226 Checking and refilling levels
WARNING (continued)
− For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could be damaged in an accident
and leak.
•
If, in exceptional circumstances, you have to carry a spare fuel canister,
please observe the following points:
− Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This could cause an explosion. Always place the canister on the
ground to fill it.
− 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.
•
When filling the fuel tank after having run it completely dry on a vehicle
with a diesel engine the ignition must be switched on for at least 30 seconds
without starting the engine. When you then start the engine it may take
longer than normal (up to one minute) for the engine to start firing. This is due
to the fact that the fuel system has to purge itself of air before starting.
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 recommended fuel types are listed on a sticker inside the
fuel tank flap.
Only unleaded petrol conforming to 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
= "Research 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.
The correct fuel type for your vehicle is given in the technical table for the
engine, in the Technical Specifications section.
Caution
•
Petrol with standard EN 228 may be mixed with small quantities of
ethanol. However, the 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 tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.
