Emission control devices

Even if the vehicle is fitted with air
quality devices, the environment
deserves the utmost respect from every
one of us.
By following a few simple rules, the
driver can avoid damaging the
environment and very often can
reduce fuel consumption as well.
In this regard, some useful information
is listed here below; please read the
following carefully.
The correct operation of the air quality
devices not only helps to ensure
respect for the environment, but also
affects vehicle efficiency.
Keeping these devices in good
working conditions is the first rule for
driving both ecologically sound and
economically.
The first precaution is to follow the
Maintenace Schedule precisely.
Always use unleaded fuel.
If starting is difficult, do not make
prolonged attempts.
Especially avoid push starts, towing or
hill starts: these are all maneuvers that
can damage the catalytic converters.
For any emergency starting, only use
an auxiliary battery.
When driving, if the engine starts
"running poorly", continue driving,
but reduce the engine performance
required to a minimum and contact
your local Authorized Maserati Dealer
as soon as possible.
Never run the engine, even if only for
testing, with one or more spark plugs
disconnected.
Do not warm up the engine making it
idle before starting off, apart from
when the external temperature is very
low and, even then, for no longer than
30 seconds.
During normal operation, the
catalytic converter generates
high temperatures. Do not,
therefore, park the vehicle on
flammable materials (grass, dry
leaves, pine needles, etc.): risk of fire.
Do not install heat guards and do not
remove those already fitted to the
catalytic converter and to the exhaust
manifold.
Do not spray anything on the catalytic
converter, oxygen sensor and exhaust
manifold.
In addition to specific catalytic and pre-
catalytic converters, the vehicles are
equipped with a system for controlling
fuel vapor emissions. This system,
called ORVR, has been designed to
help reduce atmospheric pollution by
the evaporation from the fuel system.
Also, specific to these vehicles is the
fuel filler neck which comes equipped
with a sealed plug that is grounded to
avoid possible sparking during re-
fueling. These devices allow the
vehicle to be classified in the LEV. 1
homologation category.
Failure to comply with these
rules can originate fire
hazards.
Engine exhaust, some of its
constituents, and certain
vehicle components contain
or emit chemicals known to the State
of California to cause cancer and birth
defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of
component wear contain or emit
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
