Malfunction of the remote controlThe remote control may not function correctly due
to local radio wave interference. The vehicle will
then not lock properly.
This can be identified by the missing locking
sound and the missing check-back signal of the
emergency flasher.
If this should occur:
f Lock the vehicle with the key in the door.
The remote-control standby function
switches off after 7 daysIf the vehicle is not started or unlocked with the re-
mote control within 7 days, the remote control
standby function is switched off (to prevent dis-
charging of the vehicle battery).
1. In this case, unlock the driver’s door with the
key at the door lock.
Leave the door closed in order to prevent the
alarm system from being triggered.
2. Press button 1 on the remote control.
The remote control is now activated again and
the alarm system is switched off.
Operational readiness of the remote
control interruptedEncoded data is transmitted to the vehicle each
time the wireless remote control is operated. If the
remote control is operated too often outside the
range of the vehicle, this can result in the central
locking system no longer responding.
In this case, the remote control and vehicle must
be synchronized.
Carrying out the synchronization
1. Unlock the driver's door with the key at the door lock.
2. Open driver’s door and insert the ignition key into the ignition lock within 10 seconds to
prevent the alarm system from being
triggered.
3. With the key inserted, press and hold button 1
on the remote control for approx. 5 seconds.
The synchronization is now complete.

ter.
If the warning is displayed by the on-board
computer while the engine is running or while
driving:
f
Stop the car in a safe place and stop the
engine.
Possible causes
– Defect in the battery charging system.
– Broken drive belt.
Warning!
Risk of engine damage with resultant loss of
control and accident, leading to serious per-
sonal injury or death.
A broken drive belt means there is no power
assistance to the steering (more effort is re-
quired to steer) and coolant pump function
will stop.
f Do not continue driving.

SAGES” on Page 136. The warning light on the instrument panel lights
up:
– if the handbrake is on,
– if the brake fluid level is low,
– if the brake pads have
reached the wear limit,
– if the brake circuit division is defective.
Additionally, a warning is displayed by the on-
board computer.

Battery The battery is located in the front luggage
compartment under a black plastic cover.
f Please see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 74.
f Please see the chapter “EMERGENCY UNLO-
CKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 248.
Warning!
Risk of short circuit, fire and damage to alternera-
tor and electronic control units, resulting in seri-
ous personal injury or death.
f Observe all warning notes on the battery.
f Disconnect the negative terminal on the bat-
tery during all work on the electrical system.
f Do not lay tools or other metal objects on the
battery as they could cause a short circuit
across the battery terminal.
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
f Do not expose the battery to an open flame,
electrical spark or a lit cigarette.
f Do not wipe battery with a dry cloth.
Risk of serious personal injury or death and
damage to the fabric, metal or paint. f
Wear eye protection.
f Do not allow battery acid to come in contact
with your skin, eyes, fabric or painted
surfaces.
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 doc-
tor.
f Spilled electrolyte must be rinsed off at once
with a solution of baki ng soda and water to
neutralize the acid.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
f Always protect your skin by washing thorough-
ly with soap and water.
Risk of explosion as a result of static charge,
resulting in serious personal injury or death.
f Do not wipe the battery with a dry cloth.
f Eliminate potential electrostatic charge by
touching the vehicle before touching the bat-
tery.
Charge state A well-charged battery prevents starting problems
and has a longer service life.
Traffic density, requirements regarding noise, ex-
haust gas and fuel consumption reduce the engine
speed and, hence, the alternator output.
However, the large number of electrical loads has
markedly increased the demand for electrical po-
wer.
In order to avoid discharging the battery
unintentionally:
f Switch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
f Always remove the ignition key from the igni-
tion switch when leaving the car.
f Avoid frequent operation of the convertible top
and operation of the Porsche Communication
Management system and audio system when
the engine is not running.
f In the cold season in particular or if the vehicle
is used primarily for short journeys, it may be
necessary to recharge the battery from time to
time.

Practical Tips, Emergency Service
Battery care fEnsure that battery is securely mounted.
f Keep terminals and connections clean and
properly tightened.
Corrosion can be prevented by coating the ter-
minals and connections with petroleum jelly or
silicone spray.
f Ensure that vent caps ar e securely tightened to
prevent spillage.
Checking the electrolyte fluid level
The acid level should be checked more frequently
by a qualified specialist workshop during the sum-
mer months and in predominantly warm countries. Battery charging
Automotive batteries lose their efficiency when
not in use.
The charge available in your battery can be meas-
ured with a battery hydrometer.
We recommend that the battery voltage be tested
by your authorized Porsche dealer who has the ap-
propriate 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.
Warning!
Hydrogen gas generated 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 fro-
zen battery to thaw out first.
f If you get electrolyte, wh ich is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-tor. Slow battery charging
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
1. Always observe the instructions of the charger
manufacturer.
Depending on the type of charger, the battery
may have to be disconnected.
In this case, always disconnect the negative
lead first, and then the positive lead – risk of
short circuit!
Reconnect the leads in reverse order.
2. Before charging, cold batteries must be warmed up indoors.
3. Frozen batteries must be thawed out first before being charged.
4. When charging, ensure that there is adequate ventilation.
5. Connect the charger to the battery. Only plug into the mains and switch the
charger on when it is connected up correctly.
6. Switch on the charger.
7. After charging, switch off the charger first and then disconnect it.
