo llowing actions is car‐
ri ed out:
R You deactivate Parking Assist PARKTRONIC.
R You deactivate Active Parking Assist.
R You begin steering.
R You apply the parking brake.

These are also not take n into account when the
parking manoeuvre is calculated, e.g. overhang‐
ing loads, overhangs or loading ramp s of lor ries
or the boundaries of parking spaces. In some cir‐
cums tances, Active Parking Assist may therefore
guide you into the parking space prematurely. 246
