= Additional sign for unknown restriction
A maximum permissible speed of 80 km/h
(80 mph) and a speed limit of 60 km/h (60 mph) with an unknown restriction apply.
The unit for the speed limit (km/h or mph)
depends on the country in which you are driving.
It is generally neither shown on the traffic sign
nor on the instrument cluster but must be taken
into account on observance of the maximum
permissible speed.
No entry (wrong-way warning) A warning message
:is displayed on the
instrument cluster if Traffic Sign Assist detects
that you are passing a “no entry” sign and you
are driving in the wrong direction. You will then
also hear a warning tone. You should immedi-
ately check your direction of travel in order to
avoid danger to yourself and other road users. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 204) and Lane Keeping
Assist (Y page 206).
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 lamp lights up on the exterior
mirror and 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 warning.
Blind Spot Assist supports you from a speed of
approximately 30 km/h.
Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is not a substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
Radar sensors The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free of dirt, ice and slush. The sen- sors must not be covered, e.g. by cycle racks oroverhanging loads. Following a severe impact or in the event of damage to the bumpers, have the
function of the radar sensors checked at a quali- 204
Driving systemsDriving and parking

fied specialist workshop. Blind Spot Assist may
no longer work properly in such cases.
Monitoring range In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. At a distance of around 0.5 m
;from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 mnext to =and behind :your vehicle, as
shown in the picture.
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 the vehicles are driving on the inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time Warning lamp
:
Warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp :on the cor-
responding side lights up red. This warning lamp always lights up when a vehicle enters the blindspot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select reverse gear, Blind Spot Assist is
not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the blind spot moni-
toring range and you switch on the correspond-
ing turn signal, a double warning tone sounds.
The red warning lamp flashes on the relevant
exterior mirror. If the turn signal remains on,
detected vehicles are indicated by the flashing
of the red warning lamp on the exterior mirror.
There are no further warning tones.
Activating Blind Spot Assist

Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :attached at the top of the windscreen.
Lane Keeping Assist detects lane markings on
the road and can warn you before you leave your lane unintentionally. This function is available in a speed range
between 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 through the steering
wheel for up to 1.5 seconds.
Important safety notes G
WARNING
Lane Keeping Assist cannot always clearly
identify lane markings.
In these cases, 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 keep in lane, especially if Lane
Keeping Assist alerts you. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
Lane Keeping Assist can neither reduce the risk
of an accident if you fail to adapt your driving
style nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. 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
lane.
Lane Keeping Assist does not keep your vehicle in its lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the

tone and red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid 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, red warning lamp :flashes on the exterior mir-
ror and a double warning tone sounds. In addi-
tion, a display underlining the danger of a side
collision appears on 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 30 km/h and
200 km/h. Driving systems

Warning vibration through the steering
wheel 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 steering wheel for
up to 1.5 seconds. Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces, the vehicle will brake briefly on one side.
This is intended to help you return the vehicle to the original lane. G
WARNING
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 on the multifunction display.
The brake application also slightly reduces driv- ing speed.
A lane-correcting brake application can be made
after the car has passed over a lane marking
detected as being solid or broken. Before this, a warning must have been issued by means of
intermittent vibration through 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 be made only 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
occur only after your vehicle has returned to the original lane.
