Because many automatic belt system designs compliant with the US passive-restraint mandate did not meet the seatbelt anchorage requirements of Canada (CMVSS 210) — which were not weakened to accommodate automatic belts — vehicle models which had been eligible for easy importation in either direction across the US-Canada border when equipped with manual belts became ineligible for importation in either direction once the US variants obtained automatic belts and the Canadian versions retained manual belts. Two particular models affected were the Dodge Spirit and Plymouth Acclaim.
