RSS also interacts with the tow/haul mode that, when engaged, will provide additional control of the shock absorbers. This additional control results in better ride and handling characteristics when the vehicle is loaded or towing a trailer. See "Tow/Haul Mode" under Towing a Trailer on page 375. StabiliTrak® System Your vehicle is equipped with StabiliTrak®, which combines antilock 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 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. The system should initialize before the vehicle reaches 20 mph (32 km/h). In some cases, it may take approximately two miles of driving before the system initializes. If the system fails to turn on or activate, the STABILITRAK OFF or SERVICE STABILITRAK message will be displayed. If the vehicle has gone through heavy acceleration or braking or multiple turns during the first two miles of driving after starting your vehicle, these messages may also appear. If this is the case, your vehicle does not need servicing. You will need to turn the vehicle off and then restart it to initialize StabiliTrak®. If either message appears on the Driver Information Center (DIC), and your vehicle hasn't gone through hard acceleration, braking or multiple turns in the first two miles of driving, your vehicle should be taken in for service. For more information on the stability messages, see Driver Information Center (DIC) on page 239. StabiliTrak® activates when the computer senses that your vehicle is just starting to spin, as it might if you hit a patch of ice or other slippery spot on the road. When the system activates, you may hear a noise or feel a vibration in the brake pedal. This is normal. The system is designed to help you in bad weather or other difficult driving situations by making the most of whatever road conditions will permit. 326
