Using Abs; Braking In Emergencies; Locking Rear Axle - Chevrolet 2006 Avalanche Owner's Manual

ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
4-8
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.

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.

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.

Locking Rear Axle

If your vehicle has this feature, it 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.
