Anti-Lock Brake System Warning Light; Traction Control System (Tcs) Warning Light - Buick Lucerne 2007 Owner's Manual

Anti-Lock Brake System
Warning Light
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 203.
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.
204
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.
Traction Control System (TCS)
Warning Light
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.
This warning light
should come on
briefly when the
engine is started.
