Diesel (EN 590)
Fuel grade !
Whe nrefuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. You can other-
wise impair engin eoutput or damage the
engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with asulphur contentof
under 50 ppm .Otherwise, the emission
control syste mcould be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with ahigher sulphur conten tare available,
the vehicle's oil change interval sare
shorter. More information about intervals
for changing the oil can be obtained from
any Mercedes-Benz Service Centre.
! Only use fuel that complies with the EN
590 European standard .Fuel that does not
comply wit hEN590can lead to increased
wear, engin edamag eand damag etothe
exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver; see "Low out-
side temperatures".
! Use afilter when adding fuel from afuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can. For further information on "Fuel", see
(Y
page 334).
Low outside temperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can help to prevent operating problems. At
exceptionally low temperatures, it is possible
that the flow properties of the fuel may be
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistanc
eofdiesel fuel. The effective-
ness of aflow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factor sinensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefor ebeavoided. Follow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunction scan other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Servic eCentre. 162

sonous carbon monoxide (CO) may enter the
vehicle, resulting in loss of consciousness and
even death.
To assure sufficient fresh air ventilation, open
aw indow slightly on the side of the vehicle
not facing the wind.
At the onset of winter, have your vehicle win-
terproofed at aqualified specialist workshop,
e.g. at aMercedes-Benz Service Centre.
Observe the notes in the "Winter operation"
section (Y page 319).

Slippery road surfaces G
WARNING
Do not shift down for additional engine brak-
ing on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularlyc arefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission: shift
the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.

snow chains, see (Y page 320). Driving systems
Cruise control
Important safety notes Cruise control maintains
aconstant road
speed for you. It brakes automaticallyino rder
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing atrailer, you must
shift to alower gear in good time or select
shift range 1,2or 3on vehicles with auto-
matic transmission. 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. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. You can
store any road speed above 30 km/h. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at aconstant speed (e.g. heavy traffic Driving systems

Z

On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing atrailer,
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 as lower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain apreset distance to the
vehicle in front. G
WARNING
Do not change down for additional engine
braking on aslippery 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-
cle sd riving on adifferent line. Therefore,
always pa yattention to traffic conditions even
when DISTRONIC PLU Sisactivated. Other-
wise, yo umay fai ltorecognis edanger sin

and others. G
WARNING
DISTRONIC PLU Scanno ttake account of road
and traffic conditions .IfDISTRONIC doe snot
recognise or no longer recognises the vehicle
in front,don ot 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 alane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on amotor-
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-
tancec ontrol 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 345).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 229) and operational. 172

DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distanc
etothis vehicle
will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in fron
tonthe edge of the carriage-
way,b ecause of its narrow width. The dis-
tance 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
acorner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally.
SPEEDTRONIC
Important safety notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. On long and
steep downhill gradients, especiallyift
he
vehicle is laden or towing atrailer, you must
shift to alower gear in good time or select
shift range 1,2or 3on vehicles with auto-
matic transmission. 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 you need addi-
tional braking, depress the brake pedal
repeatedly rather than continuously. G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. 180

data" section to find out whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towin gatrailer,
the vehicle/trailer combination may not
exceed amaximum speed of 100 km/ hfor
reasons concerning the operatin gpermit.
This also applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towin gatrailer, your vehicle's handling
characteristic swill be differen tincomparison
to when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strongc rosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients, you
must shift to alower gear in good time, or on
vehicles with automatic transmission, select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Driving tips R
Maintain agreater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea level. When driving in mountainous areas,
notet hat the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. Folding out the ball coupling
Before you can tow atrailer with your vehicle,
you must fold out the ball coupling.
The release wheel is located behind the left-
hand side trim panel in the boot. G
WARNING
Make sure that the ball coupling is engaged,
either in its folded-out or folded-in position,
and that the indicator lamp is off.
Do not turn the release wheel when atrailer
is coupled up. Otherwise, the trailer might
detach. X

In the Heating submenu, you can select a
stored departure time or change adeparture
time. The auxiliary heating timer function calcu-
lates the switch-on time accordin
gtothe out-
side temperature so that the vehicle is pre-
heated by the departure time. When the
departure time is reached, the auxiliary heat-
ing continues to heat for afurther five
minutes and then switches off. The auxiliary
heating adopts the THERMATIC or
THERMOTRONIC temperature setting.
You can switch off the auxiliary heating by
using the remot econtrol or the auxiliary heat-
ing button on the centre console. G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. agarage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling station sorwhen your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
