This gauge shows the engine
coolant temperature.
If the indicator needle moves to the
hot side of the gauge toward the
shaded area, the engine is too hot.
In eAssist vehicles, the engine
coolant warning light will come on
when the engine is too hot. See
Engine Coolant Temperature
Warning Light on page 5‑22 for
more information. If the vehicle has been operated
under normal driving conditions, pull
off the road, stop the vehicle, and
turn off the engine as soon as
possible.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
panel cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their safety belt. Then the light stays
on solid until the belt is buckled.This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver safety belt is buckled,
neither the light nor the chime
comes on.
Passenger Safety Belt
Reminder Light
When the vehicle is started, this
light flashes and a chime may come
on to remind front passengers to
fasten their safety belt. Then the
light stays on solid until the belt is
buckled.
For more information see

will light either ON or OFF to let you
know the status of the front
outboard passenger frontal airbag.
If the word ON is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag is allowed
to inflate.
If the word OFF is lit on the airbag
status indicator, it means that the
passenger sensing system has
turned off the front outboard
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong(Continued)
WARNING (Continued)
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5‑14 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer. If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, to produce
a cleaner environment. This light
comes on when the vehicle is
placed in ON/RUN for key access or
Service Only Mode for keyless
access, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer. See
Ignition Positions (Key Access) on

Black plate (16,1)Buick Regal Owner Manual - 2012
5-16 Instruments and Controls
page 9‑15orIgnition Positions
(Keyless Access) on page 9‑17 for
more information.
This light should come on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
If the malfunction indicator lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the dealer technician in correctly
diagnosing any malfunction. Notice:
If the vehicle is
continually driven with this light
on, the emission controls might
not work as well, the vehicle fuel
economy might not be as good,
and the engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Notice: Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than
those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to
costly repairs not covered by the
vehicle warranty. This could also
result in a failure to pass a
required Emission Inspection/
Maintenance test. See
Accessories and Modifications on
page 10‑3. This light comes on during a
malfunction in one of two ways:
Light Flashing:
A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park. Turn the
vehicle off, wait at least 10 seconds,
and restart the engine. If the light is
still flashing, follow the previous
steps and see your dealer for
service as soon as possible.
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.

rear window defogger may stay on
continuously. For vehicles with heated outside
rearview mirrors, they turn on with
the rear window defogger and help
to clear fog or frost from the surface
of the mirror. See
Heated Mirrors on
page 2‑15.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This

Climate Control Influence on
eAssist Operation and Fuel
Economy (If Equipped)
The climate control system is
dependent upon other vehicle
systems for heat and power input.
Certain climate control settings can
lead to higher fuel usage and/or
fewer Auto Stops.The following are climate control
settings that use more fuel:
.Comfort air conditioning mode.
.The defrost mode.
.Extreme temperature settings,
such as 60°F (15°C) /
90°F (32°C).
.High fan speed settings.
To help reduce fuel usage:
.Use the full automatic control as
described under Automatic
Operation.
.Use eco air conditioning, instead
of the comfort air conditioning.
.Select a temperature setting that
is higher in hot weather and
lower in cold weather.
.Turn off the air conditioning
when it is not needed.
.Only use defrost to clear the
windows.
