that are parallel to the direction of travel and
at least 39.5 in (1.0 m) longer than your vehi-
cle R
that are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider than
your vehicle
i Note that Parking Pilot cannot measure the
length of a parking space if it is at right angles
to the direction of travel. You will need to
judge whether your vehicle will fit into the
parking space.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol D as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. Park-
ing Pilot only displays parking spaces on the
front-passenger side as standard. Parking
spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain activated until you confirm the
use of Parking Pilot by pressing the v button
on the multifunction steering wheel. The system
automatically determines whether the parking
space is parallel or at right-angles to the direc-
tion 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.

G WARNING
If you leave the vehicle when it is only being
braked by Parking Pilot, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with. R
the battery is disconnected. R
the vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.
i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically whilst the vehicle is parking. You are respon-
sible for braking in good time. X

Driving and parking

As soon as the parking procedure is complete,
the Parking Pilot Ended message appears in
the multifunction display and a warning tone
sounds. The vehicle is now parked.
The vehicle is kept stationary without the driver
having to depress the brake pedal. The braking
effect is canceled when you depress the accel-
erator pedal.
Parking Pilot no longer supports you with steer-
ing interventions and brake applications. When
Parking Pilot is ended, you must steer and brake
again yourself. Parking Assist PARKTRONIC is
still available.
Parking tips: R
The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Parking Pilot 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 abort the parking procedure with Park-
ing Pilot. R
You can also select preselect transmission
position D . The vehicle redirects and does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. A sensi-
ble parking posi tion can no longer be ach-
i
eved from this position.
Exiting a parking space In order for Parking Pilot to support you when
exiting the parking space: R
you need to have parked using Parking Pilot. R
the border of the parking space must be high
enough at the front and the rear. A curb stone
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 maneuvered into the parking
space. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available .
Parkin g Pilo t can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel using Parking
Pilot. i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically
whilst the vehicle is exiting the parking space.
You are responsible for braking in good time. X

Confirm the message by pressing the v
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 ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
Vehicles with the COMAND multimedia sys-
tem: if a warning is output in the multifunction
display, a service station search is performed in
the multimedia system. You can select a service
station and navigation to this service station will
then begin. This function can be activated or
deactivated in the multimedia system; see the
Digital Operator's Manual.
Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist ( Y
page 171) and Lane Keeping
Assist ( Y
page 172).
Blind Spot Assist
General notes Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you will
also receive an optical and audible warning.
Blind Spot Assist supports you from a speed of
approximately 20 mph (30 km/h).
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 tam-
per 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.
Radar sensors The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. 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 radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may no longer work properly.
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 or snow R
a narrow vehicle traveling in front, e.g. a
motorbike or bicycle 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 other road boundaries
Vehicles in the monitoring range are then not
indicated.Driving systems 171
Driving and parking Z

Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to it.
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 driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
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
warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
Warning display
C
Warning display
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 C in the exterior mirrors lights up yellow
at speeds of up to 20 mph (30 km/h). At speeds
above 20 mph (30 km/h), the indicator lamp
goes out and Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the correspond-
ing 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
7 mph (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 ambi-
ent light.
Collision warning If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp C flashes. If the turn
signal remains on, vehicles detected are indica-
ted by the flashing of red warning lamp C .
There are no further warning tones.
Switching on Blind Spot Assist X
Make sure that Blind Spot Assist is activated
in the on-board computer ( Y
page 183).X
Turn the SmartKey to position 2 in the ignition
lock.
Warning lamps C in the exterior mirrors light
up red for approximately 1.5 seconds and
then turn yellow.
Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era C which is attached behind the top of the
windshield. Active Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.172

Important safety notes
G WAR NING
Lane Kee pin g Assist may not always clearly
recognize lane markings.
In th is case, Lane Kee pin g Assist may:R
give an unnecessary warning R
not give a warning
There is a risk of an acc iden t.
Always pay particular attention to the traff ic
situation and stay in lane, in particular if
warned by Lane Kee pin g Assist.
G WAR NING
The Lane Kee pin g Assist warning does not
return the veh icle to the original lane. There is
a risk of an acc iden t.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Kee p-
ing Assist.
If you fail to adapt your driv ing style, Lane Kee p-
ing Assist can neither reduce the risk of an acc i-
dent nor overr ide the laws of physics. Lane
Kee pin g Assist cannot take into account the
road, traff ic and weather conditions. Lane Kee p-
ing Assist is merely an aid. You are respon sible
for the dist ance to the veh icle in front, for veh i-
cle spee d, for braking in good time and for stay-
ing in your lane.
The Lane Kee pin g Assist does not keep the veh i-
cle in the lane.
The system may be impaired or may not function
if: R
there is poor vis ibilit y, e.g. due to insuff icie nt
illumi nation of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other veh icle s (e.g. if
the road surface is wet)R
the win dshield is dirt y, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas wit h road construction
work R
the lane markings are worn away, dark or cov-
er ed up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and win dingR
there are highly variable shade conditions on
the roadway
Switching on Lane Keeping Assist X
Swit ch on Active Lane Keeping Assist using
the on-board computer; to do so, select
Standard or Adaptive ( Y
page 183).
If you drive at spee ds above 40 mph
(60 km/ h) and lane markings are detected,
the lines in the assistance graphics display
( Y
page 182) are shown in green. Lane Keep-
ing Assist is ready for use.
If Standard is selected, no warning vibration
occurs if: R
you have switched on the turn signal. In this
event, the warnings are suppressed for a cer-
tain period of time. R
a driving safety system intervenes, e.g. ABS,
BAS or ESP ®
.
When Adaptive
is selected, no warning vibra-
tion occurs if: R
you have switched on the turn signal. In this
event, the warnings are suppressed for a cer-
tain period of time. R
a driving safety system intervenes, e.g. ABS,
BAS or ESP ®
. R
you accelerate hard, e.g. kickdown. R
you brake hard. R
you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly. R
you cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if: R
you approach the outer lane marking on a
bend. R
the road has very wide lanes, e.g. a highway. R
the system detects solid lane markings.
The warning vibration occurs later if: R
the road has narrow lanes. R
you cut the corner on a bend.Driving systems 173
