Dear Porsche Owner A lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections.
These engineering and safety features will be
enhanced by you... the safe driver... – who knows his car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely, and always
drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages.
If in doubt, have these checks performed by your
authorized Porsche dealer.
Before driving off... Check the following items first fTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every fuel filling.
fCheck all fluid levels such as windshield was-
her and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck and if necessary replace worn or cra-
cked wiper blades.
fSee that all windows are clear and unobstruc-
ted.
fCheck air intake slots and area between front
lid and windshield are free of snow and ice, so
the heater and the windshield wipers work pro-
perly. fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if ne-
cessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe sure all luggage is stowed securely.
Emergency equipment It is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are:
window scraper, snow brush, container or bag of
sand or salt, emergency light, small shovel, first-
aid kit, etc.

Keys fPlease observe the chapter “CENTRAL LO-
CKING IN CARS WITH ALARM SYSTEM” on
Page 21.
Two main keys and one spare key are supplied
with your Porsche.
These keys operate all the locks on your vehicle.
fBe careful with your car keys: do not part with
them except under exceptional circumstances.
fTo avoid battery run-down, always remove the
ignition key from the ignition lock.
Replacement keys Replacement car keys can be obtained only from
your authorized Porsche dealer, and this can so-
metimes be very time-consuming.
You should therefore always keep the 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.
The key grip of the spare key can be exchanged
for a main-key grip.
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
fPlease 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, containing a stored code.
When the ignition is switched on, the ignition lock
checks the code.
The immobilizer can be deactivated and the engi-
ne started only using an authorized ignition key.
Switching off the immobilizer
fInsert the ignition key into the ignition lock.
If the ignition is left on for more than 2 minutes
without starting the engine, the immobilizer is re-
activated.
fIf this happens, turn the ignition key back to the
3 position before starting the engine.
Please observe the chapter “IGNITION/STAR-
TER SWITCH WITH ANTI-THEFT STEERING
LOCK” on Page 68.
Switching off the immobilizer
fRemove ignition key.Security Wheel Bolts fIf wheels have to be removed during a work-
shop visit, do not forget to hand over the so-
cket for the security wheel bolts along with the
car key.

Safety Belts
Warning!
Always make sure your and your passenger’s
safety belts are properly fastened while the
vehicle is in motion.
Failure to follow safety belt warnings may re-
sult in serious personal injury.
fFor your and your passenger’s protection, use
safety belts at all times while the vehicle is in
motion.
fUse appropriate child restraint systems for all
small children.
Proper wearing of safety belts
fS a f e t y b e l t s m u s t b e p o s i t i o n e d o n t h e b o d y a s
to restrain the upper body and lap from sliding
forward. Improperly positioned safety belts
can cause serious personal injury in case of an
accident.
fThe shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fFor maximum effectiveness, the lap belt
should be worn low across the hips.
fPregnant women should position the belt as
low as possible across the pelvis. Make sure it
is not pressing against the abdomen. fBelts should not be worn twisted.
fDo not wear belts over rigid or breakable ob-
jects in or on your clothing, such as eye glas-
ses, pens, keys, etc. as these may cause inju-
ry.
fSeveral layers of heavy clothing may interfere
with proper positioning of belts.
fBelts must not rub against sharp objects or da-
mage may occur to the belt.
fTwo occupants should never share the same
belt at the same time.
Care and maintenance
fKeep belt buckles free of any obstruction that
may prevent a secure locking.
fBelts that have been subjected to excesssive
stretch forces in an accident must be inspec-
ted or replaced to ensure their continued effec-
tiveness in restraining you.
The same applies to belt tensioner systems
which have been triggered.
In addition, the anchor points of the belts
should be checked.
fIf safety belts do not work properly, see your
authorized Porsche dealer immediately.
fI f t h e b e l t s s h o w d a m a g e t o w e b b i n g , b i n d i n g s ,
buckles or retractors, they should be replaced
to ensure safe operation. fDo not modify or disassemble the safety belts
in your vehicle.
fThe belts must be kept clean or the retractors
may not work properly.
Please observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 191.
fNever bleach or dye safety belts.
fDo not allow safety belts to retract until they
are completely dry after cleaning or this may
cause damage to the belt.
Belt tensioner Depending on the force of a collision, fastened
safety belts are tightened in an accident.
The belt tensioners are triggered in:
– Front, side and rear impacts
Note
The belt tensioner system can be triggered only
once; the system must be replaced afterward.
If there is a fault in the belt tensioner system, the
airbag light lights up.
Work may be performed on the belt tensioner sys-
tem only by an authorized Porsche dealer.
Smoke is released when the belt tensioners are
triggered. This does not indicate a fire in the vehic-
le.

An audio-visual warning system is interconnec-
ted with the driver’s safety belt.
Every time the ignition is turned on, the gong will
sound for about 6 seconds to remind driver and
passenger to buckle up.
In addition, the gong will sound if the vehicle speed
exceeds 6mph (10 km/h).
The safety belt warning light in the instrument
panel and on-board computer will go off as soon
as the driver has buckled up.
Inertia reel retractor The combination lap/shoulder belt with inertia reel
locking mechanism adjusts automatically to your
size and movements as long as the pull on the belt
is slow.
Rapid deceleration during hard braking or a collisi-
on locks the belt. The belt will also lock when you
drive up or down a steep hill or in a sharp curve,
otherwise, the shoulder belt will not inhibit your up-
per body movement. fAssume a comfortable sitting position.
The shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fTo fasten, grasp belt and pull the belt in a con-
tinuous slow motion across your chest and lap.
fInsert belt tongue into buckle on inboard side
of seat. Push down until it securely locks with
an audible click. Pull the belt to check.
fPull shoulder section to make sure belt fits snu-
gly across the pelvis.
fBelts should fit snugly across the pelvis and
chest. Make sure there is no slack in the belt.
fTo unfasten belt, push in release button (arrow)
on buckle. Belt tongue will spring out of buckle.
fTo release a latched belt, lean back to take the
body pressure off the belt.
fTo store lap/shoulder belt, allow the belt to re-
tract as you guide the latch to its stowed posi-
tion.

Child Restraint Systems Porsche recommends that all infants and children
be restrained in child restraint systems at all times
while the vehicle is in motion in accordance with
applicable laws.
The use of infant or child restraints is required by
law in all 50 states and the Canadian provinces.
The child restraint system should be one that com-
plies with U.S. Federal/Canadian Motor Vehicle
Safety Standards 213 and should be secured by a
lap belt or lap belt portion of a lap-shoulder belt or
for child seats equipped with the LATCH system
(Lower Anchorage and Tether for Children, also
known as ISOFIX) to the LATCH anchorages.
A statement by the seat manufacturer of compli-
ance with this standard can be found on the in-
struction label on the restraint and in the instruc-
tion manual provided with the restraint.
Note
The key switch for switching off the passenger’s
airbag and the LATCH attachment bracket are not
installed at the factory. This can be retrofitted.
fPlease see your authorized Porsche dealer.
Danger!
Risk of serious personal injury or death to the
child.
fFollow all child restraint instructions and war-nings in this manual.
– When using an infant or child restraint system,
be sure to follow all manufacturer’s instruc-
tions on installation and use.
– Infants and small children should never be held
on the lap, nor should they share a safety belt
with another occupant while the vehicle is in
motion.
– Children too big for child restraint systems
should use regular safety belts. A shoulder belt
can be used providing it does not cross the
face or the neck of the child.
– The airbag deactivation device installation re-
quires special programming available only
from your authorized Porsche dealer.
– Your authorized Porsche dealer will be glad to
advise you about the installation possibility for
a Porsche child restraint system which allows
deactivation of the passenger’s airbags.
Danger!
The use of a child restraint system in the pas-
senger seat without airbag deactivation can
result in serious personal injury or death to
the child from an airbag deployment.
To reduce risk of injury from an inflating air-
bag in an accident, Porsche strongly recom-
mends:
fFor children up to a weight of 59 lbs. (27 kg),
the passenger’s airbag must be switched off if
a child retraint system is used on the passen-
ger’s seat.
The passenger’s airbag must be switched on for children weighing over 59 lbs. (27 kg).
fPlease observe the chapter “KEY-OPERATED
AIRBAG DEACTIVATION DEVICE” on Page 48.
