Luggage Compartment, Loadspace and Storage If aftermarket systems are installed by non-dealer-
ship technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car
Warranty.
fConsult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfe-
rence caused by buildings, landscape and wea-
ther is unavoidable. It may become particularly
difficult to hear when using the hands-free function
due to external noise such as engine and wind
noise.
Automatic car-wash
fUnscrew external antennas before using an au-
tomatic car-wash.
Porsche Communication
Management (PCM)
Warning!
There is danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting
procedures only with the vehicle stationary.
fIf it is necessary to operate these components
while the vehicle is in motion, use the function keys on the multi-functional steering wheel.
fRefer to the separate operating instructions
before putting the PCM into operation.
When put into operation for the first time, a
distance of approx. 3 miles (5 km) must be driven
in order for the navigation system to complete the
process of fine calibration. The same applies
when the tires are changed (e.g. summer/winter
tires) or new tires fitted. Full location accuracy is
not yet achieved during the fine-calibration
process.If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes after
being switched on before it determines the current
location.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational once more.
Satellite radioYou must have the satellite radio activated before
you can put it into operation. You will need a
contract with a provider in order to use this radio.
fRefer to the separate radio operating instruc-
tions before putting into operation.

Power Steering
Warning!
Risk of accident resulting in serious personal
injury or death. When the engine is stationary
(e.g. when on tow) or the hydraulic system
fails, there is no assistance for steering.
Therefore, substantially more force will have
to be exerted.
fExercise great care when on tow.
fHave the fault remedied at your nearest authorized Porsche dealer.
The flow noise heard at full steering lock is design-
related and does not indicate a defect in the
steering system.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 250.
Checking hydraulic fluidfUse only hydraulic fluid authorized by
Porsche.
fCheck the fluid level with the engine stopped
and cold (engine temperature approx. 68 °F or
20 °C).
1. Remove cover A.2. Open the reservoir cap.
3. The fluid level should lie between the MIN and
MAX marks on the dipstick.
Add hydraulic fluid if necessary.
4. Close cap carefully.
5. Put on cover A.
6. Close engine compartment lid.
Note on operation
fIf the fluid level drops significantly, please have
the cause remedied immediately by an
authorized Porsche dealer.

Maintenance and Car Care
Warning!
Moisture which gets on the brakes during a
car wash can reduce braking efficiency or
make the brake pull unevenly which could
increase the danger of an accident, causing
serious personal injuries or death.
fAfter washing the vehicle, test the brakes and
steering and briefly brake the discs dry.
When doing so, make sure that vehicles travel-ling behind you are not affected.
Automatic car washes
fPlease see the chapter “WIPER BLADES” on
Page 261.
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:
– Windshield wipers and rear wiper (always
switch them off – wiper stalk in position0 – to
prevent them wiping unintentionally in intermit-
tent or sensor operation).
– Door mirrors (always fold in).
– External antennas (always unscrew).
– Roof Transport System (always remove com-
pletely).
– Off-road roof-mounted headlights (always
remove completely).
– Spoiler.
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage).
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.
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.

Leather careThe natural surface markings of leather,
e.g. creases, healed scars, insect sting marks,
structural differences and slight variations in
shade and grain add to the attractiveness of the
high-quality natural leather product.
Observe the following care instructions:
Caution!
The leather will be damaged by the use of
unsuitable cleaning and care agents and by
inappropriate treatment.
fDo not use caustic cleaners or hard cleaning
objects!
fPerforated leather must under no circum-stances get wet on its reverse side.
fAll types of leather should be cleaned regularly
to remove fine dust using a soft, damp, white
woollen cloth or a commercially available
microfibre cloth.
fRemove heavy contamination with a leather
cleaner.
Please always follow the instructions for use
given on the containers.
We recommend the Porsche leather care
product.
fOnce cleaned, leather (particularly the heavily
stressed leather seats) must be treated only
with Porsche leather care product.
Carpets and matsfUse only a vacuum cleaner or a medium stiff
brush.
fRemove stains and spots with Porsche stain
remover.
The Porsche range of accessories includes floor-
mats to protect the carpets in summer and winter.
Warning!
Risk of an accident resulting in serious
personal injury or death.
fAlways check the movement of the pedals
before driving and make sure that they are not
obstructed by a floor mat or any other object.
fSecure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle – do not lay them
loosely in the vehicle.
Your Porsche dealer will be glad to offer you
floor mats of correct size including a securing possibility.
Cleaning airbags covers
Danger!
There is a danger of serious personal injury
or death if the airbag system is impaired by
improper cleaning work.
fDo not make any modifications whatsoever on
individual components such as the padded
covers of the steering wheel, the passenger
side of the dashboard, the front seats, the roof
pillars and the rooflinings.
fLet your authorized Porsche dealer clean these components.
Cleaning fabric liningsFabric linings on pillars, headliner and sun visors,
etc., must be treated only using suitable cleaning
agents or a suitable dry foam and a soft brush.

Battery chargingAutomotive batteries loose their efficiency when
not in use. The charge available in your battery can
be measured with a battery hydrometer. We
recommend that the battery voltage be tested by
your Porsche dealer who has the appropriate
equipment.
If the car is not driven for prolonged periods, the
battery must be charged at least every 6 weeks.
A discharged battery allows rapid formation of sul-
fates, leading to premature deterioration of the
plates.
Danger!
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
fCharge battery in a well ventilated area.
fNever charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
fIf you get electrolyte, which is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-tor.Note
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
fAlways observe the instructions of the charger
manufacturer.
fWhen charging the battery, ensure adequate
ventilation.
1. Check the acid level of a low-maintenance
battery.
2. Connect charger to the jump starting points.
Only plug into the mains and switch the
charger on when it has been correctly
connected up.
3. Switch on the charger.
4. After charging, switch off and disconnect the
charger.
5. Check the acid level of a low-maintenance
battery.
After charging the battery After the battery is connected or the completely
discharged battery is charged, the PSM warning
light lights up on the instrument panel and a
message appears on the multi-purpose display of
the instrument panel to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
To do this, turn the ignition key or the control
unit (on vehicles that have Porsche Entry &
Drive) to ignition lock position 2 twice.
2. Perform a few steering movements to the left
and to the right when vehicle is standing and
drive a short distance in a straight line until the
PSM warning light goes out and the message
is erased from the memory of the multi-
purpose display of the instrument panel.
3. If the warnings does not go out, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied by an authorized
Porsche dealer.
