in the middle of their lane. The distance to the
vehicle in fron twill be too short.
R Other vehicles changing lane: DISTRONIC

yet. The distance to this vehicle will be too
short.
R Narro wvehicles: DISTRONIC PLUS has not

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

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

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
