Operation, Safety 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 see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 158.
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.
For special recommendations on the use of child
restraints:
fPlease see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 50.

Operation, Safety
Porsche Stability Management
(PSM)PSM is an active control system for stabilization of
the vehicle approaching the performance limits of
driving maneuvers.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
The increased control that is provided should
not induce you to take greater risks with your
safety. The limits dictated by the laws of
physics cannot be overcome, even with PSM.
The risk of accidents due to inappropriate
speed cannot be reduced, even by PSM.
The driver bears the responsibility for all
driving maneuvers.
fAdapt your driving style to the prevailing road
and weather conditions.
fObey all traffic laws.
Sensors at the wheels, brakes, steering system
and engine continuously measure:
–Speed
– Direction of travel (steering angle)
– Lateral acceleration
– Rate of turn about the vertical axis
– Longitudinal accelerationPSM uses these values to determine the direction
of travel indicated by the driver.
PSM intervenes and helps to correct the course if
the actual direction of motion deviates from the
chosen course (steering-wheel position):
It brakes individual wheels as needed. In addition,
the engine power may be manipulated in order to
stabilize the vehicle.
The events below inform the driver of PSM control
operations and warn him/her to adapt his/her
driving style to the road conditions:
– The multifunctional information light on the
instrument panel flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as the PSM controls the
brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after the
brake pedal has begun vibrating.
Examples of PSM control operations– If the front wheels of the vehicle drift on a
bend, the rear wheel on the inside of the bend
is braked and the engine power is reduced if
necessary.
– If the rear of the vehicle swings out on a bend,
the front wheel on the outside of the bend is
braked.Additional braking functions– Pre-filling the brake system:
The brake system is prepared for possible
subsequent emergency braking if the acceler-
ator pedal is released suddenly and quickly.
The brake system is prefilled and the brake
pads are already applied gently to the brake
discs.
– Brake booster:
In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure neces-
sary for maximum deceleration at all 4 wheels.Advantages of PSM– Best possible traction and lane-holding ability
in all driving situations – even on road surfaces
with varying friction.

Setting temperaturefPress button F upwards or downwards
respectively.
To suit personal comfort, the interior temperature
can be adjusted between 61 °F and 85 °F/16 °C
and 29.5 °C.
Recommendation: 72 °F/22 °C.
If “LO” or “HI” appears on the display, the system
is operating at maximum cooling or heating pow-
er.
Automatic control is no longer active.
Note
If the preselected temperature is changed, the
blower speed can increase automatically in auto-
matic mode.
The desired temperature is reached more quickly
this way.
Sensors
To avoid affecting the performance of the air-con-
ditioning system:
fDo not cover the sun sensor on the instrument
panel or the temperature sensor C.fPress button A (switch on or off).
The windshield is defogged or defrosted as
quickly as possible.
Air flows to the windshield only.
The light-emitting diode in the button lights up.
AC OFF – switching compressor for air-
conditioning system on and offThe air-conditioning compressor switches off
automatically at temperatures below approx.
37 °F/3 °C and cannot be switched on, even
manually.
Whenever outside temperatures exceed approx.
37 °F/3 °C, the air-conditioning compressor is
always switched on in automatic mode.
The compressor can be switched off to save fuel,
but control comfort is then limited:
fPress AC OFF button D.
The compressor is switched off.
The light-emitting diode in the button lights up.
fIf the interior temperature is too high, switch
compressor back on or press AUTO button.
To dry incoming air in damp weather, do not
switch off the air-conditioning compressor.
This prevents fogging of windows.fPress button K upwards or downwards respec-
tively.
The preset blower speed is increased or
decreased.
The speed stages are indicated by a bar display.
If the button is pressed downwards at the lowest
blower stage, the blower and automatic control
are switched off. “OFF” will appear on the display
field.
Pressing the button upwards or pressing the
AUTO button switches the blower and automatic
control back on again.
Warning!
Risk of accident due to impaired vision,
resulting in serious personal injury or death.
In recirculating-air setting, the windows may
fog up.
fOnly select recirculating-air setting for short
periods.
fIf the windows fog up, switch recirculating-air
setting off immediately by pressing the
circulating-air button again and select the “Defrost windshield” function.
