It is an unfair or deceptive trade practice for a dealer to use initials or abbreviations in an advertisement of a motor vehicle, including the window sticker and supplementary sticker, unless all such initials or abbreviations are clearly defined in the advertisement or window sticker; provided, however, that abbreviations may be used for such options and features as air conditioning, power steering and power brakes in classified and similar advertisements if such abbreviations are commonly understood by consumers.
