Note
Door windows feature a water-repellent (hydro-
phobic) coating which prevents soiling of the 
windows. 
This coating is subject to natural wear and can be 
renewed.
fConsult an authorized Porsche dealer.Wiper blades Wiper blades that are in perfect condition are vital 
for a clear view.
fPlease see the chapter “WIPER BLADES” on 
Page 212.
f Replace the wiper blades twice per year (be-
fore and after the cold season) or whenever 
wiper performance deteriorates or the blades 
are damaged. 
f Periodically clean the wiper blades with 
Porsche window cleaner, especially after the 
vehicle has been washed in a car wash.
If they are very dirty (e.g. with insect remains), 
they can be cleaned with a sponge or cloth. 
If the wiper blades rub or  squeak, this can be as a 
result of the following:
– If the vehicle is washed in an automatic car  wash, residues may adhere to the windshield. 
These wax residues can be removed only by 
using window cleaner concentrate. 
– The wiper blades may  be damaged or worn. – Replace damaged or worn wiper blades imme-
diately.
f Please see the chapter “WASHER FLUID” on 
Page 210.
f Please contact your authorized Porsche dealer 
for further information.
Undercoating As it is not possible to ex clude the risk of damage 
to this protective coating in  day to day driving, it 
is advisable to have the  underside of the car in-
spected at certain interv als – preferably before 
the start of winter and again in spring – and the un-
dercoating restored as necessary. 
Your authorized Porsche dealer is familiar with the 
bodyseal treatment procedures and has the nec-
essary 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 so und-proofing materials ap-
plied 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, ex-
haust pipes, catalytic converters or heat  shields. During driving the substance used for 
undercoating could overheat and ignite. 
f Before applying fresh underseal, carefully 
remove any deposits of 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 pre-
servative to unprotected 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 seas on. If your car is driv-
en frequently in areas where salt has been spread 
on the roads, the whole engine compartment 
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.
Stainless steel exhaust tailpipesStainless steel exhaust tailpipes can discolor due 
to soiling, strong heat, and combustion residues.
The original polish can be achieved again using 
commercially available metal polishing paste or 
metal polish.
