Safety features include dual frontal airbags, side air curtains, seat-mounted side-impact airbags for driver and front-seat passenger, OnStar, anti-lock brakes, and StabiliTrak electronic stability control. Brake Assist has been added for 2008.
Air curtains are low-pressure air bags that come down from the ceiling and cover the side windows (of all three rows on the Acadia) to provide head protection in a side-impact crash or rollover; in a rollover the air curtains could also help keep arms and heads inside the vehicle. Studies by the Insurance Institute for Highway Safety (IIHS), which is funded by the insurance industry, have shown such head protection greatly improves the chance of surviving a side-impact crash. However, air curtains are not a substitute for seat belts. The front-seat side-impact air bags provide torso protection in a side-impact crash. IIHS studies have also shown these, too, are valuable, but not as important as head protection.
OnStar uses a global positioning system and an extra powerful cellular telephone to put the driver in touch with the OnStar center which is manned 24/7. The center can tell where the vehicle is located and send help or provide other assistance. Should the air bags deploy the system can automatically notify the OnStar center that an accident has occurred and where the vehicle is located so it can then send help. OnStar service is free for the first year but after that requires a subscription fee.
