Inthe loaded state,adjust maximum speedto
the nature, sizeandweight ofthe load being
carried.
In no case, however, shouldyoudrive atmore
than 90mph (140 km/h).

c>
With thebasic carrier installed andnoload, do
not exceed amaximum speedof110 mph
(180 km/h) sincedriving stability willbead-
versely affected.
Adapt yourdriving styleandspeed tothe
changed conditions.
Nevertheless, Porscherecommends thatyou
do not exceed theposted speedlimit.

c>
Driving, brakingandsteering behavior ofthe
vehicle change duetothe higher center of
gravity andthegreater wind-resistant area.
You should adaptyourdriving styleappropri-
ately.

Note

Since fuelconsumption andnoise areincreased
with theRoof Transport Systeminstalled, itshould
not remain onthe car ifit is not inuse.

FuelEconomy

Fuel economy willvary depending onwhere,
when andhow youdrive, optional equipment
installed, andthegeneral condition ofyour
car.
A car tuned tospecifications andcorrectly
maintained, willhelp youtoachieve optimal
fuel economy.

~ Have yourvehicle tunedtospecifications.
Air cleaner shouldbedirt free toallow proper
engine "breathing".

Wheels shouldbeproperly aligned.
Tires should beinflated atcorrect pressure.
~ Always monitor yourfuelconsumption.
~ Drive smoothly, avoidabrupt changes inspeed
as much aspossible.
~ Avoid jackrabbit startsandsudden stops.
~ Donot drive longer thannecessary inthe lower
gears. Shifting intoahigher gearearly without
lugging theengine willhelp save fuel.
~ Prolonged "warmup"idling wastes gas.Start
the vehicle justbefore youareready todrive.
Accelerate slowlyandsmoothly.
~ Switch offthe engine ifstationary forlonger
periods.
Maintenance, CarCare ~
Any additional weightcarried inthe vehicle re-
duces fueleconomy. Alwayskeepcargo toa
minimum andremove allunnecessary items.
~ Organize yourtripstotake inseveral errands
in one trip.
~ Allelectrical accessories contributetoin-
creased fuelconsumption.
~ Only switch onthe airconditioning whenneces-
sary.
~ Donot drive withtheRoof Transport System
mounted unlessyouneed it.

The EPA estimated m.p.g.isto be used for
comparison purposes,actualmileage may
be different fromtheestimated m.p.g.,
depending onyour driving speed,weather
conditions andtriplength. Youractual
highway mileagewillprobably beless than
the estimated m.p.g.

~ Please observe alllocal andnational speed
limits.
Operating
YourPorsche inother
Countries

Government regulationsinthe United States and

nentallimits ofthe United States orCanada, there
is the possibility that
- unleaded fuelmay notbeavailable;
- unleaded fuelmay have aconsiderably lower
octane rating.Excessive engineknockandse-
rious damage toboth engine andcatalytic con-
verters couldresult;
- service maybeinadequate duetolack ofprop-
er service facilities, toolsordiagnostic equip-
ment;
- replacement partsmaynotbeavailable orvery
difficult toget.

Porsche cannotberesponsible forthe
mechanical damagethatcould result
because ofinadequate fuel,service orparts
availability.

If you purchased yourPorsche abroadandwant to
bring itback home, besure tofind outabout ship-
ping andforwarding requirements, aswell ascur-
rent import andcustoms regulations.

Washing

The best method ofprotecting yourcarfrom the
damaging effectsofthe environment isfrequent
washing andtheapplication ofapreservative. The
underside ofyour vehicle shouldalsobewashed
thoroughly, atthe latest whensaltisno longer
spread onthe roads.
The longer salt,road dustandindustrial dust,
dead insects, birddroppings orsubstances from
trees (resin, pollen) areallowed toremain onthe
bodywork, themore serious istheir harmful ef-
fect.
New cars should bewashed carefully withplenty
of clear water toprotect thenew paint work. Dark
paint finishes showupthe smallest ofsurface
damage (e.g.,scratches) morereadily thanlighter
colors.
Dark colors arealso more susceptible toscratch-
ing because ofthe composition oftheir pigments
and require particularly carefulpaintcare.

D-
Donot wash yourcarinbright sunlight orwhile
the bodywork isstill hot.

D-
When washing byhand, useabundant water,a
soft sponge orwash brush, andPorsche car
shampoo.

D-
Begin byspraying thebody thoroughly withwa-
ter torinse away loose dirt.
D-

After washing, rinsethecarwith plenty ofwa-
ter and then drywith achamois leather.
Do not use thesame chamois leatherfordry-
ing asyou useforcleaning thewindshield and
windows.

/!\
Warning!
Moisture whichgetsontothe brakes during
a car wash canreduce braking efficiency or
make thebrakes pullunevenly whichcould
increase thedanger ofan accident, causing
serious personal injuriesordeath.

D-
Always applythebrakes afew times after
washing thecartotest braking efficiency and
dry the brake discs.
When doingthis,take care nottohamper other
road users behind you(traffic conditions per-
mitting),

Automatic carwashes

Optional add-onpartsorparts which project
beyond thecontours ofthe vehicle maybe
damaged bydesign features (e.g.brushes) ofau-
tomatic carwashes.
The
following partsareparticularly
susceptible todamage:

- Windshield wipers(always switchthemoffto
prevent themwiping unintentionally inintermit-
tent operation)
- External telephone antennas(alwaysunscrew)
- Roof Transport System(alwaysremove com-
pletely)
- Rear spoiler
- Wheels (thewider therimand thelower thetire
height, thegreater therisk ofdamage)
- High-gloss wheels(toprevent thesefromget-
ting scratched, donot clean withthewheel-
cleaning brushesofthe carwash).

D-
Please consult theoperator beforeusingauto-
matic carwashes.

D-
Wash anddrybyhand allpoints notreached by
a car wash, suchasdoor andlidseams or
door sills.

Maintenance, CarCare

Doorlocks

t>
Toprevent thedoor locks fromfreezing during
the cold season, thelock cylinders shouldbe
covered duringawash.

t>
Should thelocks freeze, useanordinary de-
icer. Inmany cases, awell warmed keycan
help. Never useexcessive force.

Paint

t>
Never rubadusty carwith adry cloth since
dust particles areabrasive andcould dulland
damage thesurface finish.
The paintwork ofyour carisexposed toall types
of mechanical andchemical conditions, particular-
ly climatic onessuchasbright sunlight, rain,frost
and snow. Ultraviolet light,rapid changes intem-
perature, rain,snow, industrial dustandchemical
deposits constantly attackthepaint which isonly
able towithstand suchexposure inthe long term

if
itis given regular careandattention.

t>
Donot apply silicone polishes tothe windshield
or windows.

t>
Donot treat matt-painted componentswith
preservatives orpolishes asthis willspoil the
matte effect.

132
Maintenance, CarCare Preservation
The paint surface becomes dullover timedueto
weathering. Itis therefore necessary topreserve
the paint regularly.
This keeps thepaint shiny andelastic. Dirtispre-
vented fromadhering tothe paint surface andin-
dustrial dustisprevented frompenetrating the
paint.
Provided itis washed andtreated withpreserva-
tive regularly, thebrand newfinish ofyour carwill
be retained foryears tocome.

t>
Apply thePorsche paintpreservative afterthe
car wash andpolish itdry toobtain abright fin-
ish orsimply addaliquid preservative regularly
to the final rinse water.
Polishing Do not resort tousing Porsche polishuntilitbe-
comes evident thatthenormal preservatives no
longer produce thedesired finish.
Spots andstains

t>
Remove tarstains, grease, oilspots anddead
insects assoon aspossible withInsect Remov-
er. They cancause discoloration ifallowed to
remain onthe paintwork.

t>
Wash theaffected areaimmediately aftertreat-
ing it. Minor
paintdamage

t>
Have minor paintdamage, suchasscratches,
scores orchips caused byflying stones, re-
paired immediately byyour authorized
Porsche dealerbefore corrosion setsin.
However, ifthere arealready tracesofcorrosion,
they must firstberemoved carefullyandthorough-
ly. Coat thearea witharust-proofing primerand
finish offwith atop coat. Thepaint code andcolor
number arefound onthe vehicle's paintdataplate.

Engine compartment

The engine compartment andthesurface ofthe
engine aretreated withacorrosion-inhibitor atthe
factory.
If degreasing solventsareused toclean theen-
gine compartment orthe engine iswashed down,
the process almostinvariably removesthecorro-
sion-inhibiting coating.Itis then absolutely neces-
sary tohave adurable preservative appliedtoall
surfaces, bodyseams, jointsandassemblies in
the engine compartment. Thisalsoapplies when
corrosion-inhibitor partsarereplaced.

/!\
Caution!

Risk ofdamage tothe generator.

c>
Donot point thecleaning jetdirectly atthe al-
ternator, orcover thealternator.
Effective corrosion-proofing isparticularly impor-
tant during thecold weather season.Ifyour caris
driven frequently inareas where salthasbeen
spread onthe roads, thewhole engine compart-
ment should becleaned thoroughly afterthewin-
ter toprevent saltfrom causing anylasting dam-
age. Afull under-body washshould alsobeper-
formed atthe same time.
Windows

The road dustwhich settles onthe windshield and
windows containsparticles oftire rubber andoil
residue. Theinterior trimandupholstery release
particles, particularly instrong sunlight, whichcol-
lect onthe insides ofthe windows. Thesedeposits
are augmented byimpurities inthe airwhich en-
ters thecarthrough thefresh airvents.

c>
Clean allwindows regularly, insideandoutside,
with Porsche windowcleaner.

c>
Ifyou useachamois leatherforthe windows,
do not use itfor paintwork asitwill otherwise
pick upacertain amount ofpreservative orpol-
ish and could smear tilewindows andthus im-
pair vision.

c>
Remove deadinsects withthePorsche insect
remover.

Wiper blades

Wiper blades thatareinperfekt condition arevital
for aclear view.

c>
Replace thewiper blades twiceperyear (be-
fore andafter thecold season) orwhenever
wiper performance deteriorates.
C>

Periodically cleanthewiper blades with
Porsche windowcleaner, especially afterthe
vehicle hasbeen washed inacar wash.
If they arevery dirty (e.g. withinsect remains),
they canbecleaned withasponge orcloth.

Undercoating

As itis not possible toexclude therisk ofdamage
to this protective coatinginday today driving, it
is advisable tohave theunderside ofthe car in-
spected atcertain intervals -preferably beforethe
start ofwinter andagain inspring -and theunder-
coating restored asnecessary.
Your authorized Porschedealerisfamiliar withthe
bodyseal treatment procedures andhasthenec-
essary equipment forapplying factoryapproved
materials. Werecommend thatyouentrust them
with such work andinspections.
Unlike conventional sprayoils,undercoating and
rust-proofing compoundsbasedonbitumen or
