2007 CHEVROLET AVALANCHE sensor

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.

Automatic Operation
AUTO (Automatic):When automatic operation
is active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system
in automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current temperature(s)
and AUTO will be lit on the display. The
current delivery mode and fan speed will also
be displayed for approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor
will run when the outside temperature is over
about 40°F (4°C). The air inlet will normally
be set to outside air. If it is hot outside, the
air inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will illuminate
in recirculation.2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
74°F (23°C) temperature setting and allow
about 20 minutes for the system to regulate.
Use the driver’s or passenger’s temperature
buttons to adjust the temperature setting
as necessary. If you choose the temperature
setting of 60°F (15°C), the system will
remain at the maximum cooling setting.
If you choose the temperature setting of
90°F (32°C), the system will remain at the
maximum heat setting. Choosing either
maximum setting will not cause the vehicle
to heat or cool any faster.
Be careful not to cover the solar sensor located
on the top of the instrument panel near the
windshield. This sensor regulates air temperature
based on sun load and also turns on your
headlamps. For more information on the solar
sensor, see “Sensors” later in this section.
232

Sensors
The solar sensor, located in the defrost grille,
middle of the instrument panel, monitors the
solar radiation. Do not cover the solar sensor
or the system will not work properly.There is also an interior temperature sensor
located next to the steering wheel that measures
the temperature of the air inside your vehicle.
There is also an exterior temperature sensor
located behind the front grille. This sensor reads
the outside air temperature and helps maintain
the temperature inside the vehicle. Any cover
on the front of the vehicle could cause a
false reading in the displayed temperature.
236

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.

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds
to remind the front passenger to buckle their safety
belt. The passenger safety belt light will also
come on and stay on for several seconds, then
it will ash for several more.
This chime and light
will be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled,
neither the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag
System on page 72.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go out. This means the
system is ready.
