170 Driving and Driving Safety
Lane Change Assist (LCA)
Lane Change Assist (LCA) uses radar sensors to
help the driver to monitor the blind-spot area and
the traffic situation behind the vehicle.
Warning indicators are integrated in both door
mirrors. The warning indicator B on the left door
mirror assists the driver in changing into the left
lane, while the warning indicator on the right door
mirror assists the driver in changing into the right
lane.
The warning indicator lights up to indicate that
the Lane Change Assist system on this side has
detected a vehicle and considers this critical for
changing lanes. This form of display is called the
information stage. The information stage is
designed so that you notice it merely by glancing
at the door mirror.
When you set the turn signal and Lane Change
Assist has detected a vehicle that it regards as
critical, the warning indicator on the door mirror
will flash brightly several times. This form of
display is called the warning stage.

Information
The system helps when driving on highways and
on country roads. For this reason, it works at
a driving speed of between 20 and 156 mph
(30 and 250 km/h).
Even when using the Lane Change Assist, the
driver is still responsible for taking due care when
changing lanes and assessing the traffic situation.
f Please bear in mind that the sensors will not
detect all vehicles in every situation.
f Please note that Lane Change Assist cannot
alert you in good time to vehicles approaching
at high speed from behind or vehicles that are
falling back.
f Radar sensor vision can be impaired by rain,
snow or heavy spray. As a result, vehicles will
not be detected adequately or vehicles will not
be detected at all in some cases by Lane
Change Assist. Keep the direction of travel and
the relevant area around the vehicle in view at
all times.
f Please note that Lane Change Assist will only
alert you to approaching vehicles or vehicles in
the blind-spot area when you are driving at
20 mph (30 km/h) or faster.
f Please note that Lane Change Assist will not
work in tight corners (corner radius of less
than 109 yd. (100 m)).
f Even with Lane Change Assist, absolute care
and attention on the part of the driver is still
required while driving. Ultimately, the driver is
still responsible for changing lanes. Keep the
direction of travel and the relevant area around
the vehicle in view at all times.
Information
f To ensure that Lane Change Assist can work
properly:
Do not block the radar sensor area on the rear
bumper (see illustration) with objects
(e.g. stickers, bicycle carriers).
Also remove any snow and ice from this area.
f Do not cover the warning indicator on the door
mirror with stickers or other objects.
f Lane Change Assist switches on automatically
as soon as the electric connector is plugged
into the trailer socket.
f Lane Change Assist switches off automatically
if it detects that the radar sensors for Lane
Change Assist are covered.

172 Driving and Driving Safety
If the side windows in the driver’s or passenger’s
door are darkened with tinted film, the driver may
not be able to see the warning indicator on the
door mirror properly.
Detection area
The detection area of the radar sensors includes:
– the approach zone approx. 77 yd. (70 m) to
the rear and
– the blind-spot area.
The radar sensors cover the adjacent lane to the
left and right. Other lanes are not covered by the
radar sensors.
Information
Lane Change Assist does not measure the lane
width, but the system assumes that the lane has
a fixed width. The sensors cover this lane width at
the left and right.
When driving on narrow roads or when driving
off-center in a lane, it is possible that Lane Change
Assist will detect vehicles that are not in the very
next lane.
Operating principle
Lane Change Assist measures the distance and
speed difference of the detected vehicles
compared to your vehicle. Whenever Lane Change
Assist regards the speed difference and distance
as critical for changing lanes, this is indicated on
the relevant door mirror.
The warning indicator can light up when you are
overtaken by a vehicle or when you overtake
another vehicle.
When you overtake another vehicle slowly (speed
difference of less than 9 mph (15 km/h)), the
warning indicator lights up as soon as this vehicle
is in your blind-spot area and is detected by Lane
Change Assist. If there is a greater speed
difference, this is not indicated on the door mirror.
Information and Warning stage
Lane Change Assist has 2 warning indicator
stages:
– the information stage and
– the warning stage.
Depending on whether or not you have set the turn
signal to indicate that you intend to change lane,
Lane Change Assist helps you by activating the
relevant warning indicator stage.
Information stage
If you have not set the turn signal, Lane Change
Assist will inform you about detected vehicles that
will be regarded as critical for a possible lane
change. Whenever Lane Change Assist regards
the speed difference and distance of a detected
vehicle as critical, a weak light appears in the
warning indicator on the relevant door mirror.
The brightness of the information stage is
deliberately weak so as not to distract you while
driving without intending to change lanes and
looking at the road. The information stage is
clearly visible when you look in the door mirror.
Warning stage
When you set the turn signal and Lane Change
Assist has detected a vehicle on this side which it
regards as critical for changing lanes, the warning
indicator on the mirror on this side will start to
flash brightly. When the warning stage flashes
brightly several times, this should be an indication
for you to check the driving situation again by
looking in the door mirror and looking over your
shoulder.
Information
The brightness of the warning indicator on the
door mirror can be changed.
f Please see the chapter “SETTING DISPLAY
BRIGHTNESS ON DOOR MIRROR” on
page 175.
Driving and Driving Safety 173
Driving situation – vehicle approaching
fast
A – Warning indicator on door mirror does
not light up
The sensors do not detect a vehicle. No lights on
warning indicator on door mirror.
B – Warning indicator lights up in information
stage
The sensors detect a fast approaching vehicle –
on the left lane in the example. This vehicle is
already regarded as critical for changing lanes
due to the significant speed difference even
though it is still a good distance away.
The warning indicator on the door mirror lights
up in information stage.
C – Warning indicator flashes in warning
stage
When you set the turn signal in driving situation B,
the warning indicator on the door mirror will flash
brightly several times. Lane Change Assist is
telling you that you may have overlooked
a vehicle.
Information
– The faster a vehicle is approaching, the earlier
the warning indicator on the door mirror lights
up. You are alerted to all vehicles detected by
Lane Change Assist when they are in the
“blind-spot area” at the latest.
– Changing lanes can already be critical for
vehicles approaching at speed if there is still
no indication on the door mirror.
Driving situation – vehicle approaching
slowly
A – Warning indicator on door mirror does
not light up
The sensors detect a slowly approaching vehicle –
on the left lane in the example. Given the small
speed difference and the long distance, this is not
indicated on the door mirror.
B – Warning indicator lights up in information
stage
The slowly approaching vehicle is now closer.
The warning indicator on the door mirror lights up
in information stage.
Only when Lane Change Assist regards the speed
difference and distance as critical for changing
lanes will this be indicated on the door mirror.
You are alerted to all vehicles detected by Lane
Change Assist when they are in the “blind-spot
area” at the latest.
174 Driving and Driving Safety
C – Warning indicator flashes in warning
stage
When you set the turn signal in driving situation B,
the warning indicator on the door mirror will flash
brightly several times. Lane Change Assist is
telling you that you may have overlooked
a vehicle.
Information
– The faster a vehicle is approaching, the earlier
the warning indicator on the door mirror lights
up. You are alerted to all vehicles detected by
Lane Change Assist when they are in the
“blind-spot area” at the latest.
– Changing lanes can already be critical for
vehicles approaching at speed if there is still
no indication on the door mirror.
Driving situation – vehicles falling back
slowly
A – Warning indicator on door mirror does
not light up
Lane Change Assist has not yet detected the
vehicle you have overtaken. No lights on warning
indicator on door mirror.
B – Warning indicator lights up in information
stage
Lane Change Assist detects the vehicle that is
falling back slowly (speed difference of less than
9 mph (15 km/h)) on the right. The warning
indicator on the door mirror lights up in
information stage.
C – Warning indicator flashes in warning
stage
When you set the turn signal in driving situation B,
the warning indicator on the door mirror will flash
brightly several times. Lane Change Assist is
telling you that you may have overlooked
a vehicle.
Driving situation – vehicles falling back
fast
A – Warning indicator on door mirror does
not light up
Lane Change Assist has not yet detected the
vehicle you have overtaken. No lights on warning
indicator on door mirror.
B – Warning indicator on door mirror does
not light up
Lane Change Assist detects the vehicle that is
falling back fast (speed difference of more than
9 mph (15 km/h)) on the passenger’s side, but
does not regard it as critical for changing lanes
because it is falling back fast. No lights on warning
indicator on door mirror.
C – Warning indicator on door mirror does
not light up
When you set the turn signal in driving situation B,
there is still no indication on the door mirror.
Driving and Driving Safety 175
Setting display brightness on door mirror
The brightness of the warning indicator for both
the information stage and warning stage is
automatically adjusted according to the ambient
brightness.
You can also adjust the basic brightness as
required on the multi-purpose display.
f Please see the chapter “LANE CHANGE
ASSIST (LCA)” on page 131.
The new brightness is displayed briefly during the
setting process. This is the level of brightness
displayed for the information stage. The
brightness of the warning stage depends on the
brightness of the information stage.
f Set the brightness of the information stage so
that you can clearly see the warning indicator
lighting up when you look in the door mirror,
but cannot see it when you look straight ahead
through the windshield.
In very dark or bright surroundings, the warning
indicator may already be at the lowest or highest
level of automatic brightness adjustment. In such
cases, there may not be any noticeable change in
the brightness of the warning indicator on the door
mirror when you adjust the basic brightness.
When you change the basic brightness in very
bright or dark surroundings, you may not notice
any change until you are back in an area with
moderate ambient brightness.
Information
– Lane Change Assist is not active while you are
adjusting the brightness. The warning indicator
lights up briefly only to help you to set the
brightness.
– Your settings are automatically stored and
assigned to the radio key you are using.
General information
System-related limits are set for Lane Change
Assist while driving. Please drive with extreme
care therefore:
– when driving around corners
– when driving in lanes that are not of standard
width.
When driving around corners
– Lane Change Assist cannot detect vehicles in
tight corners (corner radius of less than
109 yd. (100 m)).
– When driving around a corner, Lane Change
Assist may react to a vehicle driving two lanes
over from you and the warning indicator on the
door mirror may light up.
Lane width
– The Lane Change Assist detection area is
designed in such a way that it covers the two
adjacent lanes (left and right) on lanes of
standard width regardless of whether you are
driving exactly in the middle or more on the
edge of your lane.
– When you are driving on narrow lanes, this area
may cover even more lanes, particularly if you
are driving at the edge of your lane.
In situations like this, vehicles driving two lanes
over from you can also be detected and Lane
Change Assist could switch to the information
or warning stage.
– Likewise, when driving on very wide lanes,
vehicles in the next lane may not be detected
because they are outside of the detection
area.
