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
must always wearsafety belts
(inmany states,
state lawrequires theuse ofsafety belts).

I>
Please observe thechapter "SAFETY BELTS"
on Page 32.
The front airbags arelocated behindthepadded
steering wheelpanelonthe driver's sideandon
the passenger's sideinthe dashboard.
The side airbags (POSIP-Porsche SideImpact
Protection System)areinstalled inthe doors un-
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.
A

Danger!
To provide optimal occupant protection, air-
bags must inflate atvery highspeed.
If you arenotwearing yoursafety beltorare
too close tothe airbag whenitsdeployed, in-
flating airbags canresult inserious injuryor
death.

I>
Make surethere arenopeople, animals orob-
jects between thedriver orpassenger andthe
area intowhich theairbag inflates.

I>
Sitback asfar from thedashboard orsteering
wheel asispractical, whilestillmaintaining full
vehicle control.

I>
Donot lean against theinside ofthe doors.

I>
Always holdthesteering wheelbythe outer
rim. Never restyour hands onthe airbag panel.

I>
Never transport heavyobjects onorinfront of
the passenger seat.

I>
Always keepthelidofthe door storage com-
partment closed.Objects mustnotprotrude
out ofthe door storage compartment.

Give your passenger allofthe information in
this chapter.

Nochanges mustbemade tothe wiring or
components ofthe airbag system.

ABSBrake System
(Antilock BrakeSystem)

The ABS system represents amajor contribution
to the enhancement ofactive safety inyour vehi-
cle. This system prevents thewheels fromlocking
in apanic stoponalmost allroad surfaces.
Controls, Instruments
With
theASS system inyour vehicle, the
following areasareenhanced:
Steering,
vehicleremains steerable underall
braking forceswhenABSisengaged.

Good directional control,
noswerving caused
by locking ofwheels underbraking conditions.

Shorter stopping distance,
stoppingdistances
are usually reduced because controlled brakingis
maximized.

Prevention of
wheel lock
up,
nobrake- induced
sliding andthus nolocalized tirewear fromemer-
gency braking.
The crucial advantage ofthe ABS system overa
conventional brakesystem isinthe area ofmain-
taining directional controlandmaneuverability of
the car inemergency situationsduringnormal
driving, including panicbraking inturns.
A

Warning!
The increased controlthatisprovided should
not induce youtotake greater riskswithyour
safety. Thelimits dictated bythe laws of
physics cannotbeovercome, evenwithASS.
The riskofaccidents duetoinappropriate
speed cannot bereduced, evenbythe ASS.
The driver bearstheresponsibility forall
driving maneuvers.

t>
Adapt yourdriving styletothe prevailing road
and weather conditions.
t> Obey alltraffic laws.

Other vehicles notequipped withtheASS
system maynotbeable tomaintain control,
especially onwet orpoor roadsurfaces and
thus maybemore likelytoimpact youfrom
behind.

t>
Tominimize thatrisk, useyour ABSsystem to
increase yourability tomaneuver toavoid dan-
gerous situations andnotmerely totry tostop
in the shortest distance possible.

Operation ofthe ABS system
A wheel speed sensor ismounted toeach ofthe
four wheels. Ifwheel lock-up ofeither ofthe front
wheels orthe rear wheels issensed duringbrak-
ing, thebrake pressure isadjusted automatically
until thewheel nolonger slips.Thebrake pressure
is regulated foreach frontwheel individually and
for both ofthe rear wheels together.
On aroad surface whichisslippery ononly one
side, therear wheel whichisbraking onthe slip-
pery surface determines thebrake pressure which
will beapplied equallytoboth rearwheels. Thisen-
sures thatdirectional stabilityismaintained. How-
ever, ifbraking forcesapproach thewheel lock-up
point forallwheels (panicbraking) theABS system
will intervene toprovide arapid rythmic braking.
The proper operation ofABS isperceived bythe
driver asapulsating brakepedalinconjunction
with audible noiseandperhaps somevibration.

I>
Ifyou experience thesesensations whiledriv-
ing oraroad surface withquestionable trac-
tion, reduce vehicle speedappropriate forthe
prevailing roadconditions.
The functional readinessofall the main electrical
components ofthe ABS ischecked byan
electronic monitoring systembothbefore and
while youdrive. •

If the ABS warning lampfailstogo out, thisindi-

fault. Ifthe warning lightsinthe instrument panel
and on-board computer lightupwhile youaredriv-
ing, this indicates thatafault hasoccurred. Inboth
cases, normal braking, asinvehicles withoutABS,
is still retained.
The ABS system should,however, beexamined at
an authorized Porschedealerimmediately topre-
vent theoccurrence offurther faults.

I>
Ifthe ABS system becomes inoperative, take
your vehicle toyour authorized Porschedealer
immediately.

Warning!
The control unitofthe ABS brake system is
set forstandard tiresize. Ifnon-standard
tires areinstalled, thecontrol unitmay mis-
interpret thespeed ofthe vehicle, because of
the variant dataitreceives fromthesensors
on the axles.

I>
Use only tiremakes andtypes tested by
