Diplomats built from mid-1988 until the end of production were among the first Chrysler-built products to have a driver's side airbag as standard equipment, some two model years before the remainder of Chrysler's lineup (they were also among the only cars at the time to offer a tilt steering column with an airbag). Diplomats with airbags differed from earlier models in that they were also equipped with a padded, color-keyed knee blocker that extended out from beneath the instrument panel in front of the driver.
