System not active –
Too many wheel transmittersTire pressure monitoring detects more than 4 wheel transmit-
ters (winter wheels in the luggage compartment, for example).
Tire pressure monitoring will reactivate itself after the additional
wheel transmitters have been removed.
No monitoring – System learning After the tire type and size are selected in the tire pressure
menu, the system re-learns the tires.
Wheel change? Check settings Display after a wheel change without changed settings in the tire
pressure menu. Select tire type and size.
When vehicle stops: Hit selection Displayed after a flat tire if the system was not informed about
the work performed.
Make a selection on the multi-purpose display when the vehicle
is stationary.
Monitoring off Tire pressure monitoring was intentionally deactivated.
Tire pressure monitoring can be switched on or off on the
multi-purpose display.
Engine temperature too high Switch engine off and let it cool.
Check coolant level. Add coolant if necessary.
Check coolant level Switch engine off and let it cool.
Check coolant level. Add coolant if necessary.
Battery/generator warning Stop in a suitable place and switch engine off. Do not continue
driving.
Have the fault remedied at an authorized Porsche dealer.
Starting engine The battery discharges if the engine is not running and loads are
switched on.
Start the vehicle or switch the loads off.
Electrics – Loads – Switch-off Vehicle electrical system is overloaded. Certain loads (e.g.
heated rear window, seat heating) will be switched off.

ABS
(Anti-lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the driv-
er’s responsibility to adapt his driving style and
maneuvres in line with road and weather condi-
tions, as well as the traffic situation.
The increased safety that is provided should not in-
duce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with ABS.
Risks of accident due to inappropriate speed can-
not be reduced by ABS.
ABS ensures
–Full steering control
The vehicle remains steerable
–Good driving stability
No skidding due to locked wheels
–Optimum braking distance
Shorter stopping distances in most cases
–Lock prevention
No flat spots on the tiresFunction
The decisive advantage of ABS is in the driving
stability and maneuvrability of the vehicle in
hazardous situations, even during heavy braking
while cornering.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until shortly
before the vehicle stops.
The ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable to
extremely rapid cadence braking.
The pulsating brake pedal and a “rattling noise”
warn the driver to adapt his driving speed to the
road conditions.Warning light
If the ABS warning lights light up in the instrument
panel and on the multi-purpose display of the in-
strument panel while the engine is running, the
ABS has switched off because of a fault.
In this event, the braking system will operate with-
out lock prevention,as in cars without ABS.
fAdapt your driving style to the changed brak-
ing behavior.
fThe ABS must be checked immediately at an
authorized Porsche dealer. This is necessary
in order to prevent the occurrence of further
faults whose effects cannot be defined.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with non-approved dimensions can
lead to different wheel speeds, causing the ABS to
switch off.

Maintenance, Car Care
Storing your PorscheIf you intend to store your Porsche for a prolonged
period, please consult your authorized Porsche
dealer. The staff will be glad to advise you on the
most suitable and necessary methods.
fClean your vehicle thoroughly inside and out-
side. Clean the engine compartment. The un-
der carriage and chassis components should
be free of dirt and salt deposits.
fFill up the fuel tank.
fChange the oil and oil filter, and run the engine
for several minutes.
fIncrease the tire pressure to 58 psi (4 bar).It is
not recommended to lift the vehicle, due to the
possibility of corrosion on shock absorber pis-
ton shafts.The vehicle should be moved slight-
ly, approximately every four weeks, to prevent
flat spot on the tires.Climate control
The air conditioning system should be in good
working condition and fully charged.
Windshield/Headlight washer
fCheck and correct antifreeze/cleaning solution
level as necessary.
Electrical system
fRemove the battery from the vehicle and store
it in a cool dry place, not on a cement floor.
When the battery is disconnected, the alarm
system is deactivated.
fRecharge the battery every 3 months. If the
battery remains in the vehicle with the cables
connected, it is necessary to check, remove
and recharge the battery every 2-3 weeks.
Do not fast charge the battery.
fPlease observe the chapter “CHARGE STATE”
on Page 332.Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs.
(500 grams) each placed on the floor carpets.
Windows, doors, lids and roof must be closed.
The air vents should be opened.
