Operation, Safety
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. If necessary, the seat-belt tensioners will 
be activated.
fPlease see the chapter “BELT TENSIONER” on 
Page 41.
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.

Maintenance, Car Care
Engine Oil RecommendationPorsche recommends  .
The right oil for your vehicle.1) Generally, you can find details of the 
manufacturer approvals on the oil containers or as 
a notice displayed by the retailer.
The current approval status is also available from 
your Porsche partner.2) SAE viscosity class - Example: SAE 0W - 40 
Specification 0W = Viscosity specification for 
low temperatures (winter).
Specification 40 = Viscosity specification for 
high temperatures.3) For all temperature ranges.4) For the temperature range over --13 °F (--25 °C).Always observe the following points:
– Use engine oils approved by Porsche only. This 
is a precondition for optimum and problem-free 
operation of your vehicle.
– Regular oil changes are part of servicing.
It is important that the service intervals, 
particularly the oil change intervals, are 
observed in accordance with the specifications 
in the “Maintenance” booklet.
– Oils approved by Porsche can be mixed with 
each other.
– Porsche engines are designed so that no oil 
additives may be used.
– A label is located in the engine compartment, 
which provides you with information on suitable 
oil for your engine.
Your Porsche partner will be pleased to advise 
you.
Oil changeThe engine oil has to be changed regularly at the 
intervals listed in your Maintenance Schedule. 
fPlease see the chapter “CAPACITIES” on 
Page 290.
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.  Complies with 
approval

Maintenance, Car Care
Air Filter A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear. 
Regular filter replacement is part of the routine 
maintenance service. 
fIn dusty conditions, check the filter element 
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-
ter into the passenger compartment is virtually 
free of dust, pollen, and unpleasant odors. 
fIf the outside air is polluted by exhaust fumes, 
press the circulating-air button.
A dirty filter can be the cause of reduced air flow: 
fHave filter replaced by your authorized 
Porsche dealer.
Regular filter replacement is part of the routine 
maintenance service.
Fluids/Oils for Manual 
Transmission and Porsche 
Doppelkupplung (PDK)The transmission fluids/oils have to be checked 
and changed at the intervals listed in your Mainte-
nance Schedule. 
fPlease see the chapter “CAPACITIES” on 
Page 290.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be 
damaged by even a tiny speck of dirt, only a clean 
funnel or spout must be used when adding fluid/
oil. 
We recommend that you have the fluids/oils 
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment. 
fIf you suspect an oil leak in the transmission, 
have your authorized Porsche dealer check it
