Along with ABS, the vehicle has a
Dynamic Rear Proportioning (DRP)
system. If there is a DRP problem,
both the brake and ABS warning
lights come on accompanied by a
10 second chime. The lights and
chime will come on each time the
ignition is turned on until the
problem is repaired. See your dealer
for service.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and
continue braking. Here is what
happens with ABS:
A computer senses that the 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.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
antilock work. You might feel the
brakes vibrate or hear some noise,
but this is normal.
Braking in Emergencies
If the vehicle has ABS, it allows the
driver to steer and brake at the
same time. However, if the vehicle
does not have ABS, the first
reaction, to hit the brake pedal hard

and hold it down, might be the
wrong thing to do. The wheels can
stop rolling. Once they do, the
vehicle cannot respond to the
driver's 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 the driver was
trying to avoid, or into traffic.
If the vehicle does not have ABS,
use a squeeze braking technique.
This gives maximum braking while
maintaining steering control. 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 helps
retain steering control. With ABS, it
is different.
In many emergencies, steering can
help more than even the very best
braking.
