Remember: Anti-lock 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 anti-lock brakes.

Using Anti-Lock

Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.

Braking in Emergencies

At some time, nearly every driver gets into a situation
that requires hard braking.

If you have anti-lock, you can steer and brake at the
same time. However, if you do not have anti-lock, your
first reaction — to hit the brake pedal hard and hold
it down — may be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle can not
respond to your steering. Momentum will carry it
in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.

If you do not have anti-lock, use a “squeeze” braking
technique. This will give you maximum braking
while maintaining steering control. You can do this by
pushing on the brake pedal with steadily increasing
pressure.

In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If you do have
anti-lock, it is different. See “Anti-Lock Brake System”
in this section.

In many emergencies, steering can help you more than
even the very best braking.

Traction Control System (TCS)

Your vehicle may have a traction control system that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the front wheels are spinning or
beginning to lose traction. When this happens,
the system works the front brakes and reduces engine
power to limit wheel spin.

The LOW TRAC message will be displayed when the
traction control system is limiting wheel spin. See
Low Traction Message on page 3-42. You may feel or
hear the system working, but this is normal.
