of their lane
R other vehicles changin glane
R narrow vehicles
R obstructions and stationary vehicles
R crossin gvehicles
In such situations, brake if necessary.

Cornering, entering and exiting abend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.

At speedsofm ore than 60 km/h ,Steering

Important safety notes
If you fail to adapt yourd riving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotc an neither reduce the risk of
an accident nor override the lawsofp hysics.
It cannot take into account road, weather or
traffic conditions. DISTRONIC PLUS with
Steering Assist and Stop&Go Pilotiso nly an

the vehicle in front, for vehicle speed,f or
braking in good time, and for staying in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotd oes not detect road and traf-
fic conditions and does not detect all road
users. If you are following avehicle which is
driving towards the edge of the carriageway,
yourv ehicle could come into contact with the
kerb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that
are directly next to yourv ehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g.
after intentionally driving over alane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotc annot continuousl ykeep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it
does not leave the lane.
The support offered by the system may be
impaired if:
R
there is poor visibility, e.g. due to insuffi-
cient 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 windscree nisdirty, misted up, dam-
aged or covered, for instance by asticker,

R no, or several ,unclea rlane markings are
present for one lane, e.g. in aconstruction
area
R the lane markings are worn away, dark or
covered 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
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highlyv ariable shade conditions
on the road
The system is switched to passive and no lon-
ger assists you by performing steering inter-

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 asuitable parking space. Active
steering intervention and brake application
can assist you during parking. You may also
use PARKTRONIC (Y page 235).
i The active braking application is only
available on vehicles with automatic trans- mission.
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
objectsa re in the manoeuvring range. When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. 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
obstacles such as kerbs slowly and not at a
sharp 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 prohibitions
R in front of drivewaysore ntrances and exits
R unsuitable surfaces Driving systems

operational at speeds of up to approximately 35 km/h .While in operation, the system inde-
pendently locate sand measures parking

i Note that Active Parking Assist cannot
measure the size of aparking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When driving at speeds below 30 km/h, you
will see parking symbol ;asas tatus indi-
cator in the instrument cluster. When apark-

towards the right or the left also appears.
Active Parking Assist only display sparking

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 untilyou confirm the use of Active Parking Assist
by pressing the abutton on the multi-
function steerin gwheel. The system auto-
matically determines whether the parking
space is parallel or at right angles to the direc-
tion of travel.
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 maway from it. Parking G
WARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
R there is amalfunction in the system or in
