belt CHEVROLET AVALANCHE 2007 2.G Workshop Manual

The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s airbag
should be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding
in a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{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.
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
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. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
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.
82

The passenger sensing system is designed to
enable (may inate) the right front passenger’s
airbag anytime the system senses that a person
of adult size is sitting properly in the right front
passenger’s seat. When the passenger sensing
system has allowed the airbag to be enabled,
the on indicator will light and stay lit to remind
you that the airbag is active.
For some children who have outgrown child
restraints and for very small adults, the passenger
sensing system may or may not turn off the right
front passenger’s airbag, depending upon the
person’s seating posture and body build. Everyone
in your vehicle who has outgrown child restraints
should wear a safety belt properly — whether or
not there is an airbag for that person.
If a person of adult-size is sitting in the right
front passenger’s seat, but the off indicator is lit,
it could be because that person is not sitting
properly in the seat. If this happens, turn
the vehicle off and ask the person to place the
seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended.Restart the vehicle and have the person remain
in this position for about two minutes. This
will allow the system to detect that person and
then enable the passenger’s airbag.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep
the airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height, front
end or side sheet metal, they may keep the
airbag system from working properly. Also,
the airbag system may not work properly if you
relocate any of the airbag sensors. If you have
any questions about this, you should contact
Customer Assistance before you modify your
vehicle. 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 582.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, rollover sensor
module, steering wheel, instrument panel,
overhead console, ceiling headliner, ceiling
and pillar garnish trim, roof-mounted rollover
airbag modules, or airbag wiring can affect the
operation of the 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 582.

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. Keep safety belts clean and
dry. SeeCare of Safety Belts on page 540
for more information.
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,
or the side impact airbag covering on the
ceiling near the side windows, the airbag may
not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or
side impact airbag module and ceiling covering
for roof-mounted rollover airbags (if equipped).
Do not open or break the airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
in your vehicle. A damaged restraint
system may not properly protect the
person using it, resulting in serious
injury or even death in a crash. To help
make sure your restraint systems are
working properly after a crash, have
them inspected and any necessary
replacements made as soon as possible.
If you have had a crash, do you need new belts
or LATCH system parts?
After a very minor collision, nothing may be
necessary. But if the belts were stretched, as
they would be if worn during a more severe
crash, then you need new parts.
If the LATCH system was being used during
a more severe crash, you may need new
LATCH system parts.If belts are cut or damaged, replace them.
Collision damage also may mean you will need
to have LATCH system, safety belt or seat
parts repaired or replaced. New parts and repairs
may be necessary even if the belt or LATCH
system was not being used at the time of
the collision.
If an airbag inates, you will need to replace
airbag system parts. See the part on the airbag
system earlier in this section.
If the frontal airbags inate you will also need to
replace the driver and front passenger’s safety belt
retractor assembly. Be sure to do so. Then the
new retractor assembly will be there to help protect
you in a collision.
After a crash you may need to replace the
driver and front passenger’s safety belt retractor
assemblies, even if the frontal airbags have
not deployed. The driver and front passenger’s
safety belt retractor assemblies contain the
safety belt pretensioners. Have your safety belt
pretensioners checked if your vehicle has been
in a collision, or if your airbag readiness light stays
on after you start your vehicle or while you are
driving. SeeAirbag Readiness Light on page 242.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children,
can easily open the doors and fall out
of a moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash
if the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
CAUTION: (Continued)

Young children who get into unlocked
vehicles may be unable to get out.
A child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke.
Always lock your vehicle whenever
you leave it.
Outsiders can easily enter through
an unlocked door when you slow
down or stop your vehicle. Locking
your doors can help prevent this
from happening.
There are several ways to lock and unlock
the doors.
To lock or unlock the door from the outside,
use the remote keyless entry (RKE) transmitter
or the key.
To lock or unlock the door from the inside, slide
the manual lever up or down, or use the power
door locks switch.

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 Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
people to buckle their safety belts. The driver
safety belt light will also be provided and stay on
for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light
will be repeated if
the driver remains
unbuckled and
the vehicle is
in motion.
If the driver’s belt is buckled, neither the chime
nor the light will come on.
241

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.
242

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light
on page 242.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the engine is
not running, as a check
to show you it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving, you
may have a problem with the charging system.
It could indicate that you have problems with the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your battery.
When this light comes on, the Driver Information
Center (DIC) will also display the SERVICE
BATTERY NOT CHARGING SYSTEM message.
SeeDIC Warnings and Messages on page 267
for more information.
If you must drive a short distance with the light
on, be certain to turn off all your accessories,
such as the radio and air conditioner, to reduce
the drain on your battery.
