Infinity Vehicle Immobilizer System - NATS (IVIS)

Observe the precautions to ensure safe and proper servicing.

PRECAUTIONS FOR IVIS (INFINITI VEHICLE IMMOBILIZER SYSTEM - NATS)
IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of IVIS (NATS).

Both of the originally supplied ignition key IDs have been IVIS (NATS) registered.

The security indicator is located on the instrument panel. The indicator blinks when the ignition switch is in "OFF" or "ACC" position. Therefore, IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

When IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition switch is in "ON" position. This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

When servicing IVIS (NATS) (trouble diagnoses, system initialization and additional registration of other IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II IVIS (NATS) software is necessary.

Regarding the procedures of IVIS (NATS) initialization and IVIS (NATS) ignition key ID registration, refer to CONSULT-II operation manual, IVIS (NATS).

Therefore, CONSULT-II IVIS (NATS) software (program card and operation manual) must be kept strictly confidential to maintain the integrity of the anti-theft function.

When servicing IVIS (NATS) (trouble diagnoses, system initialization and additional registration of other IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to receive all keys from vehicle owner. A maximum of five key IDs can be registered into IVIS (NATS).

When failing to start the engine first time using the key of IVIS (NATS) (for example, when interference is caused by another IVIS (NATS) key, an automated full road device or automated payment device on the key ring), restart as follows.
a. Leave the ignition switch in ON position for approximately 5 seconds.
b. Turn ignition switch to OFF or LOCK position and wait approximately 5 seconds.
c. Repeat step 1 and 2.
d. Restart the engine while holding the device (which may have caused the interference) separate from the registered NATS key. If the no start condition re-occurs, NISSAN recommends placing the registered IVIS (NATS) key on a separate key ring to avoid interference from other devices.
