Voltmeter Gauge
When the engine is not running, but
the ignition is turned on, this gauge
shows the battery's state of charge
in DC volts.
When the engine is running, this
gauge shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate. This is normal. Readings between
the low and high warning zones
indicate the normal operating range.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
idling for an extended period.
If there is a problem with the battery
charging system, a SERVICE
BATTERY CHARGING SYSTEM
message will appear in the Driver
Information Center (DIC) and/or the
charging system light comes on.
See
Battery Voltage and Charging
Messages on page 5‑32 for more
information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
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 chime nor the light
comes on.

Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), passenger
sensing system, the pretensioners,
the airbag modules, the wiring, and
the crash sensing and diagnostic
module. For more information on the
airbag system, see
Airbag System
on page 3‑23.
The airbag readiness light comes on
for several seconds when the
vehicle is started. If the light does
not come on then, have it fixed
immediately.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on.
See Airbag System Messages on
page 5‑38.

Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. SeePassenger
Sensing System on page 3‑30 for
important safety information. The
instrument panel has a passenger
airbag status indicator.
United States
Canada and Mexico
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds as a system check. If you use
remote start, if equipped, to start the
vehicle, you may not see the system
check. Then, after several more
seconds, the status indicator will
light either ON or OFF, or either the
on or off symbol to let you know the
status of the front outboard
passenger frontal airbag.
If the word ON or the on symbol 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 or the off symbol is
lit on the passenger 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
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See
Airbag 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

Black plate (16,1)Acadia/Acadia Denali Owner Manual - 2013 - crc2 - 12/11/12
5-16 Instruments and Controls
a check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays the SERVICE BATTERY
CHARGING SYSTEM message.
SeeVehicle Messages on
page 5‑31 for more information.
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, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
ON/RUN, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer. See
Ignition Positions on page 9‑14.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that the OBD
II system has detected a problem
and diagnosis and service might be
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 also
assists the service 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/

Black plate (17,1)Acadia/Acadia Denali Owner Manual - 2013 - crc2 - 12/11/12
Instruments and Controls 5-17
Maintenance test. See
Accessories and Modifications on
page 10‑2.
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 towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, find a
safe place to stop and park the
vehicle. 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.
The following may correct an
emission control system
malfunction:
.Check that the fuel cap is fully
installed. See Filling the Tank on
page 9‑41. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑38.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.

This light may also come on due to
low brake fluid. SeeBrake Fluid on
page 10‑20.
When the ignition is on, the brake
system warning light will also come
on when the parking brake is set.
The light will stay on if the parking
brake does not release fully. If it
stays on after the parking brake is
fully released, it means there is a
brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is fully
released. The pedal may be harder
to push or, the pedal may go closer
to the floor. It may take longer to
stop. If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 10‑71.{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.
The brake message remains on until
any DIC button is pressed. The
brake light remains on until the
problem is fixed. See Brake System
Messages on page 5‑32.
Antilock Brake System
(ABS) Warning Light
The ABS warning light comes on
briefly when the ignition key is
turned to ON/RUN. This is normal.
If the light does not come on then,
have it fixed so it will be ready to
warn you if there is a problem.
If the light stays on, turn the ignition
to LOCK/OFF. If the light comes on
while driving, stop as soon as
possible and turn the ignition off.
Then start the engine again to reset
the system. If the light still stays on,
or comes on again while driving, the
vehicle needs service. If the regular
brake system warning light is not
on, there are still brakes, but no
antilock brakes. If the regular brake
system warning light is also on,
