AirbagSystems

The Airbags incombination withthesafety belts
makes upasafety system whichoffers thedriver
and thepassenger thegreatest knownprotection
from injuries incase ofaccident.
Even ifyour vehicle isequipped withairbags,
the
safety beltsmust beworn atall times,
be-

cause thefront airbag system isonly actuated by
frontal collisions withanimpact ofsufficient sever-
ity.
See shown figureforranges ofeffectiveness.
Controls, Instruments Below
theactuation threshold ofthe airbag sys-
tem, andduring typesofcollisions whichdonot
cause theactuation ofthe system, thesafety belts
provide theprimary protection tothe occupants
when correctly worn.

Therefore, allpersons withinthevehicle

der the door trimpanel.

Function

The front airbags aretriggered duringafrontal
collision ofsufficient force.
In the event ofaside impact ofcorresponding
force, theside airbag onthe impact sideistrig-
gered.
The inflation process generates theamount ofgas
required tofill the airbags atthe necessary pres-
sure infractions ofasecond.
Airbags protecttheface andupper body,whilst
simultaneously dampingthemotion ofthe driver
and passenger inthe impact direction inthe event
of afrontal impact orside impact.

The more thefuel level falls, themore spontane-
ously thedisplay reacts.Forthis reason, rangeon

Brake Fluidlevel

I>
Please observe thechapter "EXERCISE EX-
TREME CAUTION WHENWORKING ONYOUR
VEHICLE" onPage 112.

I>
Use only new(unused) OriginalPorsche
brake fluid.
A

Warning!
Brake fluidishazardous toyour health, and
may befatal ifswallowed.
Brake fluidalsoattacks paintwork.

I>
Keep brake fluidoutofchildren's reach.

I>
Take carewhile topping offbrake fluidnotto
soil theluggage compartment oritems oflug-
gage .
Checking thebrake fluidlevel
The reservoir forthe hydraulic brakingsystems is
in the luggage compartment.

I>
Check thebrake·fluid levelregularly atthe
transparent reservoir.
The fluid level should always liebetween the"MIN"
and "MAX" marks.
A slight decrease inthe fluid level duetowear and
automatic readjustment ofthe disc brakes isnor-

mal.
If, however, thefluid level fallsmarkedly orbelow
the "MIN" mark, thebraking systemmayhave
developed aleak.

I>
Have thebraking systemchecked immediately
at an authorized Porschedealer. Changing
thebrake fluid
Brake fluidabsorbs moisture fromtheairover
time. Thisaccumulation ofwater lowers theboil-
ing point and,under certain operating conditions,
can affect thebraking action.
Therefore havethebrake fluidchanged inaccor-
dance withthechange intervals statedinthe
brochure "Maintenance".

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.

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.

Tiredamage, puncture

t>
Check tiresforimbedded material,cuts,punc-
tures, cracks andbulges (sidewall)before
driving off.
In case oftire damage, whereitis uncertain
whether thereisabreak inthe plywith allits con-
sequences ortire damage causedbythermal or
mechanical overloading duetoloss ofpressure or
any other priordamage, werecommend thatthe
tire bereplaced forsafety reasons.
If one faulty tireisreplaced itshould benoted that
the difference intread depth onone axle must not
exceed 30
%.

Handling inconsistencies mayresult.

t>
Perform avisual inspection ifnecessary.
Tire replacements
If in doubt, contact yourPorsche dealeror
Porsche Importer ofyour country.
Use only tiremakes andtypes tested byPorsche.

If you donot use aPorsche recommended
replacement tire,make surethatyou
purchase yournewtires from areputable
tire dealer andthat thedealer complies with
all manufacturers warningsforthose tires.
Only tires withthesame make andwith the
same specification code(e.g."NO", "Nl"... )
can bemounted. Before
mounting newtires, check withyour
Porsche dealeraboutthecurrent release
status.
Use tires with"ZR" quality standards.
There
are currently nostandards concerning tire
strength atspeeds above150mph (240 kmjh).
Tires should bereplaced noless than onone axle
at the time.
Only tires ofthe same makeandtype must be
used. Mixed tiresarenotpermissible.
Initially, newtires donot have theirfulltraction.
You should therefore driveatmoderate speeds
during thefirst 60-120 miles (100-200 km).
If new tires areinstalled onlyonone axle, anotice-
able change inhandling occursduetothe different
tread depth ofthe other tires.
This happens especially ifonly reartires arere-
placed. However, thiscondition disappears asthe
new tires arebroken in.

t>
Please adjustyourdriving styleaccordingly.
Installation ofnew tires should onlybedone bya
qualified tiretechnician.
Valves

Rubber valvestems mustbereplaced everytime
a tire isreplaced.
For metal valves, theinstallation andreplacement
instructions mustbeobserved.
Use only genuine Porsche metalvalves.
Parking atthe curb

/!\
Warning!
Hard impacts againstcurbs(ortraffic
islands) aredangerous andmay cause hid-
den tiredamage whichisnot noticeable until
later. Suchdamage canresult inaccidents
at high speeds causing severepersonal inju-

ry.

Depending onthe force ofimpact, theedge
of the rim can also bedamaged.

t>
Ifyou areindoubt, havethewheel checked by
an expert, particularly ifyou suspect damage
on the inside.

I>
Ifyou must driveoveracurb orother obstacle,
drive slowly andatan obtuse angle.Exercise
