Operation of the ABS systemA wheel speed sensor is mounted to each of the
four wheels. If wheel lock-up of either of the front
wheels or the rear wheels is sensed during brak-
ing, the brake pressure is adjusted automatically
until the wheel no longer slips. The brake pressure
is regulated for each front wheel individually and
for both of the rear wheels together.
On a road surface which is slippery on only one
side, the rear wheel which is braking on the slip-
pery surface determines the brake pressure which
will be applied equally to both rear wheels. This en-
sures that directional stability is maintained. How-
ever, if braking forces approach the wheel lock-up
point for all wheels (panic braking) the ABS system
will intervene to provide a rapid rythmic braking.
The proper operation of ABS is perceived by the
driver as a pulsating brake pedal in conjunction
with audible noise and perhaps some vibration.
fIf you experience these sensations while driv-
ing or a road surface with questionable trac-
tion, reduce vehicle speed appropriate for the
prevailing road conditions.
The functional readiness of all the main electrical
components of the ABS is checked by an
electronic monitoring system both before and
while you drive. When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes out when the engine is
started if the check is not yet complete.
If the ABS warning lamp fails to go out, this indi-
cates that ABS has been deactivated due to a
fault. If the warning lights in the instrument panel
and on-board computer light up while you are driv-
ing, this indicates that a fault has occurred. In both
cases, normal braking, as in vehicles without ABS,
is still retained.
The ABS system should, however, be examined at
an authorized Porsche dealer immediately to pre-
vent the occurrence of further faults.
fIf the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
The control unit of the ABS brake system is
set for standard tire size. If non-standard
tires are installed, the control unit may mis-
interpret the speed of the vehicle, because of
the variant data it receives from the sensors
on the axles.
fUse only tire makes and types tested by Porsche.

Warning!
Serious injury may result if you are involved
in a collision without having fastened the
safety belts.
fFasten safety belts before driving away. Before starting the engine fApply the footbrake.
fManual transmission:
Move the gearshift lever into neutral.
The clutch pedal must be depressed fully

fTiptronic:
Move the selector lever to P or N.
Temperature sensors on the engine automatically
provide the correct fuel/air mixture required for
starting.
Therefore, it is not necessary to depress the
accelerator pedal while starting a cold or a
warm engine.
Starting the enginefTurn ignition key to ignition lock position 2.
fAs soon as the engine starts, release the igni-
tion key.
The first operation of the starter is ended automat-
ically when the engine starts.
If the engine does not start, subsequent starter
operations will not be ended automatically.
If the engine fails to start after 10 or 15 seconds
of cranking:
fWait about 10 seconds before engaging the
starter again.
fWhen starting the engine, be ready to drive
immediately.
Drive vehicle at moderate speeds and avoid
engine speeds above 4,200 rpm during the
first 5 minutes.
fDo not let the engine idle to warm up.
Danger!
Engine exhaust fumes have many compo-
nents which you can smell. They also contain
carbon monoxide (CO), which is a colorless
and odorless gas.
Carbon monoxide can cause unconscious-
ness and even death if inhaled.
fNever start or let the engine run in an en-
closed, unventilated area.
It is not recommended to sit in your car for pro-
longed periods with the engine on and the car
not moving.
An unattended vehicle with a running engine
is potentially hazardous.
If warning lights should come on to indicate
improper operation, they would go unno-
ticed.
fNever leave the engine idling unattended.
Danger of fire.
fDo not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or oth-
er flammable material.
fIf your car catches on fire for any reason, call
the fire department.
Do not endanger your life by attempting to put out the fire.

Stopping Engine fTurn key back to position 3.
fDo not stop engine immediately after hard or
extended driving.
Keep engine running at increased idle for
about two minutes to prevent excessive heat
build-up before turning off engine.
fTo avoid battery run-down, always remove the
ignition key from the ignition lock.
fMake sure that when you leave the car, even
briefly, you have withdrawn the ignition key.
fEngage the steering lock by moving the steer-
ing wheel to the left or right.
Turn the steering wheel to the locking position
before you switch off the engine so that you
don’t have to exert yourself when locking or
unlocking the steering.
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool down sufficiently.
Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment blower is mounted on
the engine compartment lid.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
fCarry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution.
Risk of injury. The radiator fans in the front
end of the car may be operating or
unexpectedly start operating when the
engine is switched on.
fCarry out work in these areas only with the en-gine switched off.
Automatic garage door The ignition system in your Porsche may interfere
with your electronically operated garage door.
fTo check this, drive your Porsche close to the
garage door. Make sure not to interfere with
the operating range of the door.
fRun the engine at different speeds.
If the garage door opens or closes without you op-
erating the garage door unit in your car, contact
the dealer who installed the automatic garage
door to have the frequency and/or coding of the
garage door signal changed or modified.
