Lane Keeping Assist
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognizelane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot giveawarning
There isarisk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
isarisk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane
Keeping 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
function 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 oncomingtraffic,
the sun or reflections (e.g. when the road
surface is wet)
Rthe windshield is dirty, fogged up, damaged
or covered, for instancebyasticker, in the
vicinity of the camera
Rthere are no, several or unclear lane
markings foralane, e.g. in areas with road
construction work
Rthe lane markings are worn away,dark or
covered up, e.g. by dirt or snow

Active Blind Spot Assist
Generalnotes
Active Blind Spot Assistusesaradar sensor
system, pointed toward the rear of the
vehicle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning displayinthe exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. Ifarisk of lateral collision is
detected, corrective braking may help you
avoidacollision. Beforeacourse-correcting
brake application, Active Blind Spot Assist
evaluates the space in the direction of travel
and at the sides of the vehicle. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:
Ractivated(Ypage 232)
Roperational
Important safety notes
Active Blind Spot Assist is only an aid and is
notasubstitute 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 withalarge speed
differential and overtakeyour vehicle
Asaresult, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There isarisk of an accident.
Always observe the traffic conditions
carefully, and maintainasafe lateral distance.

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
distance on the side for other traffic or
obstacles.
Active Blind Spot Assist monitors the area up
to 10 ft (3.0 m) behind your vehicle and
directly next to your vehicle, as shown in the
diagram.
The detection of obstacles can be impaired in
the case of:
Rdirt 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 or indicated withadelay.
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
driving in the middle of their lane. This may
be the case if there are vehicles at the edge
of their 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.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
Indicator and warning display
Yellowindicator 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 lampin 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.
Ifavehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
20 mph (30 km/h), warning lampon the
corresponding side lights up red. This warning
is always given whenavehicle enters the
blind spot monitoring range from behind or
from the side. When you overtakeavehicle,
the warning only occurs if the difference in
speed is less than7mph (12km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event,Active Blind
Spot Assist is no longer active.

The brightness of the indicator/warning
lamps is adjusted automatically accordingto
the ambient light.
Visual and acoustic collision warning
If you switch on the turn signals to change
lanes andavehicle is detected in the side
monitoring range, you receiveavisual and
acoustic collision warning. You then hear a
double warning toneand red warning
lampflashes. If the turn signal remains on,
detected vehicles are indicated by the
flashing of red warning lamp.There are no
further warning tones.
Course-correcting brake application
GWARNING
Acourse-correctingbrake application cannot
alwayspreventacollision. There isarisk of
an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makesacourse-correcting brake
application. Always maintainasafe distance
at the sides.
If Active Blind Spot Assist detectsarisk 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.
Ifacourse-correcting brake application
occurs, red warning lampflashes in the
exterior mirror andadual warning tone
sounds. In addition, the display shown in the
lower image appears in the multifunction
display.
In very rare cases, the system may make an
inappropriate brake application. An
inappropriate course-correcting brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate, for example.
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, oracourse-
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
vehicle.
Ravehicle approaches you too closely at the
side.
Ryou have adoptedasporty driving style with
high cornering speeds.
Ryou clearly brake or accelerate.
