ABS
(Anti-lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the driv-
er’s responsibility to adapt his driving style and
maneuvres in line with road and weather condi-
tions, as well as the traffic situation.
The increased safety that is provided should not in-
duce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with ABS.
Risks of accident due to inappropriate speed can-
not be reduced by ABS.
ABS ensures:
–Full steering control
The vehicle remains steerable
–Good driving stability
No skidding due to locked wheels
–Optimum braking distance
Shorter stopping distances in most cases
–Lock prevention
No flat spots on the tiresFunction
The decisive advantage of ABS is in the driving
stability and maneuvrability of the vehicle in
hazardous situations, even during heavy braking
while cornering.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until shortly
before the vehicle stops.
The ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable to
extremely rapid cadence braking.
The pulsating brake pedal and a “rattling noise”
warn the driver to adapt his driving speed to the
road conditions.Warning light
If the ABS warning lights light up in the instrument
panel and on the multi-purpose display of the in-
strument panel while the engine is running, the
ABS has switched off because of a fault.
In this event, the braking system will operate with-
out lock prevention,as in cars without ABS.
fAdapt your driving style to the changed brak-
ing behavior.
fThe ABS must be checked immediately at an
authorized Porsche dealer. This is necessary
in order to prevent the occurrence of further
faults whose effects cannot be defined.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with non-approved dimensions can
lead to different wheel speeds, causing the ABS to
switch off.

Changing the brake fluidBrake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating conditions,
can affect the braking action.
fTherefore, have the brake fluid changed in ac-
cordance with the change intervals stated in
the booklet “Guarantee and Maintenance”.
The warning light in the instrument panel and the
warning message on the multi-purpose display of
the instrument panel indicate
– indicate the brake level fluid is too low or,
– in conjunction with large pedal travel could in-
dicate a braking-circuit failure.
Note on operation
If the warning lights should light up while driving:
fStop immediately in a suitable place.
fDo not continue driving.
Please have the fault remedied at your nearest
authorized Porsche dealer.

Fuel
Warning!
Fuel is highly flammable and harmful to
health.
fFire, open flame and smoking are prohibited
when handling fuel.
fAvoid contact with skin or clothing.
fDo not inhale fuel vapours.
To prevent damage to the emission control
system and engine:
fNever drive the tank completely out of fuel.
fAvoid high cornering speeds after the warning lights have come on.To avoid permanent damage to the functionality of
the catalytic converters and oxygen sensors, use
only unleaded fuel.
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON is used.
If unleaded premium fuels with octane numbers of
at least 95 RON/85 MON are used, the en-
gine's knock control automatically adapts the igni-
tion timing.
The emission control system can be damaged in
various ways (e.g. fuelling incorrectly, shortage of
fuel, tow-starting).

Winter operationDuring the winter months, battery capacity tends
to decrease as temperatures drop. Additionally,
more power is consumed while starting, and the
headlights, heater, rear window defogger, etc.,
are used more frequently.
Let your Porsche dealer test the battery's capaci-
ty before winter sets in.Vehicle storageIf the car stands for long periods in the garage or
workshop, the doors and lids should be closed.
fRemove the ignition key and, if necessary, dis-
connect the battery.
Notes on operation
fWhen the battery is disconnected, the alarm
system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
fLock the vehicle and unlock it again.Maintenance note
Even if you put your vehicle out of operation, the
battery still discharges.
The battery will discharge more quickly if your ve-
hicle is not driven on a daily basis over a distance
of several miles. The more often you drive your ve-
hicle, and the longer the distance driven on each
trip, the more opportunity the vehicle‘s charging
system will have to recharge the batteries.
fTo preserve its efficiency, charge the battery
about every 6 weeks.
fCheck the battery acid level and top off with
distilled water if necessary.
fStore a battery that has been removed in a
dark, cool place, but not subject to freezing.
Putting vehicle into operationAfter the battery is connected or charged, the
PSM warning light lights up on the instrument pan-
el and a message appears on the multi-purpose
display of the instrument panel to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
To do this, turn the ignition key or the control
unit (on vehicles that have Porsche Entry &
Drive) to ignition lock position 2 twice.2. Perform a few steering movements and drive
a short distance in a straight line until the PSM
warning light goes out and the message is
erased from the memory of the multi-purpose
display of the instrument panel.
3. If the warnings does not go out, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied by an authorized
Porsche dealer.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
5. Perform adaptation of the power windows:
Please observe the chapter “STORING FINAL
POSITION OF THE DOOR WINDOWS” on
Page 35.
6. On vehicles with tire pressure monitoring:
Please observe the chapter “SYSTEM LEAR-
NING PHASE” on Page 104.
