Anti-Lock Brake System
Warning Light
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you are driving, stop as soon
as possible and turn the ignition off. Then start
the engine again to reset the system. If the light still
stays on, or comes on again while you are driving, your
vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-27.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key to RUN. This
is normal. If the light does not come on then, have it
fixed so it will be ready to warn you if there is a problem.
3-28
If your vehicle is equipped
with the anti-lock brake
system, the light will come
on when your engine is
started and may stay on
for several seconds.
That is normal.
Enhanced Traction System
Warning Light
United States
If your vehicle has the Enhanced Traction
System (ETS), this warning light should come on briefly
as you start the engine. If the warning light does not
come on then, have it fixed so it will be ready to warn
you if there is a problem.
If the warning light stays on, or comes on when you are
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
