An Important Word of Caution
on the Emission Control System
in Your Car
Y o u r car is equipped w i t h an Emission C o n -
trol S y s t e m . The major components of this
system are catalytic converter, secondary air
injection, and EGR (Exhaust Gas Recircula-
tion).
These components are designed to burn
carbon monoxide and hydrocarbons in the
exhaust gas. Normal operating temperature
of the exhaust system will not cause any
heat related problems if you maintain and
use your vehicle properly.
However, lack of proper maintenance, mal-
adjustment of the fuel system or ignition
timing, as well as improper use of the v e -
hicle may cause the exhaust system to ex-
ceed its normal operating temperature.
Overheating may result in severe damage to
the catalytic converter, and under certain
conditions may also damage other c o m -
ponents of your car.
Therefore:
• Have your car maintained p r o p e r l y in
accordance with the service recommen-
dations of the W a r r a n t y & Maintenance
booklet.
• Do not alter or remove any c o m p o n e n t of
the Emission Control System unless ap-
p r o v e d by the manufacturer.
• Do not alter or remove any device, such
as heat shields, switches, valves, which
are designed to protect your car and the
environment against high exhaust system
temperatures.
• Do not continue to operate your vehicle if
you detect engine misfire or other unusual
operating c o n d i t i o n s .
• Do not park your car over combustible
material, including grass or leaves, which
may c o m e into contact w i t h the hot ex-
haust s y s t e m .
Catalytic Converter
Immediate damage to the catalytic converter
will result if you turn the ignition off w h i l e
your car is moving, or if you try to p u s h -
start the car, because under these c o n d i -
tions unburned fuel can reach the catalytic
converter.
Undercoating
If additional undercoating is used, it must
not be applied in the areas of the exhaust
manifold, exhaust pipes or heat shields.
During driving the substance used for
undercoating could overheat and cause a
f i r e .
Emission Control System
In the interest of clean air
Pollution of our environment is of increasing
c o n c e r n to all of us. We urge you to join us
in our efforts f o r cleaner air in controlling
the pollutants emitted from the automobile.
Porsche has long recognized its responsi-
bilities not only t o w a r d its customers but
also t o w a r d the public in general. We have
developed an emission control system that
controls or reduces those parts of the emis-
sion that can be harmful to our environment.
Your Porsche is equipped w i t h such a sys-
t e m . On the f o l l o w i n g pages we explain how
the Porsche emission c o n t r o l system w o r k s ,
and what you can do to keep it in w o r k i n g
order.
Y o u r new car is warranted under the terms
and conditions set forth in the W a r r a n t y &
Maintenance booklet.
Y o u , as the owner of the vehicle, have the
responsibility to provide regular maintenance
service for the vehicle and to keep a record
of all maintenance w o r k performed. To facil-
itate record keeping, have the service per-
formed by authorized Porsche dealers. They
have Porsche trained mechanics and special
tools to provide fast, efficient service.
