Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking. Parking Assist PARKTRONIC is also
available (Y page 201).
Important safety notes Parking Pilot is only an aid. It is not a substitute
for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that no
persons, animals or objects are in the manoeu-
vring range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable. G
WARNING
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.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tyres.
Parking Pilot may show parking spaces which
are not suitable for parking, e.g.:
R in a zone where parking or stopping is pro-
hibited
R in front of driveways or entrances and exits
R on unsuitable surfaces
Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
may not be identified or may be measured
incorrectly
R parking spaces in front of parked trailers, the
trailer drawbars of which protrude into the parking space, might not be identified as such
or be measured incorrectly
R snowfall or heavy rain may lead to a parking
space being measured inaccurately
R pay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure (Y page 201)
R you can intervene in the steering procedure to
correct it at any time. Parking Pilot will then be cancelled.
R when transporting a load that protrudes from
your vehicle, you must not use Parking Pilot
R never use Parking Pilot when snow chains are
fitted
R Make sure that the tyre pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle
Use Parking Pilot for parking spaces that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, tail sections or load-
ing ramps of goods vehicles. Parking Pilot may
therefore guide you into the parking space too
early. G
WARNING
If there are objects above the detection range:
R Active Park Assist may steer too early
R the 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 Active Parking
Assist.
Further information on the detection range
(Y page 201). 204
Driving systemsDriving and parking

Parking Pilot does not assist you parking in
spaces at a right angle to the direction of travel
if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward-park
Parking Pilot does not assist you parking in
spaces parallel with or at a right angle to the
direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as being
blocked, such as by foliage or grass paving
blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer :
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Parking Pilot is activated automatically when
driving forwards. The system is operational at
speeds of up to approximately 35 km/h. While
in operation, the system independently locates
and measures parking spaces on both sides of
the vehicle.
Parking Pilot will detect only parking spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel and
are at least 1.5 m wide
R that are parallel to the direction of travel and
at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your vehi-
cle
i Note that Parking Pilot PARKTRONIC cannot
measure the depth of parking spaces if they
are at right angles to the direction of travel. You will need to judge whether your vehicle
will fit in the parking space.
When driving at speeds below 30 km/h, you will
see parking symbol ;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. Parking Pilot displays only
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 a button on the multifunction steering
wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 15 m
away from it.

WARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist 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 being parked. You are
responsible for braking in good time. Driving systems

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 of 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 kerb. If necessary, you
should cancel the parking procedure with
Parking Pilot.
R You can also preselect transmission position
D. The vehicle redirects and does not drive as
far into the parking space. Should the trans-
mission change take place too early, the park-
ing procedure will be cancelled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space In order for Parking Pilot to assist you:
R the border of the parking space must be high
enough at the front and the rear. A kerb, for
example, is too small.
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 manoeuvred into the parking
space.
R a manoeuvring distance of at least 1.0 mmust
be available.
Parking Pilot can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel.
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.

Lane Keeping Assist
General notes
:
Lane Keeping Assist camera
Lane Keeping Assist monitors the area in front of
your vehicle by means of camera :at the top of
the windscreen. Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally.
This function is available in a speed range
between 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 through the steering
wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep in lane, especially if Lane
Keeping Assist alerts you. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you. If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. Lane Keeping
Assist is only an aid. You are responsible for the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function if:
R there is poor visibility, e.g. due to insufficient
illumination 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 vehicles (e.g. if
the road surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered 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 winding
R there are highly variable shade conditions on
the road

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 detects 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 motorway
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 Assistance Plus package
General notes The Driving Assistance Plus package consists of
Distance Pilot DISTRONIC (Y page 184), Active
Blind Spot Assist (Y page 222) and Active Lane
Keeping Assist (Y page 224).
Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not directly
visible to the driver with two lateral, rear-facing
radar sensors. A warning lamp lights up in the
exterior mirrors and draws your attention to
vehicles detected in the monitored area. If you then switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible collision warning. If a risk of side impact
is detected, corrective braking may help you
avoid a collision. Active Blind Spot Assist eval-
uates the free space in the direction of travel
and to the side before making a course-correct- ing brake application. For this, Active Blind Spot
Assist uses the forward-facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
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 pay careful attention to the traffic sit-
uation and maintain a safe distance at the side of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The sensors
must not be covered, e.g. by cycle racks or over-
hanging loads. Following an accident or in the
event of damage to the bumpers, have the func- tion of the radar sensors checked at a qualifiedspecialist workshop. Active Blind Spot Assist
might otherwise no longer function properly.
Monitoring range G
WARNING
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 dis-
tance to the side for other traffic or obstacles. 222
Driving systemsDriving and pa
rking

Active Blind Spot Assist monitors the area up to
3.0 m behi nd your vehicle and directly next to
your vehicle, as shown in the diagram.
In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
reliably indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
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 there are vehicles at the edge of their
lane.
On very wide lanes, vehicles in the lane next to
your vehicle may not be displayed if the vehicles
are too far away.
The nature of the system may result in the fol-
lowing:
R Warnings may be issued in error when you are
driving close to crash barriers or similar solid boundaries
R Warnings may be interrupted when you are
driving alongside particularly long vehicles,
for example lorries, for a prolonged time Indicator and warning display
:
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not operational at
speeds of below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If Active Blind Spot Assist is switched on, indi-
cator lamp :in the exterior mirrors lights up
yellow up to a speed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out and Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above 30 km/h, warning
lamp :on the corresponding side lights up red.
This warning lamp always lights up when a vehi- cle enters the blind spot monitoring range from
behind or from the side. When you overtake a
vehicle with a difference in speed of less than
12 km/h, a delayed warning occurs.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is not
operational.
The brightness of the indicator/warning lamps
is adjusted automatically according to the
brightness of the surroundings.
Visual and acoustic collision warning If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision
warning. You then hear a double warning tone
and red warning lamp :flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of red warning lamp :. No fur-
ther warning tones are issued.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a side impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid a collision. Driving systems
223Driving and parking Z

G
WARNING
A course-correcting brake application cannot 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 appli-
cation. Always maintain a safe distance at the sides.
If a course-correcting brake application occurs, red warning lamp :flashes in the exterior mir-
ror and a dual warning tone sounds. In addition, display underlining the danger of a side collision
appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at any time if you steer slightly in the opposite
direction or accelerate.
The course-correcting brake application is avail-
able in the speed range between 30 km/h and
200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur in the following situations:
R there are vehicles or obstacles, e.g. crash
barriers, close to both sides of your vehicle
R a vehicle approaches too closely on the side
R you have adopted a sporty driving style with
high cornering speeds
R you brake or accelerate significantly
R a driving safety system engages, such as

Active Lane Keeping Assist General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera :at the top of the windscreen. Various
different areas to the front, rear and side of your vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available within a speed range
between 60 km/h and 200 km/h.
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must be
operational. 224
