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.

Environmentally friendlyvehicles

Modern environmental technologyensurescom-
pliance withallemission lawsapplicable world-
wide.

These havethefollowing advantages:

- Rapid operational readinessofthe catalytic
converters ensureslowemissions, evenin
short-trip operation.
- Reliable operation andgood emission control

Recycling
-for aPorsche, thisisvirtually
an academic question

More thantwo-thirds ofall Porsches everbuiltare
still running.

Just incase recycling isever necessary, we
take thefollowing precautionary measures:

- Identification ofall materials.
- Use ofrecyclable materials.
- Reusable components designedforsimple
removal.
- These reasons resultinafurther increase in
the recycling ratewhich iscurrently 80per
cent.

gine performance andenvironmental compati-
bility.

AirbagSystems

The Airbags incombination withthesafety belts
makes upasafety system whichoffers thedriver
and thepassenger thegreatest knownprotection
from injuries incase ofaccident.
Even ifyour vehicle isequipped withairbags,
the
safety beltsmust beworn atall times,
be-

cause thefront airbag system isonly actuated by
frontal collisions withanimpact ofsufficient sever-
ity.
See shown figureforranges ofeffectiveness.
Controls, Instruments Below
theactuation threshold ofthe airbag sys-
tem, andduring typesofcollisions whichdonot
cause theactuation ofthe system, thesafety belts
provide theprimary protection tothe occupants
when correctly worn.

Therefore, allpersons withinthevehicle
must always wearsafety belts
(inmany states,
state lawrequires theuse ofsafety belts).

I>
Please observe thechapter "SAFETY BELTS"
on Page 32.
The front airbags arelocated behindthepadded
steering wheelpanelonthe driver's sideandon
the passenger's sideinthe dashboard.
The side airbags (POSIP-Porsche SideImpact
Protection System)areinstalled inthe doors un-
der the door trimpanel.

Function

The front airbags aretriggered duringafrontal
collision ofsufficient force.
In the event ofaside impact ofcorresponding
force, theside airbag onthe impact sideistrig-
gered.
The inflation process generates theamount ofgas
required tofill the airbags atthe necessary pres-
sure infractions ofasecond.
Airbags protecttheface andupper body,whilst
simultaneously dampingthemotion ofthe driver
and passenger inthe impact direction inthe event
of afrontal impact orside impact.
A

Danger!
To provide optimal occupant protection, air-
bags must inflate atvery highspeed.
If you arenotwearing yoursafety beltorare
too close tothe airbag whenitsdeployed, in-
flating airbags canresult inserious injuryor
death.

I>
Make surethere arenopeople, animals orob-
jects between thedriver orpassenger andthe
area intowhich theairbag inflates.

I>
Sitback asfar from thedashboard orsteering
wheel asispractical, whilestillmaintaining full
vehicle control.

I>
Donot lean against theinside ofthe doors.

I>
Always holdthesteering wheelbythe outer
rim. Never restyour hands onthe airbag panel.

I>
Never transport heavyobjects onorinfront of
the passenger seat.

I>
Always keepthelidofthe door storage com-
partment closed.Objects mustnotprotrude
out ofthe door storage compartment.

I>
Give your passenger allofthe information in
this chapter.

I>
Nochanges mustbemade tothe wiring or
components ofthe airbag system.

~Donot add anyadditional coverings orstickers
to the steering wheelorinthe area ofthe pas-
senger airbagandside airbags. Doingsomay
adversely affectthefunctioning ofthe airbag
system orcause harmtothe occupants ifthe
airbag system shoulddeploy.
~ Donot undertake anywiring forelectrical ac-
cessory equipment inthe vicinity ofthe airbag
wiring harnesses. Doingsomay disable the
airbag system orcause inflation.
~ Ifthe warning lightcomes on,the airbag sys-
tem should berepaired immediately byyour
authorized Porschedealer.

Note

Airbag components (e.g.steering wheel,door
trim) maybedisassembled onlybyanauthorized
Porsche dealer.
When disposing ofaused airbag unit,oursafety
instructions mustbefollowed. Theseinstructions
can beobtained atany authorized Porschedealer.
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
the vehicle isequipped withairbags, andrefer
them tothe chapter, "AirbagSystems", inthe own-
er's manual (safetyanddisposal rules).

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.
