WABNING
Do not apply any undersealing on or near
exhaust manifold, exhaust
pipe,
catalytic
converter
or
heat shields.
With the engine
running, tha matetial
may
overheat and ig-
Always apply
a
fresh coating of suitable
pre-
servative to unprotected areas after cleaning
the
underside
ot the
body
or
the engine or
carrying
out
repairs
to
underbody compo-
nents.
Llght lenses and plastlcs
Use
only
soap
and
water
solution ror
clean-
ing the plastic light
lenses. Never use chemi-
cal
cleaning agents
for
this
purpose.
The
same applies to
other plastic
parts and plas-
tic
films.
Ooor,
rogl, and window seals
Rubber
seals
tend to
age
and
become
brittle
or crack if they are not treated occasionally
with glycerine
or
talcum powder.
Light alloy wheels
Pitting
may occur
i,
metallic particles which
cause
contact corrosion
(e.
g.
brass
or cop-
per in
brake dust) are allowed
to
remain on
the aluminium for
too
long.
Regular care is necessary in order
to
retain
the
attractive surface Iinish. The
wheels
should be washed down with a
sponge or
wash brush about every two weeks- ln areas
where salt
is spread on
winter
roads or there
is a lot of
airborne
industrial dust, it
is best
to
clean the wheels weekly.
The Porsche Light Alloy
Wheel Cleaner (pH-
value 9.5) can be used
for this purpose.
ll the pH-value
ol the detergent ls lncorrect,
the
proleclive
coating
on
the wheels will
be
destroyed.
Every
three
months
you
should coat
the
wheels with
a
non-corrosive grease
(vase-
line) alter cleaning.
Using a clean cloth tho-
roughly rub the grease
into the surface.
Polishes
whlch dissolve oxldes, as
fre-
quenlly
used
for other
metals, or
abtasive
lools
or
agents are
unEuitable
because
lhey break down the
oxide
lllm
of the
pro.
lectlve
coating and will
cauae
discolorallon
of the wheel.
Leather care
Leather
is
a
natural
material.
The
tanned
hide is a
product ol
nature. The natural
sur-
face'markings
of
leather
skins, such
as
creases, healed scratches,
insect
bites,
structural differences
and
slighl variations
in
shade
and grain add
to
the attractiveness
of
the real lealher product.
We recommend that the leather
be
treated or
cleaned initially after the
lirst
few
weeks
or
after the car
has covered
a few
thousand
miles. Only
by
doing
so can
the leather pati-
na,
which
emphasizes
the inherent qualities
of
the
leather upholstery, begin
to form.
Cleaning
is
best performed
with
a
white, soft
woolen cloth and
a
cleaning agent with
a
neutral soap basis
(mild soap
and
water
so-
lution).
lf
the
leather
is
heavily
soiled
the
Porsche Cockpit
Cleaner
can also be
used.
Please
follow the instructions on the
con-
tainers carelully.
Do
not
use
aggressive cleaner
or
hard
ob-
jects.
Take
special care not
lo
dampen
the
other
side
of the perforated
leather trims.
Once
you
have
cleaned the leather (especial-
ly the heavily used leather
seats)
treat
it
with
the
Porsche Leather
Care Agent.
Leather
should be cleaned and treated several times
a year, depending on how quickly
it
be-
comes dirty.
Should the leather become damaged during
use (e. g. when
transporting
sharp objects
or
iI tools etc. should slip) the
damage can
be
made less conspicuous
using the
Porsche
Leather Color
Coating.
Fabric, upholstely and carpets
Use only
a
vacuum cleaner or a medium stiff
brush. Remove stains
and
spots
with
Porsche stain remover.
