The beginning ofthe redmarks atthe right endof
the scale indicates themaximum permissible en-
gine rpm.
A speed limiterprevents theengine frombeing

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.

HowEmission ControlWorks

When anautomobile engineisrunning, ituses en-
ergy generated throughthecombustion ofamix-
ture ofair and fuel. Depending onwhether acar is
driven fastorslowly orwhether theengine iscold
or hot, some ofthe fuel (hydrocarbons) maynot
be burned completely, butmay bedischarged into
the engine crankcase orexhaust system.Additon-
al hydrocarbons mayenter theatmosphere
through evaporation offuel from thefuel tank.
These hydrocarbons
(He),
when released intothe
air, contribute toundesirable pollution.
In addition, carbonmonoxide (CO)andoxides of
nitrogen (NOx)contribute toengine emissions.
They, too,areformed duringthecombustion pro-
cess anddischarged intotheexhaust system.
To reduce thesepollutants, yourPorsche is
equipped withaprecisely calibrated fuelinjection
system toassure afinely balanced air/fuelmixture
under alloperating conditions.
Oxygen
sensor

The oxygen sensor, installed inthe exhaust pipe
continuously sensestheoxygen content ofthe
exhaust andsignals theinformation toan electron-
ic control unit.Thecontrol unitcorrects theair/
fuel ratio, sothe engine always receives anaccu-
rately metered air/fuelmixture.

Crankcase ventilation

Through crankcase ventilation, undesirable emis-
sions fromtheengine crankcase arenotpermit-
ted toreach theoutside atmosphere. Theseemis-
sions arerecirculated fromthecrankcase tothe
air intake system. Fromheretheemissions mix
with theintake airand arelater burned inthe en-
gine.

Catalytic converters

The catalytic converters areefficient "clean-up"
devices builtintotheexhaust systemofthe vehi-
cle. The catalytic converters burntheundesirable
pollutants inthe exhaust gasbefore itis released
into theatmosphere.

The exclusive useofunleaded fueliscritical-
ly important forthe lifeofthe catalytic con-
verters. Therefore, onlyunleaded fuelmust
be used. The
catalytic converters willbedamaged by:

- push ortow starting thevehicle
- misfiring ofthe engine
- turning offthe ignition whilethevehicle ismov-
ing or
- driving untilthefuel tank iscompletely empty
- byother unusual operating conditions.

t>
Donot continue tooperate yourvehicle under
these conditions, sincerawfuelmight reach
the catalytic converters. Thiscould result in
overheating ofthe converters. Federallawpro-
hibits useofleaded fuelinthis car.
