Minor Repairs

Changing Particle Filters

Regular replacement of the filters is part of
servicing.
Dirty filters can be the cause of reduced air
throughput, e.g. the windows can mist up.
f
Have the filters replaced.
Please contact an authorized Porsche dealer.
Information
The particle filters ensure 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 recirculated-air button.

Tires and Wheels

The original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.
Information
The summer tires of your car have been specially
developed and adapted for high performance. At
low outside temperatures (below 60 °F (15 °C)),
the tire characteristics change. This can result in
noises occurring when parking or maneuvering at
low outside temperatures.
For your safety remember the following:
– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original
equipment wheels, be sure that they conform
to Porsche specifications for your model. Only
tires with the same make and with the same
specification code (e.g. "N0", "N1"...) can be
mounted.
– The use of wheel rims and wheel bolts that do
not meet specifications of the original factory
installed equipment will affect the safe
operation of your vehicle and affect warranty
coverage.
– Before you plan on exchanging wheels, or
snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer.
Your dealer has the technical information
necessary to advise you which wheel rims and
wheel bolts are compatible with the original
factory installations.
