For a number of years now, General Motors has offered specially calibrated engines for areas at very reasonable prices. Weve done this for two reasons. First, the performance and driveability of regular engines are diminished when operated in areas where air density is lower usually at altitudes over 4,000 feet. Second, studies show that vehicles not specifically calibrated for these areas generally emit higher levels of high-altitu- de certain emissions when operated at high altitudes. Now, to make sure that all GM areas enjoy the customers in dual benefits of better performance and lower emissions, a special calibration procedure will be performed by your GM dealer prior to the time you take delivery. There is absolutely no charge for this service. high-altitu- de General Motors and your Chevrolet, Pontiac, Oldsmobilc, Buick, Cadillac and GMC Truck dealer want cleaner air for everyone.
