X Always observe the warning messages dis-
played by PARKTRONIC (Y page 199).
Parking tips: R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should can- cel the parking procedure with Active Park-
ing Assist.
R You can also select preselect transmission
position D. The vehicle redirects and does
not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A sen- sible parking position can no longer be ach-
ieved from this position.
Exiting a parking space In order that Active Parking Assist can sup-
port you when exiting the parking space:
R the border of the parking space must be
high enough at the front and the rear. A
curb is too small, for example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvering into the park-
ing space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
i If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst
the vehicle exits the parking space. You are
responsible for braking in good time.
Active Parking Assist can only assist you with exiting a parking space if you have parked the Driving systems

General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break. Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the length of the journey is less than
approximately 30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h)
R if you are driving with the DISTRONIC PLUS
Steering Assist activated
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or to take a break
Displaying the attention level Driving systems
213Driving and parking Z

You can have current status information dis-
played in the assistance menu (Y page 235)
of the on-board computer.
X Select the Assistance display for ATTEN-
TION ASSIST using the on-board computer
(Y page 235).
The following information is displayed:
R length of the journey since the last break.
R the attention level determined by ATTEN-
TION ASSIST, displayed in a bar display in
five levels from high to low.
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System Suspended System Suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 236).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
Sensitive selected: the sensitivity is set
higher. The attention level detected by Atten- tion Assist is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the À symbol and OFF appear in the multi-
function display in the assistance display
when the engine is running.
When ATTENTION ASSIST has been deactiva- ted, it is automatically reactivated after the
engine has been stopped. The sensitivity
selected corresponds to the last selection
activated (standard/sensitive). Warning in the multifunction display If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist:
Attention Assist:
Take a Break! Take a Break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X If necessary, take a break.
X Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing lap-
ses in concentration.
Vehicles with COMAND: if a warning is
issued in the multifunction display, a service
station search is performed in COMAND. You
can select a service station and navigation to this service station will then begin. This func- tion can be activated and deactivated in
COMAND. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 214) and Lane Keeping
Assist (Y page 216).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will also receive an optical and audible collision 214
Driving systemsDriving and parking

warning. Blind Spot Assist uses sensors in the
rear bumper for monitoring purposes.
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
i USA only:
This device has been approved by the FCC as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors
R there is poor visibility, e.g. due to fog, heavy
rain, snow or spray
R there are narrow vehicles, e.g. motorcycles
or bicycles
R the road has very wide lanes
R the road has narrow lanes R
you are not driving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated. If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if there are vehicles driving at the
inner edge of their lanes.
Due to the nature of the system:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
The two radar sensors for Blind Spot Assist
are integrated into the sides of the rear
bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing a severe impact or in the event of dam- age to the bumpers, have the function of the
sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly. Driving systems
