After its debut as General Motors' high-end compact SUV last year, the GMC Envoy gets equipment upgrades for '99. A new mini-module for the driver airbag allows for steering wheel radio controls, and the turn signal stalk now incorporates a flash-to-pass headlamp feature. Heated, eight-way power front seating is improved, thanks to available two-position memory for the driver and power recliners. A liftgate ajar telltale resides in the instrument cluster, and the outside rearview mirrors have been redesigned, featuring electrochromic dimming and power-folding capability. GM's advanced AutoTrac active transfer case is now standard, while a new shift lever-mounted button selects a tow/haul mode to optimize transmission shift points. There are three new metallic exterior paint colors: Topaz Gold, Meadow Green and Indigo Blue.
