There are 4 places that Nissan recommends for jacking points:
1) Front suspension cross-member.
2) Rear suspension cross-member.
3) Pinch weld below the front door.
4) Pinch weld below the rear door.
Personally, I use the suspension cross member as a jack point then place jack stands under pinch weld locations. This allows me to jack up the entire front/rear of the car and change the tires on each side at once.
NOTE: NEVER rely solely on the jack to support the car. Use jack stands for safety!
