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.
EnglishMetric
The Brake System Warning Light
should come on briefly as the
engine is started. If it does not come
on, have the vehicle serviced by
your dealer.
{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,
a chime sounds. Pull off the road
and stop. The pedal might be harder
to push or go closer to the floor.
It might also take longer to stop.
If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 10‑74.
Electric Parking Brake
Light
EnglishMetric
The parking brake status light
comes on when the 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. A SERVICE
PARKING BRAKE message
may also display on the Driver
Information Center (DIC). See Brake
System Messages on page 5‑26 for
more information.
If the light does not come on,
or remains flashing, see your dealer.

Instruments and Controls 5-17
The brake warning light should
come on briefly when the ignition is
placed in ON/RUN. If it does not
come on, have the vehicle serviced
by your dealer.
If this light comes on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. SeeParking
Brake on page 9‑31 for more
information.
Antilock Brake System
(ABS) Warning Light
The Antilock Brake System (ABS)
light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
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. A chime may also sound when
the light comes on steady. Then
start the engine again to reset the
system. If the ABS light 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
Brake System Warning Light on
page 5‑16.
See Driver Information Center (DIC)
on page 5‑22 for all brake related
DIC messages.
Ultrasonic Parking
Sensor Light
This light comes on to indicate that
there is a malfunction in the system.
See your dealer for service.

Traction Off Light
This light comes on briefly while
starting the engine.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
The traction off light comes on when
the Traction Control System (TCS)
has been turned off or if there is a
problem with the TCS.
If the light comes on and stays on
while the system is turned on, the
vehicle needs service.
A message also appears in the
Driver Information Center (DIC).
SeeRide Control System Messages
on page 5‑29 for more information. See

information.
StabiliTrak®OFF Light
This light comes on when the
StabiliTraK system is turned off.
If the Traction Control System (TCS)
is off, wheel spin is not limited.
If StabiliTrak is off, the system does
not assist in controlling the vehicle.
Turn on the TCS and the StabiliTrak
system and the warning light
turns off.

Traction Control System
(TCS)/StabiliTrak®Light
The Traction Control System (TCS)/
StabiliTrak Light comes on briefly
when the engine is started.
If the light does not come on, have
the vehicle serviced by the dealer.
If the system is working normally,
the indicator light turns off.
If the light is on while certain DIC
messages display, this indicates
that the TCS and StabiliTrak
systems are not working or are
disabled.

Black plate (19,1)Buick Regal Owner Manual - 2011
Instruments and Controls 5-19
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. Check
the DIC messages to determine
which feature(s) is no longer
functioning and whether it is
because of the driver turning off the
feature(s), or because the system is
not working properly and the vehicle
requires service.
If the TCS is disabled, wheel spin is
not limited. If the StabiliTrak system
is disabled, the system does not aid
in maintaining directional control of
the vehicle.
If the indicator/warning light is on
and flashing, the TCS or the
StabiliTrak system is actively
working. Check the DIC messages
for details to determine which
system is working. If the LOW
TRACTION message appears, the
system is limiting wheel spin. If a
message appears in the DIC, the
system is aiding in maintaining
directional control of the vehicle.See
StabiliTrak®System on
page 9‑36 andTraction Control
System (TCS) on page 9‑34 for
more information.
See Ride Control System Messages
on page 5‑29 for more information
on the messages associated with
this light.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine
is started. It provides information
about tire pressures and the TPMS. When the Light Is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A tire pressure message can
accompany the light. See
Tire
Messages on page 5‑30 for more
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label.
See Tire Pressure on page 10‑49
for more information.
When the Light Flashes First and
Then Is On Steady
This indicates that there may be a
problem with the TPMS. The light
flashes for about a minute and
stays on steady for the remainder of
the ignition cycle. This sequence
repeats with every ignition cycle.
See Tire Pressure Monitor
Operation on page 10‑52 for
more information.

Tire Pressure
The display will show a vehicle with
the approximate pressures of all
four tires. Tire pressure is displayed
in either kilopascal (kPa) or pounds
per square inch (psi). SeeTire
Pressure Monitor System on
page 10‑51 andTire Pressure
Monitor Operation on page 10‑52
for more information.
Remaining Oil Life
This display shows an estimate
of the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See Engine Oil Messages on
page 5‑28. The oil should be
changed as soon as possible. See
Engine Oil on page 10‑9. In addition
to the Engine Oil Life System monitoring the oil life, additional
maintenance is recommended in the
Maintenance Schedule in this
manual. See
Scheduled
Maintenance on page 11‑2 for more
information.
Remember, the Remaining Oil Life
display must be reset after each
oil change. It will not reset itself.
Also, be careful not to reset the
Remaining Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
Engine Oil Life System, press SET/
CLR while the Remaining Oil Life
display is active. See Engine Oil
Life System on page 10‑13.
Compass
The vehicle has a compass display
in the DIC. See Compass on
page 5‑4 for more information.
Vehicle Messages
Messages displayed on the DIC
indicate the status of the vehicle or
some action that may be needed
to correct a condition. Multiple
messages may display one after
the other.
The messages that do not
require immediate action can be
acknowledged and cleared by
pressing SET/CLR. The messages
that require immediate action cannot
be cleared until that action is
performed. All messages should be
taken seriously and clearing the
messages does not correct the
problem.
