FuelQuality
Your engine isdesigned toprovide optimum performance andfueleconomy using
unleaded premiumfuelwith anoctane ratingof98 RON (93CLC orAKI).
Porsche therefore recommends theuse ofthese fuelsinyour vehicle.
Porsche alsorecognizes thatthese fuelsmaynotalways beavailable. Beassured thatyour vehicle willoperate
properly onunleaded premiumfuelswithoctane numbers ofatleast
95RON (90CLC orAKI).
since theengine's "Electronic Oktane™knockcontrol" willadapt theignition timing,ifnecessary.
Fuels containing alcoholandether
Some areasofthe U.S. require oxygenated fuelsduring certain portions ofthe year.
Oxygenated fuelsarefuels which contain alcohols (suchasmethanol orethanol) orether (such asMTBE).
Under normal conditions, theamount ofthese compounds inthe fuel willnot affect driveability.
You may useoxygenated fuelsinyour Porsche, providedtheoctane requirements foryour vehicle aremet.
We recommend, however,tochange toadifferent fuelorstation ifany ofthe following problems occurwithyour vehicle:
- Deterioration ofdriveability andperformance.
- Substantially reducedfueleconomy.
- Vapor lockandnon-start problems, especiallyathigh altitude orathigh temperature.
- Engine malfunction orstalling.
Fuels containing MMT
Some NorthAmerican fuelscontain anoctane enhancing additivecalledmethylcyclopentadienyl manganesetricarbonyl(MMT).
If such fuels areused, youremission controlsystem performance maybenegatively affected.
The check engine warning lightsonyour instrument panelmayturnon.
If this occurs, Porsche recommends youstop using fuelscontaining MMT.

Q)
Warning light
The central triggering unitmonitors theoperation-
al readiness ofthe airbag system andthewarning
light.
Any malfunctions thatmay occur willbeindicated
by the warning lightsinthe instrument paneland
on-board computer.
~ Inthe following casesyoushould immedi-
ately consult anauthorized Porschedeal-
er inorder toassure theairbag system is
functioning properly:
- Illumination ofthe airbag warning lightduring
travel orrepeated illumination longerthan5
seconds aftertheignition circuitisturned on.
- Illumination failstolight upduring ignition
circuit activation.
If the airbags onthe passenger's sideare
switched offbythe
child restraint system,
orif
an installed childrestraint systemisdetected
when theignition isswitched on,the warning light
flashes
for60seconds whentheignition ison.
A
Danger!
If the light does notflash, theairbags arenot
deactivated andachild restraint system
must notbeinstalled.
~ Have thefault remedied immediately byan
authorized Porschedealer.
Airbag
maintenance
In order toensure long-term functioning, theair-
bag system mustbeinspected byan authorized
Porsche dealerafter4,8and 10years fromthe
date ofmanufacture shownonthe safety compli-
ance sticker, andevery 2years thereafter.
Important information
If you sellyour Porsche, notifythepurchaser that

Make itahabit tocheck theoperation ofyour
brakes beforedriving.
Keep inmind thatthebraking distance increases
very rapidly asthe speed increases. At60 mph or
100 km/h, forexample, itis not twice butfour
times longer than30mph or50 km/h. Tiretrac-
tion isalso lesseffective whentheroads arewet
or slippery.

Brake
system function
Your Porsche isequipped withapower assisted
hydraulic dualcircuit brakesystem withdisc
brakes atthe front andrear.
Both circuits function independently. Onebrake
circuit operates thefront andtheother operates
the rear.
If one brake circuit hasfailed, theother willstill op-
erate. However, youwillnotice anincreased pedal
travel whenyouapply thebrakes.
Failure ofone brake circuit willcause thestopping
distance toincrease.
A
Warning!
Risk ofan accident.
In the unlikely eventofhydraulic failureof
one brake circuit:
t> Push thebrake pedaldownfirmly andhold itin
that position.
A mechanical linkageactivates thesecond cir-
cuit, andyou willbeable tobring thevehicle to
a stop.
t> After bringing yourvehicle toacomplete stop,
avoid driving thevehicle andinstead haveit
towed tothe nearest authorized Porschedeal-
er for repair.

To avoid overheating andpremature wearof
the brakes:
~ Before descending asteep grade, reduce

Brake
pads
Wear onthe brake padsandbrake discsdepends
to agreat extent onthe driving styleandthecon-
ditions ofuse and therefore cannotbeexpressed
in actual milesonthe road.
The high-performance brakesystem isdesigned
for optimal braking effectatall speeds andtem-
peratures.
Certain speeds, brakingforcesandambient
conditions (suchastemperature andhumidity)
therefore mightcause "brake noises".

New brake padsandbrake discshavetobe "bro-

Operation ofthe ABS system
A wheel speed sensor ismounted toeach ofthe
four wheels. Ifwheel lock-up ofeither ofthe front
wheels orthe rear wheels issensed duringbrak-
ing, thebrake pressure isadjusted automatically
until thewheel nolonger slips.Thebrake pressure
is regulated foreach frontwheel individually and
for both ofthe rear wheels together.
On aroad surface whichisslippery ononly one
side, therear wheel whichisbraking onthe slip-
pery surface determines thebrake pressure which
will beapplied equallytoboth rearwheels. Thisen-
sures thatdirectional stabilityismaintained. How-
ever, ifbraking forcesapproach thewheel lock-up
point forallwheels (panicbraking) theABS system
will intervene toprovide arapid rythmic braking.
The proper operation ofABS isperceived bythe
driver asapulsating brakepedalinconjunction
with audible noiseandperhaps somevibration.
I>
Ifyou experience thesesensations whiledriv-
ing oraroad surface withquestionable trac-
tion, reduce vehicle speedappropriate forthe
prevailing roadconditions.
The functional readinessofall the main electrical
components ofthe ABS ischecked byan
electronic monitoring systembothbefore and
while youdrive. •

If the ABS warning lampfailstogo out, thisindi-

ing, this indicates thatafault hasoccurred. Inboth
cases, normal braking, asinvehicles withoutABS,
is still retained.
The ABS system should,however, beexamined at
an authorized Porschedealerimmediately topre-
vent theoccurrence offurther faults.

Ifthe ABS system becomes inoperative, take
your vehicle toyour authorized Porschedealer
immediately.
A
Warning!
The control unitofthe ABS brake system is
set forstandard tiresize. Ifnon-standard
tires areinstalled, thecontrol unitmay mis-
interpret thespeed ofthe vehicle, because of
the variant dataitreceives fromthesensors
