Operation, Safety
Seat Adjustment and Head
Restraints
Warning!
The seat may move unexpectedly if you
attempt to adjust while driving. This could
cause sudden loss of control, resulting in se-
rious personal injury or death.
fDo not adjust seats while the vehicle is in mo-
tion.
The backrest locks must be engaged at all
times while the vehicle is in motion.
Safety belts only offer protection when the
backrest is upright and the belts are properly
positioned on the body.
Improperly positioned safety belts or safety
belts worn by passengers in an excessively
reclined position can cause serious personal
injury or death in an accident.
fDo not operate the car with the driver or
passenger backrests excessively reclined
(see “Seat position”).
Risk of injury if persons or animals are in the
movement range of the seat during seat
adjustment.
fAdjust the seat so that no-one is put at risk.
Caution!
Risk of damage to windshield, sun visor,
windstop, etc. when the seat is adjusted or
folded back or forward.
fAdjust the seat so that the s e a t b a c k re s t i s n o t in contact with any other object.
The driver and front passenger seats provide
integrated head restraints in the backrests. The
head restraints are not adjustable. The rear seats
do not provide head restraints. Warning!
All occupants, including the driver, should not
operate a vehicle or sit in a vehicle's seat until the
head restraints and backrests, respectively, are
placed in their proper positions so that the risk of
neck injuries is minimized in the event of a crash.
For proper positioning of the head restraint, the
seatback's inclination should be adjusted such
that the head restraint is in an upright position.
Driver and passengers should be seated upright
and in the center of their seats.
Seat positionAn ergonomically correct sitting position is
important for safe and fatigue-free driving.
We recommend the following procedure for adjust-
ing the driver’s seat to suit individual
requirements:
1.Vehicles with manual transmission:
Adjust the seat until, with the clutch pedal fully
depressed, your leg remains at a slight angle.
Vehicles with Porsche Doppelkupplung
(PDK):
Adjust the seat until, with your left foot on the
footrest, your left leg remains at a slight angle.
2. Rest your outstretched arm on the steering
wheel.
Set the backrest angle (not applicable for
Sports bucket seat) and the steering-wheel
position so that your wrist rests on the outer
rim of the steering wheel. At the same time,
the shoulders must still be in noticeable
contact with the backrest.
3. Adjust the seat height (not applicable for
Sports bucket seat) to give yourself enough
headroom and a good overview of the vehicle.
4. Electrically adjustable seat:
Adjust the seat angle until your thighs rest
lightly on the seat cushion.

Rear Seat BackrestsExtra storage space is gained by folding the rear
seat backrests forward.
Folding forward
fPull lever forward and fold the backrest
forward.
Folding back
fTilt the backrest back until you feel it click into
place. When doing so, make sure that the seat
belt is properly routed (see figure).Cabriolet
fDo not fold up the rear seat backrests with the
windstop installed.
Steering Wheel Adjustment
Warning!
Risk of accident.
The steering wheel may move further than
desired if you attempt to adjust it when
driving.
You can lose control of the vehicle, causing
serious personal injury or death.
fDo not adjust the steering wheel when driving.
Adjusting steering wheel height and
longitudinal direction1. Insert ignition key fully into ignition lock.
2. Push the locking lever downwards.
3. Adjust steering wheel to fit the chosen
backrest angle and your seat position by
moving the steering wheel up or down and
longitudinally.
4. Swivel locking lever back until you feel it en-
gage.
If necessary, move steering wheel slightly lon-
gitudinally.

Safety belt height adjustment(Coupé and Targa)
The height of the belt deflectors for the driver’s
seat and passenger’s seat can be adjusted.
Adjust the height of the safety belt so that it runs
across the middle of the shoulder, not against the
neck.
Adjusting belt height
fUpward – push belt deflector up.
fDownward – press button (arrow) and move
belt deflector.
Cleaning the safety beltsIf it becomes necessary to clean the belts, you
can use any mild washing agent. Allow the belts to
dry prior to retracting, but avoid direct sunlight.
fOnly use suitable cleaners. If unsuitable
cleaners are used or any attempt is made to
dye or bleach the belts, the webbing may be
weakened and thus constitute a safety risk.
Maintenance, Car Care
225
Washing The best method of protecting your car from the
damaging effects of the environment is frequent
washing and the application of a preservative. The
underside of your vehicle should also be thorough-
ly washed for cinders, salt or sanding at winter’s
end.
The longer salt, road dust and industrial dust,
dead insects, bird droppings or substances from
trees (resin, pollen) are allowed to remain on the
bodywork, the more serious is their harmful ef-
fect.
New cars should be washed carefully with plenty
of clear water to protect the new paint work. Dark
paint finishes show up the smallest of surface
damage (e.g., scratches) more readily than lighter
colors.
Dark colors are also more susceptible to scratch-
ing because of the composition of their pigments
and require particularly careful paint care.
fDo not wash your car in bright sunlight or while
the bodywork is still hot.
fWhen washing by hand, use abundant water, a
soft sponge or wash brush, and Porsche car
shampoo.
fBegin by spraying the body thoroughly with wa-
ter to rinse away loose dirt.fAfter washing, rinse the car with plenty of wa-
ter and then dry with a chamois leather.
Do not use the same chamois leather for dry-
ing as you use for cleaning the windshield and
windows.
Warning!
Moisture which gets on to the brakes during
a car wash can reduce braking efficiency or
make the brakes pull unevenly which could
increase the danger of an accident, causing
serious personal injuries or death.
fAfter washing the car, test the brakes and
steering and briefly brake the discs dry.
When doing this, take care not to hamper other
road users behind you (traffic conditions per-mitting).
Automatic car washes
fPlease see the chapter “WIPER BLADES” on
Page 223.
Optional add-on parts or parts which project be-
yond the contours of the vehicle may be damaged
by design features (e.g. brushes) of automatic car
washes.The following parts are particularly
susceptible to damage:
– Convertible top (hot wax treatment cannot be
used, as the wax attacks the convertible top
material)
– Windshield wipers (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External antennas (always unscrew)
– Roof Transport System (always remove com-
pletely)
– Rear spoiler
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage)
– High-gloss wheels (to prevent these from get-
ting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
fPlease consult the operator before using auto-
matic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills.
Note
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.

The DOT symbol indicates that the tires com-
ply with the requirements of the US Depart-
ment of Transportation and provides informa-
tion about:
– first two-digit code means manufacturer’s iden-
tification mark.
– second two-digit code means tire size.
– third four-digit code means tire type code.
– fourth four-digit code means date of manufac-
ture.
If, for example, the last four numbers read
0204, the tire was produced in the 2nd week
of 2004.
