Observe the important safety notes on Distance Pilot DISTRONIC (Y page 184).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Pilot is
then switched to passive. Distance Pilot
DISTRONIC remains active.

Road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible.
The vehicle level may change visibly if you park
the vehicle and the outside temperature
changes. If the temperature drops, the vehicle
level lowers; with an increase in temperature,
the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, e.g. after the vehicle has
been stationary for a long period, the engine
must be running. For safety reasons, the vehicle
is only lowered when the doors are closed. Low-
ering is interrupted if a door is opened; it con-
tinues once the door has been closed.

(Y page 176). G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches. G
WARNING
When driving at a raised vehicle level, the driv- ing characteristics may be significantly affec-ted by the vehicle's raised centre of gravity.
The vehicle may be more liable to tip when
cornering, for example. There is a risk of an
accident. 192

Parking Assist PARKTRONIC
Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or objects in range while manoeuvring and parking.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic car
wash, a lorry's compressed-air brakes or a
pneumatic drill, could cause PARKTRONIC to
malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC measures the minimum detection range to an obstacle
from the bumper, not the ball coupling.
Parking Assist PARKTRONIC is deactivated for
the rear area when you establish an electrical
connection between your vehicle and a trailer.
Parking Assist PARKTRONIC is activated auto-
matically when you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 18 km/h. It is reactivated at lower
speeds. Range of the sensors General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R below the detection range, e.g. persons, ani-
mals or objects
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles :
Sensors in the front bumper, left-hand side
(example)
The sensors must be free of dirt, ice and slush.
Otherwise, they may not function correctly.

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.

Parking Pilot no longer supports you with steer-
ing interventions and brake applications. When
Parking Pilot is finished, 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 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.
X Start the engine.
X Release the electric parking brake.
X Switch on the turn signal in the direction you
will drive out of the parking space. 206
