GMC 2005 Savana - Manual (Page 197)

StabiliTrak ® System
If your vehicle has StabiliTrak ® , it combines anti-lock
brake, traction and stability control systems and
helps the driver maintain directional control of the
vehicle in most driving conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks to
ensure that it is working properly. You may hear or feel
the system working. This is normal and does not
mean there is a problem with your vehicle. The system
should initialize before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take approximately
2 miles (3.2 km) of driving before the system initializes.
The following chart describes the StabiliTrak ® not
ready light and the StabiliTrak ® indicator light.
