You slam on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.
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 vibrate, or you may notice some noise, but this is
normal. On vehicles with four
-
wheel drive, your
anti
-
lock brakes work at all times
--
whether you are in
two
-
wheel drive or four
-
wheel drive.
Braking in Emergencies
With anti
-
lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
