PRECAUTIONS FOR KEY REGISTRATION

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

Therefore the registered key is necessary for this procedure. Before starting the registration operation collect

all registered Keys from the customer.

• The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in

mechanical key) to BCM.

The key ID registration is the procedure that registers the ID to the BCM.

• When performing the key system registration only, the engine cannot be started by inserting the key into the

key cylinder. When performing the NATS registration only, the engine cannot be started by using the ignition

key.

SECURITY INDICATOR

• Always flashes with ignition key in the OFF position.

The vehicle security system turns into the pre-armed phase when ignition switch is in OFF position, all doors

are closed and locked (using keyfob, door lock/unlock switch, driver key cylinder or auto relock function). The

system automatically shifts into the armed phase.

Condition of Activating The System

When the following condition is performed in armed phase, the system sounds the horns and flashes the

headlamps for approximately 50 seconds.
