the accelerator pedal.
Active Parking Assist no longer supports you
with steering interventions and brake appli-
cations. When Active Parking Assist is fin-
ished, you must steer and brake again your-
self. PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion 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 can-
cel the parking procedure with Active Park-
ing Assist.
RYou can also select preselect transmission
position D. The vehicle redirects and does
not drive as far into the parking space.
Should the transmission change take place
too early, the parking procedure will be
canceled. A sensible parking position can
no longer be ach ieve
d from this position.
Exiting a parking space
In order that Active Parking Assist can sup-
port you when you exit 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

Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
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.
iIf PARKTRONIC detects obstacles, Active

222Driving systems
Driving an d parking

If you select the reverse gear, Active Blind
Spot Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the
surroundings.
When Active Blind Spot Assist is activated,
gray radar waves propagating backwards
appear next to the vehicle in the assistance
display in the multifunction display. Above a
speed of 20 mph (30 km/h), the color of the
radar waves in the assistance display
changes to green;. Active Blind Spot Assist
is then ready for use.
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 will then hear
a double warning tone and red warning
lamp :flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp :. There are no fur-
ther 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.
GWARNING
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 Blind 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 :flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display ;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).
Either no braking application, or a course-
correcting brake application adapted to the
driving situation occurs if:
Rthere are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehi-
cle.
Ra vehicle approaches you too closely at the
side.
Ryou have adopted a sporty driving style with
high cornering speeds.
Ryou clearly brake or accelerate.
Ra driving safety system intervenes, e.g.
ESP®or PRE-SAFE®Brake.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of multi-
function camera :at the top of the wind-
shield. Various different areas to the front,
rear and side of your vehicle are also moni-
tored with the aid of the radar sensor system.
Active Lane Keeping Assist detects lane
markings on the road and can warn you
before you leave your lane unintentionally. If
you do not react to the warning, a lane-cor-
recting application of the brakes can bring the
vehicle back into the original lane.
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor override the laws of phys- ics. Active Lane Keeping Assist cannot take
account of road and weather conditions. It
may not recognize traffic situations. Active
Lane Keeping Assist is only 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.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
to the vehicle
Rnot give a warning or intervene
There isa risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention ina non-critical driv-
ing situation.
The system may be impaired or may not func-
tion if:
Rthere is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
Rthere is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged or covered, for instance by a sticker, in the
vicinity of the camera
Rthe radar sensors in the front or rear bump-
ers or the radiator trim are dirty, e.g.
obscured by snow
Rthere are no, several or unclear lane mark- ings for a lane, e.g. in areas with road con-
struction work
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow

Rthere are strong shadows cast on the road
If no vehicle is detected in the adjacent lane
and broken lane markings are detected, no
lane-correcting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you by
means of intermittent vibration in the steer-
ing wheel for up to 1.5 second s.
Lane -correcting brake application
If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane.
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
If a lane-correcting brake application occurs,
display :appears in the multifunction dis-
play. The brake application also slightly
reduces vehicle speed. This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can be
made after driving over a lane marking detec-
ted as being solid or broken. Before this, a
warning must be given by means of intermit-
tent vibration in the steering wheel. In addi-
tion, a lane with lane markings on both sides
must be recognized.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detec-
ted in the adjacent lane. Oncoming vehicles,
overtaking vehicles and vehicles in adjacent
lanes can be detected.
iA further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
Ryou clearly and actively steer, brake or
accelerate.
Ryou cut the corner on a sharp bend.
Ryou have switched on the turn signal.
Ra driving safety system intervenes, e.g.
