Antilock Brake System (Abs) Warning Light; Stabilitrak ® Indicator Light - GMC 2009 Yukon XL 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.
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 3-40.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-64 for all brake
