Anti-Lock Brake System
Warning Light
If the light stays on, or comes on when 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 3-28.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so it will
be ready to warn you if there is a problem.
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on
for several seconds.
That's normal.
Traction Control System (TCS)
Warning Light
(Automatic Transmission)
The TC (traction control) warning light will come on
briefly when you turn the ignition to ON. If it doesn't
come on then, have it fixed so it will be ready to warn
you if there is a problem.
If the Traction Control System (TCS) is on and you drive
faster than 100 mph (161 km/h), the system will turn
off and the TC warning light will come on. The TCS will
turn back on and the TC warning light will go out
once the vehicle speed falls below 90 mph (145 km/h).
If the TC (traction control) warning light stays on or
comes on while you are driving, pull off the road as soon
as possible and stop carefully. Try resetting the system
by turning the ignition off then back on. If the light
still stays on or comes back on again while you are
driving, your vehicle needs service. Have the traction
control system inspected as soon as possible.
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system.
