StabiliTrak® System Your vehicle may have this feature. The StabiliTrak® system is an advanced computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is accomplished by selectively applying any one of the vehicle's brakes and reducing engine power. The StabiliTrak® system comes on automatically whenever you start your vehicle. The system cannot be turned off. The STABILITRAK NOT READY message may be displayed in the DIC and the traction control system and StabiliTrak® warning light on the instrument panel cluster will be on after first driving the vehicle and exceeding 30 mph 48 (km/h) for 30 seconds. The StabiliTrak® system is off until the light has turned off. This could take up to 15 minutes. The traction control system and StabiliTrak® warning light on the instrument panel cluster will flash when the system is operating. See Traction Control System (TCS) Warning Light on page 3-41, StabiliTrak® Indicator Light on page 3-42 and DIC Warnings and Messages on page 3-56 for more information. You may also feel or hear the system working. This is normal. The SERVICE STABILITRAK message will be displayed and the traction control system and StabiliTrak® warning light on the instrument panel cluster will come on if there is a problem with the system. When this light and the SERVICE STABILITRAK message are on, the system is not operational. Adjust your driving accordingly. Panic Brake Assist Your vehicle may have a panic brake assist system that monitors the intention of the driver while braking. If the system senses that the driver has applied hard/fast pressure to the brake pedal, the system will generate additional pressure, making it easier for the driver to maintain brake application. When this happens the brake pedal will feel easier to push. Just hold the brake pedal down firmly and let the system work for you. You may feel the brakes vibrate, or you may notice some noise but this is normal. The brakes will return to normal operation after the brake pedal has been released. 4-10
