which the restriction in the additional sign is
relevant
= Additional sign for unknown restriction
A maximum permitted speed of 80 km/h
(80 mph) and a speed limit of 60 km/h (60 mph) with an unknown restriction apply.
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. Active Driving Assistance package
General notes The Active Driving Assistance package consists
of Distance Pilot DISTRONIC (Y page 161),
Steering Pilot and Stop&Go Pilot, Active Blind
Spot Assist (Y page 193) and Active Lane Keep-
ing Assist (Y page 195). Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not directly
visible to the driver with two lateral, rear-facing radar sensors. A warning light in the exterior
mirrors draws your attention to vehicles detec-
ted in the monitored area. If you then switch on
the corresponding turn signal to change lanes,
you will also receive a visual and audible colli-
sion warning. If a risk of side impact is detected,
corrective braking may help you avoid a colli-
sion. Active Blind Spot Assist evaluates the free space in the direction of travel and to the side
before making a course-correcting brake appli-
cation. For this, Active Blind Spot Assist uses
the forward-facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. 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.
Radar sensors
The radar sensors for Active Blind Spot Assist
are integrated in the rear bumper and in the
radiator trim. Make sure that the bumpers and
radiator trim are free from dirt, ice and slush.
The rear sensors must not be covered, e.g. by
bicycle 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.
Active Blind Spot Assist may otherwise no lon-
ger function properly. Driving systems

Monitoring range
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 to the side for other traffic or obstacles. Active 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.
The detection of vehicles may be impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
indicated.
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 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 particularly long vehicles, for exam-
ple lorries, for a prolonged time
Indicator and warning display :
Yellow indicator lamp/red warning lamp
Active Blind Spot Assist is not active at speeds
below approximately 30 km/h. Vehicles in the
monitoring range are then not indicated.
If Active 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 Active Blind Spot Assist is operational.
If a vehicle is detected within the monitoring
range at speeds above 30 km/h, warning
lamp :on the corresponding side lights up red.
This warning always occurs when a vehicle
enters the monitoring range from behind or from
the side. When you overtake a vehicle, the warn-
ing only occurs if the difference in speed is less
than 12 km/h.
The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is then no longer active.
The brightness of the indicator/warning lamps
is adjusted automatically according to the ambi-
ent light.
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 will then hear a double warning
tone and red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica- 194

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 in the exterior mir-
ror and a dual warning tone sounds. In addition, display ;underlining the danger of a side col-
lision appears in 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 if you steer slightly in the opposite
direction or depress the accelerator pedal more
firmly.
The course-correcting brake application is avail-
able within a speed range between 30 km/h and 200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle
R a vehicle approaches too closely on the side R
you have adopted a sporty driving style with
high cornering speeds
R you clearly brake or accelerate
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake
R ESP ®
is deactivated
R a loss of tyre pressure or a defective tyre is
detected
Activating Active Blind Spot Assist X
Make sure that Active Blind Spot Assist is
activated (Y page 208).
X Turn the key to position 2in the ignition lock.
Warning lamps :in the exterior mirrors light
up red for approximately 1.5 second s and
then turn yellow.
Active Lane Keeping Assist General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera :at the top of the windscreen. Various
different areas to the front, rear and side of your vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and Driving systems
195Driving and parking Z
Page 199 of 333
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available within a speed range
between 60 km/h and 200 km/h.
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must be
operational.
Important safety notes
If you fail to adapt your driving style, Active Lane Keeping Assist can neither reduce the risk of an
accident nor override the laws of physics. Active Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Active Lane
Keeping Assist is only an aid. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in lane.
Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane. G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
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
there are no lane markings or several unclear
lane markings, e.g. around construction sites
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 roadway
R no vehicle is detected in the adjacent lane and
there are broken lane markings
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.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system detects certain conditions and
warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend
R the road has very wide lanes, e.g. a motorway
R the system detects solid lane markings
The warning vibration occurs later if:
R the road has narrow lanes
R you cut the corner on a bend
Lane-correcting brake application 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. G
WARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate 196

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.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop.
For an overview, see the instrument cluster illus-
tration (Y page 32). Displays and operation
Instrument cluster lighting

R Distance Pilot DISTRONIC detects a vehicle in
front moving more slowly than the stored
speed:
The segments between the speed of the vehi-
cle in front and the stored speed light up. Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
