Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with an in-
correct refuelling guard » Fig. 294.
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.
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.
Unleaded petrol
Read and observe and on page 257 first.
The correct fuel for the vehicle is specified on the inside of the fuel filler flap
» Fig. 292 on page 257.
The vehicle can only be operated with unleaded petrol containing maximum
10% bioethanol (E10).
Unleaded petrol must correspond to the European Standard EN 228 (in Ger-
many DIN 51626-1 or E10 for unleaded petrol with octane number 95 and 91
or DIN 51626-2 or E5 for unleaded petrol with octane number 95 and 98).
Prescribed fuel 95/min. 92 and 93 RON
We recommend using petrol 95 RON.
Optionally, the petrol 92 or. 93 RON can be used (slight power loss, a slightly
increased fuel consumption).
In an emergency petrol 91 RON can be used (slight power loss, slightly in-
creased fuel consumption) » .
Unleaded petrol min. 95 RON / ROZ
Use at least 95 ROZ petrol.
In an emergency petrol 91, 92 or 93 RON can be used (slight loss, a slightly
increased fuel consumption) »
.
Prescribed petrol 98/(95) RON / ROZ
We recommend using petrol 98 RON.
Optionally, petrol 95 RON can be used (slight power loss, a slightly increased
fuel consumption).
In an emergency petrol 91, 92 or 93 RON can be used (slight loss, a slightly
increased fuel consumption) » .
CAUTION
The following instructions must be observed, otherwise there is a risk of en-
gine damage and damage to the exhaust system.
■
If gasoline is used which is lower than the prescribed octane number, then
continue driving at medium engine speeds and minimum engine load. Refuel
using petrol of the prescribed octane number as soon as possible.
■
Petrol with a lower Octane count than 91 should not even be used in an
emergency!
■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition.
CAUTION
Petrol additives (additives)
■
The unleaded petrol in accordance with the prescribed standards meets all
the conditions for a smooth running engine. Therefore, we recommend that
you do not add any fuel additives to the petrol - there is a risk of engine dam-
age or damage to the exhaust system.
■
The following additives and auxiliary products may not be used - there is a
risk of engine damage or damage to the exhaust system!
■
Additives with metal components (metallic additives), in particular with
manganese and iron content.
■
Fuels with metallic content (e.g. LRP - lead replacement petrol).
Note
■
Unleaded petrol that has a higher octane number than that required by the
engine can be used without limitations.
■
The use of petrol with an octane rating higher than 95 RON in does not re-
sult in either a noticeable increase in power nor lower fuel consumption in ve-
hicles for which unleaded petrol 95/min 92 or 93 RON is specified.
■
On vehicles using prescribed petrol of min. 95 RON, the use of petrol with a
higher octane number than 95 RON can increase the power and reduce fuel
consumption.
