Antilock Brake System (Abs) Warning Light - GMC Sierra 2010 Owner's Manual

Antilock Brake System (ABS)
Warning Light
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
4-40
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on, the
vehicle does not have antilock brakes and there is a
problem with the regular brakes. See Brake System
Warning Light on page 4 39.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages on page 4 65 for all
brake related DIC messages.
