Problems with PARKTRONIC
Problem
Possible causes/consequences and
M
MSolutions Only the red segments in
the PARKTRONIC warn-
ing displaysa re lit. You
also hear awarning tone
for approximately two
seconds.
PARKTRONIC is then
deactivated and the indi-
cator lamp on the
PARKTRONIC button
lights up. PARKTRONIC has malfunctioned and has been deactivated.
X If problems persist, have PARKTRONIC checked at aqualified spe-
cialist workshop. Only the red segments in
the PARKTRONIC warn-
ing displaysa re lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X
Clean the PARKTRONIC sensors (Y page 330).
X Switch the ignition back on. The problem may be caused by an external source of radio or ultra-
sound waves.
X See if PARKTRONIC functions in adifferent location. Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk 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 asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems

i Not
ethat Activ eParking Assist cannot

the parking space.
When drivin gatspeeds below 30 km/h, you will
see parking symbol ;asas tatus indicator in
the instrumen tcluster. When aparking space
has been detected, an arrow towards the right or the left also appears. Activ eParking Assist 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 onthe driver's side is activated. When parking on
the driver's side, this must remain activated
until you confirm the use of Activ eParking Assist
by pressing the abutton on the multifunc-
tion steerin gwheel. The system automatically
determines whether the parking space is paral-
lel or at right angles to the direction of travel.
Ap arking space is displayed while you are driv-
ing past it, and until you are approximately 15 m
away fro mit.

WARNING
If you leave the vehicle when it is only being
braked by Activ eParking Assist it could roll

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 Active Parking Assist
guidesy ou too far into aparking 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 withActive Parking Assist.
R Vehicles with automatic transmission:
you can also preselect transmission position
D.T he vehicle redirects and does not drive as
far into the parking space. Should the trans-
mission change take place too early,t he park-
ing procedure will be cancelled. Asensible
parking position can no longer be achieved
from this position.
R Vehicles with manual transmission: you
can also engage forward gear prematurely.
The vehicle redirects and does not drive as far
into the parking space. Should the transmis-
sion change take place too early,t he parking
procedure will be cancelled. Asensible park-
ing position can no longer be achieved from
this position.
Exiting aparking space In order that Active Parking Assist can support
you when exiting the parking space:
R the border of the parking space must be high
enough at the front and the rear. Akerb 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 manoeuvred into the parking
space.
R am anoeuvring distance of at least 1.0 mmust
be available.

Important safety notes G
WARNING
Lane Keeping Assist cannot alway sclearly
identify lane markings.
In these cases, Lane Keeping Assist may:
R give an unnecessary warning
R not give awarning
There is arisk 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 ar isk 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 asticker, in the
vicinit yofthe camera R
no or several, unclear lane markings are pres-
ent for one lane, e.g. in aconstruction area
R the lane markings are worn away,d ark 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
