CHEVROLET AVALANCHE 2007 2.G Owners Manual

When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or 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 loads are on: 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 Saver Active or
Service Battery Charging System. If this message
is displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 267.
Battery Run-Down Protection
This feature shuts off the dome lamps if they
are left on for more than 10 minutes when
the ignition is in LOCK. This will help prevent
the battery from running down.

Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help
you park while in REVERSE (R). It operates
only at speeds less than 5 mph (8 km/h).
URPA helps make parking easier and helps
you avoid colliding with objects such as parked
vehicles. The URPA system detects objects
that are close to the rear of the vehicle which are
at least 10 inches (25.4 cm) off the ground and
below hood or tailgate level. The system detects
objects up to 8 feet (2.5 m) behind your vehicle.
The URPA sensors determine how close
these objects are from your bumper within
this area.
{CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of
5 mph (8 km/h).
Detect objects more than
8 feet (2.5 meters) behind the
vehicle. This distance may be less
during warmer or humid weather.
Detect objects that are below the
bumper, underneath the vehicle,
or that are very close to the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
CAUTION: (Continued)
222

CAUTION: (Continued)
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.
The URPA display is
located above the rear
window towards the
center of the vehicle and
can be seen by looking
over your right shoulder.
The URPA display has three color-coded lights.
The lights are used to provide distance and system
information, along with beeps that will be heard
through the speakers.URPA can be turned off
by pressing the rear park
aid disable button
located next to the radio.
The indicator light will
come on to indicate
that URPA is off.
The red light in the URPA display will also be lit if
the vehicle is in REVERSE (R). If the vehicle has a
Driver Information Center (DIC), PARKING ASSIST
OFF will display on the screen. URPA automatically
turns back on each time the vehicle is started.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey come on to let you
know the display is operating correctly. URPA
comes on automatically when the shift lever
is moved into REVERSE (R).
The system does not work at a reverse speed
greater than 5 mph (8 km/h). To remind you of this,
the red light on the rear display will ash.
223

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA
detects objects close to the rear bumper. The
rst time an object is detected a single beep will
sound. If an object is detected at a REVERSE (R)
speed between 0 mph (0 km/h) and 5 mph
(8 km/h), the following describes what will occur
based on your distance to a detected object
located behind the vehicle:
At distances between 40 inches (1 m)
and 8 ft (2.5 m), a single amber light will
come on.
At distances between 23 inches (0.6 m)
and 40 inches (1 m), both amber lights
will be on.
At distances between 12 inches (0.3 m)
and 23 inches (0.6 m), all three lights
(amber/amber/red) will be on.
At distances less than 12 inches (0.3 m),
a beeping sound will repeat for a short
time and all three lights (amber/amber/red)
will ash.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARKING
ASSIST OFF will be displayed on the DIC screen
and a red light will come on the URPA display
when the shift lever is moved into REVERSE (R).
This occurs under the following conditions:
The driver disables the system.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of
your trunk during your last drive when you
turned off the vehicle. If the attached objects
are removed from your vehicle before the
start of your next drive, the system will return
to normal operation unless an object is
detected when the vehicle is shifted into
REVERSE (R). If this occurs, URPA assumes
the object is still attached, so you will have
to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.
224

The ultrasonic sensors are not kept clean.
So, be sure to keep your vehicle’s rear
bumper free of mud, dirt, snow, ice, and
slush. For cleaning instructions, seeWashing
Your Vehicle on page 541. If the DIC still
displays the PARKING ASSIST OFF
message after cleaning the bumper and
driving forward at a speed of at least
15 mph (25 km/h), see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver
action and the driver attempts to turn
URPA back on by pressing the rear park
aid button, the indicator light will ash
for 3 seconds and then stay lit to indicate
that URPA is off.As always, drivers should use care when
backing up a vehicle. Always look behind you,
being sure to check for other vehicles,
obstructions and blind spots.
For Driver Information Center messages
related to URPA, seeDIC Warnings and
Messages on page 267.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the
vehicle to your dealer to repair the system.
225

Accessory Power Outlet(s)
Your vehicle may have two accessory power
outlets located on the instrument panel.
Your vehicle may also have an outlet on the back
of the center console above the cupholder door.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.
Certain power accessory plugs may not be
compatible to the accessory power outlets and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer
for additional information on the accessory
power plugs.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or accessory
bracket from the plug because the power outlets
are designed for accessory power plugs only.
Ashtray(s) and Cigarette Lighter
If your vehicle has this feature it is located in the
center console or on the instrument panel. Pull up
on the ashtray door to open it if it is in the console or
pull the door open it if it is on the instrument panel.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite them
and possibly damage your vehicle. Never put
ammable items in the ashtray.
To remove the ashtray, pull it out from the console
or from the slide out door. To reinstall the ashtray,
slide it back to the original position.
To use the cigarette lighter, if the vehicle has one,
push it in all the way, and let go. When it is ready
for use, it will pop back out by itself.
Do not use the lighter to plug in accessory devices.
Use the power outlets provided.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from
the heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold
a cigarette lighter in while it is heating.

Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, defrost, defog and ventilation of
your vehicle.
Manual Operation
Turn the right knob clockwise or counterclockwise
to direct the airow inside of your vehicle.To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air
to the instrument panel outlets and to the
oor outlets. The ow can be divided between
vent and oor outlets depending upon where the
knob is placed between the settings. A little
air is directed towards the windshield and side
window outlets. Cooler air is directed to the
upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air
to the oor outlets, with some of the air directed
to the windshield, side window outlets, and
second row oor outlets. In this mode, the system
will automatically select outside air. Recirculation
cannot be selected when in Floor Mode.
The right knob can also be used to select defog
or defrost mode. For more information, see
“Defogging and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
227

The air conditioning compressor will be on unless
the outside temperature is close to freezing.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease
the fan speed. Turn the knob all the way
counterclockwise to turn the front system off.
:(Outside Air):Press this button to turn
on the outside air mode. When this mode
is selected, air from outside the vehicle will
circulate throughout your vehicle. An indicator
light on the button will come on to let you know
that it is activated. The outside air mode can
be used with all modes, but it cannot be used
with the recirculation mode. Pressing this button
again will cancel the recirculation mode.
?(Recirculation):Press this button to turn
on the recirculation mode. When the button
is pressed, an indicator light will come on.This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air
and prevent odors from entering your vehicle.
Recirculation may also help cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is less than the outside temperature.
The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
light will ash three times and turn off. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or
defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.
Temperature Control:Rotate the thumbwheels
up or down to increase or decrease the
temperature on the driver’s side or the passenger
side to the vehicle for the dual zone system.
228

#(Air Conditioning):Press this button on
the left knob to turn the air conditioning system
on or off. When A/C is pressed, an indicator
light will come on to let you know that the
air conditioning has been activated.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
The air conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath
your vehicle while idling or after turning off the
engine. This is normal.
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. Turn the right knob clockwise
to select the defog or defrost mode.
-(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):The defrost mode is used 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.
229

Rear Window Defogger
The rear window defogger uses a warming grid
to remove fog from the rear window.
<(Rear Window Defogger):Press this button
on the right knob to turn on the rear window
defogger. The system will automatically turn off
several minutes after it has been activated.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
Do not drive the vehicle until all the windows
are clear.
If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog
or frost from the surface of the mirror when
the rear window defog button is pressed.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you
could cut or damage the warming grid,
and the repairs would not be covered by
your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything
similar to the defogger grid.
Dual Automatic Climate
Control System
With this system, you can control the heating,
cooling and ventilation in your vehicle. Your
vehicle also has a ow-through ventilation system
described later in this section.
You can select different climate control settings
for the driver and passengers.
