Power Steering
Warning!
Risk of accident. When the engine is station-
ary (e.g. when on tow) or the hydraulic sys-
tem 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 author-ized Porsche dealer.The flow noise heard at full steering lock is design-
related and does not indicate a de fe ct in the ste er-
ing system.
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.
fIf the fluid level drops significantly, please have
the cause remedied immediately by an author-
ized Porsche dealer.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease observe the chapter “EXERCISE
EXTREME CAUTION WHEN WORKING ON YOUR
VEHICLE” on Page 260.

Winter operationDuring the winter months, battery capacity tends
to decrease as temperatures drop. Additionally,
more power is consumed while starting, and the
headlights, heater, rear window defogger, etc.,
are used more frequently.
Let your Porsche dealer test the battery's capaci-
ty before winter sets in.Vehicle storageIf the car stands for long periods in the garage or
workshop, the doors and lids should be closed.
fRemove the ignition key and, if necessary, dis-
connect the battery.
Notes on operation
fWhen the battery is disconnected, the alarm
system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
fLock the vehicle and unlock it again.Maintenance note
Even if you put your vehicle out of operation, the
battery still discharges.
The battery will discharge more quickly if your ve-
hicle is not driven on a daily basis over a distance
of several miles. The more often you drive your ve-
hicle, and the longer the distance driven on each
trip, the more opportunity the vehicle‘s charging
system will have to recharge the batteries.
fTo preserve its efficiency, charge the battery
about every 6 weeks.
fCheck the battery acid level and top off with
distilled water if necessary.
fStore a battery that has been removed in a
dark, cool place, but not subject to freezing.
Putting vehicle into operationAfter the battery is connected or charged, the
PSM warning light lights up on the instrument pan-
el 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 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.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
5. Perform adaptation of the power windows:
Please observe the chapter “STORING FINAL
POSITION OF THE DOOR WINDOWS” on
Page 35.
6. On vehicles with tire pressure monitoring:
Please observe the chapter “SYSTEM LEAR-
NING PHASE” on Page 104.

Charging the batteryYour authorized Porsche dealer will be pleased to
advise you about a suitable charger.
1. Always observe the instructions of the charger
manufacturer.
2. When charging the battery, ensure adequate
ventilation.
3. Check the acid level of a low-maintenance bat-
tery.
4. Connect charger to the jump starting points.
Only plug into the mains and switch the charg-
er on when it has been correctly connected up.
5. After charging, disconnect the charger.
6. Check the acid level of a low-maintenance bat-
tery.
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 mes-
sage 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-pur-
pose display of the instrument panel.
