Traffic Sign Assist is not available in all coun-
tries. In this case, display C appears in the
assistance graphic ( Y
page 221).
Important safety notes Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits. Traffic
signs always have priority over the Traffic Sign
Assist display.
The system may be either functionally impaired
or temporarily unavailable if the information in
the digital street map of the navigation system is
incorrect or out of date.
Activating Traffic Sign Assist X
Activate the Traffic Sign Assist display using
the on-board computer ( Y
page 222).
If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
appear in the instrument cluster for five seconds
in each case. The wrong-way warning and the
traffic sign display for speed limits and overtak-
ing restrictions remain active even when the
display has been deactivated.

trian recognition is active, pedestrians recog-
nized by the system are visually highlighted in
color in the Night View Assist Plus display with
small frame corners.
In addition, an infrared camera is integrated into
radiator trim C . The camera helps detect
pedestrians and animals. Observe the notes on
cleaning the infrared camera ( Y
page 324).
i Infrared light is not visible to the human eye
and therefore does not glare. Night View
Assist Plus can therefore remain switched on
even if there is oncoming traffic.
Important safety notes Night View Assist Plus is only an aid and is not a
substitute for attentive driving. Do not rely on
the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in good
time. Drive carefully and always adapt your driv-
ing style to suit the prevailing road and traffic
conditions.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to snow, rain,
fog or spray R
the windshield is dirty, fogged up or covered,
for instance by a sticker, in the vicinity of the
camera R
the infrared camera in the radiator trim is
dirty, fogged up or obscured R
on bends, hilltops or downhill gradients R
at high outside temperatures
Night View Assist Plus cannot display objects
directly in front of or beside the vehicle.
It is possible that, in addition to people and ani-
mals, other objects are also marked or highligh-
ted .
Pedestrian and animal recognition
General notes
Pedestrian or animal recognition may be
impaired or inoperative if: R
pedestrians or animals are partially or entirely
obscured by other objects, e.g. parked vehi-
cles R
the silhouette of the pedestrian or of the ani-
mal in the Night View Assist Plus display is incomplete or interrupted, e.g. by powerful
light reflections R
pedestrians or animals do not contrast with
the surroundings R
the camera system no longer recognizes
pedestrians as persons due to special cloth-
ing or other objects R
pedestrians are not in an upright position, e.g.
sitting, squatting or lying R
animals are not recognized by the system,
e.g. because of their size or shape
Pedestrian and animal recognition is deactiva-
ted at temperatures above 90 ‡ (32 †). The
spotlight function and automatic delayed
switch-off are then no longer active.

are no further warning tones.
Course-correcting brake application If Active Blind Spot Assist detects a risk of a lat-
eral 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 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,
the red warning lamp flashes in the exterior mir-
ror and a dual warning tone sounds. In addition,
a display underlining the danger of a side colli-
sion appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-cor-
recting brake application adapted to the driving
situation occurs if: R
there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehicle. R
a vehicle approaches you too closely at the
side. R
you have adopted a sporty driving style with
high cornering speeds. R
you clearly brake or accelerate. R
a driving safety system intervenes, e.g. ESP ®
or PRE-SAFE ®
Brake.R
ESP ®
is switched off.R
a loss of tire pressure or a defective tire is
detected. Switching on Active Blind Spot Assist X
Make sure that Active Blind Spot Assist is
activated in the on-board computer
( Y
page 223) X
Switch on the ignition.
Warning lamps in the exterior mirrors light up
red for approximately 1.5 seconds. Gray radar
waves propagating backwards appear next to
the vehicle in the assistance display on the
multifunction display.
Active Lane Keeping Assist General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera C at the top of the windshield. Various
different areas to the front, rear and side of your
vehicle are also monitored 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 unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
Important safety notes
If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of an
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take account of
road and weather conditions. It may not recog-
nize 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.206
Driving systems
Driving and parking

If a lane-correcting brake application occurs,
display C appears in the multifunction display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking recognize as
being solid or broken. Before this, a warning
must be given by means of intermittent vibration
in the steering wheel. In addition, a lane with
lane markings on both sides must be detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can
have an influence on brake application: oncom-
ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
A further lane-correcting brake application can
only occur after your vehicle has returned to the
original lane.
No lane-correcting brake application occurs if: R
you clearly and actively steer, brake or accel-
erate. R
you cut the corner on a sharp bend. R
you have switched on the turn signal. R
a driving safety system intervenes, e.g. ESP ®
,
PRE-SAFE ®
Brake or Active Blind Spot Assist.R
you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration. R
ESP ®
is switched off.R
the transmission is not in position D .R
a loss of tire pressure or a defective tire has
been detected and displayed. R
an obstacle in the lane in which you are driving
has been detected. Active Lane Keeping Assist may not detect other
road users or traffic situations. An inappropriate
brake application may be interrupted at any time
if you: R
steer slightly in the opposite direction. R
switch on the turn signal. R
clearly brake or accelerate.
A lane-correcting brake application is interrup-
ted automatically if: R
a driving safety system intervenes, e.g. ESP ®
,
PRE-SAFE ®
Brake or Active Blind Spot Assist. R
lane markings can no longer be recognized.
