Changing particle filter
Regular replacement of the filter is part of
servicing.
A dirty filter can be the cause of reduced air
throughput.
f
Have the filter replaced.
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.
Note on operation
The particle filter ensures that the fresh air
entering the passenger compartment is virtually
free of dust and pollen.
f
If the outside air is polluted by exhaust fumes,
press the circulating-air button.
Power steering
Warning!
Risk of accident. When the engine is
stationary (e.g. when on tow) or the hydraulic
system fails, there is no assistance for
steering.
Therefore, substantially more force will have
to be exerted in order to steer.
f
Exercise great care when on tow.
f
Have the fault remedied. 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.
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the
steering system.
Checking and adding hydraulic fluid
Observe the following points:
f
Only use genuine Porsche hydraulic fluid or a
hydraulic fluid of similar quality which has been
approved according to Porsche specifications
and product requirements.
f
Check the fluid level with the engine stopped
and cold (engine temperature approx.
