suit your individual requirements (4 - 120 sec-
onds).
Ty p e 2
The doors stay locked when the luggage compart-
ments are unlocked.
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
hazard warning lights.
If this should occur:
fLock the vehicle with the key in the door.The remote-control standby function
switches off after 7 days If the vehicle is not started or unlocked with the re-
mote control within five days, the remote control
standby function is switched off (to prevent dis-
charging of the car battery).

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.

Controls, Instruments If the battery voltage drops abruptly, a warning
m e s s a g e w i l l b e d i s p l a y e d b y t h e o n - b o a rd c o m p u -
ter.
If the warning is displayed by the on-board
computer while the engine is running or while
driving:
fStop the car in a safe place and stop the
engine.
Possible causes
– Defect in the battery charging system.
– Broken drive belt. Warning!
Risk of an accident and risk of engine dam-
age.
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.
fDo not continue driving.
fHave the fault remedied at the nearest author-ized Porsche dealer. The warning light in the instrument panel comes
on when the ignition is first turned on and remains
on briefly as a bulb check. If the light does not
come on, have the bulb replaced promptly.
If the warning lights in the instrument panel and on-
board computer come on and remain on while
driving, it suggests:
– a potential engine control problem and the
need for system service or
– an improperly fastened tank cap or
– refueling with engine running.
Although the vehicle is usually driveable and will
not require towing, see your dealer for service as
soon as possible.
Caution!
If the Check engine light in the instrument
panel is flashing, severe catalytic converter
damage and power loss will soon occur.
Prolonged driving with the Check engine light
on could cause damage to the emission con-
trol system. It also could affect fuel economy
and driveability.
fHave the fault remedied at the nearest author-ized Porsche dealer immediately.

Practical Tips, Emergency Service
Charge stateA well-charged battery prevents starting problems
and has a longer useful life.
Traffic density, speed limits, requirements
regarding noise, exhaust gas and fuel consump-
tion reduce the engine speed and, hence, the
generator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid unintended battery
discharge
fSwitch off unnecessary electrical loads in city
traffic, on short trips and in queues.
fAlways withdraw the ignition key when leaving
the vehicle.
fAvoid frequent operation of the Porsche
Communication Management system when the
engine is not running.
Battery carefKeep battery surface clean and dry.
fEnsure that cell plugs and terminal clamps are
firmly secured.
Checking acid level
The acid level should be more frequently checked
by a qualified specialist workshop during the
summer months and in predominantly warm
countries.
Charging the battery
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. Extremely
important: disconnect the negative cable first,
and then the positive cable – danger of short
circuit!
Reconnection must be carried out in reverse
order.
2. Before charging, cold batteries must be
warmed up indoors.
3. Frozen batteries must not be charged. They
must be replaced with a new battery.
4. When charging, ensure adequate ventilation. 5. Connect charger to the battery.
Only plug into the mains and switch the
charger on when it has been correctly
connected up.
Warning!
Hydrogen gas generated by the battery
could cause an explosion, resulting in severe
personal injuries.
fCharge battery in a well ventilated area.
fNever charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
fIf 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.
