The warning light in the speedometer lights up:
– When a loss in pressure has been detected
– If the tire pressure monitoring is faulty
– When learning newly mounted wheels/wheel
sensors, as long as the vehicle’s own wheels
have not yet been recognized.
The tire pressure warning light in the instrument
panel goes out only when the cause of the fault
has been rectified.
No monitoringIn the event of faults the tire pressure monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel lights up
and a corresponding message appears on the
on-board computer.
Monitoring is not active when:
– the tire pressure monitoring is faulty,
– wheel transmitters for the tire pressure
monitoring are missing,
– temporarily after changing a wheel (learning
phase),
– more than four wheel transmitters are
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.

How Emission Control Works When an automobile engine is running, it uses en-
ergy generated through the combustion of a mix-
ture of air and fuel. Depending on whether a car is
driven fast or slowly or whether the engine is cold
or hot, some of the fuel (hydrocarbons) may not
be burned completely, but may be discharged into
the engine crankcase or exhaust system. Addito-
nal hydrocarbons may enter the atmosphere th-
rough evaporation of fuel from the fuel tank. These
hydrocarbons (HC), when released into the air,
contribute to undesirable pollution.
In addition, carbon monoxide (CO) and oxides of
nitrogen (NOx) contribute to engine emissions.
They, too, are formed during the combustion pro-
cess and discharged into the exhaust system.
To reduce these pollutants, your Porsche is equip-
ped with a precisely calibrated fuel injection sys-
tem to assure a finely balanced air/fuel mixture un-
der all operating conditions.
Oxygen sensor The oxygen sensor, installed in the exhaust pipe
continuously senses the oxygen content of the ex-
haust and signals the information to an electronic
control unit. The control unit corrects the air/fuel
ratio, so the engine always receives an accurately
metered air/fuel mixture. Crankcase ventilation Through crankcase ventilation, undesirable emis-
sions from the engine crankcase are not permit-
ted to reach the outside atmosphere. These emis-
sions are recirculated from the crankcase to the
air intake system. From here the emissions mix
with the intake air and are later burned in the engi-
ne. Catalytic converters The catalytic converters are efficient ”clean-up“
devices built into the exhaust system of the vehic-
le. The catalytic converters burn the undesirable
pollutants in the exhaust gas before it is released
into the atmosphere.
The exclusive use of unleaded fuel is critical-
ly important for the life of the catalytic con-
verters. Therefore, only unleaded fuel must
be used. The catalytic converters will be damaged by:
– push or tow starting the vehicle,
– misfiring of the engine,
– turning off the ignition while the vehicle is mo-
ving or
– driving until the fuel tank is completely empty,
– by other unusual operating conditions.
fDo not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law pro-
hibits use of leaded fuel in this car.

Maintenance, Car Care Automatic car washes
Optional add-on parts or parts which project
beyond the contours of the vehicle may be
damaged by design features (e.g. brushes) of au-
tomatic car washes.
The following parts are particularly suscep-
tible to damage:
– Convertible top (hot wax treatment cannot be
used, as the wax attacks the convertible top
material),
– Windshield wipers (always switch them off to
prevent them wiping unintentionally in intermit-
tent or sensor operation)
– External telephone antenna (always unscrew)
– Fixed rear spoiler or extended rear spoiler
– Wheels (the wider the rim and the lower the tire
height, the greater the risk of damage)
– High-gloss wheels (to prevent these from get-
ting scratched, do not clean with the wheel-
cleaning brushes of the car wash).
fPlease consult the operator before using auto-
matic car washes.
fWash and dry by hand all points not reached by
a car wash, such as door and lid seams or
door sills. Note
Automatic car washes spray water at odd angles
and high pressures, which are not seen in normal
driving. Therefore, water can sometimes find its
way into the passengers compartment during or
shortly after the car wash.
Door locks fTo prevent the door locks from freezing during
the cold season, the lock cylinders should be
covered during a wash.
fShould the locks freeze, use an ordinary de-
icer. In many cases, a well warmed key can
help.
Never use excessive force.
