The hybrid section of the manual does not mean much. It's likely just a standard template.
Nissan (Carlos Ghosn in particular) has be pretty opposed to going the hybrid route as they feel zero-emissions vehicles are the future and hybrids are just an interim measure. But the popularity of hybrids in the US forced them to market one of thier own. Nissan currently licenses thier Hybrid technology from Toyota. This is a temporary measure as Nissan has been developing but has not released thier own Hybrid system along with advanced fuel cell and battery technologies. At this point, I do not expect Toyota's hybrid technology to show up in other Nissan vehicles as the license is likely very limited in the numbers they can produce.
Now, I do expect Nissan to release thier own Hybrid and zero-emission technology very soon. Nissan recently unveiled it's new business plan GT2012:

Part of that plan is to introduce Nissan's original hybrid technology by 2010 along with zero-emissions electric vehicles. Nissan has also ramped up production with NEC to produce lighter more powerful Lithium-Ion batteries. The L-Ion batteries could make a hybrid system much lighter and more compact. Currently the system used on the Altimas (and Toyota's) uses heavy NiMh batteries.
The next few years are going to be a watershed for the automotive industry. While electric cars are nothing new, we will start to see them in numbers never seen before and it will mark the shift away from gasoline. Change will happen slowly, but it will happen.
Cheers!
