Care of windshield wiper blades
Windshield wiper blades that are in perfect
condition are vital for a clear view.
f
Please see the chapter “WIPER BLADES” on
page 261.
f
Have the wiper blades replaced twice per year
(before and after the cold season) or if wiper
performance deteriorates or the blades are
damaged.
f
Clean the wiper blades with window cleaner at
regular intervals, especially after washing the
vehicle in a car wash.
We recommend Porsche window cleaner.
If wiper blades are very dirty (e.g. covered with
insect remains), they can be cleaned with
a sponge or cloth.
If the wiper blades rub or squeak, this may be due
to the following:
– If the vehicle is washed in an automatic
car wash, wax residues may adhere to
the windshield. These wax residues can
be removed only by using window
cleaner concentrate.
f
Please see the chapter “WASHER FLUID” on
page 259.
Contact your authorized Porsche dealer for more
information.
– The wiper blades may be damaged or worn.
f
Have damaged wiper blades replaced
immediately.
Undercoating
The underside of your car is durably protected
against chemical and mechanical influences.
As it is not possible to exclude the risk of damage
to this protective coating in day to day driving, it
is advisable to have the underside of the car
inspected at certain intervals - preferably before
the start of winter and again in spring - and the
undercoating restored as necessary.
Your authorized Porsche dealer is familiar with the
bodyseal treatment procedures and has the
necessary equipment for applying factory
approved materials. We recommend that you
entrust them with such work and inspections.
Unlike conventional spray oils, undercoating and
rust-proofing compounds based on bitumen or
wax do not attack the sound-proofing materials
applied at the factory.
Warning!
Danger of fire resulting in serious personal
injury or death.
f
Do not apply additional undercoating or rust-
proofing on or near the exhaust manifold,
exhaust pipes, catalytic converters or heat
shields. During driving the substance used for
undercoating could overheat and ignite.
f
Before applying fresh underseal, carefully
remove deposits or dirt and grease. Once it
has dried, the new undercoating compound
forms a tough protective coating which
provides efficient rust-proofing of the floor
panels and components.
f
Always apply a fresh coating of suitable preser-
vative to unprotect areas after cleaning the
underside of the body, the transmission, the
engine or carrying out repairs to under-body,
engine or transmission components.
Effective rust-proofing is particularly important
during the cold weather season. If your car is
driven frequently in areas where salt has been
spread on the roads, the whole engine compart-
ment should be cleaned thoroughly after the
winter to prevent salt from causing any lasting
damage. A full under-body wash should also be
performed at the same time.
