Despite strong sales in 2002, the EXT gets a host of new upgrades for 2003 to help maintain its momentum. An improved StabiliTrak stability control system is now standard along with an upgraded braking system, High Intensity Discharge (HID) headlights, exterior mirrors with integrated turn signals and chrome wheels as an option. The interior also has a number of improvements, including tri-zone climate control, satellite steering wheel controls and a redesigned instrument cluster and center console. The standard Bose audio system receives some minor upgrades while new options include XM Satellite Radio, a DVD entertainment system and bucket seats for the second row. Added safety comes in the way of dual-stage airbags, adjustable pedals, a front-passenger seat sensor and three-point belts for all first- and second-row passengers.
