Problems with Parking Assist PARKTRONIC
Problem
Possible causes/consequences and
M
MSolutions Only the red segments in
the Parking Assist
PARKTRONIC warning
displays are lit. You also
hear a warning tone for
approximately two sec-
onds.
Parking Assist
PARKTRONIC is then
deactivated and the indi-
cator lamp on the
PARKTRONIC button
lights up. Parking Assist PARKTRONIC is malfunctioning and has been deacti-
vated.
X If problems persist, have Parking Assist PARKTRONIC checked at a
qualified specialist workshop. Only the red segments in
the Parking Assist
PARKTRONIC warning
displays are lit. Parking
Assist PARKTRONIC is
then deactivated. The Parking Assist PARKTRONIC sensors are dirty or malfunctioning.
X Clean the Parking Assist PARKTRONIC sensors (Y page 289).
X Switch the ignition back on. The problem may be caused by an external source of radio or ultra-
sound waves.
X Check to see if Parking Assist PARKTRONIC functions in a different
location. 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 and when exiting a parking space. Park- ing Assist PARKTRONIC is also available
(Y page 177).
i The active braking application is only avail-
able on vehicles with automatic transmission.
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 Parking Pilot 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 also display spaces not suita- ble 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 180
Driving systemsDriving and parking

Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
might be identified or measured incorrectly
R parking spaces that are partially occupied by
trailer drawbars 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 Parking Assist
PARKTRONIC warning messages
(Y page 178) during the parking procedure
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 should 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
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical
connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa- ble. Parking Assist PARKTRONIC is deactivated
for the rear area.
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. G
WARNING
If there are objects above the detection range:
R Parking Pilot may steer in 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 Parking Pilot.
Further information on the detection range
(Y page 177).
Parking Pilot does not assist you parking in
spaces at right angles 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 or at right angles 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. Driving systems
181Driving and parking Z

Parking Pilot will detect only parking spaces
which are:
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 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 in the park-
ing 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 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 Vehicles with automatic transmission:
If Parking Assist PARKTRONIC detects obsta-
cles, Parking Pilot brakes automatically whilst
the vehicle is parking. You are responsible for
braking in good time.

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 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 abort the parking procedure with Park-
ing 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 that Parking Pilot can 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 kerb stoneis 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 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 using the Park-
ing Pilot
i Vehicles with automatic transmission:
If Parking Assist PARKTRONIC detects obsta-
cles, 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.

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect 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 in the following situations:
R the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in case of strong side winds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
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 and starts assessing your tiredness again when you continue your
journey if:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break Displaying the attention level
You can have current status information dis-
played in the Assistance menu (Y
page 208) of
the on-board computer.
X Select the assistance graphic display for
ATTENTION ASSIST using the on-board com-
puter (Y page 208).
The following information is displayed: R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST( Attention level

bar display in five levels from high to low
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a warn-
ing, the System suspended System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below 60 km/h or above 200 km/h.
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 209).
The system determines the attention level of
the driver depending on the setting selected:
Standard Standard selected: the sensitivity with which
the system determines the attention level is set to normal.
Sensitive 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
é symbol appears in the multifunction dis-
play in the assistance graphic display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been switched off. The sensitivity selected Driving systems
