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.

c>
Clean allwindows regularly, insideandoutside,
with Porsche windowcleaner.

c>
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
wiper performance deteriorates.
C>

Periodically cleanthewiper blades with
Porsche windowcleaner, especially afterthe
vehicle hasbeen washed inacar wash.
If they arevery dirty (e.g. withinsect remains),
they canbecleaned withasponge orcloth.

Undercoating

As itis not possible toexclude therisk ofdamage
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
with such work andinspections.
Unlike conventional sprayoils,undercoating and
rust-proofing compoundsbasedonbitumen or
wax donot attack thesound-proofing materialsap-
plied atthe factory.

A
Warning!
Danger offire and serious personal injuries.

t>
Donot apply additional undercoating orrust-
proofing onornear theexhaust manifold, ex-
haust pipes, catalytic converters orheat
shields. Duringdriving thesubstance usedfor
undercoating couldoverheat andignite.

t>
Before applying freshunderseal, carefullyre-
move deposits ordirt and grease. Onceithas
dried, thenew undercoating compoundforms
a tough protective coatingwhichprovides effi-
cient rust-proofing ofthe floor panels andcom-
ponents.

t>
Always applyafresh coating ofsuitable preser-
vative tounprotected areasaftercleaning the
underside ofthe body, thetransmission, the
engine orcarrying outrepairs tounder-body,
engine ortransmission components.
Effective rust-proofing isparticularly important
during thecold weather season.
If
your carisdriv-
en frequently inareas where salthas been spread
on the roads, thewhole engine compartment
should becleaned thoroughly afterthewinter to
prevent saltfrom causing anylasting damage. A
full under-body washshould alsobeperformed at
the same time.

contact corrosion (e.g.brass orcopper inbrake
dust) areallowed toremain onthe aluminum for
too long.

I>
Ifpossible, washthewheels withasponge or
wash brush about everytwoweeks. Inareas
where saltisspread onwinter roadsorthere
is alot ofairborne industrial dust,itis best to
clean thewheels weekly.

frequently usedforother metals, orabrasive
tools oragents areunsuitable becausethey
break downtheoxide filmofthe protective
coating andwillcause discoloration ofthe
wheel.

Every threemonths, aftercleaning, coatthe
wheels withacar wax ornon-<:orrosive grease
(vaseline).
Using aclean cloththoroughly rubthe grease
into thesurface.

Temperature A,8,C

The temperature gradesareA(the highest), Band
C, representing thetire's resistance tothe gener-
ation ofheat anditsability todissipate heatwhen
tested undercontrolled conditions onaspecified
indoor laboratory testwheel.
Sustained hightemperatures cancause themate-
rial ofthe tire todegenerate andreduce tirelife,
and excessive temperature canlead tosudden
tire failure.
The grade Ccorresponds toalevel ofperfor-
mance whichallpassenger cartires must meet
under theFederal MotorVehicle SafetyStandard

No. 109.

mance onthe laboratory testwheel thanthemini-
mum required bylaw.

A
Warning!

The temperature gradeforthis tireisestablished
for atire that isproperly inflatedandnotoverload-

ed.

Excessive speed,underinflation, orexcessive
loading, eitherseparately orincombination, can
cause heatbuildup andpossible tirefailure.
Tire
pressures

A
Warning!
Incorrect tirepressure causesincreased tire
wear andadversely affectsroadhandling.

I>
Always useanaccurate tirepressure gauge
when checking inflationpressures.

I>
Donot exceed themaximum tirepressure list-
ed onthe tire sidewall.
Please observe thechapter "VEHICLE IDENTI-
FICATION, TECHNICAL DATA"onPage 179.

I>
Cold tireinflation pressure means:alltires
must becold, ambient temperature maximum
68°F (20°C), whenadjusting theinflation pres-
sure.
Avoid sunlight strikingthetires before measur-
ing cold pressures, sincethepressures would
rise from temperature influence.

I>
Valve capsprotect thevalve fromdustand
dirt, andthus from leakage.
Always screwcapstightly down.
Replace missingcapsimmediately.

I>
Donot use commercially availablesealantor
tire inflating bottles.
Tire
traction

A
Warning!
When driving onwet orslushy roads,a
wedge ofwater maybuild upbetween the
tires andtheroad. Thisphenomenon is
known as"hydroplane" andmay cause par-
tial orcomplete lossoftraction, vehicle
control orstopping ability.
I>
Reduce speedonwet surface toprevent this.

Tire life

Tire lifedepends onvarious factors, i.e., road
surfaces, trafficandweather conditions, driving
habits, typeoftires andtirecare.

I>
Inspect yourtires forwear anddamage before
driving off.Ifyou notice uneven orsubstantial
wear, wheels mightneedalignment ortires
should bebalanced orreplaced.
