G
Risk of accident
Distronic Plus cannot take account of road
and traffic conditions. If Distronic does not
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 in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at motorway/road-
way construction sites
Otherwise, Distronic Plus maintains the cur-
rent speed 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. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 362).
If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic
Plus works like cruise control in the speed
range between 30 km/h and 200 km/h. If a
vehicle is driving in front of you, Distronic Plus
works in the speed range between 0 km/h
and 200 km/h. Do not use Distronic Plus while driving on
roads with steep gradients. G
Risk of accident
Distronic Plus brakes your vehicle at a maxi-
mum of 4m/s2
depending on its speed. This
corresponds to approximately 40% of your
vehicle's maximum brake force. You must
also apply the brakes yourself if this braking
power is not sufficient.
If Distronic Plus detects a risk of collision with
a vehicle in front, an intermittent warning tone
sounds. In addition, the ·distance warn-
ing lamp in the instrument cluster lights up.
Brake to avoid a collision.

Distronic Plus and variable Speedtronic.

R
the boot lid/tail gate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light (the dis-
play may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
event have the camera position and setting
checked at a qualified specialist workshop.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose.
Do not use the reversing camera in these
types of situation. You could, otherwise,
injure others or damage objects and your
vehicle while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Make sure that the "Reversing camera"
function is selected in COMAND APS (see
the separate operating instructions for
COMAND APS).
X Engage reverse gear.
The area behind the vehicle is shown in the
COMAND APS display.
You can select not to show the area behind
the vehicle in the COMAND APS display (see
the separate operating instructions for
COMAND APS). ATTENTION ASSIST
ATTENTION ASSIST helps you on long, monot-
onous journeys such as on motorways and
trunk roads. It is active at speeds between 80
and 180 km/h. If ATTENTION ASSIST detects tiredness or increasing lapses in concentra-
tion on the part of the driver, it suggests a
break. G
Risk of accident
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not a substitute
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 accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or increasing inattentiveness taking
into consideration the following criteria:
R personal driving style, e.g. steering charac-
teristics
R driving conditions, e. g. time, driving time
ATTENTION ASSIST's functionality is restric-
ted and warnings are delayed or do not
appear at all:
R if the road condition is poor, e.g. large
bumps or potholes
R there is a strong side wind
R you have adopted a very sporty driving style
with high cornering speeds or driving with
a high rate of acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently operating or making a
call using COMAND APS*
R in active driving situations, for example, if
you are changing lanes or changing the
vehicle speed Driving systems

could otherwise endanger yourself and oth-
ers.
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 the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R on bends, on uphill gradients or downhill
gradients.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist Plus
display in the multi-function display. This is
also the case if you cannot switch on the
main-beam headlamps because of oncoming
traffic. G
Risk of accident
Night View Assist Plus does not detect
objects in the immediate vicinity of the vehi-
cle. Look through the windscreen when
manoeuvring. Make sure that there are no
people or animals in the area in which you are
manoeuvring.
i Infrared light cannot be seen by the
human eye and therefore does not dazzle.
Night View Assist Plus can therefore
remain switched on even if there is oncom-
ing traffic. :

Because of this, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear.
Tyre grip
G
Risk of accident
While the vehicle can be fully controlled at a
certain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. Otherwise, you could cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), a thin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre grip. Drive with particular care in such
weather conditions. Driving on wet roads
If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully. Driving on flooded roads
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permitted still water depth is
25 cm.
R you should drive no faster than at walking
pace.
! 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.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 216). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. This prevents
oncoming traffic from being dazzled.
Have the headlamps converted as close as
possible to the border before driving in these
countries. When using symmetrical lights, the
edge of the carriageway is not illuminated as
widely and as far ahead as normal. Driving abroad
