air condition GMC SIERRA 1500 2006 Owners Manual

Never put a child in a rear-facing child restraint in the right
front passenger seat unless your vehicle has the
passenger sensing system or an airbag off switch and the
passenger airbag status indicator or the airbag off light
shows off. Never put a rear facing child restraint in the
right front passenger seat unless the airbag is off. Here
is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. Be sure the
airbag is off before using a rear-facing child
restraint in the right front seat position.
Even though the passenger sensing system or
airbag off switch are designed to turn off the
passenger’s frontal airbag under certain
conditions, no system is fail-safe, and no one
can guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. General Motors
CAUTION: (Continued)
CAUTION: (Continued)
recommends that rear-facing child restraints
be transported in vehicles with a rear seat that
will accommodate a rear-facing child restraint,
whenever possible.
If you need to secure a forward-facing child
restraint in the right front seat, always move the
front passenger seat as far back as it will go.
It is better to secure the child restraint in a
rear seat.
{CAUTION:
A child in a child restraint in the center front
seat can be badly injured or killed by the right
front passenger’s airbag if it inates. Never
secure a child restraint in the center front seat.
It is always better to secure a child restraint in
the rear seat.
Do not use child restraints in the center front seat
position. The restraints will not work properly.

When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
Frontal airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbags could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. Ination is determined by what the vehicle hits,
the angle of the impact, and how quickly the vehicle
slows down.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving on page 4-16for more tips on off-road driving.

Airbag Off Switch
If your instrument panel has one of the switches pictured
in the following illustrations your vehicle has an airbag off
switch that you can use to turn off the right front
passenger’s airbag.This switch should only be turned to the off position if the
person in the right front passenger’s position is a member
of a passenger risk group identied by the national
government as follows:
Infant.An infant (less than 1 year old) must
ride in the front seat because:

my vehicle has no rear seat;
my vehicle has a rear seat too small to accommodate
a rear-facing infant seat; or
the infant has a medical condition which, according
to the infant’s physician, makes it necessary for the
infant to ride in the front seat so that the driver can
constantly monitor the child’s condition.
Child age 1 to 12.A child age 1 to 12 must
ride in the front seat because:

my vehicle has no rear seat;
although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space
is available in the rear seat(s) of my vehicle; or
the child has a medical condition which, according
to the child’s physician, makes it necessary for the
child to ride in the front seat so that the driver
can constantly monitor the child’s condition. United States
Canada
1-78

Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

causes the passenger airbag to pose a special risk
for the passenger; and
makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing the
passenger, even if belted, to hit the dashboard
or windshield in a crash.
{CAUTION:
If the right front passenger’s airbag is turned
off for a person who is not in a risk group
identied by the national government, that
person will not have the extra protection of an
airbag. In a crash, the airbag will not be able to
inate and help protect the person sitting
there. Do not turn off the passenger’s airbag
unless the person sitting there is in a risk
group.

To turn the right front passenger’s airbag on again,
insert your ignition key into the switch, push in,
and move the switch to the on position.
Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a
passenger sensing system. The indicator will be visible
when you turn your ignition key to RUN or START.
The words ON and OFF or the symbol for on and off,
will be visible on the rearview mirror during the system
check. When the system check is complete, either
the word ON or the word OFF, or the symbol for on or
the symbol for off will be visible.SeePassenger Airbag Status Indicator on page 3-37.If
your rearview mirror does not have either of the
indicators pictured below, then your vehicle does not
have the passenger sensing system.
The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag is not part of the passenger
sensing system. United States

Q:What if I added a snow plow? Will it keep the
airbags from working properly?
A:We have designed our airbag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles equipped with
the optional Snow Plow Prep Package (RPO
VYU). But do not change or defeat the snow plow’s
“tripping mechanism.” If you do, it can damage
your snow plow and your vehicle, and it may cause
an airbag ination.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my advanced airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the inside rearview mirror can affect the operation
of the advanced airbag system. If you have
questions, call Customer Assistance. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 7-2.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the airbag
may not work properly. You may have to replace the
airbag module in the steering wheel or both the
airbag module and the instrument panel for the right
front passenger’s airbag. Do not open or break
the airbag coverings.

h(Recirculation):The recirculation mode is used to
recirculate the air inside of your vehicle. Use this mode to
help prevent outside odors and/or dust from entering your
vehicle or to help cool the air inside of your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. The light on the recirculation button will
illuminate. Recirculation cannot be used in oor, defog
or defrost modes. An indicator on the button will light
up, ash three times and turn off when recirculation is
selected in these modes. 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 fan
speed.
Temperature Control
Driver’s Side:The lever on the left side of the climate
control panel is used to raise or lower the temperature on
the driver’s side of the vehicle. This lever also adjusts the
temperature to the center console outlets (if equipped).
Passenger’s Side:The lever on the right side of the
climate control panel is used to raise or lower the
temperature on the passenger’s side of the vehicle.#(Air Conditioning):Press this button to turn the
air-conditioning system on or off. When the button is
pressed, an indicator light will come on and the system
will begin to cool and dehumidify the air inside of your
vehicle. You may notice a slight change in engine
performance when the air conditioning compressor
shuts off and turns on again. 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 choose from
to clear fog or frost from your windshield. Use the defog
mode to clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.
Turn the right knob to select one of the following
modes:
-(Defog):This mode directs the air to the oor
outlets, windshield and the side window outlets.
The air conditioning compressor will run automatically
to dehumidify the air to prevent window fogging. The
recirculation mode cannot be selected while in the
defog mode.
3-23

1(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with only a little
air directed to the oor outlets. The air conditioning
compressor will run automatically to dehumidify the air to
prevent window fogging. The recirculation mode cannot
be selected while in defrost mode.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
If your vehicle has this feature, the lines you see on the
rear window warm the glass. The rear window defogger
uses a warming grid to remove fog from the rear window.
If your vehicle has a sliding rear window, you will not
have a rear window defogger; however, your vehicle will
still have a mirror button to activate the heated outside
rearview mirrors, if equipped.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light in the button will
come on to let you know that the rear window defogger
is activated. This button will also activate the heated
mirrors, if equipped.
The rear window defogger will automatically turn off
several minutes after the button is pressed. Pressing the
button while the defogger is running can also turn off the
defogger.
W(Mirror):If your vehicle does not have a rear
defogger and is equipped with heated mirrors, your
vehicle will have this button to activate the heated
mirrors.
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.

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 driver’s set temperature, delivery
mode and fan speed. Press the AUTO button again
within ve seconds to display the passenger’s set
temperature.
If the driver and passenger’s temperature settings
are not the same, the opposite side temperature
setting will be displayed for an additional
ve seconds. To make the passenger’s
temperature the same as the driver’s press and
hold the AUTO button for about four 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’s 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. Turn the driver’s or
passenger’s side temperature knob 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 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.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air is
available. The length of delay depends on the engine
coolant temperature. Pressing the fan switch will
override this delay and change the fan to a selected
speed.
