210 Checking and refilling levels
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.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.
Caution
•
Fuel spills should be removed from the paintwork immediately.
•
Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.
For the sake of the environment
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

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 Standard").
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= "Regulation Octane Number, unit for determining the knock resistance of
petrol"). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power. If, in exceptional circumstances, the correct
octane rating is not available:
•
For engines which require Premium unleaded petrol (95 RON) the
following is valid: Regular unleaded fuel with 91 RON can also be used. This
can, however, result in a slight loss of power under certain driving conditions.
•
For engines which require Premium unleaded petrol (98 RON) the
following is valid: Premium unleaded fuel with 95 RON can also be used. This
can, however, result in a slight loss of power under certain driving conditions.
– If premium unleaded petrol is not available, the engine can be run on
regular unleaded petrol with 91 RON as an "emergency measure". In this
case only use moderate engine speeds and a light throttle. Avoid using full
throttle. Fill up with premium petrol as soon as possible.
Caution
•
Petrol that follows EN 228 may be mixed with small quantities of ethanol.
However, the so-called "bioethanol fuels" available at commercial establish-
ments with reference E50 or E85, which contain a high percentage of ethanol,
may not be used, as they will damage the fuel system.
•
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
petrol with an octane rating lower than the correct grade for the engine.
For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.
