StabiliTrak, an integrated chassis control system that can prevent four-wheel lateral skids, is available on base and d'Elegance. New radio systems debut, and door lock programmability is enhanced. An idiot light is added to warn about loose fuel caps, and new colors are available inside and out. Heated seats are added to the d'Elegance and Concours while the Concours also gets a much needed alloy wheel redesign. Second-generation airbags debut as standard equipment.
