! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After yo uhave
heated or ventilated the vehicle amaximum of
two times ,drive for alonger distance.
i Switch the auxiliary heating on regularly –

WARNING
Very ho torvery cold air can flow from the air
vents. This coul dresult in burns or frostbite in
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicl eoccupants always
maintai nasufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicl einterior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet betwee nthe windscree nand
the bonnet free of blockages, such as ice,
snow or leaves
R never cover the vents or ventilation grilles in
the vehicle interior
i For virtually draught-free ventilation, adjust

X Turn the key back to position gin the ignition lock before attempt-
ing to start the engine again.
X Restart the engine (Y page 96). Avoid excessively long and frequent
attemptstos tart the engine, as this (Y page 96) will drain the bat-

0. The fuel tank is empty.
X Refuel the vehicle.
X Bleed the fuel system (Y page 110).The engine does not
start
.You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 227).
If the engine does not start despite attempt stojump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to excessively high thermal load.
X Allow the starter motor to cool down for approximately two minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult aqualified specialist workshop. The coolant temperature
display is showing more
than 120 †. Adisplay
message may also
appear in the multifunc-
tion display and awarn-

being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 215). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolan
tlevel is correct, the radiator fan may be faulty. The cool-
ant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below1 20 †, you can continue driving
to the nearest qualifieds pecialist workshop.
X Avoid heavy loadsont he engine as you do so, e.g. driving in moun-

WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel.W hen the engine is running,
components in the exhaust system may over-
heatu nnoticed. There is arisk of fire.
Never refue lwith petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality .Fuel that does not
conform to EN 590 can leadtoi ncreased wear
as wellasd amage to the engine and 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 such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehiclesw
ith diesel particle filters: in
countries outside the EU, only use low sulphur
Euro diesel with asulphurc ontent of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
You will usually find information aboutt he fuel
quality on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 109).
Low outside temperatures In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitablef or operation in colder
climatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com- panies, e.g. at filling stations. AdBlue
