A slight decrease in the fluid level due to wear and
automatic readjustment of the disc brakes is nor-
mal.
If, however, the fluid level falls markedly or below
the “MIN” mark, the braking system may have
developed a leak.
f Have the braking system checked immediately
at an authorized Porsche dealer.
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 conditions,
can affect the braking action.
Therefore have the brake fluid changed in accor-
dance with the change intervals stated in the
brochure “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,
a braking-circuit failure.
If the warning lights should light up while
driving:
f Stop immediately in a suitable place.
f Do not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.
Brake booster warning
The brake booster is monitored, in addition to the
brake fluid level.
If the brake-fluid warning light lights up after
starting the engine, wait to drive until the required
pressure for the brake booster is established and
the warning light goes out.
If the brake fluid warning light in the instrument
panel does not go out, there could be a defect in
the brake booster.
Warning!
Risk of accident due to altered braking
behavior.
f Adjust your speed accordingly for longer
braking distances, higher required pedal
pressures, and altered braking behavior.
f Drive carefully to an authorized Porsche
dealer.
