Refueling Fires Cellphones
The RF energy from a cellphone can cause a sparking on bare metal, much like aluminum foil in a microwave oven. The spark could ignite gasoline fumes present while refueling.
Do not use a cellphone while pumping gas.
Refueling Fires Static Electricity
Static discharge from your body can ignite gasoline fumes present when you get back out of the vehicle and touch the fuel nozzle.
Do not re-enter the vehicle while pumping gas.
Risk of fire during refueling
Fuel is highly flammable, can deflagrate or explode.
Fuel vapors and skin contact with fuel
Fuel and fuel vapors are harmful to health.
To prevent damage to the emission control system and engine:
In some cases, fuels have a high sulfur content. As a result, under certain driving conditions, combustion in the engine can lead to output of unpleasant odors (known as the "odor of rotten eggs"). Porsche is not responsible for this circumstance and it does not indicate a vehicle fault.
The contents of the tank are displayed on the instrument panel when the ignition is switched on.
If an amount less than the model-dependent residual quantity remains in the fuel tank, the warning light on the multifunction display in the instrument panel lights up when the ignition is switched on or the engine is running.
Selecting suitable fuels
Unsuitable fuels may damage the engine as well as the fuel and exhaust system.
Information regarding fuel quality can normally be found on the fuel pump. Service station employees can also provide information.
Unleaded fuels may not be available outside the continental U.S. and Canada.
The engine is optimally designed for unleaded fuels without metallic additives.
The engine is suited to operation with fuel containing up to 15% ethanol. The use of fuels containing ethanol may lead to an increase in fuel consumption.
If the recommended fuel is not available, in an emergency, the vehicle can also be fueled using unleaded fuel without metallic additives, with octane levels of 91 RON/82.5 MON (86 CLC or AKI). However, this may reduce performance and increase fuel consumption.
