Power Outlet 110 Volt Alternating
Current
The vehicle may have a power
outlet that can be used to plug in
electrical equipment with a
maximum limit of 150 watts.
The power outlet is located on the
rear of the center console.
An indicator light on the outlet
comes on when in use. The light
comes on when the ignition is in
ON/RUN, equipment requiring lessthan 150 watts is plugged into the
outlet, and no system fault is
detected.
The indicator light on the outlet will
not turn on if the plug is not fully
seated.
If you try to connect equipment
using more than 150 watts or a
system fault is detected, the
equipment may operate for a
short period and turn itself off.
A protection circuit shuts off the
power supply and the indicator light
turns off. To reset the circuit, unplug
the item and plug it back in or turn
the Remote Accessory Power (RAP)
off and then back on. See
Retained
Accessory Power (RAP) on
page 9‑24. Prolonged usage of the
power outlet at the maximum load of
150 watts may cause the outlet to
overheat and automatically shut
down. The power restarts when
equipment that operates within the
limit is plugged into the outlet and a
system fault is not detected. The power outlet is not designed for
the following equipment, and may
not work properly if any of the
following is plugged in:
.Equipment with high initial
peak wattage such as:
compressor-driven refrigerators
and electric power tools.
.Other equipment requiring
an extremely stable
power supply such as:
microcomputer-controlled
electric blankets, touch sensor
lamps, etc.

Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper‐resistant
odometer. The digital odometer will
read 999,999 if it is turned back.
If the vehicle needs a new odometer
installed, it must be set to the
mileage total of the old odometer.
If that is not possible, then it must
be set at zero and a label must be
put on the driver door to show the
old mileage reading when the new
odometer was installed.
Trip Odometer
The trip odometer can show how far
the vehicle has been driven since
the trip odometer was last reset.The trip odometer is accessed and
reset through the Driver Information
Center (DIC). See
Driver
Information Center (DIC) on
page 5‑25 for more information.
Tachometer
The tachometer displays the
engine speed in revolutions per
minute (rpm).
For eAssist vehicles, when the
ignition is in ON/RUN, the
tachometer indicates the vehicle
status. When pointing to AUTO, the
engine is off but the vehicle is on
and can move. The engine could
auto start at any time. When the
indicator points to OFF, the vehicle
is off.
When the engine is on, the
tachometer will indicate the engine’s
revolutions per minute (rpm). The
tachometer may vary by several
hundred rpm’s, during auto stop
mode, when the engine is shutting
off and restarting. A slight bump may be felt when the
transmission is determining the
most fuel efficient operating range.
Fuel Gauge
When the ignition is on, the fuel
gauge shows about how much fuel
is left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
When the vehicle's fuel level
becomes low, a message appears
in the Driver Information Center

Black plate (12,1)Buick Regal Owner Manual - 2012
5-12 Instruments and Controls
(DIC) and a single chime sounds.
SeeFuel System Messages on
page 5‑32 for more information.
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge moves a little while
turning a corner or speeding up.
.The gauge takes a few seconds
to stabilize after the ignition is
turned on, and will go back to
empty when the ignition is
turned off.
Driver Efficiency Gauge
For eAssist vehicles, this gauge
assists in driving efficiently and may
vary based on driver input.
To maximize efficiency, keep the
gauge pointed in the solid green
zone in the center of the gauge.
The gauge moves to the left when
braking and to the right when
accelerating. When either is done
aggressively, the vehicle is being
driven less efficiently and the gauge
will move further from the center.

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

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.
