display CHEVROLET AVALANCHE 2008 2.G Owner's Manual

In order to prevent false temperature readings at
startup, the displayed temperature will not change until
the following occurs:
Vehicle speed is above 10 mph (16 kmh) for
5 minutes.
Vehicle speed is above 32 mph (51 kmh) for
2 and a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the air
delivery mode. The system may also supply cooler air to
the side of the vehicle facing the sun. The recirculation
mode will also be used as needed to maintain cool outlet
temperatures.
Defogging and Defrosting
Fog on the inside of the windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog or frost from your windshield.Use the mode up and down arrows to select the defog
or defrost modes.
-(Defog):The defog mode is used to clear the
windows of fog or moisture and warm the passengers.
This mode directs air to the windshield, oor outlets,
and side window vents. When you select this mode,
the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is close to freezing. The recirculation mode cannot be
selected while in the defog mode. Do not drive the
vehicle until all the windows are clear.
0(Defrost):Press this button to remove fog or frost
from the windshield more quickly. This mode directs
a portion of the air to the windshield and side window
vents and some to the oor vents. In this mode, the
system will automatically force outside air into your
vehicle. The recirculation mode cannot be selected while
in the defrost mode. The air conditioning compressor
will run automatically in this setting, unless the outside
temperature is close to freezing. Do not drive the
vehicle until all the windows are clear.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
Press the reset button, located on the instrument panel
cluster next to the trip odometer display, to toggle
between the trip odometer and the regular odometer.
Holding the reset button for approximately one second
while the trip odometer is displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s belt
is already buckled, neither the chime nor the light will
come on.

Voltmeter Gage
When your engine is not
running, but the ignition is
on, this gage shows
the battery’s state of
charge in DC volts.
When the engine is running, the gage 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 gage 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 gage 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. SeeDIC Warnings
and Messages on page 3-59andCharging System Light
on page 3-38for more information.
Brake System Warning Light
With the ignition on, the brake system warning light
will come on when you set the parking brake. If you
try to drive with the parking brake engaged, a chime
will sound when the vehicle speed is greater than
5 mph (8 km/h).
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on and a chime sounds there
could be a brake problem. Have your brake system
inspected right away.
3-39

Low Fuel Warning Light
This light, under the fuel
gage, will come on briey
when you are starting
the engine.
This light and a chime will come on when the fuel tank
is low on fuel. There will also be a “FUEL LEVEL LOW”
message on the Driver Information Center, seeDIC
Warnings and Messages on page 3-59for more
information. When you add fuel this light and message
should go off. If it does not, have your vehicle serviced.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
The DIC displays information about your vehicle. It also
displays warning messages if a system problem is
detected.
All messages will appear in the DIC display located
below the tachometer in the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
If your vehicle has DIC buttons, see “DIC Operation and
Displays (With DIC Buttons)” later in this section and
DIC Vehicle Customization (With DIC Buttons) on

(Trip/Fuel):Press this button to scroll through the
following menu items:
Odometer
Press the trip/fuel button until ODOMETER displays.
This display shows the distance the vehicle has
been driven in either miles (mi) or kilometers (km).
Pressing the trip odometer reset stem will also display
the odometer.
To switch between English and metric measurements,
see “Units” later in this section.
Trip Odometer
Press the trip/fuel button until TRIP displays. This
display shows the current distance traveled in either
miles (mi) or kilometers (km) since the last reset for the
trip odometer. Pressing the trip odometer reset stem
will also display the trip odometer.
The trip odometer can be reset to zero by pressing the
set/reset button while the trip odometer is displayed.
You can also reset the trip odometer while it is displayed
by pressing and holding the trip odometer reset stem.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles (kilometers) driven since the ignition was
last turned on. This can be used if the trip odometer is not
reset at the beginning of the trip.
To use the retro-active reset feature, press and hold
the set/reset button for at least four seconds. The trip
odometer will display the number of miles (mi) or
kilometers (km) driven since the ignition was last turned
on and the vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate mileage.
For example, if the vehicle was driven 5 miles (8 km)
before it is started again, and then the retro-active reset
feature is activated, the display will show 5 miles (8 km).
As the vehicle begins moving, the display will then
increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.

Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of
remaining miles (mi) or kilometers (km) the vehicle
can be driven without refueling. The display will
show LOW if the fuel level is low.
The fuel range estimate is based on an average of the
vehicle’s fuel economy over recent driving history and the
amount of fuel remaining in the fuel tank. This estimate
will change if driving conditions change. For example, if
driving in traffic and making frequent stops, this display
may read one number, but if the vehicle is driven on a
freeway, the number may change even though the same
amount of fuel is in the fuel tank. This is because different
driving conditions produce different fuel economies.
Generally, freeway driving produces better fuel economy
than city driving. Fuel range cannot be reset.
Average Economy
Press the trip/fuel button until AVG ECONOMY displays.
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of
mpg (L/100 km) recorded since the last time this menu
item was reset. To reset AVG ECONOMY, press and
hold the set/reset button.
Fuel Used
Press the trip/fuel button until FUEL USED displays.
This display shows the number of gallons (gal) or
liters (L) of fuel used since the last reset of this menu
item. To reset the fuel used information, press and hold
the set/reset button while FUEL USED is displayed.
Timer
Press the trip/fuel button until TIMER displays.
This display can be used as a timer.
To start the timer, press the set/reset button while
TIMER is displayed. The display will show the amount of
time that has passed since the timer was last reset, not
including time the ignition is off. Time will continue to be
counted as long as the ignition is on, even if another
display is being shown on the DIC. The timer will record
up to 99 hours, 59 minutes and 59 seconds (99:59:59)
