2004 PORSCHE 911 GT3 stop start

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.

The following tipswillbehelpful inobtaining opti-
mum performance fromyournewPorsche.
Despite themost modern, high-precision manufac-
turing methods, itcannot becompletely avoided
that themoving partshavetowear inwith each
other. Thiswearing-in occursmainlyinthe first
1,000 milesj1,600 km.

Therefore:
I>
Preferably takelonger trips.

I>
Avoid frequent coldstarts withshort-distance
driving whenever possible.

I>
Avoid fullthrottle startsandabrupt stops.

I>
Donot exceed maximum enginespeedof
4,200 rpm(revolutions perminute).

I>
Donot run acold engine athigh rpmeither in
Neutral oringear.

I>
Donot letthe engine labor,especially when
driving uphill.Shifttothe next lower gearin
time (usethemost favorable rpmrange).

I>
Never lugthe engine inhigh gear atlow
speeds. Thisruleapplies atall times, notjust
during thebreak-in period.

Donot participate inmotor racing events,
sports driving schools, etc.during thefirst
1,000 milesj1,600 kilometers.
There maybeaslight stiffness inthe steering,

period whichwillgradually disappear.

Break inbrake padsanddiscs

New brake padsanddiscs havetobe "broken in",
and therefore onlyattain optimal frictionwhenthe

The slightly reduced brakingabilitymustbecom-
pensated forbypressing thebrake pedalharder.
This alsoapplies whenever thebrake padsand

New tires

New tires donot have maximum traction.They
tend tobe slippery.

I>
Break innew tires bydriving atmoderate
speeds duringthefirst 60to120 milesj1 00to
200 km.Longer braking distances mustbean-
ticipated.
Engine

As always, therate ofoil consumption dependson
the quality andviscosity ofoil, the speed atwhich
the engine isoperated, theclimate androad con-
ditions, aswell asthe amount ofdilution andoxi-
dation ofthe lubricant.

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.
