FM
reception

A vehicle isnot anideal place tolisten toaradio.
Because thevehicle moves, reception conditions
are constantly changing.
Buildings, terrain,signaldistance andnoise from
other vehicles areallworking againstgoodrecep-
tion. Some conditions ofFM may appear tobe prob-
lems when theyarenot.
The following characteristics arecompletely nor-
mal foragiven reception area,andthey donot In-
dicate anyproblem withtheradio itself.

Note
Electronic accessories shouldonlybeinstalled by
your authorized Porschedealer.
Equipment whichhasnotbeen tested andap-
proved byPorsche mayimpair radioreception.
Fading
anddrifting

FM range islimited toabout 25miles (40km),
except forsome highpower stations.
If avehicle ismoving awayfromthedesired sta-
tion's transmitter, thesignal willtend tofade and!
or drift. Thiscondition ismore prevalent withFM
than AM,andisoften accompanied bydistortion.
Fading anddrifting canbeminimized toacertain
degree bycareful attention tofine tuning orselec-
tion ofastronger signal.

Static andfluttering

When theline-{)f-sight linkbetween atransmitter
and vehicle isblocked bylarge buildings ormoun-
tains theradio sound maybeaccompanied with
stati~ orfluttering becauseofthe characteristic of

FM.

In asimilar effect,afluttering noiseissometimes
heard whendriving alongatree-lined road.
This static andfluttering canbereduced byadjust-
ing the tone control forgreater bassresponse un-
til the disturbance haspassed.
Multipath

Because ofthe reflecting characteristics ofFM,
direct andreflected signalsmayreach theanten-
na atthe same time(multipath) andcancel each
other out.
As avehicle movesthrough theseelectronic dead
spots, thelistener mayhear amomentary flutter
or loss ofreception.

Station swapping

When twoFMstations areclose toeach other, and
an electronic deadspot, suchasstatic ormulti-
path area, interrupts theoriginal signal,some-
times thestronger secondsignalwillbeselected
automatically untiltheoriginal onereturns.
This swapping canalso occur asyou drive away
from theselected stationandapproach another
station ofastronger signal.

during longtrips, check thatRoof Transport
System andload aresecure.
Retighten ifnecessary andsecure additionally

Nevertheless, Porscherecommends thatyou
do not exceed theposted speedlimit.

Fuels
containing MMT

Some NorthAmerican fuelscontain anoctane en-
hancing additive calledmethylcyclopentadienyl
manganese tricarbonyl(MMT).

If
such fuels areused, youremission controlsys-
tem performance maybenegatively affected.
The check engine warning lightonyour instrument
panel mayturnon.

If
this occurs, Porsche recommends youstop us-
ing fuels containing MMT.
Portable FuelContainers

/!\
Danger!
Portable fuelcontainers, fullorpartially
empty, mayleakcausing anexplosion, orre-
sult infire incase ofan accident.

D>
Never carryadditional fuelinportable contain-
ers inyour vehicle.

Fuels
containing alcoholandether

Some areasofthe U.S. require oxygenated fuels
during certain portions ofthe year. Oxygenated fu-
els are fuels which contain alcohols (suchasmeth-
anol orethanol) orether (such asMTBE).
Under normal conditions, theamount ofthese
compounds inthe fuel willnot affect driveability.
You may useoxygenated fuelsinyour Porsche,
provided theoctane requirements foryour vehicle
are met. Werecommend, however,tochange to
a different fuelorstation
if
any ofthe following
problems occurwithyour vehicle:
- Deterioration ofdriveability andperformance.
- Substantially reducedfueleconomy.
- Vapor lockandnon-start problems, especially

Toprevent thedoor locks fromfreezing during
the cold season, thelock cylinders shouldbe
covered duringawash.

t>
Should thelocks freeze, useanordinary de-
icer. Inmany cases, awell warmed keycan
help. Never useexcessive force.

Paint

t>
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.

Maintenance, CarCare Preservation
The paint surface becomes dullover timedueto
weathering. Itis therefore necessary topreserve
the paint regularly.
This keeps thepaint shiny andelastic. Dirtispre-
vented fromadhering tothe paint surface andin-

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.
