Open the protective cap.
Use the ignition key to unlock
the fuel filler cap and pop the
cap open.
Fuel expands when hot.
Fuel escaping from an
overfilled tank could make its way
onto the road surface. This could
cause a fall.
Do not overfill the fuel tank.
Leaded fuel will destroy the
catalytic converter.
Use only unleaded fuel.
Refuel with fuel of the grade
stated below; do not fill the
tank past the bottom edge of
the filler neck.
When refuelling after run-
ning on reserve, make sure
that you top up the tank to a
level above reserve, as other-
wise the sensor will not be able
to register the new level. If the
sensor cannot register the new
level neither the fuel-level read-
ing nor the range readout can be
updated.
