Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating con ditions,
can affect braking performance.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the bro-
chure “Maintenance”. The brake-fluid warning lights in the instrument
panel and on-board computer indicate:
– brake-fluid level too low,
– in conjunction with large pedal travel, braking-
circuit failure.
If the warning lights should light up while
driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.

Check engine warning light
If the warning lights in the instrument panel and on-

Fuels containing MMT Some North American fuels contain an octane en-
hancing additive called methylcyclopentadienyl
manganese tricarbonyl (MMT).
If such fuels are used, your emission control sys-
tem performance may be negatively affected.
The check engine warning light on your instrument
panel may turn on.
If this occurs, Porsche recommends you stop us-
ing fuels containing MMT.
Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak causing an explosion, or re-
sult in fire in case of an accident.
fNever carry additional fuel in portable contain-ers in your vehicle.
