When driving at speeds below 19 mph(30 km/h), you will see parking symbolDas astatus indicator in the instrument cluster. Whena parking space has been detected, an arrowtowards the right or the left also appears. Bydefault, Active Parking Assist only displays park-ing spaces on the front-passenger side.

Parking tips:
RThe way your vehicle is positioned in the park-ing space after parking is dependent on vari-ous factors. These include the position andshape of the vehicles parked in front andbehind it and the conditions of the location. Itmay be the case that Active Parking Assistguides you too far into a parking space, or notfar enough into it. In some cases, it may alsolead you across or onto the curb. If necessary,cancel the parking procedure with ActiveParking Assist.
RYou can also preselect transmission position[. The vehicle redirects and does not driveas far into the parking space. Should thetransmission change take place too early, theparking procedure is canceled. A sensibleparking position can no longer be achievedfrom this position.
Exiting a parking space
In order that Active Parking Assist can supportyou when exiting the parking space:
Ryou need to have parked using Active ParkingAssist.
Rthe border of the parking space must be highenough at the front and the rear. A curb stoneis too small, for example.
Rthe border of the parking space must not betoo wide, as the position of the vehicle mustnot exceed an angle of 45° to the startingposition as it is maneuvered into the parkingspace.
Ra maneuvering distance of at least 3.3 ft(1.0m) must be available.
Active Parking Assist can only assist you withexiting a parking space if you have parked thevehicle parallel to the direction of travel usingActive Parking Assist.

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front ofyour vehicle by means of multifunction cam-eraCwhich is attached behind the top of thewindshield. Lane Keeping Assist detects lanemarkings on the road and can warn you beforeyou leave your lane unintentionally.
This function is available in the range between40 mph and 120 mph (60 km/h and 200 km/h).
A warning may be given if a front wheel passesover a lane marking. It will warn you by means ofintermittent vibration in the steering wheel forup to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist cannot always clearly
detect lane markings.
In such cases, Lane Keeping Assist can:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Lane Keeping Assist alerts you.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-ing Assist can neither reduce the risk of an acci-dent nor override the laws of physics. LaneKeeping Assist cannot take into account theroad, traffic and weather conditions. Lane Keep-ing Assist is merely an aid. You are responsiblefor the distance to the vehicle in front, for vehi-cle speed, for braking in good time and for stay-ing in your lane.
The Lane Keeping Assist does not keep the vehi-cle in the lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too shortand thus the lane markings cannot be detec-ted
Rthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge
Rthe road is narrow and winding
Rthere are highly variable shade conditions onthe roadway
