Malfunction indication

The malfunctions indicated may be
due to two causes:
– Gearbox failure
– Gearbox oil temperature too high
In both cases, the warning light
illuminates.
Gearbox failure
A gearbox failure is indicated on the
display by the message "Check
transmission go to dealer". While
driving, the ECU that controls the
device sets an emergency program.
WARNING: In these conditions, we
5
recommended that you stop the
vehicle and turn off the engine for at
least one minute. When restarting the
engine, the autodiagnostic system may
cancel the malfunction, which will in
any case be recorded by the ECU.
In failure conditions, the gearshift
lever A can still be shifted to positions
R, N and D.
160
Electronic automatic gearbox
When shifting to D, only a few gears
will be available for shifting,
depending on the malfunction found.
WARNING: If a gearbox failure is
signaled, take your vehicle to the
nearest Authorized Maserati Dealer as
soon as possible to have the problem
corrected.
If the failure is signaled when the
engine is started, it means that the
gearbox ECU detected a fault when
the vehicle was last used. Also in this
case, take your vehicle to the nearest
Authorized Maserati Dealer to have
the gearbox checked.
When the gearbox is
malfunctioning, drive very
carefully considering that
vehicle performance is reduced. In
addition, the reverse gear safety lock
may not be active: absolutely do not
shift the lever to R when the vehicle is
moving.
Gearbox oil temperature too high
This message is displayed when the
gearbox oil has reached the maximum
temperature. In this case, the gearbox
ECU sets an emergency program.
WARNING: We recommend that you
always stop the vehicle, shift the lever
to position P or N and keep the engine
idle until the temperature warning
light goes off and the message
disappears from the display. Resume
driving without demanding high
engine performance.
If the warning light illuminates again
and the message is displayed again,
stop the vehicle again and run the
engine at idle speed until the light
goes off and the message disappears.
If the interval between the two
warnings is less than 15 minutes, it is
advisable to stop the vehicle, turn off
the engine and wait for the engine/
gearbox assembly to fully cool down.
