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.

rier only inconjunction withthetransverse sup-
porting pipes.

c>
The permissible useableloadof165 Ibs
(75 kg), thepermissible totalvehicle weight
and thepermissible axleloads mustnotbe
exceeded. Please observe thechapter "WEIGHTS" on

Before everyjourney, andatregular intervals
during longtrips, check thatRoof Transport
System andload aresecure.
Retighten ifnecessary andsecure additionally
by locking.

Inthe loaded state,adjust maximum speedto
the nature, sizeandweight ofthe load being
carried.
In no case, however, shouldyoudrive atmore
than 90mph (140 km/h).

With thebasic carrier installed andnoload, do
not exceed amaximum speedof110 mph
(180 km/h) sincedriving stability willbead-

Adapt yourdriving styleandspeed tothe
changed conditions.
Nevertheless, Porscherecommends thatyou
do not exceed theposted speedlimit.

Driving, brakingandsteering behavior ofthe
vehicle change duetothe higher center of
gravity andthegreater wind-resistant area.
You should adaptyourdriving styleappropri-
ately.

Octane ratings

The CLC orAKI octane ratingisusually lowerthan
the RON rating:
For example: 95RON equals 90CLC orAKI
Unleaded
fuelsmaynotbeavailable outsidethe
continental U.S.andCanada. Therefore, werec-
ommend youdonot take your cartoareas or
countries whereunleaded fuelmay notbeavail-
able.
Octane ratingindicates afuel's ability toresist det-
onation. Therefore, buyingthecorrect octanegas
is important toprevent engine"damage".
The RON octane ratingisbased onthe research
method. TheCLC (U.S. CostofLiving Council oc-
tane rating) orAKI (antiknock index)octane rating
usually displayed onU.S. fuelpumps iscalculated

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
at high altitude orathigh temperature.
- Engine malfunction orstalling.
