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
serious personal injury or death.
fDo not adjust seats while the vehicle is in
motion.
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, etc.
when the seat is adjusted or folded back or
forward.
fAdjust the seat so that the seat backrest is not in contact with any other object.
The driver and passenger seat provide integrated
head restraints in the backrests. The head
restraints are not adjustable. 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 adjus-
ting the driver’s seat to suit individual
requirements:
1. Adjust the seat until, with the clutch pedal fully
depressed, your 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.

longitudinally.
4. Swivel locking lever back until you feel it
engage.
If necessary, move steering wheel slightly
longitudinally.
Sun VisorsfSwing the sun visors down to prevent glare

Lowering front axle fPress button in the center console.
The vehicle is lowered to the basic level.
The light-emitting diode in the button and in the
tachometer goes out.
Caution!
Risk of damage through bottoming out the
vehicle.
fDo not lower the vehicle when it is positioned above an obstacle.
Notes on operation
Warning messageFront axle lift system faults are indicated by
a warning message on the on-board computer.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.
– When raised, the damping properties of the
front axle change and noise may be heard in
the area of the front axle coil springs during
steering movements.
– The doors must be closed when lowering the
front axle.
–The blowing-off procedure may result in
system-related hissing noise. This does not
represent a malfunction in the lift system.– During extended vehicle immobilization, the
pressure accumulator may be completely
emptied. In this case, the first time the axle is
raised, a period of up to 2 minutes may elapse
before the vehicle height is reached and “LIFT”
is displayed.
– A flashing LED in the button indicates that the
system is currently not available. Possible
causes may be:
> Automatic overload protection is active.
The system will be available again
following a brief cooling-down phase.
The cooling-down phase may be
extended when outside temperatures
are very high.
> The speed threshold of 30 mph
(50 km/h) has been exceeded. The
system will be available again once the
speed falls below the threshold.
> If automatic lowering is actuated by
exceeding a speed of approx. 30 mph
(50 km/h) in combination with hard
acceleration, the required lowering
duration may mean that “LIFT not
lowered” is displayed. The display goes
out again as soon as the front axle has
been completely lowered.

Decals
Caution!
Risk of damage due to separation of the
decal films when using high-pressure
cleaning equipment or steam cleaners.
fDo not use high-pressure cleaning equipment or steam cleaners to clean decal films.
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
thoroughly 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
effect.
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
scratching 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
water to rinse away loose dirt.
fAfter washing, rinse the car with plenty of
water and then dry with a chamois leather.
Do not use the same chamois leather for
drying 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 permitting). Automatic car washes
fPlease see the chapter “WIPER BLADES” on
Page 173.
Optional add-on parts or parts which project
beyond 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:
– Windshield wipers (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External antennas (always unscrew)
– 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
getting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
fPlease consult the operator before using
automatic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills.
