The speed limit no longer applies
:.
i The unit for the speed limit (km/h or mph)
depends on the country in which you are driv-
ing. It is generally neither shown on the traffic
sign nor on the instrument cluster but must be
taken into account when observing the max-
imum permitted speed.
No entry (wrong-way warning) If no entry signs are passed, a warning message
is displayed in the instrument cluster should
Traffic Sign Assist detect that you are driving in the wrong direction. You will then also hear a
warning tone. You should immediately check
your direction of travel in order to avoid danger
to yourself and other road users.
i This function is not available in all countries. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 151) and Lane Keeping
Assist (Y page 153).
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 cor-
responding turn signal to change lanes, you will also receive a visual and audible collision warn-
ing. 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 no 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 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 specialist workshop.
Blind Spot Assist may no longer work properly.
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 barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. Driving systems
151Driving and parking Z
Example: Saloon
Blind Spot Assist monitors the area up to 3.0 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 driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the edge of their lane nearest your vehicle.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders
R warnings may be interrupted when driving
alongside long vehicles, for example lorries,
for a prolonged time
Warning display :
Warning display Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If Blind Spot Assist is activated, indicator
lamp :in the exterior mirrors lights up yellow
up to a speed of 30 km/h. At speeds above
30 km/h, the indicator lamp goes out and Blind
Spot Assist is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the correspond-
ing side lights up red. This warning always
occurs 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
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 monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. 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.
Activating Blind Spot Assist X Make sure that Blind Spot Assist is activated
in the on-board computer (Y page 165).
X Select key position 2with the Start/Stop but-
ton.
Warning lamps :in the exterior mirrors light
up red for approximately 1.5 second s and
then turn yellow. 152

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. If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent 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 if:
R there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,fog or spray
R there is 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
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered 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 detec-
ted
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 highly variable shade conditions on
the road

WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
