Exterior

For 2006, a new front grille and tri-shield emblem are installed. Sculpted wheel flares and shoulders are meant to enhance the Rainier's appearance.

Clear headlights have offset high/low beam fixtures. Fog lamps with chrome surrounds are standard. Two-tone front and rear fascias are body-colored over gray, with the gray portion extending into the rocker panels. The Rainier features 17-inch wheels, power rack-and-pinion steering and Bilstein shock absorbers.
