Brake System Warning; Light - Cadillac CTS 2012 Owner's Manual

Cadillac CTS/CTS-V Owner Manual (Mid-East) - 2012
The vehicle may not pass
inspection if:
The malfunction indicator lamp is
on with the engine running, or
if the light does not come on
when the ignition is turned to
ON/RUN while the engine is off.
The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.

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.
This light should come on briefly
when the ignition is placed in
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem.
Black plate (25,1)
Instruments and Controls
When the ignition is on, the brake
system warning light also comes on
when the parking brake is set.
The light flashes or stays on if the
parking brake is not fully released.
If the light stays on after the parking
brake is fully released, there is a
base brake problem.
CAUTION
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.
