Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R Cornering, going into and coming out of a
bend
R Vehicles traveling on a different line
R Other vehicles changing lanes
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
Cornering, going into and coming out of a bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late. 196
Driving systemsDriving and parking
Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the vehicle in front will be too short.
Other vehicles changing lanes DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road, because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally. Driving systems

DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot aids you in keeping the vehicle in the center of the driving lane by means of
moderate steering interventions in the speed
range from 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle by means of multifunction camera 0043, at the top
of the windshield.
At speeds of 0 - 37 mph (0 - 60 km/h),
Stop&Go Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h)
Steering Assist focuses on detected lane
markings (left and right), and only on the vehi- cle in front if lane markings are missing.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide
assistance.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of
an accident nor override the laws of physics.
It cannot take account of road, weather and
traffic conditions. DISTRONIC PLUS with
Steering Assist and Stop&Go Pilot 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 your
lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traf-
fic conditions. If you are following a vehicle
which is driving towards the edge of the road,
your vehicle could come into contact with the
curb or other road boundaries. Be particularly aware of other road users, e.g. cyclists, that
are directly next to your vehicle.
Obstacles such as building site huts on the
lane or projecting out into the lane are not
detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
The support provided by the system can be
impaired 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 no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
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
detected 198
Driving systemsDriving and parking
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
The system is switched to passive and no lon-
ger assists you by performing steering inter-
ventions if:
R you actively change lanes
R you switch on the turn signal
R take your hands off the steering wheel or do
not steer for a prolonged period of time
i After you have finished changing lanes,
Steering Assist and Stop&Go Pilot are auto-
matically active again.
DISTRONIC PLUS Steering Assist does not
provide assistance: R on very sharp corners
R when a loss of tire pressure or a defective
tire has been detected and displayed.
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 190).
The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if you take your hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you
have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the
vehicle. Steering Assist and Stop&Go Pilot are switched to passive. DISTRONIC PLUS
remains active. Activating Steering Assist and Stop&Go

General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h)
to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati- gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.
Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to recognize them at all. The system is not a
substitute for a well-rested and attentive
driver. The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R if the length of the journey is less than
approximately 30 minutes
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h)
R if you are driving with the DISTRONIC PLUS
Steering Assist activated
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
R you switch off the engine
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break
Displaying the attention level You can have current status information dis-
played in the assistance menu (Y

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 high-
way.
R the system recognizes solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend. Active Driving Assistance package
General notes The Active Driving Assistance package con-
sists of DISTRONIC PLUS (Y
page 189), Active
Blind Spot Assist (Y page 224) and Active
Lane Keeping Assist (Y page 227).
Active Blind Spot Assist General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehi-
cle, to monitor the area to the sides of the
vehicle which the driver is unable to see. 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
warning. If a risk of lateral collision is detec-
ted, corrective braking may help you avoid a
collision. Before a course-correcting brake
application, Active Blind Spot Assist evalu-
ates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses radar sensors which are
pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (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:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
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 observe the traffic conditions care-
fully, and maintain a safe lateral distance.
