Safety Alert Seat
The GM-patented Safety Alert Seat provides the driver the option of getting haptic seat-bottom vibration pulses instead of audible crash avoidance alerts.
Forward Collision Alert
If the system detects that a front-end collision situation is imminent while following a detected vehicle, the system alerts the driver to a potential collision. It also alerts the driver if the driver is following a detected vehicle much too closely.
