Ensure proper operation of different
devices checking their respective
control tell tales.
CAUTION!
• Under normal conditions, all red
warning light on the instrument
cluster display should be off. When
they come on, they indicate a
malfunction. Refer to "Instrument
Cluster" in section 4.
• Continuing to drive when a red
warning light is on could cause
serious damage to the vehicle and
affect its performance.
WARNING!
Do not travel downhill with the
engine off, as the servo brake will no
longer function due to the vacuum
decrease and thus after a few braking
attempts, the system becomes totally
inefficient. The power steering will
also lose its efficiency under these
conditions.
On Board Diagnostic System
Your vehicle is equipped with a
sophisticated onboard diagnostic
system called EOBD. 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 well within
current local regulations of various
countries.
If any of these systems require service,
the EOBD system will turn on the
malfunction indicator light (MIL).
It will also store diagnostic codes and
other information to assist which your
Maserati Service Center will use to
service your vehicle. Although the
vehicle will still be drivable and not
need towing, contact the Maserati
Service Network for service as soon as
possible.
CAUTION!
• Prolonged driving with the
malfunction indicator light (MIL)
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
