Anti-Lock Brake System

Warning Light

If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the brake system warning light is not on,
you still have brakes, but you do not have anti-lock
brakes. See Brake System Warning Light on page 3-36.
If the light stays on, turn the ignition to OFF. 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 3-36.
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.

Traction Control System (TCS)

Warning Light
The TC (traction control) warning light will come on
briefly when you turn the ignition to RUN. If it does not
come on then, have it fixed so it will be ready to
warn you if there is a problem.
The light will also come on if you turn the traction
control system off using the TC (traction control) on/off
button located near the shift lever.
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 and, if equipped, the StabiliTrak
inspected as soon as possible. See Traction Control
System (TCS) on page 4-8 and StabiliTrak
page 4-9 for more information.
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system
and, if equipped, the
