some cases, it may also lead you across or
onto the curb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist. R
You can also select preselect transmission
position D . The vehicle redirects and does
not drive as far into the parking space.
Should the gear change occur too soon to
achieve a sensible parking position, the
parking procedure will be aborted.
Exiting a parking space In order that Active Parking Assist can sup-
port you when you exit the parking space: R
you need to have parked using Active Park-
ing Assist. R
the border of the parking space must be
high enough at the front and the rear. A
curb 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 maneuvered into the park-
ing space. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available. X
Start the engine. X
Release the electric parking brake. X
Switch on the turn signal in the direction
you are pulling away. X
Shift the transmission to position D or R .

continuous warning tone, if not before. X
Shift the transmission to position D or R as
required while the vehicle is stationary.
Active Parking Assist immediately steers in
the other direction.
i You will achieve the best results by wait-
ing for the steering procedure to complete
before pulling away.
If you back up after activation, the steering
wheel is moved to the straight-ahead posi-
tion. X
Drive forwards or back up the vehicle, being
ready to brake at all times. X
Stop as soon as PARKTRONIC sounds the
continuous warning tone, if not before. X
Drive forwards and back up as prompted by
the PARKTRONIC warning displays, several
times if necessary.
Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and
the Park Assist Finished message
appears in the multifunction display. You will
then have to steer and merge into traffic on
your own. PARKTRONIC is still available. You
can take over the steering, before the vehicle
has exited the parking space completely. This
is useful, for example when you recognize
that it is already possible to pull out of the

Im portant safety notes
G WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may: R
give an unnecessary warning R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
G WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely 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 your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane. The system may be impaired or may not func-
tion 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 reflections (e.g. when the road
surface is wet) R
the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work 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
d e tected 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 strong shadows cast on the road

Active Blind Spot Assist
General notes
Active Blin d Spo t Assist mon it ors the areas
on either side of the vehicle that are not
dire ct ly vis ible to the driver with two lateral,
rear-facing radar sensors. A warning lamp
lights up in the exterior mirrors and draws your attention to vehicles detected in the
mon it ored area. If you then switch on the cor-
respon din g turn signal to change lanes, you
will also receive a visual and audible co llisio n
warning. If a risk of lateral co llisio n is detec-
te d, correct ive braking may help you avoid a
co llisio n. Before a course-correcting brake
applic ation, Acti ve Blind Spo t Assist evalu-
ates the space in the dire ction of travel and at
the sides of the vehicle. For this, Acti ve Blind
Spot Assist uses the forward-facing radar
sensors.
Acti ve Blind Spo t Assist supports you from a
speed of approximately 20 mph (30 km/h).

Indicator and warning display
C
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at
speeds below approximately 20 mph
(30 km/h). Vehicles in the monitoring range
are then not indicated.
When Active Blind Spot Assist is activated,
indicator lamp C in the exterior mirrors lights
up yellow at speeds of up to 20 mph
(30 km/h). At speeds above 20 mph
(30 km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above approximately 20 mph
(30 km/h), warning lamp C on the corre-
sponding side lights up red. This warning lamp
always lights up when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle
with a difference in speed of less than 7 mph
(12 km/h), a delayed warning occurs.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
not operational.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the brightness of the surroundings.
Visual and acoustic collision warning
If you switch on the turn signals to change
lanes and a vehicle is detected in the side
monitoring range, you receive a visual and
acoustic collision warning. You then hear a
double warning tone and red warning lamp C
flas hes. If the turn signal remains on, detec-
ted vehicles are indicated by the flashing of red warning lamp C . There are no further
warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
G WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blin d Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application
occurs, red warning lamp C flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display D underlining
the danger of a side collision appears in the
multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-
correcting brake application may be interrup-
ted at any time if you steer slightly in the
opposite direction or accelerate.
The course-correcting brake application is
available in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).250

If a lane-correcting brake application occurs,
display C appears in the multifunction dis-
play.
A lane-correcting brake application can only
be made after driving over a solid, recogniz-
able lane marking. Before this, a warning
must be given by means of intermittent vibra-
tion in the steering wheel. In addition, a lane
with lane markings on both sides must be
recognized. The brake application also
slightly reduces vehicle speed.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
