Two car keys are supplied with your Porsche.
These keys operate all the locks on your vehicle.
f Be careful with your car keys: do not part with
them except under exceptional circumstances.
f To avoid battery run-down, always remove the
ignition key from the ignition lock. Emergency operationfPlease see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 74.
Replacement keys Replacement car keys can be obtained only from
your authorized Porsche dealer, and this can
sometimes be very time-consuming.
You should therefore always keep a spare key on
your person.
Keep it in a safe place (e.g. wallet), but under no
circumstances in or on the vehicle.
The key codes of new keys have to be “reported”
to the car control unit by your authorized Porsche
dealer.
A total of 6 car keys can be reported to the control
unit.
Disabling key codes
If a key is lost, the key codes can be disabled by
an authorized Porsche dealer.
All the remaining car keys are required for this pur-
pose.
Disabling the code ensures that the car can be
started only using authorized keys.
Note
f Please note that the other locks can still be
opened with the disabled key.
Immobilizer There is a transponder (an electronic component)
in the key grip, conta ining a stored code.
When the ignition is switch ed on, the ignition lock
checks the code.
The immobilizer can be deactivated and the en-
gine started only using an authorized ignition key.
Switching off the immobilizer
f Insert the ignition key into the ignition lock.
If the ignition is left on for more than 2 minutes
without the engine being started, the immobilizer
is switched on again.
f If this happens, turn the ignition key back to
position 3 (ignition off) before starting the
engine. The immobilizer is switched off again,
and the engine can be started.
f Please see the chapter “IGNITION/STARTER
SWITCH WITH ANTI-THEFT STEERING LOCK”

Operation, Safety
Seat adjustment for the passenger's seat Danger!
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body. Improperly positio-
ned safety belts can cause serious personal
injury or death in an accident.
f Do not operate the car with the driver or pas-
senger backrest excessively reclined.
f Porsche recommends the use of L.A.T.C.H.
(L ower Ancorage and Tether for Ch ildren)
equipped Porsche child seat.
Do not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be equipped with the LATCH system.
If the seat is in an extreme position (e.g., the back-
rest is in contact with the engine compartment
wall), the backrest can warp. Warping of the back-
rest can lead to malfunctions.
f Correct the seat adjustment.
Ensure that the seat is not jammed and is self-
supporting.
Ensure that the backrest is in the upright posi-
tion. f
Do not transport a load and objects behind and
under the passenger's seat.
If the load or objects ar e under the seat, it can
cause malfunctions.
If the weight on the passenger's seat is reduced
significantly, e.g., by supporting weight on the
armrest, the passenger's airbag can be switched
off.
f Select an upright seat position, and do not sup-
port weight on the armrests or lean out of the
window.
Always keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area. Do not lean against the inside of the door
or outside the window while the vehicle is mo-
ving.

Warning light and warning
message

Operation, Safety
Brake booster The brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not run-
ning, or if the brake boos ter is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
If this happens, ABS and PSM will also not oper-
ate.
Moisture or road salt on brakes affects braking.
Brakes will dry after a fe w cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Driving through water may reduce the trac-
tion.
Moisture on brakes from road water, car
wash, or coating of road salt may affect
braking efficiency.
f Cautiously apply brakes to test brakes after ex-posure to road water, etc.
Brake wear Your car has excellent brakes, but they are still
subject to wear. The rate at which they wear de-
pends on how the brakes are used.
f Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the "On" position and verifying that the warning
light illuminates.
If the warning lights in the instrument panel and on-
board computer stay on when the engine is run-
ning or come on while driv ing, the brake pads are
worn excessively.
f Do not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the con-
ditions of use and therefore cannot be expressed
in actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and tem-
peratures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause “brake noises”.
New brake pads or linings
New brake pads and brake discs have to be “bro-
ken in”, and therefore only attain optimal friction
when the car has covered several hundred miles
or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced.

Operation, Safety
When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes o
ut 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.
f If the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
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 th e vehicle, because of
the variant data it rece ives from the sensors
on the axles.
f Use only tire makes and types tested by Porsche.
Clutch Pedal The clutch pedal must be depressed fully
before the starter will engage.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
f Always check the movement of the clutch ped-
al before driving and make sure that it is not
obstructed by a floor mat or any other object.
f Secure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you
nonskid floor mats of the correct size.
To avoid damage to the clutch and transmis-
sion:
f Always depress the clutch pedal fully when
changing gears.
f Do not hold the car on a steep grade with the clutch pedal partially depressed.
Should the free travel of the clutch pedal suddenly
become larger, it could me an a malfunction of the
clutch.
f See your Porsche dealer for correction.
