Driving on flooded roads !
Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam-
age the engine, the electronics or the trans- mission.
If you must drive on stretches of road on
which water has collected, please bear in
mind that:
R in the case of standing water, the water
level may be no higher than the lower edge of the vehicle body
R you should drive no faster than walking
pace Winter driving

WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter.
You should drive particularly carefully on slip- pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres. Do
not use cruise control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges. The vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.

sideways, tip and overturn. There is a risk of
an accident.
When driving up an incline, drive into the line of fall (upwards or downwards in a straight
line) and do not turn. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could
be damaged without the damage being visi-
ble. Components damaged in this way can
unexpectedly fail or, in the case of an acci-
dent, no longer withstand the strain they
are designed for.
If the underbody panelling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody panelling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If, upon con-
tinuing your journey, you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to road and traffic conditions. In such cases,
consult a qualified specialist workshop.
The vehicle is only designed for easily nego-
tiable off-road terrain and poor road surfaces. When driving off-road, substances such as
sand, mud and water or water mixed with oil
may get into the brakes. This may lead to a
reduction in braking performance or total
brake failure as a result of increased wear.
The braking characteristics will vary depend-
ing on the substances that get into the
brakes. Clean the brakes after driving off-
road. If you notice grinding noises or a reduc-
tion in braking performance, have the brake
system checked at a qualified specialist work- shop immediately. Adapt your driving style to
the altered braking characteristics.
Driving off-road increases the possibility of
damage to the vehicle, which may cause
assemblies or systems to fail. Adapt your
driving style to the conditions of the terrain.
Drive carefully. Have vehicle damage rectified immediately at a qualified specialist work-
shop.
Do not shift into transmission position N
when driving off-road. You could lose control
of the vehicle if you attempt to brake the
vehicle using the service brake. If the gradient
is too steep for your vehicle, back up in
reverse gear.

Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.

WARNING
DISTRONIC PLUS brakes your vehicle with up to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD
function is activated, the vehicle brakes
automatically in certain situations.
To avoid damage to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of an accident nor override the laws of phys-
ics. DISTRONIC PLUS cannot take road and
weather conditions or traffic conditions into
account. DISTRONIC PLUS 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.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
R on smooth or slippery roads. Braking or
accelerating can cause the drive wheels to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can
be impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain R
interference by other radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
If DISTRONIC PLUS no longer detects a vehi-
cle in front, it may unexpectedly accelerate to the speed stored.
This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass
vehicles driving on the left (left-hand drive
countries)
R be so high in the left lane that you pass
vehicles driving on the right (right-hand
drive countries)
If there is a change of drivers, advise the new driver of the speed stored.

does not leave the lane.
The system may be impaired or may not func-
tion 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,

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

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

ger assists you by performing steering inter-
ventions if:
R you actively change lane
R you switch on the turn signal
R you 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. Steering Assist and Stop&Go Pilot cannot
provide assistance:
R on very sharp corners
R when towing a trailer
R a loss of tyre pressure or a defective tyre
has been detected and displayed
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 236).
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
switch to passive mode. DISTRONIC PLUS

and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND. Traffic Sign Assist
General notes Traffic Sign Assist displays the maximum
speed permitted and overtaking restrictions
to the driver in the instrument cluster. Driving onto a section of road in the wrong direction
triggers a warning. Traffic Sign Assist detects traffic signs with camera system :attached
behind the top of the windscreen. The data
and general traffic regulations stored in the
navigation system are also used to determine
the current speed limit.
If a traffic sign that is relevant to your vehicle is passed, the display of the speed limits and
overtaking restrictions is updated.
The display can also be updated without a
visible traffic sign if:
R the vehicle changes roads (e.g. motorway
exit or slip road)
R a village or town boundary is passed which
is stored in the digital map
R the last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction
(speed limit or overtaking restriction) is
passed, the sign is displayed for five seconds.
The currently applicable traffic regulation continues to be shown in the assistance
graphic display (Y
page 326).
The camera also detects traffic signs with a
restriction indicated by an additional sign
(e.g. in wet conditions).
The traffic signs are only displayed with the
restrictions if:
R the regulation must be observed with the
restriction, or
R Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either. Traffic Sign Assist is not available in all coun-
tries. In this case, display :is shown in the
speedometer.
Important safety notes Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits
and overtaking restrictions. Traffic signs
always have priority over the Traffic Sign
Assist display.
The system may be either functionally
impaired or temporarily unavailable if:
R visibility is poor, e.g. due to snow, rain, fog
or spray
R there is glare, e.g. from the sun being low in
the sky
R there is dirt, ice or misting on the wind-
screen in the vicinity of the camera 274

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunc-
tion camera :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
Keeping Assist can neither reduce the risk of
an accident 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 respon-
sible 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 vehi-
cle in its lane.
The system may be impaired or may not func-
tion 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 reflection from other vehicles
(e.g. if the road surface is wet)
R the windscreen is dirty, misted up, dam-
aged or covered, for instance by a sticker,
