General notes
The vehicle level can be set using theDYNAMIC SELECT button (Ypage 132) or thelevel button. The setting always correspondsto the last selected function.
In order to reduce fuel consumption andimprove the driving dynamics, the vehicle islowered as its speed increases. In theSportandSport Plusdrive programs, it is loweredby up to 0.5 in (13 mm) compared to the nor-mal vehicle level. In theComfortandCURVEdrive programs, it is lowered by up to 0.2 in(5 mm) compared to the normal vehicle level.As the speed is reduced, the vehicle is raisedup to the set vehicle height.
Select the normal level for normal road surfa-ces and the raised level for driving with snowchains or on particularly poor road surfaces.
Important safety notes
GWARNING
The vehicle is lowered slightly in the follow-
ing situations:
Rthe SPORT suspension setting is selected

Active Parking Assist
General notes
Active Parking Assist is an electronic parkingaid with ultrasound. It measures the road onboth sides of the vehicle. A parking symbolindicates a suitable parking space. Activesteering intervention can assist you duringparking and when exiting a parking space. Youcan also still use Parking Assist PARKTRONIC(Ypage 172).
Important safety notes
Active Parking Assist is merely an aid. It is nota replacement for your attention to your imme-diate surroundings. You are always responsi-ble for safe maneuvering, parking and exiting aparking space. Make sure that no persons, ani-mals or objects are in the path of your vehicle.
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 overobstacles such as curbs slowly and at anobtuse angle. Otherwise, you may damagethe wheels or tires.
Active Parking Assist may also show parkingspaces which are not suitable for parking, forexample:
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 park-ing space as possible
Rparking spaces that are littered or over-grown might be identified or measuredincorrectly
Rparking spaces that are partially occupiedby trailer drawbars might not be identifiedas such 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 theparking procedure (Ypage 174)
Ryou can intervene in the steering procedureto correct it at any time. Active ParkingAssist will 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:
Rparallel or at right angles to the direction oftravel
Ron straight roads, not bends
Ron the same level as the road, e.g. not onthe pavement
Detecting parking spaces
Objects located above the detection range ofActive Parking Assist will not be detectedwhen the parking space is measured. These
are not taken into account when the parkingprocedure is calculated, e.g. overhangingloads, tail sections or loading ramps of trucks.Active Parking Assist may therefore guide youinto the parking space too early.
GWARNING
If there are objects above the detection
range:
Rthe Parking Package with rear view cam-
era 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.
Further information about the detection range(Ypage 173).
Active Parking Assist does not assist you park-ing in spaces at right angles to the direction oftravel if:
Xtwo parking spaces are located directly nextto one another
Xthe parking space is directly next to a lowobstacle such as a low curb
Xyou park forwards
Active Parking Assist does not assist 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 grasspaving blocks
Rthe area is too small for the vehicle tomaneuver into
Rthe parking space is bordered by an obsta-cle, e.g. a tree, a post or a trailer

Active Parking Assist no longer supports youwith steering interventions. When Active Park-ing Assist is finished, you must steer againyourself. Parking Assist PARKTRONIC is stillavailable.
Parking tips:
RThe way your vehicle is positioned in theparking space after parking is dependent onvarious factors. These include the positionand shape of the vehicles parked in frontand behind it and the conditions of the loca-tion. It may be the case that Active ParkingAssist guides you too far into a parkingspace, or not far enough into it. In somecases, it may also lead you across or onto
the curb. If necessary, cancel the parkingprocedure with Active Parking 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,the parking procedure is canceled. A sensi-ble parking position can no longer be ach-ieved from this position.
Exiting a parking space
In order that Active Parking Assist can supportyou when exiting the parking space:
Rthe border of the parking space must behigh enough at the front and the rear. Acurb is too small, for example.
Rthe border of the parking space must not betoo wide. Your vehicle can be maneuveredinto a position at a maximum of 45° to thestarting position in the parking space.
Ra maneuvering distance of at least 3.3 ft(1.0 m) 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.

Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LEDlighting (the display may flicker)
Rif there is a sudden change in temperature,e.g. when driving into a heated garage inwinter
Rif the camera lens is dirty or obstructed.Observe the notes on cleaning(Ypage 275)
Rif the rear of your vehicle is damaged. In thiscase, have the camera position and settingchecked at a qualified specialist workshop.
The field of vision and other functions of therear view camera may be restricted due toadditional accessories on the rear of the vehi-cle (e.g. license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,leaving the standard height can result in inac-curacies in the guide lines, depending on tech-nical conditions.

As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.

Monitoring area
GWARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient
distance on the side for other traffic or
obstacles.
Active Blind Spot Assist monitors the area upto 10 ft (3.0 m) behind your vehicle anddirectly next to your vehicle, as shown in thediagram.
The detection of obstacles can be impaired inthe case of:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rpoor visibility, e.g. due to rain, snow orspray
Vehicles in the monitoring range are then notindicated.
Active Blind Spot Assist may not detect narrowvehicles, such as motorcycles or bicycles, ormay only detect them too late.
If the lanes are narrow, vehicles driving in thelane beyond the lane next to your vehicle maybe indicated, especially if the vehicles are notdriving in the middle of their lane. This may bethe case if there are vehicles driving at theinner edge of their lanes.
