Faults are indicated by a warning light on the
tachometer.
fIn the following cases you should immedi-
ately consult an authorized Porsche
dealer in order to assure the airbag
system is functioning properly:
– If the warning light does not light up when the
ignition is switched on 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, as
well as on all airbag components.
For special recommendations on the use of child
restraints:
fPlease see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 49.
Child Restraint SystemsPorsche 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.
fPorsche recommends the use of L.A.T.C.H.
(Lower Anchorage and Tether for Children)
equipped Porsche child seat.
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.
You can obtain child seats that are LATCH
compatible at your authorized Porsche dealer.
fAlways observe the separate installation
instructions for your child seat.
The use of infant or child restraints is required by
law in all 50 US states and the Canadian provin-
ces. The child restraint system should be one that
complies with U.S. Federal/Canadian Motor Vehic-
le 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
(Lower Anchorage and Tether for Children, also
known as ISOFIX) to the LATCH anchorages.
A statement by the seat manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the
instruction manual provided with the restraint.

Warning!
Risk of accident due to impaired vision,
resulting in serious personal injury or death.
The outside air that is flowing in is not dried
in ECON mode. The windows may mist up.
fDo not switch on ECON mode in damp weather.
In ECON mode, the air-conditioning compressor is
switched off and this deactivates the cooling
function (e.g. to save fuel).
The air-conditioning compressor is always swit-
ched off at temperatures below 37.4 °F (3 °C).

Information on air-conditioning
compressorThe air-conditioning compressor:
– May switch off briefly to ensure sufficient
engine cooling if the engine is operating under
extreme load.
– Switches off automatically at temperatures
below approx. 37.4 °F (3 °C) and cannot be
switched on, even manually.
– Operates most effectively with windows
closed.
If the car has been in the sun for a long time,
however, it is a good idea to ventilate the
interior briefly with the windows open.
– Depending on the outside temperature and
humidity, condensation can drip from the eva-
porator and form a pool under the car.
This is normal and not a sign of leakage.
fIf uncooled air flows out when the lowest
temperature has been set (“LO”), switch off the
air-conditioning compressor and have the fault
remedied at an authorized Porsche dealer.
