StabiliTrak, the electronic stability control system shown to dramatically reduce single-vehicle crashes, gives precise, all-weather control, especially helpful in most emergency situations. Sophisticated sensors continually monitor the driver's sterring commands and vehicle response-and make adjustments automatically when necessary to help the driver keep on track. Already standard on many GM full-size SUVs. StabiliTrak will be standard on all GM utilities and vans by the end of 2007.
