2007 Buick Rainier Owner's Manual - Page 290

When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If driving conditions delay system initialization, the STABILITRAK NOT READY message may be displayed. If this is the case, your vehicle does not need servicing. For more information on the stability messages, see DIC Warnings and Messages on page 202. When the StabiliTrak® system is both on and actively controlling the stability of the vehicle, the StabiliTrak® light will blink for the duration of the event. You may also feel or hear the system working. This is normal. The StabiliTrak® disable button is located on the transmission shift handle. The StabiliTrak® system has three modes of operation: STABILITRAK ON, TRACTION CONTROL OFF, and STABILITRAK OFF. STABILITRAK ON - The vehicle will default to STABILITRAK ON every time the driver starts the vehicle. The StabiliTrak® light will be off and no DIC messages will be displayed. TRACTION CONTROL OFF - The driver can modify the engine speed management system by momentarily pressing the StabiliTrak® button on the transmission shift handle. The StabiliTrak® light will come on and TRACTION CONTROL OFF will be displayed. For vehicles without a DIC, the StabiliTrak® indicator light will come on. Momentarily pressing the StabiliTrak® button again will return the system to the STABILITRAK ON mode. 290
