2005 GMC SIERRA airbag off

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 with Your Four-Wheel-Drive Vehicle on
page 4-20for more tips on off-road driving.
Single Stage vs. Dual Stage Airbags
Depending on the weight of your vehicle you will have
either “Single Stage Airbags” or “Dual Stage Airbags”.
Vehicles that have a passenger sensing system
also have dual stage airbags. If the rearview mirror in
your vehicle has a passenger airbag status indicator
printed on it, your vehicle has the passenger sensing
system and therefore, it has dual stage airbags. If
the rearview mirror in your vehicle does not have a
passenger airbag status indicator printed on it, then your
vehicle does not have the passenger sensing system
and it has single stage airbags. SeePassenger
Airbag Status Indicator on page 3-36orPassenger
Sensing System on page 1-76.
Dual Stage Airbags
If your vehicle has frontal airbags with dual stage
deployment, the amount of restraint will adjust according
to crash severity. Your vehicle is equipped with electronic
frontal sensors which help the sensing system distinguish
between a moderate and a more severe frontal impact.
For moderate frontal impacts, these airbags inate at a
level less than full deployment. For more severe frontal
impacts, full deployment occurs. If the front of your
vehicle goes straight into a wall that does not move or
deform, the threshold level for the reduced deployment is
about 10 to 16 mph (16 to 25 km/h), and the threshold
level for a full deployment is about 20 to 25 mph
(32 to 40 km/h). (The threshold level can vary, however,
with specic vehicle design, so that it can be somewhat
above or below this range.)
Vehicle’s with dual stage airbags are also equipped with
special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensor provides
information which is used to determine if the airbags
should deploy at a reduced level or at full deployment.

Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the bag
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.
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.United States
Canada
1-73

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.
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.
1-74

To turn off the right front passenger’s airbag, insert your
ignition key into the switch, push in, and move the
switch to the off position.
The airbag off light will come on to let you know that the
right front passenger’s airbag is off. The light will stay
on to remind you that the airbag is off. The right
front passenger’s airbag will remain off until you turn it
back on.
{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off.
If your vehicle is a regular cab pickup or an
extended cab pickup and this ever happens,
do not let anyone whom the national
government has identied as a member of a
passenger airbag risk group sit in the right
front passenger’s position (for example, do not
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced. United States
Canada

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 onpage 3-36. 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 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 frontal 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. General
Motors recommends 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. Never put a child in a
rear-facing child restraint in the right front passenger seat
unless the passenger airbag status indicator shows off.
Never put a rear-facing child restraint in the right front
passenger seat unless the airbag is off.
{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
CAUTION: (Continued)
CAUTION: (Continued)
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 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. General Motors
recommends that rear-facing child restraints
be secured in a rear seat whenever possible,
even if the airbag is off.
The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
rear-facing infant seat
the system determines that a small child is present
in a forward-facing child restraint
1-77

the system determines that a small child is present
in a booster seat
a right front passenger takes his/her weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
or if there is a critical problem with the airbag
system or the passenger sensing system
When the passenger’s frontal airbag has been turned
off by the passenger sensing system, the off indicator
will light and stay lit to remind you that the airbag is off.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint
following the child restraint manufacturer’s directions
and refer toSecuring a Child Restraint in the Right Front
Seat Position (Regular and Extended Cab) (With
Airbag Off Switch) on page 1-56orSecuring a Child
Restraint in the Right Front Seat Position (Regular and
Extended Cab) (With Passenger Sensing System)
on page 1-62.If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle if one
is available and check with your dealer.
The passenger sensing system is designed to enable
(may inate) the right front passenger’s frontal
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 frontal
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.
1-78

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.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, 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’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-34for more on this, including
important safety information.
