Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in fronta nd behind it and the conditions of
the location. It may be the case tha tActive
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 .Ifnecessary, you should cancel the parking procedure with Active
Parking Assist.
R You can also engage forward gear
prematurely. 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
sensible parking position can no longer be
achieved from this position.
Exiting aparking space In order that Active Parking Assist can
support you whe
nyou exit 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 parking space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.

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
ATTENTION ASSIST detects typical indicators
of fatigue 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.T
he 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
surface 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
active steer 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
continue 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 You can have current status information
displayed in the assistance menu
(Y
page 240) of the on-board computer.
X Select the Assistance display for Attention
Assist using the on-board computer
(Y page 240).
The following information is displayed:
R length of the journey since the last break.
R the attention level determined by
ATTENTION 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 a warning cannot be
issued, the System Passive 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). 220
Driving systemsDriving and parking

Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 242).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determine sthe attention
level is set to normal.
Sensitive selected: the sensitivity is set
higher. The attention level detected by
Attention Assist is adapted accordingly and
the driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
0002 symbol and OFF appearint he
multifunction display in the assistance
display when the engine is running.
When ATTENTION ASSIST has been
deactivated, 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
concentration are detected, a warning
appears in the multifunction display:
Attention Assist: Take a Break! In addition to the message shown in the
multifunction display, you will then hear a
warning tone.
X If necessary, take a break.
X Confirm the message by pressing the
000B 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 and ATTENTION ASSIST
still detects increasing lapses in
concentration, 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
lapses in concentration. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 221) and Lane Keeping
Assist (Y page 223).
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 exterio rmirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding tur nsignal to change lanes,
you will also receive a visual and audible
collision 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 the minthe 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
carefully, 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 "VehicularR adar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering Driving systems
221Driving and parking Z

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 dirt on the sensors or anything else
covering the sensors
R poor visibility, e.g .due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or
bicycles
R the road has very wide lanes
R the road has narrow lanes
R you are no tdriving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated. Example
:Coupe
Blind Spot Assist monitors the area up to
10 ft (3 m) behind your vehicle and directly
next to your vehicle, as shown in the diagram.
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
driving 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
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the sensors checked at a qualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display 0002
Yellow indicator lamp/red warning lamp
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h) .Vehicles in
the monitoring range are then not indicated.
When Blind Spot Assist is activated, indicator
lamp 0002in the exterior mirrors lights up
yellow at speeds of up to 20 mph (30k m/h).
At speeds above 20 mph (30 km/h), the
indicator lamp goes out and Blind Spot Assist

Driving systemsDriving and parking

If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp
0002on the
corresponding side lights up red. This warning
is always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp 0002flashes. If
the turn signal remains on, vehicles detected
are indicated by the flashing of red warning
lamp 0002.There are no further warning tones.
