Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
f In order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter), have the fault diagnosed and
rectified immediately at the nearest authorized
Porsche dealer. If the warning light in the
instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was running.
f Stop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your au-
thorized Porsche dealer for service as soon as
possible.
Caution!
If the check engine warning light in the in-
strument panel is flashing, serious catalytic
converter damage and power loss will soon
occur.
Prolonged driving with the check engine war-
ning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
f Have the fault remedied at the nearest authorized Porsche dealer immediately.

If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level checked at every fuel filling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if en-
gine rpm is above idle speed.Engine Oil Level f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 186.
f Regularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 161.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.3 quarts (1.25 liters).
Each segment of the display corresponds to ap-
prox. 0.42 quart (0.4 liter).
Topping off engine oil
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
f Keep engine oil out of children’s reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
f Always protect your skin by washing thorough-ly with soap and water. Caution!
Risk of damage from overflowing engine oil.
f Take care while checking and topping up
engine oil not to soil the luggage compartment or items of luggage.

Vehicle interior
The interior must be dry, especially in the area of
the floor carpets. The use of drying agents (Silica-
Gel) is recommended in vehicles with leather inte-
rior and in areas with high humidity. The recom-
mended amount is 3 fabric bags of 1.1 lbs.
(500 grams) each placed on the floor carpets.
Windows, doors and lids must be closed. The air
vents should be opened.

Practical Tips, Emergency Service
241
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.
f Have 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 batt ery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is co nnected 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.
f Perform adaptation of the power windows:
