2002 Infiniti QX: Cruise control designed to maintain a set distance from other traffic was the main addition for 2002. The QX4 shared Nissan's Intelligent Cruise Control with Infiniti's flagship Q45 sedan. Employing laser sensors, the system was designed to automatically speed or slow the QX4 to keep it a constant distance from cars ahead. Also new for 2002 was a revised audio system, plus audio controls for the available leather/wood steering wheel. The optional rear-seat video entertainment system offered a choice of VCR or DVD player.
