Information
If the recommended fuel is not available, the vehicle
can also be fueled in an emergency with unleaded
metal-free fuel, with octane levels of 91 RON/82.5
MON (86 CLC or AKI). However, this may reduce
performance and increase fuel consumption.
e
Refuel with unleaded metal-free fuel, with oc-
tane levels of at least 91 RON/82.5 MON.
e
Do not drive with full throttle with unleaded fuel
with octane levels of 91 RON/82.5 MON (86
CLC or AKI).
Using additives with lower fuel quality
NOTE
Unapproved additives can damage the engine as well
as the fuel and exhaust system.
e
Only use additives that have been approved by
Porsche.
Fuel deposit characteristics may not meet require-
ments in some countries. In this case, following con-
sultation with an authorized Porsche Partner dealer,
the fuel may be mixed with an additive sold and
recommended by Porsche: Porsche part number 000
043 209 02.
e
Observe the instructions and mixing ratios
specified on the container.
e
Observe maintenance intervals, particularly oil
change intervals.

Roadside Assistance
Filler flap emergency release

filler flap can be opened manually:
1. Open the passenger's door.
2. Pull up the knob in the right-hand door cut-out.
�� The filler flap is unlocked.
Fuel vapor restraint system
Vent valve for fuel tank
The evaporation chamber and the carbon canister
prevent fuel vapors from entering the atmosphere at
very high outside temperatures if the vehicle is driven
rapidly through bends or has been parked off-level.
Fuel vapor restraint system and storage
During refueling, the vapors collect in the evaporation
chamber. The vapors enter the carbon canister via a
vent line. They are stored there for as long as the
engine is not running.
Flushing system
When the engine is running, the fuel vapors from the
container are mixed with fresh air from the ambient
air of the container. This mixture reaches the intake
tract via the tank vent line, is mixed with intake air
and burned during the normal combustion process.
