Instruments, On-Board Computer, Warnings The oil pressure is controlled as required and
should be at least 3.5 bar at an engine speed of
5000 rpm.
The engine oil pressure varies depending on the
engine speed, engine load and engine tempera-
ture.If oil pressure drops abruptly and a message
is displayed on the on-board computer when
the engine is running on or when driving:
fStop immediately in a suitable place.
fSwitch off the engine.
fCheck whether there is an obvious oil leak on
or under the car.
fIf no oil leak can be detected: With the engine
idling, measure the oil level with the on-board
computer.
fPlease see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 153.
fPlease see the chapter “ENGINE OIL LEVEL”
on Page 208.
fAdd engine oil if necessary.
Caution!
Risk of engine damage.
fDo not continue driving if there is an obvious oil
leak.
fDo not continue driving if the warning lights
come on even though oil level is correct.
fHave the fault remedied at the nearest authorized Porsche dealer.If the battery voltage drops abruptly, a warning
message will be displayed by the on-board compu-
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 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.
fDo not continue driving.

Battery The battery is located in the luggage compart-
ment under a black plastic cover.
fPlease see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 76.
fPlease see the chapter “EMERGENCY UNLO-
CKING OF THE LUGGAGE COMPARTMENT LID”
on Page 260.
Warning!
Risk of short circuit, fire and damage to al-
ternerator and electronic control units, re-
sulting in serious personal injury or death.
fObserve all warning notes on the battery.
fDisconnect the negative terminal on the bat-
tery during all work on the electrical system.
fDo 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.
fDo not expose the battery to an open flame,
electrical spark or a lit cigarette.
fDo not wipe battery with a dry cloth.
Risk of serious personal injury or death and
damage to the fabric, metal or paint. fWear eye protection.
fDo not allow battery acid to come in contact
with your skin, eyes, fabric or painted
surfaces.
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.
fSpilled electrolyte must be rinsed off at once
with a solution of baking 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.
fAlways 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.
fDo not wipe the battery with a dry cloth.
fEliminate 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
power.
In order to avoid discharging the battery
unintentionally:
fSwitch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
fAlways remove the ignition key from the igni-
tion switch when leaving the car.
fAvoid frequent operation of the convertible top
and operation of the Porsche Communication
Management system when the engine is not
running.
fIn 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.
fKeep terminals and connections clean and
properly tightened.
Corrosion can be prevented by coating the ter-
minals and connections with petroleum jelly or
silicone spray.
fEnsure that vent caps are 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 loose 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.
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. 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.
