Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronicparking aid with ultrasound. It monitors the areaaround your vehicle using six sensors in thefront bumper and six sensors in the rearbumper. Parking Assist PARKTRONIC visuallyand audibly indicates the distance between yourvehicle and an object.
Parking Assist PARKTRONIC is only an aid. It isnot a replacement for your attention to yourimmediate surroundings. You are alwaysresponsible for safe maneuvering, parking andexiting a parking space. Make sure that thereare no persons, animals or objects in the maneu-vering area when you are maneuvering or park-ing.
!When parking, pay particular attention toobjects above or below the sensors, such asflower pots or trailer drawbars. Parking AssistPARKTRONIC does not detect such objectswhen they are in the immediate vicinity of thevehicle. You could damage the vehicle or theobjects.
The sensors may not detect snow and otherobjects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic carwash, the compressed-air brakes of a truck ora pneumatic drill could cause Parking AssistPARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not functioncorrectly on uneven terrain.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking aidwith ultrasound. It measures the road on bothsides of the vehicle. A parking symbol indicatesa suitable parking space. Active steering inter-vention and brake application can assist youduring parking and when exiting a parkingspace. You can also still use Parking AssistPARKTRONIC (Ypage 162).
Important safety notes
Active Parking Assist is merely an aid. It is not areplacement for your attention to your immedi-ate surroundings. You are always responsiblefor safe maneuvering, parking and exiting aparking space. Make sure that there are no per-sons, animals or objects in the maneuveringarea when you are maneuvering or parking.
When Parking Assist PARKTRONIC is deactiva-ted, Active Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users or
objects. There is a risk of an accident.
Pay attention to other road users or objects.
Stop the vehicle if necessary or cancel the
Active Parking Assist parking procedure.
!If they cannot be avoided, drive over obsta-cles such as curbs slowly and at an obtuseangle. Otherwise, you may damage thewheels or tires.
Active Parking Assist may possibly indicateparking spaces which are not suitable for park-ing, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces

Parking tips:
ROn narrow roads, drive as close to the parkingspace as possible
RParking spaces that are littered or overgrownmight be identified or measured incorrectly
RParking spaces that are partially occupied bytrailer drawbars might not be identified assuch or be measured incorrectly
RSnowfall or heavy rain may lead to a parkingspace being measured inaccurately
RPay attention to the warning messages ofParking Assist PARKTRONIC during the park-ing procedure (Ypage 164).
RYou can intervene in the steering procedureto correct it at any time. Active Parking Assistwill then be canceled
RWhen transporting a load which protrudesfrom your vehicle, you should not use ActiveParking Assist
RNever use Active Parking Assist when snowchains are installed
RMake sure that the tire pressures are alwayscorrect. This has a direct influence on theparking characteristics of the vehicle.
Use Active Parking Assist for parking spaces:
Rthat are parallel or at right-angles to the direc-tion of travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not on thepavement
Detecting parking spaces
Objects located above the detection range ofActive Parking Assist will not be detected whenthe parking space is measured. These are nottaken into account when the parking procedureis calculated, e.g. overhanging loads, truck over-hangs or loading ramps. Active Parking Assistmay therefore guide you into the parking spacetoo early.
Active Parking Assist does not support you park-ing in spaces at right angles to the direction oftravel if:
Rtwo parking spaces are located directly nextto one another
Rthe parking space is directly next to a lowobstacle such as a low curb
Ryou park forwards
Active Parking Assist does not support you park-ing in spaces that are parallel or at right anglesto the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as beingblocked, for example by foliage or grass pav-ing blocks
Rthe area is too small for the vehicle to maneu-ver into
Rthe parking space is bordered by an obstacle,e.g. a tree, a post or a trailer
Further information about the detection range(Ypage 163).
GWARNING
If there are objects above the detection range:
Rthe Parking Package with rear view camera
may steer too early
Rthe vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate the Parking Pack-
age with rear view camera.

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. Parkingspaces on the driver's side are displayed assoon as the turn signal on the driver's side isactivated. When parking on the driver's side,this must remain activated until you confirm theuse of Active Parking Assist by pressing thevbutton on the multifunction steeringwheel. The system automatically determineswhether the parking space is parallel or at right-angles to the direction of travel.
A parking space is displayed while you are driv-ing past it, and until you are approximately 50 ft(15 m) away from it.

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.
