WARNING
contact with fuel.
Fuel and fuel vapours are harmful to health.
e Do not inhale fuel vapours.
e Avoid contact with skin or clothing.
Information
Some fuels have a high sulphur content. Combustion
in the engine can therefore cause unpleasant odours
under certain driving conditions (so-called "rotten
egg smell"). Porsche is not responsible for this
characteristic and it does not point to a defect in the
vehicle.
When the ignition is on, the fuel level is displayed on
the instrument cluster.
If the amount is less than a model-dependent re-
maining quantity, a warning message appears on the
instrument cluster.
e Refuel at the next opportunity.
> Please refer to chapter "Technical Data" on
page 280.
