The anti
-
lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti
-
lock doesn’t 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 won’t 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
anti
-
lock brakes.
Using Anti
-
Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti
-
lock work for you. You may feel the
brakes pulsate, or you may hear air exhausting, but this
is normal.
