Brakes
Antilock Brake
System (ABS)
This vehicle might have the Antilock
Brake System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on. This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock
Brake System (ABS) Warning Light
on page 5
‑ 28 .
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.
