The Suburban received a substantial update for 2003, with more than 40 major changes designed to enhance safety and improve reliability. The StabiliTrak electronic stability program became available for improved control on slippery surfaces. New airbag systems were designed to better protect children and adults of various sizes. Adjustable pedals became available for the comfort and safety for drivers of smaller stature. The brakes were refined, and an all-new electrical architecture promised improved reliability. XM Satellite Radio became available, along with a new Panasonic DVD system for back-seat monkeys.
Changes for 2004 enhance safety further. New Hydroboost brakes provide power assist even if the engine stalls or is turned off. A tire-pressure monitor is now standard. New options include stand-alone traction control and 17-inch all-weather tires. There's also a new 7-to-4-pin wiring adapter for the trailer package.
Heavy-duty Suburban 2500-series models can be ordered with Quadrasteer electronic four-wheel steering for dramatically increased maneuverability in tight spaces and improved control when towing a trailer. Next Page
