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.

Rwarnings may be issued in error when driv-ing close to crash barriers or similar solidlane borders.
Rwarnings may be interrupted when drivingalongside particularly long vehicles, e.g.trucks, for a prolonged time.
Indicator and warning display
CYellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at speedsbelow approximately 20 mph (30 km/h). Vehi-cles in the monitoring range are then not indi-cated.
When Active Blind Spot Assist is activated,indicator lampCin the exterior mirrors lightsup yellow at speeds of up to 20 mph(30 km/h). At speeds above 20 mph(30 km/h), the indicator lamp goes out andActive Blind Spot Assist is operational.
If a vehicle is detected within the monitoringrange at speeds above approximately 20 mph(30 km/h), warning lampCon the corre-sponding side lights up red. This warningalways occurs when a vehicle enters the moni-toring range from behind or from the side.When you overtake a vehicle, the warning onlyoccurs if the difference in speed is less than7 mph (12 km/h).
The yellow indicator lamp goes out if reversegear is engaged. In this event, Active BlindSpot Assist is no longer active.
The brightness of the indicator/warning lampsis adjusted automatically according to theambient light.
Visual and acoustic collision warning
If you switch on the turn signals to changelanes and a vehicle is detected in the sidemonitoring range, you receive a visual andacoustic collision warning. You will then hear a
double warning tone and red warning lampCflashes. If the turn signal remains on, detectedvehicles are indicated by the flashing of redwarning lampC. There are no further warningtones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of alateral collision in the monitoring range, acourse-correcting brake application is carriedout. This is meant to assist you in avoiding acollision.
GWARNING
A course-correcting brake application can-
not always prevent a collision. There is a risk
of an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake
application. Always maintain a safe distance
at the sides.
If a course-correcting brake applicationoccurs, red warning lampCflashes in theexterior mirror and a dual warning tonesounds. In addition, displayDunderlining thedanger of a side collision appears in the multi-function display.
In very rare cases, the system may make aninappropriate brake application. A course-cor-recting brake application may be interruptedat any time, e.g. if you steer slightly in theopposite direction or depress the acceleratorpedal more firmly.
The course-correcting brake application isavailable in the speed range between 20 mph(30 km/h) and 120 mph (200 km/h).

In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake applica-
tion
Rneither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, espe-
cially if Active Lane Keeping Assist alerts
you. Terminate the intervention in a non-crit-
ical driving situation.
The system may be impaired or may not func-tion if:
Rthere is poor visibility, e.g. due to insuffi-cient illumination of the road, or due tosnow, rain, fog or heavy spray
Rthere is glare, e.g. from oncoming traffic,the sun or reflection from other vehicles(e.g. if the road surface is wet)
Rthe windshield is dirty, fogged up, damagedor covered, for instance by a sticker, in thevicinity of the camera
Rthere are no lane markings, or severalunclear lane markings are present, e.g.around construction sites
Rthe lane markings are worn away, dark orcovered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is tooshort and thus the lane markings cannot bedetected
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 conditionson the roadway
Rno vehicle is detected in the adjacent laneand there are broken lane markings
Warning vibration in the steering wheel
A warning may be given if a front wheel passesover a lane marking. You will then be warnedby means of a vibration through the steeringwheel lasting for up to 1.5 seconds.
In order that you are warned only when neces-sary and in good time if you cross the lanemarking, the system detects certain condi-tions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on abend
Rthe road has very wide lanes, e.g. a freeway
Rthe system detects solid lane markings
The warning vibration occurs later if:
Rthe road has narrow lanes
Ryou cut the corner on a bend
Lane-correcting brake application
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the origi-
nal lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist
warns you or makes a lane-correcting brake
application.
GWARNING
Active Lane Keeping Assist only detects traf-
fic conditions or road users to a limited
extent. In very rare cases, the system may
make an inappropriate brake application,
e.g. after intentionally driving over a solid
lane marking. There is a risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly
in the opposite direction. Always make sure
that there is sufficient distance on the side
for other traffic or obstacles.
In rare cases, Active Lane Keeping Assistcould detect broken line markings or specialstructures on the road surface as solid lanemarkings. An inappropriate brake applicationcan be interrupted at any time, for example ifyou steer slightly in the opposite direction.

Driving and parking

If you leave your lane, under certain circum-stances the vehicle will brake briefly on oneside. This is meant to assist you in bringing thevehicle back to the original lane.
If a lane-correcting brake application occurs,displayCappears in the multifunction dis-play.
A lane-correcting brake application can bemade after driving over a lane marking recog-nized as being solid or broken. Before this, awarning must have been issued by means of avibration through the steering wheel. In addi-tion, a lane with lane markings on both sidesmust have been detected.
In the case of a broken lane marking beingdetected, a lane-correcting brake applicationcan only be made if a vehicle has been detec-ted in the adjacent lane. The following vehiclescan have an influence on brake application:oncoming traffic, vehicles that are overtakingand vehicles that are driving parallel to yourvehicle.
iA further lane-correcting brake applicationcan only occur after your vehicle hasreturned to the original lane.
No lane-correcting brake application occurs if:
Ryou clearly and actively steer, brake oraccelerate
Ryou cut the corner on a sharp bend
Ryou have switched on the turn signal
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind SpotAssist
Ryou have adopted a sporty driving style withhigh cornering speeds or high rates of accel-eration

Rthe transmission is not in position[
Ran obstacle has been detected in the lane inwhich you are driving
Rwhen a loss of tire pressure or a defectivetire has been detected and displayed
There is a possibility that the Active LaneKeeping Assist could misjudge the given trafficsituation. An inappropriate brake applicationmay be interrupted at any time if you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Rclearly brake or accelerate
A lane-correcting brake application is interrup-ted automatically if:
Ra driving safety system intervenes, e.g.

General notes
The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. More information can be found inthe Digital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the
vehicle when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the traffic
situation permits. If you are not sure that
this is possible, park the vehicle paying
attention to traffic conditions and operate
the equipment when the vehicle is station-
ary.
You must observe the legal requirements forthe country in which you are currently drivingwhen operating the multimedia system.
The multimedia system calculates the route tothe destination without taking the followinginto account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rules and regulations
The multimedia system may give incorrect nav-igation recommendations if the actual street/traffic situation does not correspond with thedigital map's data.
For example:
Ra diverted route
Rthe road layout or the direction of a one-waystreet has been changed
For this reason, you must always observe roadand traffic rules and regulations during yourjourney. Road and traffic rules and regulationsalways have priority over multimedia systemdriving recommendations.
Navigation announcements are intended todirect you while driving without diverting yourattention from the road and driving.
Please always use this feature instead of con-sulting the map display for directions. Lookingat the icons or map display can distract youfrom traffic conditions and driving, andincrease the risk of an accident.
This equipment complies with FCC radiationexposure limits set forth for uncontrolledequipment and meets the FCC radio frequency(RF) Exposure Guidelines in Supplement C toOET65.
This equipment has very low levels of RFenergy that is deemed to comply without maxi-mum permissive exposure evaluation (MPE).However, it is recommended to install it at adistance of at least 8 inches (approx. 20 cm)between the radiation source and a person'sbody (not including limbs such as hands,wrists, feet and legs).
GWARNING
Modifications to electronic components,
their software as well as wiring can impair
their function and/or the function of other
networked components. In particular, sys-
tems relevant to safety could also be affec-
ted. As a result, these may no longer func-
tion as intended and/or jeopardize the oper-
ating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
Function restrictions
For safety reasons, some functions are restric-ted or unavailable while the vehicle is inmotion. You will notice this, for example,because either you will not be able to selectcertain menu items or a message will appearto this effect.
