2004 Chevrolet Silverado Owner ManualM

To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage
both the belt and your vehicle.
Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to be
seriously injured if they don’t wear safety belts.
A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible,
below the rounding, throughout the pregnancy.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.

6. Push and pull the child restraint in different
directions to be sure it is secure.
7. If your vehicle has the passenger sensing system
and the air bag is off, the off indicator will be lit and
stay lit in the inside rearview mirror when the key
is turned to RUN or START. Never put a rear-facing
child restraint in the right front passenger seat
unless the air bag 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 restraint.
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, use the air bag off switch to
turn off the air bag or secure the child in the child
restraint in a rear seat position in the vehicle if one is
available and check with your dealer. SeeAir Bag
Off Switch on page 1-73for more on this, including
important safety information.For heavy duty pickups without the passenger
sensing system, use the air bag off switch to turn the
air bag off or install the infant restraint in a rear
seat position.
{CAUTION:
If the air bag ON indicator comes on when you
have a rear-facing child restraint installed in
the right front passenger’s seat, it means that
the passenger sensing system has not turned
off the passenger’s frontal air bag. A child in a
rear-facing child restraint can be seriously
injured or killed if the right front passenger’s
air bag inates. This is because the back of
the rear-facing child restraint would be very
close to the inating air bag. Don’t use a
rear-facing child restraint in the right front
passenger’s seat unless the air bag is off.
To remove the child restraint, unhook the top tether
from the top tether anchorage and then disconnect the
LATCH attachments from LATCH anchorages.

6. To tighten the belt, push down on the child restraint,
pull the shoulder belt to tighten the lap belt portion
and feed the shoulder belt back into the retractor.
If you are using a forward-facing child restraint, you
may nd it helpful to use your knee to push
down on the child restraint as you tighten the belt.
You should not be able to pull more of the belt
out of the retractor once the lock has been set.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and the air bag is off, the off indicator will be lit and
stay lit in the inside rearview mirror when the key
is turned to RUN or START. Never put a rear-facing
child restraint in the right front passenger seat
unless the air bag 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.
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.

To turn off the right front passenger’s air bag, insert
your ignition key into the switch, push in, and move the
switch to the off position.
The AIR BAG OFF light will come on to let you know
that the right front passenger’s air bag is off. The
right front passenger’s air bag will remain off until you
turn it back on again, and the AIR BAG OFF light
will stay on to remind you that the air bag is off.
{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger’s air bag
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,
don’t let anyone whom the national
government has identied as a member of a
passenger air bag risk group sit in the right
front passenger’s position (for example, don’t
secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.United States with

To turn the right front passenger’s air bag on again,
insert your ignition key into the switch, push in,
and move the switch to the ON or AUTO 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 Air
Bag Status Indicator on page 3-40. 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 air bag under certain
conditions. The driver’s air bag is not part of the
passenger sensing system. In addition to the passenger
sensing system, your vehicle has an air bag off switch
located on the instrument panel.Passenger Air Bag Status Indicator – United States

Servicing Your Air
Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don’t want the system to
inate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper
service. You can be injured if you are close to
an air bag when it inates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualied to do so.
The air bag system does not need regular maintenance.
Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly. Also, the air bag system may not
work properly if you relocate any of the air bag
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. See″Customer Satisfaction Procedure″in
the Index.
