Front Passenger's Seat Child-Restraint
System Installation (With Front
Passenger Occupant Classifi cation
System)
1. Switch the ignition ON.
2. Slide the seat as far back as possible.
3. Place the child-restraint system on the seat without putting your weight on
the seat and fasten the seat belt. See
the manufacturer's instructions on the
child-restraint system for belt routing
instructions.
4. To get the retractor into the automatic locking mode, pull the shoulder belt
portion of the seat belt until the entire
length of the belt is out of the retractor.
5. Push the child-restraint system fi rmly
into the vehicle seat. Be sure the
belt retracts as snugly as possible. A
clicking noise from the retractor will
be heard during retraction if the system
is in automatic locking mode. If the
belt does not lock the seat down tight,
repeat the previous step and also this
one.
NOTE
 y  Inspect this function before each use of
the child-restraint system. You should
not be able to pull the shoulder belt
out of the retractor while the system is
in the automatic locking mode. When
you remove the child-restraint system,
be sure the belt fully retracts to return
the system to emergency locking mode
before occupants use the seat belts.
 y Follow the child-restraint system
manufacturer's instructions carefully.
 Depending on the type of child-restraint system, it may not employ seat belts
which are in automatic locking mode.
6. Seat your child safely in the child- restraint system and secure the child
according to the instructions from the
child-restraint system manufacturer.
7. Make sure the front passenger air bag deactivation indicator light illuminates
after installing a child-restraint system
on the front passenger seat.
If the front passenger air bag deactivation indicator light does not
illuminate, remove the child-restraint
system, switch the ignition to OFF, and
then re-install the child-restraint system
(page 2-57 ).

If your vehicle is also equipped with a front passenger occupant classifi cation system,
refer to the Front Passenger Occupant Classifi cation System (page 2-57 ) for details.
If your vehicle is equipped with a front passenger occupant classifi cation system, the front
passenger air bag deactivation indicator light illuminates for a specifi\
ed time after the
ignition is switched ON.
Small children must be protected by a child-restraint system as stipulat\
ed by law in every
state and province. In certain states and provinces, larger children must use a child-restraint
system (page 2-23 ).
Carefully consider which child-restraint system is necessary for your ch\
ild and follow
the installation directions in this Owner's Manual as well as the child-\
restraint system
manufacturer's instructions.
WARNING
Seat belts must be worn in air bag equipped vehicles: Depending only on the air bags for protection during an accident is dangerous. Alone,
air bags may not prevent serious injuries. The appropriate air bags can be expected to
infl ate only in the fi rst accident, such as frontal, near frontal or side collisions or roll-over
accidents that are at least moderate. Vehicle occupants should always wear seat belts.

Children should not ride in the front passenger seat: Placing a child, 12 years or under, in the front seat is dangerous. The child could be hit
by a deploying air bag and be seriously injured or even killed. A sleeping child is more
likely to lean against the door and be hit by the side air bag in moderate collision to the
front-passenger side of the vehicle. Whenever possible, always secure a child 12 years and
under on the rear seats with an appropriate child-restraint system for the child's age and
size.
