SYSTEM DESCRIPTION
PRECAUTIONS FOR KEY REGISTRATION
- The key registration is a procedure that erases the current NVIS
(NATS) ID once, and then re-registers a
new ID operation. Therefore, the registered Intelligent Key is necessary for
this procedure. Before starting
the registration operation collect all registered Intelligent Keys from the
customer
- When registering the Intelligent Key, perform only one procedure
to register simultaneously both ID (NVIS
"NATS" ID registration and Intelligent Key ID registration).
The NVIS (NATS) ID registration is the procedure that registers the ID
stored into the transponder (integrated
in Intelligent Key) to BCM.
The Intelligent Key ID registration is the procedure that registers the ID
to BCM.
- When performing the Intelligent Key system registration only, the
engine cannot be started by inserting the
key into the key slot. When performing the NVIS (NATS) registration only,
the engine cannot be started by
the operation when carrying the key. The registrations of both systems
should be performed.
SECURITY INDICATOR
- Warns that the vehicle is equipped with NVIS (NATS).
- The security indicator always blinks when the Intelligent Key is
removed from the key slot and when the ignition
switch is in LOCK position.
NOTE:
Because security indicator is highly efficient, the battery is
barely affected.
