For enhanced safety, the front shoulder belts of the GMC Acadia are height-adjustable, and the middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Acura MDX doesn’t offer comfort guides on its middle seat belts.
