Brake System Warning; Light - Cadillac XT6 2023 Owner's Manual

136 Instruments and Controls
The DLC is under the
instrument panel to the left of
the steering wheel.
Connecting devices that are
not used to perform an
Emissions Inspection/
Maintenance test or to service
the vehicle may affect vehicle
operation. See Add-On
Electrical Equipment 0 360.
See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
The light is on when the
engine is running.
The light does not come on
when the ignition is in
Service Mode.
Critical emission control
systems have not been
completely diagnosed. If this
happens, the vehicle would
not be ready for inspection
and might require
several days of routine
driving before the system is
ready for inspection. This
can happen if the 12-volt
battery has recently been
replaced or run down, or if
the vehicle has been
recently serviced.
See your dealer if the vehicle
will not pass or cannot be
made ready for the test.
Brake System
Warning Light
Metric English
This light comes on briefly
when the vehicle is turned on
to show that the light is
working. If it does not come on
then, have it fixed so it will be
ready to warn you if there is a
problem.
If the light comes on and stays
on, there is a brake problem.
Have the brake system
inspected right away. This
light may come on if the brake
fluid is low. See Brake Fluid
0 384.
If the light comes on while
driving, pull off the road and
stop carefully. If equipped with
electric brake boost, vehicle
speed may be limited when the
brake system warning light
comes on. The brake pedal
might be harder to push,
or the brake pedal may go
closer to the floor. It could
take longer to stop. If the light
is still on, have the vehicle
towed for service. See
Transporting a Disabled
Vehicle 0 437.
