Tire Pressure Monitoring System

2008 GMC Acadia
"Proper tire inflation is an important element of safe driving. It always has been, said Jim Gutting, GM's director of Tire-Wheel Systems group." The GM vehicles that monitor tire pressure use either the antilock brake system (ABS) or separate sensors mounted in each wheel. A warning light on the instrument panel or message displayed on the driver information center, along with an audible warning, alerts the driver to check the air pressure in their tires. An estimated 83 percent of tire pressure loss occurs gradually — often without being noticed by the driver.

Tips on Tire Safety
- Poorly maintained and improperly used tires can be dangerous.
- Overloading your tires can cause overheating as a result of too much deflection. You could have a blow out and a serious accident. See your Owner's Manual about vehicle loading.
- Underinflated tires pose the same danger as overloaded tires. Check all tires frequently to maintain the recommended pressure as listed on the vehicle's tire placard. Tire pressure should be checked when tires are "cold," which means your vehicle has been sitting for at least three hours, or you've driven it no more than a mile.
- Overinflated tires are more likely to give a harsh ride and to exhibit rapid tread wear in the center of the tire. Keep tires at recommended pressure.
- Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.
