Note■The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux.
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position

▶ Via an automatically programmed and activated pre-set time in the Infotain-
ment.
▶ Automatically when the warning light
in the instrument cluster illumi-
nates.
▶ Automatically according to the ambient conditions »
.
After switching the system off, the auxiliary heating will continue running a lit-
tle while longer in order to burn the remaining fuel in the auxiliary heater.
After switching off, coolant pump still runs for a short period.

The correct fuels for your vehicle are specified on the inside of the fuel filler
flap » Fig. 199 on page 189 .
WARNING■
The operating instructions of the refuelling system must always be fol-
lowed.■
Do not smoke when refuelling and do not use a mobile phone.
■
The fuel and fuel vapours are explosive - risk to life!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

Close the fuel filler flap until it clicks into place.
Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a in-
correct refuelling guard » Fig. 200. This guard means it is only possible to re-
fuel with the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to
and fro with slight pressure to insert it correctly.
WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident this can get damaged and fuel may
escape – risk of fire!
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect
fuelling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, including a reserve of approx.
6 litres .Lead-free petrol
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 189 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Unleaded petrol 95/91 or 92 or 93 RON/ROZ
We recommend using unleaded fuel with an octane rating of 95 RON. Unlea-
ded petrol with the octane ratings 91, 92 or 93 RON can also be used, but may
result in a slight loss in performance and slightly increased fuel consumption.
Unleaded petrol min. 95 RON / ROZ
Use unleaded fuel with the octane rating 95 RON or higher.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »
.
Refuel using petrol of the prescribed octane number as soon as possible.
Unleaded petrol 98/(95) RON / ROZ
We recommend using unleaded fuel with an octane rating of 98 RON or higher.
Unleaded petrol 95 RON can also be used but this results in a slight loss in per-
formance and slightly increased fuel consumption.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »
.
Refuel using petrol of the prescribed octane number as soon as possible.
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2 or E5
for unleaded petrol with octane number 95 and 98.

Some manual skills are required to change a bulb. For this reason, we recom-
mend having bulbs replaced by a specialist garage or seeking other expert help
in the event of any uncertainties.
▶ Switch off the ignition and the relevant lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
A stowage compartment for replacement bulbs is located in a plastic box in
the spare wheel or underneath the floor covering in the luggage compartment.
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the low, high or fog beam.
In case of failure of a xenon gas discharge lamp or an LED diode, visit a special- ist garage.
WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 194.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar. 230Do-it-yourself
