perfectly.
Interfering inthis system isonly anoption ifitcan

Coverings
~ Donot affix anycoverings (e.g.films or"stone

intakes. Damage duetoexcessive temperatures and
abrasion couldresult.

Motor racing

For reasons ofsafety, thebraking system, steer-
ing, running gear,wheels andtires ofyour car
should bechecked afterevery race.
On public highways, therunning gearandrear
spoiler mustbeinthe standard position.

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
the event ofan accident.

I>
Never allowanyone tosit inthe area behind the
seats.

Brakebooster

The brake booster assistsbraking onlywhen
the engine isrunning.

When thecar ismoving whiletheengine isnot run-
ning, orifthe brake booster isdefective, more
pressure onthe brake pedalisrequired tobring
the car toastop.
Moisture orroad saltonbrakes affects braking.
When thevehicle isdriven onsalted roadsforex-
tended periods, thebrakes shouldbewashed
down thoroughly aboutevery2weeks. Anauto-
matic carwash facilitycannot dothis jobproperly.
Brakes willdry after afew cautious brakeapplica-
tions.

/!\.
Warning!
Driving through watermayreduce thetrac-
tion. Moisture onbrakes fromroadwater, car
wash, orcoating ofroad saltmay affect
braking efficiency.

c>
Cautiously applybrakes totest brakes after
being exposed.
Brake
wear

Your carhas excellent brakes,butthey arestill
subject towear. Therate atwhich theywear de-
pends onhow thebrakes areused.

c>
Have thebrake system inspected atthe
intervals recommended inyour Maintenance
Booklet.

•• Warning lightUSA
• Warning lightCanada

If the warning lightsinthe instrument panelandon-
board computer stayonwhen theengine isrun-
ning orcome onwhile driving, thebrake padsare
worn, excessively.

c>
Donot continue tooperate thevehicle.
Have yourauthorized Porschedealerinspect
or replace thebrake pads.
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 padsorlinings

New brake padsandbrake discshavetobe "bro-
ken i",and therefore onlyattain optimal friction
when thecar has covered severalhundred miles

or km.

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