Emission Control System
In the Interest of Clean Air
Pollution of our environment has become a
problem that is of increasing concern to all of
us. We urge you to join us in our efforts for
cleaner air in controlling the pollutants emitted
from the automobile.
Porsche has developed an emission control
system that controls or reduces those parts of
the emission that can be harmful to our en-
vironment.Your Porsche is equipped with such
a system.
Porsche warrants the Emission Control Sys-
tem in your new car under the terms and con-
ditions set forth in the Warranty & Mainte-
nance booklet.
You, 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 work performed. To facilitate
record keeping, have the service performed
by authorized Porsche dealers. They have
Porsche trained mechanics and special tools
to provide fast, efficient service.

WARNING
To assure efficient operation of the Emis-
sion Control System:
• Have your vehicle maintained properly
and in accordance with the recommen-
dations described in your Warranty &
Maintenance booklet. Lack of proper
maintenance, as well as improper use
of the vehicle, will impair the function of
the emission control system and could
lead to damage.
• Do not alter or remove any component
of the emission control system unless
approved by the manufacturer.
• Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, etc., which are designed to pro-
tect your vehicle's emission control
system.
• Do not continue to operate your vehicle
if you detect engine misfire or other un-
usual operating conditions.
Starting
• Do not leave vehicle engine idling un-
attended after starting. If warning lights
should come on to indicate improper
operation, they would go unheeded. Ex-
tended idling also produces heat, which
could result in overheating or other da-
mage to the vehicle or other property.
Parking
• As with any vehicle, do not park or oper-
ate your vehicle in areas where com-
bustible materials, such as dry grass or
leaves, can come into contact with a hot
exhaust system.
Undercoating
• Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con-
verter or heat shields. During driving the
substance used for undercoating could
overheat and cause a fire.
