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.

Power transmission

The differential lock,which wasdesigned foruse
in motor sport,maymake aslight noisewhen
maneuvering andontight corners.

Porsche Ceramic Composite Brake
IPCCB)

The high-performance brakesystem isdesigned
for optimal braking effectatall speeds andtem-
peratures. Certainspeeds, brakingforcesandam-
bient conditions (suchastemperature andhumid-
ity) therefore mightcause brakenoises.
Wear onthe different components andbraking
system, suchasbrake padsorbrake discs,
depends toagreat extent onthe individual driving
style andtheconditions ofuse andtherefore
cannot beexpressed inactual milesonthe road.
The values communicated byPorsche arebased
on normal operation adaptedtotraffic. Wearin-
creases considerably whenthevehicle isdriven
on race tracks orthrough anaggressive driving
style.

I>
Please consult yourauthorized Porschedealer
about thecurrent guidelines
in
effect before
such useofyour vehicle.
Aerodynamic
components

To benefit fromthehigh driving performance with-
out impairing thedriving safetyorthe service life
of the vehicle components, certainvehicle parts
must bealways fullyoperational whiledriving.

I>
Regularly checkyourvehicle forsigns ofdam-
age.
Damaged, wornormissing aerodynamic com-
ponents suchasspoilers orunderside panels
affect driving behaviour andmust therefore be
replaced immediately.
To optimise thecooling ofthe PCCS brakediscs,
large airbrake spoilers arefitted tothe front and
rear running gearcontrol arms.
If these air-brake spoilersarenotfitted andthere
is ahigh thermal demand onthe braking system,
the service lifeofthe PCCS brakediscscould be
reduced.
The aerodynamic stabilityofthe vehicle isinflu-
enced considerably athigh speeds bythe front lip.
Due tothe small ground clearance requiredforthe
optimisation ofthe driving behaviour, thefront lip
and theair-brake spoilershavetobe placed inex-
posed positions tofulfil their function. Theycanbe
damaged, forexample byground orcurbstone
contact.
Ground
clearance

Please bear
in
mind thelimited ground clearance
of your caronuneven surfaces, whenparking
(curbs), onramps, liftingplatforms, etc.

Seating
Your carhas two seats.
The area behind theseats isnot intended forpas-
sengers.

A
Danger!
Severe personal injuryordeath canresult in
