Before driving off...
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/her 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 f Turn the engine off before you attempt any
checks or repairs on the vehicle.
f Be sure the tires are inflated correctly.
Check tires for damage and tire wear.
f See that wheel bolts are properly tightened
and not loose or missing.
f Check engine oil level, add if necessary.
Make it a habit to have engine oil checked with
every fuel filling.
f Check all fluid levels such as windshield
washer and brake fluid levels.
f Be sure the vehicle battery is well charged and
cranks the engine properly.
f Check all doors and lids for proper operation
and latch them properly.
f Check, and if necessary replace worn or
cracked wiper blades.
f See that all windows are clear and unob-
structed.
f Check air intake slots and area between lug-
gage compartment lid and windshield. Ensure
that these areas are free of snow and ice, so
the heater and the windshield wipers work
properly. f
If a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
f Child restraint systems will not fit into the
Sports bucket seat.
Do not install a child restraint system in the
Sports bucket seat.
The Sports bucket seat cannot be equipped
with the LATCH system and thus the airbag
system cannot be manually deactivated.
f Check all exterior and interior lights for opera-
tion and that the lenses are clean.
f Check the headlights for proper aim, and if
necessary, have them adjusted.
f Check under the vehicle for leaks.
f Be 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.

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”
on Page 72.
Switching on the immobilizer
f Remove ignition key.Security Wheel Bolts fIf wheels have to be removed during a work-
shop visit, do not forget to hand over the sock-
et for the security wheel bolts along with the
car key.

sult in serious personal injury or death.
f For your and your passenger’s protection, use
safety belts at all times while the vehicle is in
motion.
f Use appropriate child restraint systems for all
small children.
Proper wearing of safety belts
f S 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 or death in
case of an accident.
f The shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
f For maximum effectiveness, the lap belt
should be worn low across the hips.
f Pregnant women should position the belt as
low as possible across the pelvis. Make sure it
is not pressing against the abdomen. f
Belts should not be worn twisted.
f Do not wear belts over rigid or breakable ob-
jects in or on your clothing, such as eye glass-
es, pens, keys, etc. as these may cause injury.
f Several layers of heavy clothing may interfere
with proper positioning of belts.
f Belts must not rub against sharp objects or
damage may occur to the belt.
f Two occupants should never share the same
belt at the same time.
Care and maintenance
f Keep belt buckles free of any obstruction that
may prevent a secure locking.
f Belts that have been subjected to excessive
stretch forces in an accident must be inspect-
ed 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.
f If safety belts do not work properly, see your
authorized Porsche dealer immediately.
f I 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.
f Do not modify or disasse mble the safety belts

may not work properly.
Please see the chapter “CAR CARE INSTRUC-
TIONS” on Page 203.
f Never bleach or dye safety belts.
f Do 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 an impact, fastened
safety belts are tightened in an accident.
The belt tensioners are triggered in:
– Front, side and rear impacts of sufficient
severity.
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 warning light lights up.

Operation, Safety
Child Restraint SystemsfDo not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be
equipped with the LATCH system.
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.
Use only child restraint systems with the LATCH-
system recommended by Porsche. These sys-
tems have been tested and adjusted to the interior
of your Porsche and the appropriate child weight
groups. Other systems have not been tested and
could entail an increased risk of injury or death.
You can obtain child seats that are LATCH compa-
tible at your authorized Porsche dealer.
f Always see the separate installation
instructions for your child seat.
The use of infant or child restraints is required by
law in all 50 states of the U.S. and all Canadian
provinces. The child restraint system should be
one that complies with U.S. Federal Motor Vehicle
Safety Standards 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 sytem ( Lo-
wer 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.
Danger!
The use of a child restraint system in the pas-
senger seat can result in serious personal in-
jury or death to the child from an airbag
deployment.
To reduce risk of injury from an inflating air-
bag in an accident, Po rsche strongly recom-
mends:
f Please see the chapter “PASSENGER AIRBAG
OFF INDICATOR LAMP DOES NOT LIGHT UP”
on Page 47.
f Please see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 50.
f Do not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be equipped with the LATCH system.
Note
The key switch for switching off the passenger’s
airbag and the LATCH attachment bracket are not
installed at the factory. Th ey can be retrofitted (not
on vehicles with Sports bucket seats).
f Please see your authorized Porsche dealer.
Danger!
Risk of serious personal injury or death to the
child.
f Follow all child restraint instructions and warnings 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 th ey 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.
– Choose a child restraint system according to the weight of the child.
– Child restraint systems that are damaged or h a v e b e e n h e a v i l y s t r e s s e d i n a n a c c i d e n t m u s t
be replaced immediately.
– Children could be endangered in a crash if their child restrains are not properly secured in the
vehicle.
– Do not affix things to child restraint systems or cover it with other materials.

Operation, Safety
Child restraint system for children older than
one year
Your vehicle is equipped with a weight sensing sys-
tem for the passenger's seat in accordance with
U.S. Federal Motor Vehicl
e Safety Standard 208.
Depending on the weight acting on the passen-
ger's seat, the passenger's airbag will automati-
cally be switched on or off.
Small adult passengers
Make sure that the PASSENGER AIRBAG OFF indi-
cator lamp does not light up. Danger!
Risk of serious personal injury or death due
to the passenger airbag not triggering.
When the ignition key is inserted on and the
small adult passenger is seated on the pas-
senger’s seat, the indicator lamp ”PASSEN-
GER AIRBAG OFF“ must be off.
If the ”PASSENGER AIRBAG OFF“ indicator
lamp lights up, it could indicate a fault in the
system.
In this case:
f Do not carry a passenger in the passenger’s
seat.
f Have the fault remedied at the nearest authori-zed Porsche dealer.
Automatic locking retractorfDo not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be
equipped with the LATCH system.
The safety belt for the passenger is equipped with
an automatic locking retractor for securing the
child restraint system. When activated, this retrac-
tor allows you to securely fasten the child restraint
system in place so that inadvertent movements
will not occur.
Before transporting a child on the passenger seat:
f Please see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 50.
Danger!
Risk of serious personal injury or death to the
child, when excessive force is acting on the
passenger's seat due to the seat belt.
In such cases, the passenger's airbag can be
switched on unintentionally.
f After fastening the child restraint system, do
not adjust the seat.
f Check the condition of the passenger’s airbag
shown by the indicator lamp in the central con-sole. Activating the automatic locking retractor
1. If a child restraint system must be fastened to
the passenger's seat, adjust the passenger's
seat as far away from the airbag as possible.
2. Fasten child seat.
3. Pull the safety belt retractor completely out. At this point the locking mechanism is activated.
4. Insert the safety belt tongue into the buckle
and make certain that it is properly latched.
Make no more adjustments to the seat.
5. Allow the safety belt to retract until it is tight on the child restraint system. You may further tigh-
ten the belt by pulling on it to allow more of it
to retract.
Make sure that excessive seat belt forces do
not occur by moving the seat with the child
seat installed.
Releasing the safety belt
1. Unbuckle the safety belt latch.
2. Then make certain that the belt has fully retrac- ted. At this point the au tomatic locking feature
will be disengaged.
