Keep inmind thatthebraking distance increases
very rapidly asthe speed increases. At60 mph or
100 km/h, forexample, itis not twice butfour
times longer than30mph or50 km/h. Tiretrac-

Brake
system function

Your Porsche isequipped withapower assisted
hydraulic dualcircuit brakesystem withdisc
brakes atthe front andrear.
Both circuits function independently. Onebrake
circuit operates thefront andtheother operates
the rear.
If one brake circuit hasfailed, theother willstill op-
erate. However, youwillnotice anincreased pedal
travel whenyouapply thebrakes.
Failure ofone brake circuit willcause thestopping
distance toincrease.

A
Warning!
Risk ofan accident.
In the unlikely eventofhydraulic failureof
one brake circuit:

t> Push thebrake pedaldownfirmly andhold itin
that position.
A mechanical linkageactivates thesecond cir-
cuit, andyou willbeable tobring thevehicle to
a stop.
t> After bringing yourvehicle toacomplete stop,
avoid driving thevehicle andinstead haveit
towed tothe nearest authorized Porschedeal-
er for repair.

A

Warning!
To avoid overheating andpremature wearof
the brakes:

~ Before descending asteep grade, reduce
speed andshift thetransmission intoalower
gear ordriving position tocontrol speed.
~ Donot "ride thebrakes" byresting yourfooton
the pedal whennotintending toapply brake
pressure.
~ Donot hold thepedal downtoolong ortoo
often.
This could cause thebrakes toget hotand not
function properly.

Brakebooster

The brake booster assistsbraking onlywhen
the engine isrunning.

When thecar ismoving whiletheengine isnot run-
ning, orifthe brake booster isdefective, more

pads

Wear onthe brake padsandbrake discsdepends
to agreat extent onthe driving styleandthecon-
ditions ofuse and therefore cannotbeexpressed
in actual milesonthe road.
The high-performance brakesystem isdesigned
for optimal braking effectatall speeds andtem-
peratures.
Certain speeds, brakingforcesandambient
conditions (suchastemperature andhumidity)
therefore mightcause "brake noises".

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.
