PRECAUTIONS FOR KEY REGISTRATION

• The key registration is a procedure that erases the current IVIS (NATS) ID once, and then re-registers a new

ID operation. Therefore the registered Intelligent Key is necessary for this procedure. Before starting the reg-
istration operation collect all registered Intelligent Keys from the customer

• When registering the Intelligent Key, performs only one procedure to register simultaneously both ID (IVIS

“NATS” ID registration and Intelligent Key ID registration).
The IVIS (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 IVIS (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 IVIS (NATS).
• The security indicator always blinks when the ignition switch is in LOCK and ACC position.
NOTE:
Because security indicator is highly efficient, the battery is barely affected.
