Winter operation The capacity and ability of the battery to store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in
winter months, e.g. by the heated rear window,
more frequent use of additional lights, the fans
and the windshield wipers, etc.
fHave the battery checked before the start of
winter.
Maintenance note
Keep the battery well charged to prevent it
from freezing.
A discharged battery can freeze at 23 °F (--5 °C),
but a fully charged battery only freezes at -- 40 °F
(--40 °C).
A frozen battery must always be thawed before
connecting jump leads.
Replacing battery The service life of the battery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
fOnly use an original Porsche battery, with the
correct part number, as a replacement.
fPlease observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
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 multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
fPerform adaptation of the power windows:
Please see the chapter “STORING END
POSITION OF THE WINDOWS” on Page 26.

Practical Tips, Emergency Service
Removing the battery The required tool is in the tool kit.
The battery is located in the luggage compart-
ment under a black plastic lid.
Warning!
Risk of damage to alternator and electronic
control units.
fDo not disconnect the battery while the engine
is running.
This also applies to cars equipped with a bat-
tery main switch.
fNever drive the car with a disconnected bat-
tery.
Risk of caustic burns from escaping acid.
fKeep vent caps on to avoid spillage.
fDo not tilt the battery when removing and in-stalling it. 1. Switch off engine and all electrical loads.
2. Open turn-locks A.
Remove plastic lid.
3. Pull off central vent hose C.
Danger!
Risk of short circuit and explosion, resulting
in serious personal injury or death.
fImportant: disconnect the negative (–) ground wire first, and then the positive (+) cable.4. Important: disconnect the negative (–) ground
wire first, and then the positive (+) cable -
danger of short circuit!
5. Unscrew fastening screw B.
6. Remove battery.

Installing the battery 1. Put battery in and push it all the way to the
stop.
2. Screw in fastening screw B.
Danger!
Risk of short circuit and explosion, resulting
in serious personal injury or death.
fImportant: connect the positive (+) cable first, and then the negative (–) ground wire.
3. Important: connect the positive (+) cable first,
and then the negative (–) ground wire -
danger of short circuit!
4. Push on central vent hose C.
Fitting the plastic lid
1. Insert the two outer hooks of the plastic lid into
the eye mounts of the lid opening.
2. Lower the lid.
3. Using both hands, push the lid into the eye
mounts without using force (if too much force
is used, the hooks may jam and the panel will
warp).
Make sure that the lid is correctly seated.4. Turn the turn-locks so that they point in
longitudinal direction.
5. Press the turn-locks down until they audibly
engage.

Practical Tips, Emergency Service
Replacing the remote-control
battery The battery should be changed when the range of
the radio remote control becomes smaller or
when the light-emitting diode no longer flashes
when the remote control is operated.
1. Using your finger nail or a small screwdriver,
carefully lift off the cover of the key grip
(arrow).
2. Replace the battery (paying attention to the
polarity).
Replacement battery – Lithium CR 2032,
3volts.3. Replace the cover and press together firmly.
Please observe the disposal instructions for
batteries.
Note
fPlease dispose batteries in compliance with
any and all government regulations.

Emergency Starting with Jumper
Cables If the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same. Both batteries must be 12 volt types.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.
The discharged battery must be correctly con-
nected to the vehicle’s electrical system.
fPlease see the chapter “BATTERY” on
Page 261.
fPlease see the chapter “EMERGENCY UNLO-
CKING OF THE LUGGAGE COMPARTMENT LID”
on Page 260.
Note
fDo not try to start the car by pushing or tow-
ing. Damage to the catalytic converters and
other components of the car may result.
Warning!
Risk of short circuit, damage and explosion,
resulting in serious personal injury or death.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fEnsure that tools or conductive jewelery (rings,
chains, watch straps) do not come into contact
with the positive jumper cable or the positive
battery post.
fImproper hook-up of jumper cables can ruin
the alternator. Danger of caustic burns from escaping acid.
fDo not lean over the battery.
Danger of gas explosion.
fImproper use of booster battery to start a
vehicle may cause an explosion, resulting in
serious personal injury or death.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at 23 °F/
–5 °C.
Before connecting jumper cables, a frozen
battery must be thawed out.

Practical Tips, Emergency Service
Connect jumper cables in the following
sequence: Always observe the sequence below:
1. Connect the positive lead (red) to the
positive terminal of the discharged battery
first, then connect it to the positive terminal of
the donor battery.
2. First connect the negative cable (black) to
the negative terminal of the donor battery, then
connect it to a suitable grounding point on the
vehicle with the discharged battery.
This grounding point must lie as far as possible
from the battery.
For example, a solid metal part or the engine
block are suitable grounding points.
If no suitable grounding points are to be found
on either vehicle, the negative cable must
carefully be connected directly to the negative
terminal of the battery.
If a suitable grounding point is to be found only
on the donor vehicle, the negative cable must
first be connected to the terminal of the
discharged battery, then to the grounding point
of the donor vehicle.
3. Run the engine of the donor car at a higher
speed.4. Start the engine.
An attempted start using jumper cables should
not last more than 15 seconds. Then allow a
waiting period of at least one minute.
fNote
Before disconnecting the jumper cables, elec-
trical loads such as the heated rear window
and the heating fan blower should be switched
on (the vehicle’s lights must not be switched
on). This reduces voltage peaks which may oc-
cur when disconnecting the jumper cables.
With the engine running, remove both jumper
cables in reverse order.

Caution!
Risk of damage to headlights due to exces-
sive temperatures and abrasion.
fTo ensure optimum ventilation, do not cover
the gap between headlight and body
(e.g. “stone guards” or films).
fUse soapy water only to clean light lenses and
plastic headlight lenses.
In no case may chemical cleaners or other vol-
atile cleaning fluids be used.
fTo prevent scratches, do not rub with a dry or merely moist cloth, tissue or insect sponges.
