% The availability of this function is dependent

Ac tive Parking Assist is an electro nic parking
assis tance sy stem, which uses ultrasound with th
e assis tance of there ve rsing camera and 360°
Camera. When you are driving forw ards up to
appr oximately 35 km/h, the sy stem automati‐
cally measures parking spaces on bo thsides of
th eve hicle.
As soon as all requ irements are met for sear ch‐
ing for parking spaces, theÇ display appears
in the multifunction displa y.
When Active Parking Assist has de tected park ing
spaces, theÈ display appears in the multi‐
function displa y.The ar rowsshow on which side
of thero ad de tected park ing spaces are located.
They are then shown in the media displa y.
The parking space can be selected as desired.
Depending on the location of the parking space,
th e parking direction (rear wards or forw ards)
can also be selec ted as desired.
When Active Parking Assist is activated, the turn
signal indicators are activated based on the cal‐
culated path of your vehicle.
When you are en tering or exiting a parking
space, the procedure is assis tedby acceleration,
braking, steering and gear changes. 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 will be cancelled in thefo l‐
lowing situations:

WARNING Risk of accident with high
per form ance tyres
The special tire tread in combination with the
optimised tyre compound means that the ri
sk of skidding and aquaplaning on wet
ro ads is inc reased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use i M+S tyres at outside temp er‐
atures of less than 10 °C. #
Only use the tyres forth eir intended
purpose. Obser
vethefo llowing when selecting, fitting and
re placing tyres:
R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle.
R Furthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
tyres) and the same make. R
Only fit wheels of the same size on one axle
(left and right).
It is only permissible tofit a di fferent wheel
size in theeve nt of a flat tyre in order to
drive tothe specialist workshop.
R Do not make any modifications tothe brake
sy stem, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may in validate theve hicle's
ge neral operating pe rmit.
