Depending onuse, itcan bepossible ornecessary
to adapt thevehicle tothe respective conditions.
In the case, itmust always betaken intoaccount

Coverings
~ Donot affix anycoverings (e.g.films or"stone
guards") inthe area ofthe headlights andair
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

area ofyour vehicle atany time when fuel
fumes mightbepresent. Beespecially cau-
tious ofsuch devices suchashot water heat-
ers which igniteaflame intermittently.
~ Before working onany part inthe engine com-
partment, turntheengine offand letitcool
down sufficiently. Hotengine compartment
components canburn skinoncontact.
~ Bealert andcautious aroundengineatall
times whiletheengine isrunning.

Oil

Engine oilconsumption

It is normal foryour engine toconsume oil.
The rate ofoil consumption dependsonthe quality
and viscosity ofoil, the speed atwhich theengine
is operated, theclimate, roadconditions aswell
as the amount ofdilution andoxidation ofthe
lubricant.
If the vehicle isused forrepeated shorttrips, and
consumes anormal amount ofoil, the engine oil
measurement maynotshow anydrop inthe oil
level atall, even after600miles (1000 km)or
more. Thisisbecause theoilisgradually becom-
ing diluted withfuelormoisture, makingitappear
that theoillevel hasnotchanged.
The diluting ingredients evaporateoutwhen the
vehicle isdriven athigh speeds, ason anexpress-
way, making itthen appear thatoilisexcessively
consumed afterdriving athigh speeds.
If the conditions youdrive yourvehicle inare
dusty, humid, orhot, thefrequency ofthe oil
change intervals shouldbegreater. If
the vehicle isdriven atahigh rateofspeed,
climatic conditions arewarm, andtheload ishigh,
the oilshould bechecked morefrequently, as
driving conditions willdetermine therate ofoil
consumption.
- The engine inyour vehicle depends onoilto
lubricate andcool allofits moving parts.
Therefore, theengine oilshould bechecked
regularly andkept atthe required level.
- Make ita habit tohave theengine oillevel
checked withevery fuelfilling.
- The oilpressure warninglightisnot anoillevel
indicator.
The oilpressure warninglightindicates serious
engine damage maybeoccuring whenlit,ifen-
gine rpmisabove idlespeed.

Preconditions forcorrect
oillevel

measurement withtheoildipstick

Vehicle mustbelevel.
- Engine mustberunning andatoperating
temperature (engine coolant temperature ofatleast
176T /

80°C).
- The engine mustidleforatleast 20seconds
(under 1,000rpm).
- The airconditioning mustbeoff.

lint-free cloth.
3. Push dipstick fullyhome, withdraw againand
read offthe oillevel.
Push dipstick inas far asthe stop.
The

The difference betvv'eenthetwo marks isapproxi-
mately 1.0liter/l.l quarts.
4. Add engine oilquarter-liter atatime, ifneces-
sary.
5. Check oillevel withthedipstick again.
