The keycodes ofnew keys have tobe "reported"
to the carcontrol unitbyyour authorized Porsche
dealer.
The keygrip ofthe spare keycan beexchanged
for amain-key grip.

Disabling keycodes

If a key islost, thekey codes canbedisabled by
an authorized Porschedealer.
All the remaining carkeys arerequired forthis pur-
pose.
Disabling thecode ensures thatthecar can be

started
onlyusing authorized keys.

Immobilizer

There isatransponder (anelectronic component)
in the key grip, containing astored code.
When theignition isswitched on,the ignition lock
checks thecode.
The immobilizer canbedeactivated andtheen-

Note

If the ignition isleft onfor more thantwominutes
without starting theengine, theimmobilizer isre-
activated.

Brakebooster

The brake booster assistsbraking onlywhen
the engine isrunning.

When thecar ismoving whiletheengine isnot run-
ning, orifthe brake booster isdefective, more
pressure onthe brake pedalisrequired tobring
the car toastop.
Moisture orroad saltonbrakes affects braking.
When thevehicle isdriven onsalted roadsforex-
tended periods, thebrakes shouldbewashed
down thoroughly aboutevery2weeks. Anauto-
matic carwash facilitycannot dothis jobproperly.
Brakes willdry after afew cautious brakeapplica-
tions.

/!\.
Warning!
Driving through watermayreduce thetrac-
tion. Moisture onbrakes fromroadwater, car
wash, orcoating ofroad saltmay affect
braking efficiency.

Cautiously applybrakes totest brakes after
being exposed.

Brake
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".

New brake padsorlinings

New brake padsandbrake discshavetobe "bro-
ken i",and therefore onlyattain optimal friction
when thecar has covered severalhundred miles

or km.

The slightly reduced brakingabilitymustbecom-
pensated forbypressing thebrake pedalharder.
This alsoapplies whenever thebrake padsand

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-

cases, normal braking, asinvehicles withoutABS,
is still retained.
The ABS system should,however, beexamined at
an authorized Porschedealerimmediately topre-
vent theoccurrence offurther faults.

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