Alfa Romeo 159 Owner's Handbook Manual page 127

The car must only be
filled with diesel fuel for
motor vehicles, in com-
pliance with European Standard
EN590. The use of other prod-
ucts or mixtures may irrepara-
bly damage the engine with in-
validation of the warranty due
to the damage caused. In the
event of accidentally filling with
another type of fuel, do not
start the engine and empty the
tank. If the engine has been run
even for only a very short time,
in addition to the tank, it is al-
so necessary to drain out the
whole fuel circuit.
REFUELLING
To guarantee full tank filling, carry out
two refuelling operations after the first
click of the fuel delivery gun. Avoid fur-
ther topping up operations that could
cause damages to the fuel system.

FUEL FILLER CAP
The fuel filler cap is unlocked when cen-
tral door locking is off and it is auto-
matically locked when activating the
central door locking.
Opening
Open the flap A-fig. 109 by means
of front part (see figure), turn cap B an-
ti-clockwise and extract it. The cap has
a device C retaining it to the flap so it
cannot be lost. When refuelling, attach
the cap to the flap, as illustrated.
Closing
Fit cap B in its housing and turn it clockwi-
se until it clicks once or more, then close
the flap A.
When refuelling, position the cap on the
device inside the flap as shown in the
figure.

IMPORTANT The sealing of the tank
may cause light pressurising in the tank.
A little breathing off, while slackening
the cap, is absolutely normal.
