Pollution Control Devices - Maserati GRANCABRIO Owner's Manual

Pollution control devices

Even if the vehicle is fi tted with anti-
pollution devices, the environment
deserves the greatest 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 it carefully.
The correct operation of the anti-
pollution devices not only helps
respect for the environment, but also
has an impact on vehicle effi ciency.

Keeping these devices in good
working conditions is the fi rst rule for
driving both ecologically sound and
economically.
The fi rst precaution is to follow the
Maintenance Schedule scrupulously.
Always use unleaded fuel.

If starting is diffi cult, do not make
prolonged attempts.
In particular, avoid push starts,
towing or downhill starts: these are
all manoeuvres that can damage the
catalytic muffl ers.
For any emergency starting, only use
an auxiliary battery.
While driving, if the engine does
not run smoothly, you may continue
driving but reducing engine
performance to a minimum; you
should then contact the Maserati
Service Network 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 letting it
idle before starting off, except in the
event that the external temperature
is very low and, even then, for no
longer than 30 seconds.
During normal operation
the catalytic converter
produces high temperatures.
Therefore, do not park the vehicle on
fl ammable materials (e.g. grass, dry
leaves, pine needles, etc.): risk of fi re!
Do not install heat guards and do not
remove those already fi tted to the
catalytic converter and to the exhaust
manifold.
Do not spray anything on the catalytic
converter, Oxygen sensor and exhaust
manifold.
Failure to comply with these
rules can create fi re hazards.
