Washer Fluid - Porsche Cayenne 2009 Owner's Manual

Changing the brake fluid
Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boi-
ling point and, under certain operating conditions,
can affect the braking performance.
f Therefore, have the brake fluid changed in
accordance with the change intervals stated in
the "Maintenance" booklet.
