Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts.
When the engine is running, the
gauge shows the condition of the
charging system. The charging
system regulates voltage based
on the state of the battery for improved fuel economy and battery
life. The gauge may transition from
a higher to lower or a lower to
higher reading, this is normal.
Readings between the low and high
warning zones indicate the normal
operating range. The gauge may
also read low during the fuel
economy mode, this is normal.
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
at an idle for an extended period.
This condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create full
power. If there is a problem with the
battery charging system, this light
will come on or the SERVICE
BATTERY CHARGING SYSTEM
DIC message will display. See
Battery Voltage and ChargingMessages on page 5‑18
and
Charging System Light on
page 5‑18 for more information.
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.

Notice:If you drive the vehicle
while the engine oil pressure is
low, severe engine damage may
occur. If a low oil pressure
warning appears on the Driver
Information Center (DIC), stop the
vehicle as soon as possible. Do
not drive the vehicle until the
cause of the low oil pressure is
corrected. See Engine Oil on
page 10‑8 for more information.
This message displays if low oil
pressure levels occur. Stop the
vehicle as soon as safely possible
and do not operate it until the cause
of the low oil pressure has been
corrected. Check the oil as soon as
possible and have the vehicle
serviced by your dealer. See Engine
Oil on page 10‑8.
Engine Power Messages
ENGINE POWER IS REDUCED
This message displays and a chime
sounds when the cooling system
temperature gets too hot and the
engine further enters the engine
coolant protection mode. See
Engine Overheating on page 10‑22
for further information.
This message also displays when
the engine power is reduced.
Reduced engine power can affect
the vehicle's ability to accelerate.
If this message is on, but there is no
reduction in performance, proceed
to your destination. The
performance may be reduced the
next time the vehicle is driven. The
vehicle may be driven at a reduced
speed while this message is on, but
acceleration and speed may be
reduced. Anytime this message
stays on, the vehicle should be
taken to your dealer for service as
soon as possible.

Transmission Messages
SERVICE 4 WHEEL DRIVE
This message displays if a problem
occurs with the four-wheel-drive
system. If this message appears,
stop as soon as possible and turn
off the vehicle. Make sure the key is
in the LOCK/OFF position for at
least one minute and then restart

TRANSMISSION HOT IDLE
ENGINE
Notice: If you drive the vehicle
while the transmission fluid is
overheating and the transmission
temperature warning is displayed
on the instrument panel cluster
and/or DIC, you can damage the
transmission. This could lead to
costly repairs that would not be
covered by the warranty. Do not
drive the vehicle with overheated
transmission fluid or while the
transmission temperature
warning is displayed.
This message displays along with a
sound if the transmission fluid in the
vehicle gets hot. Driving with the
transmission fluid temperature high
can cause damage to the vehicle.
Stop the vehicle and let it idle to
allow the transmission to cool. This
message clears and the chime
stops when the fluid temperature
reaches a safe level.

Lighting 6-3
Exterior Lamps Off
Reminder
If a door is open, a reminder chime
sounds when the headlamps or
parking lamps are manually turned
on and the key is out of the ignition.
To turn off the chime, turn the
headlamp switch to off or AUTO and
then back on, or close and re-open
the door. In the AUTO mode, the
headlamps turn off once the ignition
is in LOCK/OFF or remains on until
the headlamp delay ends (if enabled
in the DIC). See“Exit Lighting”
under Vehicle Personalization (With
DIC Buttons) on page 5‑45.
Headlamp High/
Low-Beam Changer
5 3
(Headlamp High/Low
Beam Changer): To change the
headlamps from low to high beam,
push the lever toward the instrument
panel. To return to low-beam
headlamps, pull the multifunction
lever toward you. Then release it.
When the high beams are on, this
indicator light on the instrument
panel cluster will also be on.
Flash-to-Pass
Use your high-beam headlamps to
signal to a driver in front that you
want to pass. It works even if the
headlamps are in the automatic
position.
To use it, pull the turn signal lever
toward you, then release it.
If the headlamps are in the
automatic position or on low beam,
the high-beam headlamps turn on.
They stay on as long as the lever is
held. The high-beam indicator on
the instrument panel cluster comes
on. Release the lever to return to
normal operation.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system comes on when
the following conditions are met:
.The ignition is on.
.The exterior lamps control is
in AUTO.
.The transmission is not in Park.
.The light sensor determines it is
daytime.
When the DRL system is on,
only the DRL lamps are on. The
taillamps, sidemarker, instrument
panel lights, and other lamps will not
be on.
When it begins to get dark, the
automatic headlamp system
switches from DRL to the
headlamps.

Black plate (4,1)Chevrolet Avalanche Owner Manual - 2012
6-4 Lighting
To turn off the DRL lamps, turn the
exterior lamps control to the OFF
position and then release. For
vehicles first sold in Canada, the
transmission must be in the P (Park)
position before the DRL lamps can
be turned off.
Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps along with
other lamps such as the taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover this sensor or
the system will come on whenever
the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage, a tunnel, or while
driving in heavy overcast weather.
This is normal.There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp systems so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system is only affected
when the light sensor sees a
change in lighting lasting longer
than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately one minute
for the automatic headlamp system
to change to DRL if it is light
outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6‑7.
