Maintenance and Care
On Board Diagnostic System —
OBD II
This vehicle is equipped with a
sophisticated onboard diagnostic
system called OBD II. This system
monitors the performance of the
emissions, engine, and automatic
transmission control systems. When
these systems are operating properly,
your vehicle will provide excellent
performance and fuel economy, as
well as engine emissions suited to
current government regulations.
If any of these systems require service,
the OBD II system will turn on the
"Malfunction Indicator Light"
the instrument cluster display (refer to
"Instrument Cluster" in section 4). The
system stores as well diagnostic codes
and other information to assist your
service technician by performing
repairs.
Although the vehicle will be drivable
and will not need towing, contact an
Authorized Maserati Dealer for service
as soon as possible.
