On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effect of the engine, which relieves
the load on the brake system and prevents
the brakes from overheating and wearing too
quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain a preset distance to the
vehicle in front. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front,e .g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC doe snot
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on a motor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. You will find further
information under "Radar sensor system"
in the index.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 363).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 226) and operational. Driving systems
165Driving and parking Z

If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed,
but only up to the desire
dspeed you have
stored. G
WARNING
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longer brakes your
vehicle. In such cases, control the distance
from vehicles travelling in fron twith the brake
alone. You could otherwise cause an accident
and thereby injure yourself and others. The
drive rremains fully responsible for the vehi-
cle's distance from other vehicles, the speed
being driven and for braking in good time.
Changing lanes
If you wish to change to the passing lane (in
countries where traffic drives on the right, the
passing lane is the left-hand lane), DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front.
R you switch on the appropriate turn signals.
R DISTRONIC PLUS does not detec tadanger
of collision.
If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
fron tbecomes too small. G
WARNING
DISTRONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
They do not relieve you of the responsibility
of paying attention .The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. Vehicles with COMAND Online
i
The following function is not operational
in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic situa-
tions. This is the case if, while following a
vehicle, DISTRONIC PLUS is active and you:
R approach or drive through aroundabout
R approach a T junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detec-
tion range, DISTRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is based on the current
map data in the navigation system. Example: roundabout
The current speed is maintained:
R
approximately 10 seconds before the
roundabout/T junction and for approx-
imately 1.5 seconds when driving on the
roundabout
R approximately 12 seconds before reaching
a motorway exit and approximately 4sec-
onds after the motorway exit
Afterwards, the vehicle accelerates back to
the set speed you specified.
Stopping G
WARNING
Never get out of the vehicle when DISTRONIC
PLUS is activated. 168

Important safety notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break. G
WARNING
ATTENTION ASSIST is only an aid and may
detect yourt iredness or lapses in concentra-
tion too late or not at all. It is not asubstitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an acciden tand
injure yoursel fand others.
ATTENTIO NASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R driving conditions, e.g. time, driving time The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
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 sid ewind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND Online
or making a telephone call with it
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed

Driving systemsDriving and parking

still detects typical indicators of fatigue or
increasing lapses in concentration, you will be
warned againa fter 15 minutes at the earliest.
ATTENTION ASSIST is reset when you con-
tinue you rjourney and it 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. Speed Limit Assist
Important safety notes i
Speed Limit Assist is not operational in all
countries.
Speed Limit Assist shows you detected speed
limits in the multifunction display .Data from
the navigation system is also used for this
purpose. The display appears if a traffic sign
indicating a speed limit or the end of a speed
limit is detected. If Speed Limit Assist does
no td etec tany traffic signs, the speed limit
from the digital road ma pis taken and shown
in the display.
Speed Limit Assist detects the traffic signs
with a camera at the top of the windscreen. :
Speed Limit Assist camera G
WARNING
Speed Limit Assist is only an aid and may
detect speed limit signs incorrectly or not at
all. The system may be impaired or may not func-
tion if:
R
there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R the traffic signs are covered, for instance
by dirt, snow or trees.
R the traffic signs are poorly illuminated.
R there are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads.
Traffic signs always have priority over the
Speed Limit Assist display. Speed Limit Assist
cannot detect road and traffic conditions. It is
not a substitute for attentive driving.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourselfa nd others.
