THERMOTRON ICautomatic climat econtrol
controls the tempera tureand the humidit yof
the vehicle interior and filters out undesirable
subs tances fro mthe air.
THERMATIC/T HERMOTRONIC automatic cli-
mate control is only operational when the

Optimum operatio nisonly

and sliding sunroof/panoram asliding sun-
roof closed.
i Ventilate the vehicle for abriefp eriod
during war mweather ,e.g. using the con-
venience opening feature (Y page84). This
wil lspeed up the cooling process and the
desired vehicle interior temperatur ewill be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filter sout pollen.
Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observ ethe
interval for replacing the filter ,which is
specifie dinthe Servic eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Servic eBooklet.

Do not mix fuel ssuch as this with petrol
and do not use any additives. Doing so may
cause engine damage. This does not
include additives for the removal and pre-
vention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz. More information about
recommended additives can be obtained
from any Mercedes-Ben zService Centre.
! Use afilter when adding fuel from afuel
can. The fuel lines and/or the diesel injec-
tion system could otherwis ebeblocked by
particles from the fuel can.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10 compatible. You can
refuel your vehicle using E10 premium-
grade petrol.
i If the recommended fuel is not available,
but only as atemporary measure, you may
also use regula runleaded petrol,
91 RON/82.5 MON. Thi smay reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause
deposits to build up. In consultation with a
Mercedes-Ben zService Cent re,this petrol
ma ybem ixed with the additive recommen-
ded by Mercedes-Ben z(part no.
A0009 89254510). Yo umust observe the
notes and mixin gratios specified on the
container.
For further information on "Fuel", see
(Y page 374). !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conform stoEuro- pean standar
dEN2 28or an equivalent
specifi cation.
You can otherwise impair engine output or
damage the emission contro lsystem.
i In some countries, the available petrol
may not be sufficiently low in sulphur. This
fuel can temporarily produce unpleasant
odours, especially on short journeys. As
soo nassulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced. Diesel (EN 590)
Fuel grade !
When refuelling, only use diesel fuel that
confor ms to th eEuropean standard EN 590
or is of equivalent quality. You can other-
wise impair engine output or damage the
engine.
! Vehicles with diesel particle filters: in
countries outsid ethe EU ,only use low sul-
phu rEuro diesel with asulphu rcontent of
under 50 ppm. Otherwise, the emission
con trol system coul dbedamaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with ahigher sulphur conten tare avail able,
the vehicle's oil change intervals are
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
compl ywithEN5 90can lea dtoincreased
wear, engin edamag eand damage to the
exhaust system.
Do not use the following:
R marine diesel

WARNING
DISTRONIC PLUS canno ttake account of road
and traffic conditions. If DISTRONI Cdoes not
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
alr eady active, deactivate it. This is especially
the case:
R befor ecorners
R on filter lanes
R when changing to alane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverte d,e.g. at roadworks on amotor-
way
DISTRONIC PLU Sotherwise maintains the
current spe ed setbyyou or accelerates up to
the set speed.
DISTRONIC PLU Scannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONI CPLUS:
R if th eroads are slippery, snow-covered or
icy .The wheels coul dlose their grip when
brakin goraccelerating .The vehicle could
star ttos kid.
R if the sensors are dirty or there is poo rvis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLU Sisactivate d.
Otherwise, you ma yfail to recognise dangers
in time, caus eanaccident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brake syourvehicle up to a
maximu mof4m /s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must als oapply the brakes yourself if this
braking power is not sufficient.
If DISTRONI CPLUS detects arisk of collision
with avehicle in front, an intermit tent warning
tone sounds. In addition, the ·distance
warning lamp in the instrument cluste rlights
up. Brak etoavoidac ollision. G
WAR
NING
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by othe rmeans (e.g. in acar wash or
by towing).
The radar senso rsystem is automatically
deactivated near radio teles cope facilities
(Y page 38 0).
If you want DISTRONIC PLUS to assist you,
the radar sensor syste mmust be activated
(Y page 249 )and operational.
General notes DISTRONIC PLUS regulates the speed and
automati cally helps you maintain the dis-
tanc etot he vehicle detected in front. It
brakes automatically in orde rtoavoid
exceedi ngthe set speed.
On long and stee pdownhil lgradients, espe-
ciall yifthe vehicle is laden or towing atrailer,
yo um ust select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effec tofthe engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
If DI STRONIC PLUS detects aslower-moving
vehicle in front ,your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If ther eisnov ehicle in front ,DISTRONIC
PLUS operate sinthe sam eway as cruise
control in the spee drange between
30 km/h and 200 km/h. If avehicle is driving
in fron tofyou, DI STRONIC operates in the
speed range betwee n0km/h and
200 km/h.

Do not use additive sinengine oil .This

Engine oil viscosity Viscosit
ydescribes the flow characteristi cs
of afluid. If an engin eoil has ahigh viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SA Eclassification (viscosity). The table
below shows you which SA Eclassifications are to be used. The low-temperature proper-
ties of engin eoils can be significantly
impaired durin goperation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommende dtoobserve
regula roil changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
