4. Press the trip/fuel button untilthe vehicle heading, for
example, N for North, is
displayed in the DIC. Or, if the
vehicle does not have DIC
buttons, press and hold the
trip odometer reset stem for
two seconds to select the next
available variance zone. Repeat
this step until the appropriate
variance zone is displayed.
5. If calibration is necessary, calibrate the compass.
See “Compass Calibration
Procedure” following. Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an
open parking lot, where driving the
vehicle in circles is not a danger.
It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB or
cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle, move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone
is set to the variance zone in
which the vehicle is located.
See “Compass Variance (Zone)
Procedure” earlier in this
section.
Do not operate any switches
such as window, sunroof,
climate controls, or seats during
the calibration procedure.
2. Press the vehicle information button until PRESS
VTO
CALIBRATE COMPASS
displays. Or, if the vehicle does
not have DIC buttons, press the
trip odometer reset stem until
CALIBRATE COMPASS
displays.

Vehicle Messages
Messages displayed on the DIC
indicate the status of the vehicle or
some action may be needed to
correct a condition. Multiple
messages may appear one after
another.
The messages that do not require
immediate action can be
acknowledged and cleared by
pressing
V(Set/Reset) or the trip
odometer reset stem.
The messages that require
immediate action cannot be cleared
until that action is performed.
All messages should be taken
seriously and clearing the message
does not correct the problem.
The following are the possible
messages and some information
about them.
Battery Voltage and
Charging Messages
BATTERY LOW START
VEHICLE
When the vehicle’ s battery is
severely discharged, this
message will display and
four chimes will sound. Start the
vehicle immediately. If the vehicle
is not started and the battery
continues to discharge, the climate
controls, heated seats, and audio
systems will shut off and the vehicle
may require a jump start. These
systems will function again after the
vehicle is started.
SERVICE BATTERY
CHARGING SYSTEM
On some vehicles, this message
displays if there is a problem
with the battery charging system.
Under certain conditions, the
charging system light may also turn
on in the instrument panel cluster. See
Charging System Light on
page 5‑20. Driving with this problem
could drain the battery. Turn off all
unnecessary accessories. Have the
electrical system checked as soon
as possible. See your dealer.
Brake System Messages
SERVICE BRAKE SYSTEM
This message displays along with
the brake system warning light if
there is a problem with the brake
system. See Brake System Warning
Light on page 5‑23. If this message
appears, stop as soon as possible
and turn off the vehicle. Restart the
vehicle and check for the message
on the DIC display. If the message
is still displayed or appears again
when you begin driving, the brake
system needs service as soon as
possible. See your dealer.

Black plate (8,1)Chevrolet Avalanche Owner Manual - 2011
6-8 Lighting
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on,
such as: headlamps, high beams,
fog lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY LOW
START VEHICLE . If this message
displays, it is recommended that the
driver reduce the electrical loads as
much as possible and restart the
vehicle. See
Battery Voltage and
Charging Messages on page 5‑37.Battery Power Protection
This feature shuts off the dome
lamps if they are left on for more
than 10 minutes when the ignition is
in LOCK/OFF. This helps to prevent
the battery from running down.
