I am admiring a 2003 Supercharged in a mall parking lot, when my girlfirends says..."your's is better, this one doesn't even say Nissan on the front wheels it says Automatic."
Anyways, the reason there is no emblem is in the case you have a 4x4 with manual hubs, you'd have to get out of your car, stick your hand through the hub covers, switch the hubs from free to lock and then be able to engage into 4x4 mode. I guess Nissan decided to leave it as the standard set and let everyone know you have a 4x4 with automatic free-locking hubs.
