Adding Washer Fluid - Porsche Cayenne Turbo Driver Manual

Changing the brake fluid
Brake fluid absorbs moisture from the air over
time. The absorbed water can impair braking
efficiency.
f Therefore, have the brake fluid changed in
accordance with the change intervals stated in
the booklet "Guarantee and Maintenance".
Warning light and warning
message
The warning light on the instrument panel and the
warning message on the multi-purpose display of
the instrument panel
– indicate that the brake fluid level is too low.
– could indicate a braking circuit failure if the
brake pedal travel is greater than normal.
Note on operation
If the warning lights should light up while driving:
f Stop immediately in a suitable place.
f Do not continue driving.
Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
