Maintenance and Car Care

FuelWhen the ignition is on, the fuel level is displayed
on the instrument panel.
fPlease see the chapter “FUEL GAUGE” on
page 111.
Warning!
Fuel is highly flammable and harmful to
health.
f Fire, open flame and smoking are prohibited
when handling fuel.
f Avoid contact with skin or clothing, since injury
to your skin may occur.
f Do not inhale fuel vapors, since they may make
you ill and possibly cause death if inhalation is
prolonged and occurs in a closed space.
To prevent damage to the emission control
system and engine:
f Never drive the tank dry.
f Avoid high cornering speeds after the warning lights have come on.
f Please see the chapter “FUEL ECONOMY” on
page 264. To avoid permanent damage
to the functionality of
the catalytic converters and oxygen sensors, use
unleaded fuel only.
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON is used.
If unleaded fuels with octane ratings of less than
98 RON/88 MON are used, the engine’s knock
control automatically adapts the ignition timing.
Porsche recommends that you use fuel with
at least 95 RON/85 MON in your vehicle.
The emission control system can be damaged in
various ways (e.g. fueling incorrectly, shortage of
fuel, tow-starting).
f Please see the chapter “HOW EMISSION
CONTROL WORKS” on page 263. Note on operation
Information on the fuel quality can normally
be found on the pump.
If this is not the case, ask a fuel station attendant.
If the recommended fuel
is not available, you
can also use unleaded regular fuel (91 RON/
82.5 MON) in an emergency.
However, this could reduce performance and
increase fuel consumption.
f Avoiding driving at full throttle.
In some countries the available fuel quality may
not meet requirements and can result in coking
around the inlet valve.
In this case, the fuel may be mixed with the
additive sold and recommended by Porsche after
consulting a authorized Porsche dealer.
Porsche part number 000 043 206 89.
f Observe the instructions and mixture ratios
stated on the container.
It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the “Maintenance” booklet.

Maintenance and Car Care
Cleaning air bag covers
Danger!
Risk of serious or fatal injury from impaired
operation of the air bag system caused by
incorrect cleaning.
f While it is appropriate to use normal surface
cleaning methods on the interior of your
vehicle, do not undertake deep cleaning of air
bag-related components, such as the
padded covers on the steering wheel,
the underside of the instrument panel,
front seats, roof pillars, roof liners and the
rear interior trim panels, and around the
seat backrest.
f Have your authorized Porsche dealer to clean these components.
Cleaning fabric liningsfFabric linings on pillars, roofliner and sun
blinds, etc. must be cleaned only using
suitable cleaning agents or a suitable dry
foam and a soft brush.
Alcantara careDo not use leather care products to
clean Alcantara.
For regular care, it is sufficient to clean the
cover with a soft brush.
Strong abrasion or rubbing when cleaning will
produce a lasting change to the surface.
Cleaning when lightly soiled
f Wet a soft cloth with water or a neutral
soap solution and wipe off the dirt.
Cleaning when heavily soiled
f Wet a soft cloth with lukewarm water or diluted
white spirit and dab the dirt from the outside
in.Cleaning the seat beltsfUse mild detergent to clean soiled belts.
f When drying, avoid direct sunlight.
f Only use suitable cleaning agents.
f Do not tint or bleach the belts.
The belt fabric could be weakened,
thus affecting safety.
Storing your PorscheIf you wish to keep your Porsche off the road for
a lengthy period, we recommend that you contact
your authorized Porsche dealer.
They will be glad to advise you about the
necessary measures, e.g. corrosion prevention,
care, maintenance and storage.
Further important information on laying up your
Porsche can be found in other sections.
fPlease see the chapter “BATTERY” on
page 303.
For information on locking the vehicle when
the battery is disconnected:
f Please see the chapter “NOT ALL VEHICLE
DOORS ARE LOCKED” on page 36.
Minor Repairs
305
Replacing the batteryThe service life of the battery is subject to normal
wear; it depends greatly on care, climatic
conditions, and driving conditions (distances,
loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement. Only
this battery meets the spec ific requirements of
the vehicle.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after a fully
discharged battery is charged, the PSM warning
light lights up on the instrument panel and
a message appears on the multi-function display
in the instrument panel to indicate a fault.
This fault can be corrected with a few
simple steps:
1. Start the engine. To do this, turn the igni tion key or the control
unit (on vehicles with Porsche Entry & Drive)
to ignition lock position 2, twice .
2. With the vehicle stationary, perform a few steering movements to the left and right and
then drive a short distance in a straight line
until the PSM warning light goes out and the
message is erased from the multi-function
display in the instrument panel.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer to have the fault corrected.
4. After the warnings go out: Stop the vehicle in a suitable place.
5. Store the end position for the power windows. For information on storin
g the end positions for
the power windows:
f Please see the chapter “STORING END
POSITION OF THE DOOR WINDOWS AFTER
CONNECTING THE VEHICLE BATTERY” on
page 88.
6. Teach tires on vehicles with Tire Pressure Monitoring.
For information on teaching the Tire Pressure
Monitoring system:
f Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.
7. Store end position on vehicles with a slide/ tilt roof.
For information on storing the end position for the
slide/tilt roof:
f Please see the chapter “STORING END
POSITION OF THE SLIDE/TILT ROOF” on
page 90.

4. Leave the engine of the donor vehicle running at a higher engine speed.
5. Start the engine. An attempted start using jump leads should
not last more than 15 seconds. Then wait for
at least one minute.
6. Disconnect the negative lead from the ground
point for jump-lead starting ( –) first, then from
the negative terminal of the donor battery.
7. Disconnect the positive lead from the positive terminal of the donor ba ttery first, then from
the positive terminal for jump-lead starting ( +).
8. Close the cap on the posi tive terminal for jump-
lead starting ( +).Charging the batteryAutomotive 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 allo ws rapid formation of
sulfates, leading to premature deterioration of the
plates.
Danger!
Hydrogen gas genera ted by the battery
could cause an explosion, resulting in
serious personal injury or death.
f Charge battery in a well ventilated area.
f Never charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a
frozen battery to thaw out first.
f If 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 doctor.
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
f Always observe the instructions provided by
the charger manufacturer.
1. Connect the charger to the jump-lead starting terminals.
Only plug into the mains and switch the
charger on when it is connected up correctly.
2. Switch on the charger.
3. After charging the battery, first switch off the charger and then disconnect it.
f Please see the chapter “PUTTING VEHICLE
INTO OPERATION” on page 305.
Changing the Remote Control
BatteryNote
f Please observe the regulations for disposing
of batteries.Car keyIf the battery in the remote control becomes too
weak, the message “Replace ignition key battery”
will appear on the multi-function display in the
instrument panel.
The battery should be changed in this case.
