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
the event ofan accident.

I>
Never allowanyone tosit inthe area behind the
seats.

Break inhints forthe first
1,000 miles/l,600 kilometers
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.
Controls, Instruments
I>

Donot participate inmotor racing events,
sports driving schools, etc.during thefirst
1,000 milesj1,600 kilometers.
There maybeaslight stiffness inthe steering,
gear-shifting orother controls duringthebreak-in
period whichwillgradually disappear.

Break inbrake padsanddiscs

New brake padsanddiscs havetobe "broken in",
and therefore onlyattain optimal frictionwhenthe
car has covered severalhundred milesorkm.
The slightly reduced brakingabilitymustbecom-
pensated forbypressing thebrake pedalharder.
This alsoapplies whenever thebrake padsand
brake discsarereplaced.

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
oilconsumption

During thebreak-in periodoilconsumption maybe
higher thannormal.
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.

I>
Make ahabit ofchecking engineoilwith every
fuel filling, addifnecessary.

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.
