The second generation also saw the introduction of "Super Select" 4WD (SS4) as ActivTrak 4WD in some markets, Multi-Mode ABS and electronic shock absorbers which were firsts on Japanese four-wheel drives. SS4 was ground-breaking in the sense that it combined the advantages of part-time and full-time four-wheel drive with four available options: 2H (high-range rear-wheel drive), 4H (high-range full-time four-wheel drive), 4HLc (high-range four-wheel drive with locked centre differential) and 4LLc (low-range four-wheel drive with locked centre differential). Another advantage of this second generation system is that it gave the driver the ability to switch between two-wheel drive and full-time four-wheel drive at speeds up to 80 km/h (49 mph), whereas the first generation Pajero which used a traditional 4WD system had to be stationary to switch from rear-wheel drive to four-wheel drive (but not from four-wheel drive back to rear-wheel drive). In addition to the SS4, a pneumatic locking differential was included as a factory option. The transfer case is required to be in 4HLc or 4LLc to engage the rear locking differential. Multi-mode ABS, on the other hand, was equally innovative. This meant ABS would be fully functional in all modes of SS4, as braking with a locked centre differential requires completely different braking parameters. The new electronic shock absorber was also factory option with three settings: S (soft), M (medium), and H (hard). This meant driver can change ride quality and handling depending on road conditions via a switch on centre console.
