Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a incor-
rect refuelling guard » Fig. 179. This guard means it is only possible to refuel 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.
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. Do not continue filling the
fuel tank otherwise the expansion volume is filled up.
Be careful when filling diesel fuel from the spare canister – danger of contami-
■
nating 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 fu-
elling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, containing a reserve of approx.
7 litres.
Unleaded petrol

First read and observe the introductory information and safety warn-
ings on page 212.
Your vehicle can only be operated with unleaded petrol in compliance with the
EN 228 standard.

All petrol engines can be operated using petrol that contains at most 10% bioe-
thanol (E10).

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.
Required fuel - unleaded petrol 95/91 or 92 or 93 RON

Fuel additives
Unleaded petrol in accordance with the EN 228 standard
tions for a smooth-running engine. We therefore recommend that no fuel addi-
tives are used. This can result in considerable damage to parts of the engine or
the exhaust system.
CAUTION
Even filling the tank with leaded petrol that does not meet the standards once
■
can lead to serious damage to parts of the exhaust system!

If a fuel other than unleaded fuel which complies to the above mentioned
■
standards (e.g. leaded petrol) is used by mistake, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We recom-
mend that you have the fuel system cleaned by a specialist garage.
