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
201Driving and parking Z

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 aparking
space being measured inaccurately
R pay attention to the PARKTRONIC
(Y page 199) warning messages during the
parking procedure
R you can intervene in the steerin gprocedure to
correc titata ny time. Active Parking Assist
will then be cancelled.
R when transportin gaload which protrudes
from your vehicle, you should not use Active
Parking Assist
R never use Active Parking Assist when snow
chains are fitted
R make sure that the tyre pressures are always
correct. This has adirect influenc eonthe
parking characteristics of the vehicle.
Use Active Parking Assist 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 Object
slocated 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 procedure is cal- culated, e.g. overhangin gloads, tail sections or
loading ramps of goods vehicles. G
WARNING
If there are object sabove the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in frontoft hese
objects
This could cause acollision. There is arisk of
an accident. If object
sare located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(Y page 198).
Active Parking Assist does not assist you park-
ing 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 alow
obstacle such as alow kerb
R you forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
R the parking space is on akerb
R the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. atree, apost or atrailer :
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional 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. 202
