Tips for driving with DISTRONIC PLUS
General notes
Pay particular attention in the following traffic
situations:
RCornering, going into and coming out of a
bend
RVehicles traveling on a different line
ROther vehicles changing lanes
RNarrow vehicles
RObstructions and stationary vehicles
RCrossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle may
brake unexpectedly or late.
Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles trav-
eling on a different line. The distance to the
vehicle in front will be too short.
Other vehicles changing lanes
DISTRONIC PLUS has not detected the vehicle
cutting in yet. The distance to this vehicle will be
too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the vehi-
cle in front on the edge of the road, because of
its narrow width. The distance to the vehicle in
front will be too short.

cle could come into contact with the curb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as building site huts on the lane
or projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle
back to the lane. In such cases, you must steerthe vehicle yourself to ensure that it does not
leave the lane.
The support provided by the system can be
impaired if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rno, or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
The system is switched to passive and no longer
assists you by performing steering interventions if:
Ryou actively change lanes
Ryou switch on the turn signal
Rtake your hands off the steering wheel or do
not steer for a prolonged period of time
iAfter you have finished changing lanes,
Steering Assist and Stop&Go Pilot are auto-
matically active again. DISTRONIC PLUS Steering Assist does not pro-
vide assistance:
Ron very sharp corners
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes for DISTRONIC PLUS (
Ypage 147).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
l

atest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Assist
and Stop&Go Pilot are switched to passive.
DISTRONIC PLUS remains active.

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. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking. You may also use PARKTRONIC
(
Ypage 158).
iThe active braking application is only avail-
able on vehicles with automatic transmission.
Important safety notes
Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk 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 curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for park-
ing, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.

RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 159) warning messages during the
parking procedure.
RYou can intervene in the steering procedure
to correct it at any time. Active Parking Assist
will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use Active
Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Active Parking Assist for parking spaces:
Rparallel or at right angles to the direction of
travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g. not
on the sidewalk.
Detecting parking spaces
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 procedure is cal-
culated, e.g. overhanging loads, tail sections or
loading ramps of goods vehicles.
GWARNING
If there are objects above the detection range:
RActive Park Assist may steer too early
Rthe vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(
Ypage 158). Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou park forwards
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
Example: detected parking space
:
Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Active Parking Assist is switched on automati-
cally when driving forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the sys-
tem independently locates and measures park-
ing spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and
at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel and
at least 39.5 in (1.0 m)longer than your vehi-
cle
Rthat are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider than
your vehicle

Driving and parking

iNote that Active Parking Assist cannot
measure the length of a parking space if it is at
right angles to the direction of travel. You will
need to judge whether your vehicle will fit into
the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. By
default, Active Parking Assist only displays park-
ing spaces on the front-passenger side. Parking spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain switched on until you acknowl-
edge the use of Active Parking Assist by press-
ing the abutton on the multifunction steer-
ing wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 50 ft
(15 m) away from it.
Parking
GWARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.

Parking tips:
RThe 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
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 curb. If necessary,
you should cancel the parking procedure with
Active Parking Assist.
RYou can also select preselect transmission
position D. The vehicle redirects and does not
drive as far into the parking sp ace. Sh
ould a
gear be changed too early, the parking pro-
cedure will be canceled. A sensible parking
position can no longer be achieved from this
position.
Exiting a parking space
In order that Active Parking Assist can support
you when exiting the parking space:
Rthe border of the parking space must be high enough at the front and the rear. A curb is too
small, for example.
Rthe 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 maneuvering into the parking
space.
Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available .
iVehicles with automatic transmission:
If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are
responsible for braking in good time. Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
