WARNING■The auxiliary heating (auxiliary heating and ventilation) (hereinafter refer-
red to as aux. heating) must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, do not switch off the car in pla-
ces where the exhaust fumes can come into contact with flammable mate-
rials such as dry grass, undergrowth, leaves, spilled fuel etc. -. risk of fire.
CAUTION
■ The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.■
If the auxiliary heating is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
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
or

After switching off the auxiliary heating, the coolant pump still runs for a short
period.

Introduction
This chapter contains information on the following subjects:
Petrol and diesel refuelling
160
Lead-free petrol
161
Diesel fuel
162
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap » Fig. 163 on page 160 .
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.
■
Fuel vapours are explosive - can be fatal!
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.

Refuelling can be done if the following conditions are met. The vehicle is unlocked.
The engine and the ignition are switched off.
The auxiliary heating and ventilation is switched off » page 110.

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, these canisters can become dam-
aged 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.
NoteThe fuel capacity for vehicles with front wheel drive is about 55 litres, and for
vehicles with four-wheel drive about 60 litres, with about 9 litres as reserve.
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 160 first.
The vehicle can only be operated with unleaded petrol in compliance with the
EN 228 1)
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 and exhaust emissions. 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 and exhaust emissions. 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 box under 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 165.■
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.
