2007 GMC Savana Van Owner's Manual - Page 235

Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have ABS. Locking Rear Axle If your vehicle has this feature, your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may feel the brakes vibrate, or you may notice some noise, but this is normal. 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. Braking in Emergencies With ABS, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. 235
