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.

DearPorsche Owner

A lot has gone intothemanufacture ofyour
Porsche, includingadvanced engineering, rigid
quality control anddemanding inspections.
These engineering andsafety features willbe
enhanced byyou ...

the safe driver ...

- who knows hiscar and allcontrols,
- who maintains thevehicle properly,
- who uses driving skillswisely andalways
drives withinher/his owncapabilities andthe
level offamiliarity withthevehicle.
You willfind helpful hintsinthis manual onhow to
perform mostofthe checks listedonthe following
pages.
If in doubt, havethese checks performed byyour
authorized Porschedealer.

Before
driving off...

Check thefollowing itemsfirst

I>
Turn theengine offbefore youattempt any
checks orrepairs onthe vehicle.

I>
Besure thetires areinflated correctly.
Check tiresfordamage andtirewear.

I>
See that wheel boltsareproperly tightened
and notloose ormissing.

I>
Check engine oillevel, addifnecessary.
Make itahabit tohave engine oilchecked with
every fuelfilling.

I>
Check allfluid levels suchaswindshield
washer andbrake fluidlevels.

I>
Besure thevehicle battery iswell charged and
cranks theengine properly.

I>
Check alldoors andlidsforproper operation
and latch them properly.

I>
Check, andifnecessary replacewornor
cracked wiperblades.

I>
See that allwindows areclear andunob-
structed.

I>
Check airintake slotsandarea between lug-
gage compartment lidand windshield arefree
of snow andice,sothe heater andthewind-
shield wipers workproperly.
I>

Ifachild willberiding inthe vehicle, check
child seat/child seatrestraint systemtoen-
sure thatrestraints areproperly adjusted.

I>
Check allexterior andinterior lightsforopera-
tion andthat thelenses areclean.

I>
Check theheadlights forproper aim,andif
necessary, havethem adjusted.

I>
Check underthevehicle forleaks.

I>
Besure allluggage isstowed securely.

Emergency equipment

It is good practice tocarry emergency equipment
in your vehicle.
Some ofthe items youshould haveare:
window scraper, snowbrush, container orbag of
sand orsalt, emergency light,small shovel, first-
aid kit, etc.

Inthe driver's seat...

c>
Check operation ofthe horn.

c>
Position seatforeasy reach offoot pedals and
controls.
To reduce thepossibility ofinjury fromthe
airbag deployment, youshould always sitback
as far from thesteering wheelasispractical,
while stillmaintaining fullvehicle control.

c>
Adjustthe insideandoutside rearview mirrors.

c>
Buckle yoursafety belts.

C>
Check operation ofthe foot andparking brake.

C>
Check allwarning andindicator lightswith
ignition onand engine notrunning.

C>
Start engine andcheck allwarning displays for
warning symbols.

C>
Never leaveanidling carunattended.

C>
Lock doors frominside, especially withchil-
dren inthe cartoprevent inadvertent opening
of doors frominside oroutside.
Drive withdoors locked.
On
the road ...

C>
Never driveafteryouhave consumed alcohol
or drugs.

C>
Always haveyoursafety beltfastened.

C>
Always drivedefensively.
Expect theunexpected.

C>
Use signals toindicate turnsandlane changes.

C>
Turn onheadlights atdusk orwhen thedriving
conditions warrantit.

C>
Always keepasafe distance fromthevehicle
in front ofyou, depending ontraffic, roadand
weather conditions.

C>
Reduce speedatnight andduring inclement
weather. Driving inwet weather requirescautionandre-
duced speeds, particularly onroads with
standing water,asthe handling characteristics
of the vehicle maybeimpaired duetohydro-
planing ofthe tires.

C>
Always observe speedlimitsandobey road
signs andtraffic laws.

C>
When tired,getwell offthe road, stopandtake
a rest. Turntheengine off.Donot sitinthe ve-
hicle withengine idling.
Please observe thechapter "ENGINE EX-
HAUST" onPage 10.
C>

When parked, alwayssetthe parking brake.
Move thegearshift levertoreverse orfirst
gear.
On hills also turnthefront wheels towardthe
curb.

C>
When emergency repairsbecome necessary,
move thevehicle welloffthe road. Turnonthe
emergency flasheranduseother warning de-
vices toalert other motorists. Donot park or
operate thevehicle inareas where thehotex-
haust system maycome incontact withdry
grass, brush,fuelspill orother flammable ma-
terial.

C>
Make itahabit tohave theengine oilchecked
with every fuelfilling.

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.
