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.

Storing yourPorsche

If you intend tostore yourPorsche foraprolonged
period, pleaseconsult yourauthorized Porsche
dealer. Thestaff willbeglad toadvise youonthe
most suitable andnecessary methods.
r> Clean yourvehicle thoroughly insideandout-
side.
Clean theengine compartment.
The under carriage andchassis components
should befree ofdirt and saltdeposits.
r> Fillupthe fuel tank.
r> Change theoiland oilfilter, andrunthe engine
for several minutes.
r>

Increase thetire pressure to58 psi (4bar).
It is not recommended tolift the vehicle, dueto
the possibility ofcorrosion onshock absorber
piston shafts.
The vehicle shouldbemoved slightly, approxi-
mately everyfourweeks, toprevent flatspot
on the tires.

Climate control

The airconditioning systemshouldbeingood
working condition andfully charged.

WindshieldjHeadlight washer

r> Check andcorrect antifreeze/cleaning solu-
tion level asnecessary.

Electrical system

r> Remove thebattery fromthevehicle andstore
it in acool dryplace, notonacement floor.

When thebattery isdisconnected, the
alarm system isdeactivated.

r> Recharge thebattery every3months. Ifthe
battery remains inthe vehicle withthecables
connected, itis necessary tocheck, remove
and recharge thebattery every2-3weeks.

Do not fast charge thebattery.

r> Please observe thechapter "SATTERY" on

Unifonn TireQuality Grading

Quality grades canbefound where applicable on
the tire sidewall between treadshoulder andmax-
imum section width.

PracticalTips,Emergency Service
Example

All passenger cartires must conform toFederal
Safety Requirements inaddition tothese grades.
Treadwear

The treadwear gradeisacomparative rating
based onthe wear rateofthe tire when tested un-
der controlled conditions onaspecific govern-
ment testcourse.
For example, atire graded 150would wearone
and ahalf (1-1/2) timesaswell onthe government
course asatire graded 100.
The relative performance oftires depends upon
the actual conditions oftheir use,however, and
may depart significantly fromthenorm duetovari-
ations indriving habits, service practices anddif-
ferences inroad characteristics andclimate.

Traction AA,A,B,C

The traction grades,fromhighest tolowest, are
AA, A,S,and Cand they represent thetire's ability
to stop onwet pavement asmeasured undercon-
trolled conditions onspecified government test
surfaces ofasphalt andconcrete.
A tire marked Cmay have poortraction perfor-
mance.

A
Warning!

The traction gradeassigned tothis isbased on
braking (straight-ahead) tractiontestsanddoes
not include cornering (turned)traction, accelera-
tion, hydroplaning orpeak traction characteris-
tics.
