Problems with PARKTRONIC
Problem Possible causes/consequences and
M
MSolutions Only the red segments
in the PARKTRONIC
warning displays are lit.
You also hear a warning
tone for approximately
two seconds.
PARKTRONIC is deacti-
vated after approx-
imately five seconds,
and the indicator lamp
in the PARKTRONIC
button lights up. PARKTRONIC has malfunctioned and has switched off.
X
If problems persist, have PARKTRONIC checked at a qualified
specialist workshop. Only the red segments
in the PARKTRONIC
warning displays are lit.
PARKTRONIC is deacti-
vated after approx-
imately five seconds. The PARKTRONIC sensors are dirty or there is interference.
X
Clean the PARKTRONIC sensors (Y page 321).
X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X
See if PARKTRONIC functions in a different location. Active Parking Assist
Important safety notes Active Parking Assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
A suitable parking space is indicated by the
parking symbol. Active steering intervention
can assist you during parking. You may also
use PARKTRONIC (Y page 188). When PARK-
TRONIC is switched off, Active Parking Assist
is also unavailable. G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommend parking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited, driveways, unsuitable surfaces, etc.
Active Parking Assist measures the parking
space as you drive past it. Any later changes to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could
cause an accident and injure yourself and oth-
ers.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
WARNING
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking 192
Driving systemsDriving and parking

procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations. G
WARNING
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehicle
will also take you onto sections of the oncom-
ing lane during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 189 )warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be cancelled. R
when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergency spare
wheel are fitted, you should not use Active
Parking Assist here either.
R make sure that the tyre pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. It may be the case that Active
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 kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be cancelled.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Detecting parking spaces Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 30 km/h, you will see
parking symbol as a status indicator in the
instrument cluster. Active Parking Assist only
displays parking spaces on the front-
passenger side as standard. Parking spaces
on the driver's side are displayed as soon as Driving systems
193Driving and parking Z

the turn signal on the driver's side is activa-
ted. To park on the driver's side, you must
leave the driver's side turn signal switched
on. This must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the abutton on the multi-
function steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. Example: detected parking space
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 1.5 m wide
R that are at least 1.3 m longer than your
vehicle
A parking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.
Parking G
WARNING
PARKTRONIC and Active Parking Assist are
merely parking aids and may not detect all
obstacles. They do not relieve you of the
responsibility of paying attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could, otherwise, endanger
yourself and others. G
WARNING
When parking, you need to make sure that no
obstacles are located in the vicinity of the
vehicle during the entire operation. Active
Parking Assist does not relieve you of the
responsibility of paying attention. It merely
aids you by intervening actively in the steer-
ing.
To stop the vehicle or avoid an accident you
need to apply the brakes yourself.

Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break. G
WARNING
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not a substitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey-related parameters, e.g. time of
day, length of journey
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the sur-
face 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 slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND Online
or making a telephone call with COMAND
Online
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed Driving systems

On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, 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 lap-
ses in concentration.
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey 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. Speed Limit Assist
Important safety notes Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does not detect any traffic
signs, the speed limit from the digital road
map is taken and shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windscreen.
:
Speed Limit Assist camera G
WARNING
Speed Limit Assist is only an aid and may
detect speed limit signs incorrectly or not at
all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R the traffic signs are covered, for instance
by dirt, snow or trees.
R the traffic signs are poorly illuminated.
R there are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads.
Traffic signs always have priority over the
Speed Limit Assist display. Speed Limit Assist
cannot detect road and traffic conditions. It is
not a substitute for attentive driving. 202
