PASSENGER AIRBAG OFF indicator lamp
does not light up
– The passenger's airbag is active and ready for
operation.
– If the passenger's seat is not occupied, the
PASSENGER AIRBAG OFF indicator lamp will
also not light up, even though the passenger's
airbag is switched off.
Danger!
Risk of serious personal injury or death due
to the passenger airbag triggering uninten-
tionally.
When the ignition is on and the up to one-
year old child is seated in the child restraint
system on the passenger’s seat, the indicator
lamp “PASSENGER AIRBAG OFF” must be on.
If the “PASSENGER AIRBAG OFF” indicator
lamp does not light up, it could indicate a
fault in the system.
In this case:
fChild restraint systems facing forwards:
Install on the rear seats.
fChild restraint systems facing rearwards:
On vehicles with key-operated airbag deactiva-
tion device: Switch to position OFF.
fChild restraint systems facing rearwards:
On vehicles without key-operated airbag deac-
tivation device: Do not use a child restraint sys-
tem in the front passenger’s seat.fHave the fault remedied at your nearest author-
ized Porsche dealer.
Note
The key switch for switching off the passenger’s
airbag in combination with the LATCH attachment
bracket are not installed at the factory. They can
be retrofitted.
fPlease see your authorized Porsche dealer.
Faults are indicated by a warning light in the instru-
ment panel and a message on the on-board com-
puter.
fPlease observe the chapter “WARNINGS ON
THE INSTRUMENT PANEL AND THE ON-
BOARD COMPUTER” on Page 122.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag sys-
tem is functioning properly:
– If the warning light does not light up when the
ignition key is inserted or
– If the warning light does not go out once the
engine is running or
– If the warning light appears while driving.
Airbag maintenanceIn order to ensure long-term functioning, the air-
bag system must be inspected by an authorized
Porsche dealer at the intervals recommended in
your Maintenance Booklet.
Important information
If you sell your Porsche, notify the purchaser that
the vehicle is equipped with airbags, and refer
them to the chapter, “Airbag Systems“, in the
Owner's Manual (safety and disposal rules).
Further information on the airbag system can be
found on stickers attached to the sun visors.

Rollover Protection System The Rollover Protection System on the Cabriolet
consists of two supplemental safety bars that to-
gether with the front windshield frame help to cre-
ate occupant survival space in case of rollover. Be-
cause of the extreme and unpredictable forces
which can be encountered in a rollover, it is not
possible to guarantee that occupants will be pro-
tected from all contact with exterior objects or the
ground. However, the Rollover Protection System
is designed to maintain the occupant survival
space.
The Rollover Protection System is activated auto-
matically in the event of an accident or extreme
driving situation.
The protective devices are located behind each
rear seat and rapidly deploy within a fraction of a
second.
They can deploy under:
– Extreme tilting of the vehicle.
– Loss of ground contact (e.g. Going over the
crest of a hill at high speed).
Danger!
Risk of death or serious injury.
fDo not block area of supplemental safety bars
with objects.
In the event of a deployment event, such
objects could potentially prevent such deploy-
ment from occuring, or such objects could
impact the car occupants at high speed.
fDo not tamper with or work on wiring and or
components of Rollover Protection System.
fAll work regarding this system must be carried
out by your authorized Porsche dealer.
fCheck functions and periodic service intervals
according to maintenance schedule (see your
authorized Porsche dealer).
To avoid damage to the convertible top:
fIf the supplemental safety bars are extended
for any reason, do not open or close converti-ble top.Faults in the Rollover Protection System are indi-
cated by the airbag warning light in the instrument
panel.
Extension of the supplemental safety bars is no
longer ensured.
fSee your authorized Porsche dealer immedi-
ately and have the fault remedied.
Lowering the supplemental safety bars
after deployment fHave this work performed by an authorized
Porsche dealer.

Signal tones/function
When reverse gear is selected, the parking assist-
ant confirms that it is switched on by issuing a
short signal tone.
A detected obstacle is signalled by an intermit-
tent tone. The intervals decrease as the obstacle
is approached.
A continuous tone sounds when the distance be-
comes less than one foot. This continuous tone
can stop if the obstacle is approached closer than
one foot.
The radio volume should not be so loud as to
drown out the signal tones. Limits of ultrasonic measurement
The parking assistant system cannot detect:
– sound-absorbing obstacles (e.g. powder
snow),
– sound-reflecting obstacles (e.g. glass surfac-
es, flat painted surfaces)
– and very thin obstacles.
– Other ultrasound sources (e.g. pneumatic
brakes of other vehicles, jackhammers) can in-
terfere with detection of obstacles. Fault indication
The parking assistant system indicates a fault in
two ways:
– After reverse gear has been selected, the
short signal tone is followed by a continuous
tone of the same pitch:
This indicates that sensors are soiled or cov-
ered with ice.
– After reverse gear has been selected, the
short signal tone is followed by a continuous
tone with a much lower pitch:
This indicates a general system fault. Please
have the fault remedied at an authorized
Porsche dealer.

Controls, Instruments
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 booster 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.
When the vehicle is driven on salted roads for ex-
tended periods, the brakes should be washed
down thoroughly about every 2 weeks. An auto-
matic carwash facility cannot do this job properly.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
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.
fCautiously apply brakes to test brakes after being exposed.
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.
fHave the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
If the warning lights in the instrument panel and on-
board computer stay on when the engine is run-
ning or come on while driving, the brake pads are
worn, excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
Brake pads Wear 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.

Roof Transport System(Coupé only)
fPlease follow the separate instructions for fit-
ting the Roof Transport System.
fOnly use Roof Transport Systems from the
Porsche Tequipment product range or Roof
Transport Systems which have been tested
and approved for your car by Porsche.
Fitting normal commercially available luggage
racks is not possible.
The Porsche Roof Transport System allows you
to carry various sports and hobby equipment.
Your authorized Porsche dealer will be pleased to
tell you about the various different uses of the
Roof Transport System.
Safety notes!
fCompletely remove the Roof Transport System
before using an automatic car wash – risk of
damage to the vehicle!
fDo not exceed the maximum permitted pay-
load, the maximum permitted gross weight
and the maximum permitted axle loads.
Please observe the chapter “WEIGHTS COU-
PÉ” on Page 292.
fDistribute load evenly, with heavy items as low
as possible.
Items of luggage must not project beyond the
side of the load area.
fFix and secure every item to the basic carrier
with a rope or lashing strap (do not use elastic
rubber tensioners).
fBefore every journey, and at regular intervals
during long trips, check that Roof Transport
System and load are secure. Re-tighten if nec-
essary and secure additionally by locking.When the Roof Transport System is loaded, the
maximum speed depends on the nature, size and
weight of the load being carried.
Driving, braking and steering behavior change due
to the higher center of gravity and the greater
wind-resistant area. You should adapt your driving
style appropriately.
Since fuel consumption and noise are increased
with the Roof Transport System fitted, it should
not remain on the vehicle if not in use.

Maintenance, Car Care

Engine Oil Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually becom-
ing diluted with fuel or moisture, making it appear
that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater. If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked at every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if en-
gine rpm is above idle speed.
Engine Oil Level fPlease observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 198.
fRegularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please observe the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 118.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.2 liters.
Each segment of the display corresponds to ap-
prox. 0.4 liter.

Maintenance, Car Care
Oil change The engine oil has to be changed at the intervals
listed in your Maintenance Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 291.
We recommend that you have the engine oil
changed at your Porsche dealer, who has the re-
quired oils and the necessary filling equipment.
If you suspect an oil leak in the engine have your
dealer check it out immediately.
All current engine oils are compatible with each
other, i. e. when making an oil change it is not nec-
essary to flush the engine if you wish to use a dif-
ferent brand or grade of oil.
Since, however, each brand of oil has a special
composition, you should, if possible, use the
same oil brand if it becomes necessary to top up
between oil changes.
Porsche engines have long intervals between oil
changes. You can make best use of these long oil
change intervals by using multigrade oils since
these are largely independent of seasonal fluctua-
tions in temperature. If your vehicle is used frequently in stop-and-go
traffic in cold weather, the engine will not always
be properly warmed up.
Condensation from products of combustion may
accumulate in the oil. In this case, it is advisable
to change the oil more frequently so that your en-
gine once again has 100% efficient engine oil.
Engine oil performance class Engine oil is not only a lubricant, but also serves
to keep the engine clean, to neutralize the dirt
which penetrates into the engine through combus-
tion and to protect the engine against corrosion.
To perform these functions, the oil is provided with
additives which have been specially developed for
these functions.
The efficiency of an oil is expressed, for example,
by the API, ILSAC or ACEA classifications.
Viscosity Like all liquids, engine oil is viscous when cold,
and thin-bodied when warm. The viscosity of an oil
is expressed by its SAE class. For cold viscosity
(measured at temperatures below 32°
F/0°
C) the
SAE class is given as a number and the letter “W”
(as in winter), for hot viscosity (measured at
212°
F/100°
C) the SAE class is given only as a
number.
The viscosity of an oil is, therefore, always the
same if it has the same number of an SAE class.
Oils with two viscosities are called multigrade oils;
oils with only one viscosity are termed single-
grade oils.
Single-grade oils can not be used in your engine.
The viscosity of the engine oil for your Porsche
has to be chosen according to the ambient tem-
perature given in the engine oil recommendation
table.
