Though the Xterra was updated just last year, Nissan has made further changes for 2003. Mechanically, the V6 has received a slight increase in power, and a stability control system (Nissan's VDC) will be a new option. Also for 2003, Xterra XE V6 models come with standard 16-inch alloy wheels and tubular step rails, and four new exterior colors are available, including Atomic Orange and Camouflage (limited and late availability). Inside, a driver seat-height and lumbar adjuster has been added to V6 models and a new roof headliner net (on nonsunroof models) and luggage side net have also been added, along with new metal ceiling tie-down hooks. A "rugged" leather package is now offered for the SE trim. Other refinements include a 300-watt rating for the Rockford Fosgate-powered eight-speaker audio system, an available tire-pressure monitoring system and Electronic Brakeforce Distribution. A heavy-duty alternator and dual 12-volt power outlets located in the engine compartment are also standard on SE trim.
