Brake System Warning Light; Parking Brake Light - Cadillac ATS 2017 Owner's Manual

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 brake problem. Have the brake
system inspected right away.
Metric English
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 brake problem.
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.
