Checking and refilling levels
167
Petrol types are categorised according to their octane number, e. g. 91, 95,
98 RON (RON = “research octane number”). You may use petrol with a higher
octane number than the one recommended for your engine. However, this
has no advantage in terms of fuel consumption and engine power.
WARNING (continued)
− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
Caution
•
Even one tankfull of leaded fuel would permanently impair the efficiency
of the catalytic converter.
High engine speed and full throttle can damage the engine when using
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.

Petrol additives
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
Petrol additives improve the quality of the petrol.
The quality of the petrol influences running behaviour, performance and
service life of the engine. For this reason you should use good quality petrol
containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
Petrol
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.
Petrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.
Only unleaded petrol, corresponding to the standard DIN EN 228 may be
used for vehicles with catalytic converters (EN = “European Norm”).
