Precautions For Intelligent Key System
WARNING: This page is about a different car, the 2011 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
- The transponder [the chip for NVIS (NATS) ID verification] is integrated into the Intelligent Key. (For the conventional models, it is integrated into the mechanical key.) Therefore, ID verification cannot be performed by mechanical key only. In that case, the NVIS (NATS) ID verification can be performed when Intelligent Key is inserted into key slot. If verification result is OK, engine can be started.
