Car care instructions

Regular and correct care helps to maintain
the value of your car and is also a precondi-
tion for the long-life guarantee.
Washing
The best method of protecting your car from
the damaging effects of the environment is
frequent washing and the re-application of a
preservative.
The salt spread on winter roads, road dust
and dirt, airborne industrial emissions, dead
insects, bird droppings etc. can have a da-
maging effect on the bodywork if allowed to
remain on the car for a long time.
Salts have a particularly corrosive effect on
body seams, flanges and joints.
It is therefore necessary to clean such areas
thoroughly with a sponge when you wash
the car - or after going through an automa-
tic car wash, then rinse them with water and
rub dry with a leather.
New cars should be washed carefully with
plenty of clear water to protect the fresh
paintwork. Dark paint finishes show up the
smallest of surface damage (scratches) mo-
re readily than light colors. Dark colors are
also slightly more susceptible to scratches
because the composition of their pigments
and therefore require special care and at-
tention.
Use an abundant supply of water, a soft
sponge or wash brush and a suitable, mild
car shampoo. Begin by spraying the body
thoroughly with water to rinse away loose
dirt. Do not wash your Porsche in bright sun-
light or while the bodywork is still hot. After
washing, rinse the car plenty of water and
then leather dry. Remember to clean the
seams, flanges and joints!
Do not use the same wash leather for rub-
bing down as you use for cleaning the wind-
shield and windows.
The moisture which gets on to the brakes
during a car wash can reduce braking effi-
ciency or make the brakes pull unevenly. Al-
ways test the brakes a few times after wash-
ing your car to make sure they are properly
dried off.
Dust should never be wiped off the car with a
dry cloth since dust particles are abrasive
and could dull and damage the surface fin-
ish.
Preservation
The paintwork contains certain fats which
maintain its high lustre and prevent it be-
coming brittle. Climatic effects can remove
these fats from the paintwork. This should be
counteracted by applying a paint preservati-
ve in good time to restore the fats and thus
retain the high lustre.
Please use only the preservatives and wash-
ing agents recommended by your Porsche
dealer. Provided it is washed and treated
with preservative regularly, the brand new
finish of your car will be retained for years to
come. Apply the paint preservative after the
car wash and polish it dry to obtain a bright
finish or simply add a preservative to the fi-
nal rinse water and rub down with a leather.
Polishing
The use of polishes is recommended only af-
ter it becomes evident that the normal pre-
servatives no longer produce the desired fi-
nish.
Caution: Do not apply silicone polishes to
the windshield or windows.
The paintwork of your car is exposed to all
manner of mechanical and chemical stres-
ses, particularly climatic ones such as bright
sunlight, rain, frost and snow. Ultraviolet
light, rapid changes in temperature, rain,
snow, industrial dust and chemical deposits
constantly attack the paint which is only ab-
le to withstand such exposure in the long
term if it is given regular care and attention.
Matt painted parts should not be treated
with preservatives or polishes as this will
spoil the matt effect.
