Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist ( Y
page 244) and Lane Keeping
Assist ( Y
page 246).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in
the monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive a visual and audible col-
lision warning.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/ h) . Important safety notes
G WARNING
Blin d Spot Assist does not react to: R
vehicles overtaken too closely on the side,
placing them in the blind spot area R
vehicles which appr oach with a large speed
differential and overtake your vehicle
As a result, Blin d Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Radar sensors
The radar sensors for Blind Spot Assist are
integrated into the rear bumper. Make sure
that the bumpers are free from dirt, ice or
slush. The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the radar sensors checked at a qualified spe-
cialist workshop. Blind Spot Assist may no
longer work properly.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is poor visibility, e.g. due to fog, heavy
rain or snow R
narrow vehicles, e.g. motorcycles or bicy-
cles R
the road has very wide lanes R
the road has narrow lanes R
you are not driving in the middle of the lane R
there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated. Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram.
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 driving at the
inner edge of their lanes.
Due to the nature of the system: R
warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders. R
the warning is canceled when driving for an
extended period next to long vehicles, such
as trucks.
Warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated. Driving systems 245

C
Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator
lamp C in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At
speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the corre-
sponding 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).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds. Red warning lamp C flashes. If
the turn signal remains on, detected vehicles
are indicated by the flashing of red warning
lamp C . There are no further warning tones.

tion lock.
Warning lamps C in the exterior mirrors
light up red for approximately 1.5 seconds
and then turn yellow.
Towing a trailer
When you attach a trailer, make sure you have
cor rectly established the electrical connec-
t ion . This can be accomplished by checking
the trailer lighting. In this event, Blind Spot
Assist is deactivated. The indicator lamp in
the exterior mirrors lights up yellow, and the
Blind Spot Assist Currently Unavail‐
able See Operator's Manual message
appears in the multifunction display.
i You can deactivate the indicator lamps in
the exterior mirrors.

the road and can warn you before you leave
your lane unintentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
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.
Im portant safety notes
G WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may: R
give an unnecessary warning R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
G WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing 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 func-
tion if: R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray R
there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet) R
the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow R
the distance to the vehicle in front is too
small and the lane markings thus cannot be
d e tected R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge R
the road is narrow and winding R
there are strong shadows cast on the road
Switching on Lane Keeping Assist X
Switch on Active Lane Keeping Assist using
the on-board computer; to do so, select

In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
dit ions and warns you accordingly.
The warning vibr ation occurs earlier if:R
you appr oach the outer lane marking on a
ben d. R
the road has very wide lanes, e.g. a high-
way. R

Active Blind Spot Assist
General notes
Active Blin d Spo t Assist mon it ors the areas
on either side of the vehicle that are not
dire ct ly vis ible to the driver with two lateral,
rear-facing radar sensors. A warning lamp
lights up in the exterior mirrors and draws your attention to vehicles detected in the
mon it ored area. If you then switch on the cor-
respon din g turn signal to change lanes, you
will also receive a visual and audible co llisio n
warning. If a risk of lateral co llisio n is detec-
te d, correct ive braking may help you avoid a
co llisio n. Before a course-correcting brake
applic ation, Acti ve Blind Spo t Assist evalu-
ates the space in the dire ction of travel and at
the sides of the vehicle. For this, Acti ve Blind
Spot Assist uses the forward-facing radar
sensors.
Acti ve Blind Spo t Assist supports you from a
speed of approximately 20 mph (30 km/h).

Monitoring area
G WARNING
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. Active Blind Spot Assist monitors the area up
to 10 ft (3.0 m) behi nd your vehicle and
directly next to your vehicle, as shown in the
diagram.
In particular, the detection of obstacles can
be impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
poor visibility, e.g. due to rain, snow or
spray
Vehicles in the monitoring range are then not
reliably indicated.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicy-
cles, 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: R
warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders. R
warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time. Driving systems 249

Indicator and warning display
C
Yellow indicator 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 lamp C in 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.
If a vehicle is detected within the monitoring
range at speeds above approximately 20 mph
(30 km/h), warning lamp C on the corre-
sponding side lights up red. This warning lamp
always lights up when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle
with a difference in speed of less than 7 mph
(12 km/h), a delayed warning occurs.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is
not operational.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the brightness of the surroundings.
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 then hear a
double warning tone and red warning lamp C
flas hes. If the turn signal remains on, detec-
ted vehicles are indicated by the flashing of red warning lamp C . There are no further
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.
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 Blin d 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 C flashes in the
exterior mirror and a dual warning tone
sounds. In addition, display D 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).250
