Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2012
WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push
or can go closer to the floor. It may
take longer to stop. If the light does
not go out, have the vehicle towed
for service. See General Towing
Information on page 9 16.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is in
ON/RUN.
That is normal. If the light does not
come on then, have it fixed so it
will be ready to warn if there is a
problem.

Instruments and Controls
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
still 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 Fuel Economy Gauge
on page 5 5.
See Driver Information Center (DIC)
on page 5 11 for all brake related
DIC messages.
