instruments and a trip computer) and an optional power sunroof (sunroof was standard on Maxima wagons). 15-inch alloy wheels were standard for the Maxima. An exclusive option for 1988 was the Sonar Suspension System -which was part of the Electronics Pkg- replacing the trip computer that was previously offered. This feature used sonar waves to monitor the road conditions ahead and adjusted the shocks accordingly for the most controlled ride. 1988 was also the year that the previously standard digital touch system offered on the GXE sedan became part of the 'Electronics Package' option as well. The SE (and some GXEs) offered dual power seats, a five-speed manual transmission, three-way shock adjustable suspension, front and rear windshield defroster, and a factory-installed security system. The SE also has a small rear spoiler, all-wheel disc brakes, black side rear view mirrors, and body molding (GXE got body-color side rear-view mirrors and matching body molding).

The Maxima provided a combination of luxury and sporty features while the Cressida was generally seen as being softer and more luxurious.

Third generation (J30; 1988) The redesigned Maxima debuted on October 24, 1988 for the 1989 model year, internally designated J30. Larger dimensions made it the second Japanese sedan sold in North America to qualify as a "mid-size" (after the Mazda 929). Nissan used a "4DSC" window decal on the third generation Maxima in North America, marketing it as a "four-door sports car." This generation was briefly marketed in Japan, replacing the Nissan Leopard sedan at Nissan Bluebird Store locations. A refresh occurred in August 1991 for the 1992 model year (from July 1991 production), adding a driver's side SRS airbag. The facelifted version was no longer offered in Japan. It now featured the , 3.0-liter VG30E V6, with the , VE30DE unit standard on the SE model starting in 1991. In the United States, the VG30E engine, which featured a variable intake manifold on automatic and manual transmission
