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.

TUS OF LEVEL CONTROL” on Page 154.
