Anti-Lock Brake System Warning Light
I
PB005
With anti-lock, this light will go on when you start your engine and may stay
on for several seconds or
so. That's normal.
If
the light doesn't come on, have
it
fixed so
it
will be ready to warn you
if
there is a problem.
If the light stays on, or comes on when you're driving, your vehicle needs
service. Unless the regular brake system warning light is also on, you will still
have brakes, but not anti-lock brakes. If the regular brake system warning
light is also on, see "Brake System Warning Light" earlier in this section.
