When Blind Spot Assist is activated, grey radar
waves propagating backwards appear next to
the vehicle in the Assist image on the multifunc-
tion display (Y page 231). Above a speed of
30 km/h, the colour of the radar waves in the
Assist image changes to green :. Blind Spot
Assist is then ready for use.

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
vicinity of the camera 206

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-

R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes

R you accelerate hard, e.g. kickdown
R you brake hard
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly
R you cut the corner on a sharp bend
To ensure that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system detects certain conditions
and warns you accordingly.
The warning vibration occurs earlier in the fol-
lowing situations:
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 in the follow- ing situations:
R the road has narrow lanes
R you cut the corner on a bend Driving Assistance Plus package
General notes The Driving Assistance PLUS package consists
of DISTRONIC PLUS (Y page 171), Active Blind
Spot Assist (Y page 207)and Active Lane Keep-
ing Assist (Y page 210).
Active Blind Spot Assist General notes
Using two lateral, rear-facing radar sensors,
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not visible to
the driver. A warning lamp lights up on the exte- Driving systems
207Driving and parking Z

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 you are
driving alongside particularly long vehicles,
such as lorries, for a prolonged time
Warning lamp :
Warning lamp
Active Blind Spot Assist is not operational at
speeds of below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If a vehicle is detected within the blind spot
monitoring range at speeds of more than
approximately 30 km/h, warning lamp :on
the corresponding side lights up red. This warn-
ing lamp always lights up when a vehicle enters the blind spot 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 the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings. When Active Blind Spot Assist is activated, grey
radar waves propagating rearwards appear next
to the vehicle on the assistant display on the
multifunction display. Above a speed of
30 km/h, the colour of the radar waves on the
assistant display changes to green ;. Active
Blind Spot Assist is then ready for use.
Visual and audible 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 audible 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-
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
209Driving and parking Z

Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur in the following situations:
R vehicles or obstacles, e.g. crash barriers, are
located 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 brake or accelerate significantly
R a driving safety system engages, 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 on the on-board computer
(Y page 233).
X Switch on the ignition.

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
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting brake application can bring the
vehicle back into the original lane.
This function is available in a speed range
between 60 km/h and 200 km/h.
Important safety notes Active 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.
Active Lane Keeping Assist cannot take account of road and weather conditions. It may not rec-
ognise certain road and traffic conditions.
Active Lane Keeping Assist is only an aid. You
are responsible for the distance to the vehicle in

Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane. G
