Refuelling
Fuel tank capacity is listed under "Capacities".
Porsche does not recommend the use of fuel ad-
ditives.
Fuel is highly flammable and harmful to
health.
f Please observe the chapter "CAPACITIES" on
Page 286.
1. Important: Stop the engine and switch off the
ignition.
2. Slowly unscrew the tank cap.
Hang the tank cap on the plastic strap of the
filler flap.
3. Insert fuel-hose nozzle fully into the filler neck
with the handle of the fuel-hose nozzle facing
down.
4. Do not add further fuel once the correctly ope-
rated automatic fuel-hose nozzle has switched
off.
Fuel could spray or could run over in warm
temperatures.
5. Replace the tank cap immediately after
refuelling and turn it until you hear it and feel it
engage.
If you lose the tank cap, you must replace it
only with an original part to reduce the pos-
sibility of a fire in the event of a collision.
Note
The oil level is automatically measured during
refuelling.
f Please observe the chapter "OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL"
on Page 111.
