Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light(s) will
come on when your
engine is started and
may stay on for
several seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if
the light comes on when you’re 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’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t
have anti-lock brakes and there’s a problem with
your regular brakes. See Brake System Warning
Light on page 201.
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 doesn’t come on then,
have it fixed so it will be ready to warn you if there
is a problem.
Traction Control System (TCS)
Warning Light
This warning light
should come on briefly
when the engine is
started.
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 it stays on, or comes on when you are
driving a SERVICE TRACTION CONTROL
message will appear in the Driver Information
Center (DIC). This indicates that there may be a
problem with your traction control system and your
vehicle may need service. When this warning light
is on and the SERVICE TRACTION CONTROL
message appears on the DIC, the system will not
limit wheel spin. Adjust your driving accordingly.
