If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag:1. Turn the vehicle off. 2. Remove any additional material
from the seat, such as
blankets, cushions, seat
covers, seat heaters, or seat
massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. If the shoulder portion of the belt is pulled out all the way,
the child restraint locking
feature will be engaged. This
may unintentionally cause the
passenger sensing system to
turn the airbag off for some
adult-sized occupants. If this
happens, unbuckle the belt, let
the belt go back all the way,
and then buckle the belt again
without pulling the belt out all
the way.
6. Restart the vehicle and have the person remain in this
position for two to three minutes
after the on indicator is lit.
{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag
will not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
serious injury or even death. An
adult-sized occupant should not
ride in the front outboard
passenger seat, if the passenger
airbag off indicator is lit.
Additional Factors Affecting
System Operation
Seat belts help keep the passenger
in position on the seat during
vehicle maneuvers and braking,
which helps the passenger sensing
system maintain the passenger
airbag status. See “Seat Belts”and
“Child Restraints” in the Index for
additional information about the
importance of proper restraint use.

Warning (Continued)
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants and
all other children. Neither the
distance traveled nor the age and
size of the traveler changes theneed, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
(Continued)
Warning (Continued)
Never leave children unattended
in a vehicle and never allow
children to play with the seat
belts.
Every time infants and young
children ride in vehicles, they should
have the protection provided by
appropriate child restraints. Neither
the vehicle's seat belt system nor its
airbag system is designed for them.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
{Warning
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) (Continued)

the instructions that come with the
child restraint say that the top tether
must be attached.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position. SeeWhere to Put the
Restraint 094 for additional
information.
Securing a Child Restraint
Designed for the LATCH
System
{Warning
If a LATCH-type child restraint is
not attached to anchors, the child
restraint will not be able to protect
the child correctly. In a crash, the
child could be seriously injured or
killed. Install a LATCH-type child
restraint properly using the
anchors, or use the vehicle's seat
belts to secure the restraint,
(Continued)
Warning (Continued)
following the instructions that
came with the child restraint and
the instructions in this manual.
{Warning
To reduce the risk of serious or
fatal injuries during a crash, do
not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment
to come loose or even break
during a crash. A child or others
could be injured.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The(Continued)

shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
Buckle any unused seat belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
and tighten the belt behind the
child restraint after the child
restraint has been installed.

regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System) 095.
7. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the seat belt path and
attempt to move it side to side
and back and forth. When the
child restraint is properly
installed, there should be no
more than 2.5 cm (1 in) of

To remove the child restraint,
unbuckle the vehicle seat belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
