Fuel

Warning!
Fuel is highly flammable and harmful to
health.
f Fire, open flame and smoking are prohibited
when handling fuel.
f Avoid contact with skin or clothing.
f Do not inhale fuel vapours.
To prevent damage to the emission control
system and engine:
f Never drive the tank completely out of fuel.
f Avoid high cornering speeds after the warning
lights have come on.
To avoid permanent damage to the functionality of
the catalytic converters and oxygen sensors, use
only unleaded fuel.
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON is used.
If unleaded premium fuels with octane numbers of
at least 95 RON/85 MON are used, the en-
gine's knock control automatically adapts the igni-
tion timing.
The emission control system can be damaged in
various ways (e.g. fuelling incorrectly, shortage of
fuel, tow-starting).
f Please observe the chapter "HOW EMISSION
CONTROL WORKS" on Page 299.
f Please observe the chapter "DISPLAYING STA-
TUS OF LEVEL CONTROL" on Page 154.
