Brake System Warning Light; Electric Parking Brake Light; Light - Cadillac XTS Owner's Manual

122 INSTRUMENTS AND CONTROLS
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
Only 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

The vehicle brake system consists of
two hydraulic circuits. If one circuit is
not working, the remaining circuit can
still work to stop the vehicle. For
normal braking performance, both
circuits need to be working.
If the warning light comes on, there is
a problem with the braking system.
Have the brake system inspected
right away.
This light should come on briefly
when the engine is started. 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 base brake problem.
Warning
The brake system might not be
working properly if the brake
system warning light is on. Driving
Warning (Continued)
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.
Electric Parking Brake
Light
The parking brake status light comes
on when the parking brake is applied.
If the light continues flashing after
the parking brake is released, or while
driving, there is a problem with the
electric parking brake system or
another system. A message may also
display in the Driver Information
Center (DIC). See Brake System
