Anti-Theft Alarm Systems - Maserati GranTurismo Owner's Manual

Understanding the Vehicle
• stabilize the vehicle when the
accelerator pedal is released by locking
the rear axle;
• control vehicle dynamics by locking the
differential proportionally in relation to
2
lateral acceleration and vehicle speed;
• maximize both vehicle stability and
acceleration when cornering by locking
the differential proportionally in relation
to lateral acceleration, speed, selected
gear and torque produced by the
engine.
To obtain these results, the LSD system
interacts with the ESC and ABS systems,
automatic transmission and suspension
damping control.

Anti-theft Alarm Systems

Engine Immobilizer System
The Immobilizer System (Sentry Key
prevents unauthorised vehicle operation
by disabling the engine. The system
does not need to be armed or activated.
Operation is automatic, regardless
of whether the vehicle is locked or
unlocked.
The system uses a key fob with Remote
Keyless Entry (RKE) transmitter,
an ignition device and a RF (Radio
Frequency) receiver to prevent
unauthorised vehicle operation.
Therefore, only key fobs expressly
programmed can be used to start and
operate the vehicle.
NOTE:
• Technical changes to the vehicle
unannounced by the manufacturer may
render the information in this manual
unusable.
• Any modification or alteration applied
to the VAS-Immo system could impair
on the vehicle safety and could
invalidate the type approval.
When the ignition device is set to ON
position, Engine Immobilizer system
identifies the code transmitted by the
key fob. If the code is recognized as
valid, the Engine Immobilizer system
enables engine starting.
When the ignition device is brought back
to STOP position, the Engine Immobilizer
system deactivates the control module

)
controlling the engine, thus preventing
its starting.
If, during starting, the key code is
not correctly recognized, the
warning light is displayed on the
instrument cluster (see "Warning and
Indicator Lights" in section "Dashboard
Instruments and Controls").
This condition leads to the engine
switching off after 2 seconds. In this
case, bring the ignition device to STOP
and then to ON.
If it is still not possible to start the
engine, contact the Service Network.
If the warning light is displayed
while driving, this means that the system
is running a self-diagnosis (e.g. due to
a voltage drop). If the display persists,
contact the Service Network.
CAUTION!
• Do not tamper with the Engine
Immobilizer system. Any
modifications/alterations could
cause the protection function to be
deactivated.
• The Engine Immobilizer system is
not compatible with some remote
