Important safety notes
GWARNING
Lane Keepin g Assist cannot always clearly
detect lane markings.
In such cases, Lane Keepin g Assist can:
Rgive an unnecessary warning
Rnot give a warning
There isa risk of an acc ident.
Always pay particular attention to the traff ic
situation and keep within the lane, especial ly
if Lane Keepin g Assist alerts you.
GWARNING
The Lane Keepin g Assist warning does not
return the veh icleto the original lane. There is
a risk of an acc ident.
You should always steer, brake or accelerate
yourself, inparticular ifwarned byLane Keep-
ing Assist.
Lane Keepin g Assist can neither reduce the risk
of an acc identif you fail to adapt your driving
style nor overr idethe laws of physics. Lane
Keepin g Assist cannot take into account the
road, traff icand weather conditions. Lane Keep-
ing Assist ismerely an aid.You are responsible
for the distance to the veh icle infront, for veh i-
cle speed, for braking ingood time and for stay-
ing inyour lane.
The Lane Keepin g Assist does not keep the veh i-
cle inthe lane.
The system may beimpaired or may not function
if:
Rthere ispoor vis ibility, e.g. due to insuff icient
illumi nation of the road, or due to snow, rain,
fog or spray
Rthere isglare, e.g. from oncoming traffic, the
sun or reflection from other veh icles (e.g. if
the road surface iswet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance bya sticker, inthe vicin-
ity of the camera
Rthere are no, several or unclear lane markings
for a lane, e.g. inareas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirtor snow
Rthe distance to the vehicle infront 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 isnarrow and winding
Rthere are highly variable shade conditions on
the roadway

Active Blind Spot Assis tsupport syou from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist isonly an aid and is not
a substitute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may ne i-
ther give warnings nor intervene insuch sit-
uations. There isa risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.

Radar sensors
The Active Blind Spot Assist radar sensors are
integrated into the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
grill are free of dirt, ice or slush. The rear sensors
must not be covered, for example by cycle racks
or overhanging cargo. Following a severe impact
or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Active Blind Spot
Assist may otherwise no longer work properly.
Monitoring area
GWARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance on the side for other traffic or obstacles.
At a distance of approximately 1.6 ft (0.5 m);
from the vehicle, Active Blind Spot Assist mon-
itors the area up to 10 ft (3 m) next to =and
behind :your vehicle, as shown in the picture. The detection of obstacles can be impaired in
the case of:
Rthere is dirt on the sensors or anything else
covering the sensors
Rpoor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the inner edge of
your lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarnings may be interrupted when you are
driving alongside particularly long vehicles,
such as trucks, for a prolonged time.
Warning lamp
:Warning lamp
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).

Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces 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 display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking detected 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 recog-
nized.
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. Oncoming vehicles, over-
taking vehicles and vehicles in adjacent lanes
can be detected.
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:
Ryou clearly and actively steer, brake or accel-
erate.
Ryou cut the corner on a sharp bend.
Ryou have switched on the turn signal.
Ra driving safety system intervenes, e.g. ESP®,
PRE-SAFE®Brake or Active Blind Spot Assist.
Ryou have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration.
RESP®is switched off.
Rthe transmission is not in position h.
Ra loss of tire pressure or a defective tire has
been detected and displayed.
Ran obstacle has been detected in the lane in
which you are driving.
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:
Rsteer slightly in the opposite direction.
Rswitch on the turn signal.
Ryou brake or accelerate significantly.
A lane-correcting brake application is interrup-
ted automatically if:
Ra driving safety system intervenes, e.g. ESP®,
PRE-SAFE®Brake or Active Blind Spot Assist.
Rlane markings are no longer detected.
