Washing

The best method ofprotecting yourcarfrom the
damaging effectsofthe environment isfrequent
washing andtheapplication ofapreservative. The
underside ofyour vehicle shouldalsobewashed
thoroughly, atthe latest whensaltisno longer
spread onthe roads.
The longer salt,road dustandindustrial dust,
dead insects, birddroppings orsubstances from
trees (resin, pollen) areallowed toremain onthe
bodywork, themore serious istheir harmful ef-
fect.
New cars should bewashed carefully withplenty
of clear water toprotect thenew paint work. Dark
paint finishes showupthe smallest ofsurface
damage (e.g.,scratches) morereadily thanlighter
colors.
Dark colors arealso more susceptible toscratch-
ing because ofthe composition oftheir pigments
and require particularly carefulpaintcare.

D-
Donot wash yourcarinbright sunlight orwhile
the bodywork isstill hot.

D-
When washing byhand, useabundant water,a
soft sponge orwash brush, andPorsche car
shampoo.

D-
Begin byspraying thebody thoroughly withwa-
ter torinse away loose dirt.
D-

After washing, rinsethecarwith plenty ofwa-
ter and then drywith achamois leather.
Do not use thesame chamois leatherfordry-
ing asyou useforcleaning thewindshield and
windows.

/!\
Warning!
Moisture whichgetsontothe brakes during
a car wash canreduce braking efficiency or
make thebrakes pullunevenly whichcould
increase thedanger ofan accident, causing
serious personal injuriesordeath.

D-
Always applythebrakes afew times after
washing thecartotest braking efficiency and
dry the brake discs.
When doingthis,take care nottohamper other
road users behind you(traffic conditions per-
mitting),

Automatic carwashes

Optional add-onpartsorparts which project
beyond thecontours ofthe vehicle maybe

tomatic carwashes.
The
following partsareparticularly
susceptible todamage:

- Windshield wipers(always switchthemoffto
prevent themwiping unintentionally inintermit-
tent operation)
- External telephone antennas(alwaysunscrew)
- Roof Transport System(alwaysremove com-
pletely)
- Rear spoiler
- Wheels (thewider therimand thelower thetire
height, thegreater therisk ofdamage)
- High-gloss wheels(toprevent thesefromget-
ting scratched, donot clean withthewheel-
cleaning brushesofthe carwash).

Never rubadusty carwith adry cloth since
dust particles areabrasive andcould dulland
damage thesurface finish.
The paintwork ofyour carisexposed toall types
of mechanical andchemical conditions, particular-
ly climatic onessuchasbright sunlight, rain,frost
and snow. Ultraviolet light,rapid changes intem-
perature, rain,snow, industrial dustandchemical
deposits constantly attackthepaint which isonly
able towithstand suchexposure inthe long term

if
itis given regular careandattention.

t>
Donot apply silicone polishes tothe windshield
or windows.

t>
Donot treat matt-painted componentswith
preservatives orpolishes asthis willspoil the
matte effect.

comes evident thatthenormal preservatives no
longer produce thedesired finish.
Spots andstains

t>
Remove tarstains, grease, oilspots anddead
insects assoon aspossible withInsect Remov-
er. They cancause discoloration ifallowed to
remain onthe paintwork.

t>
Wash theaffected areaimmediately aftertreat-
ing it. Minor

t>
Have minor paintdamage, suchasscratches,
scores orchips caused byflying stones, re-
paired immediately byyour authorized
Porsche dealerbefore corrosion setsin.
However, ifthere arealready tracesofcorrosion,
they must firstberemoved carefullyandthorough-
ly. Coat thearea witharust-proofing primerand
finish offwith atop coat. Thepaint code andcolor
number arefound onthe vehicle's paintdataplate.

Engine compartment

The engine compartment andthesurface ofthe
engine aretreated withacorrosion-inhibitor atthe
factory.
If degreasing solventsareused toclean theen-
gine compartment orthe engine iswashed down,
the process almostinvariably removesthecorro-
sion-inhibiting coating.Itis then absolutely neces-
sary tohave adurable preservative appliedtoall
surfaces, bodyseams, jointsandassemblies in
the engine compartment. Thisalsoapplies when
corrosion-inhibitor partsarereplaced.

/!\
Caution!

Risk ofdamage tothe generator.

c>
Donot point thecleaning jetdirectly atthe al-
ternator, orcover thealternator.
Effective corrosion-proofing isparticularly impor-
tant during thecold weather season.Ifyour caris
driven frequently inareas where salthasbeen
spread onthe roads, thewhole engine compart-
ment should becleaned thoroughly afterthewin-
ter toprevent saltfrom causing anylasting dam-
age. Afull under-body washshould alsobeper-
formed atthe same time.
Windows

The road dustwhich settles onthe windshield and
windows containsparticles oftire rubber andoil
residue. Theinterior trimandupholstery release
particles, particularly instrong sunlight, whichcol-
lect onthe insides ofthe windows. Thesedeposits
are augmented byimpurities inthe airwhich en-
ters thecarthrough thefresh airvents.

Ifyou useachamois leatherforthe windows,
do not use itfor paintwork asitwill otherwise
pick upacertain amount ofpreservative orpol-
ish and could smear tilewindows andthus im-
pair vision.

c>
Remove deadinsects withthePorsche insect
remover.

Wiper blades

Wiper blades thatareinperfekt condition arevital
for aclear view.

c>
Replace thewiper blades twiceperyear (be-
fore andafter thecold season) orwhenever

to this protective coatinginday today driving, it
is advisable tohave theunderside ofthe car in-
spected atcertain intervals -preferably beforethe
start ofwinter andagain inspring -and theunder-
coating restored asnecessary.
Your authorized Porschedealerisfamiliar withthe
bodyseal treatment procedures andhasthenec-
essary equipment forapplying factoryapproved
materials. Werecommend thatyouentrust them
