You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeeAirbag Off Switch on
page 93. If your child restraint is
forward-facing, move the seat as far back as
it will go before securing the restraint in
this seat. SeeManual Seats on page 9or
Power Seats on page 10. If you need to use a
rear-facing child restraint in this seat, make
sure the airbag is off once the child restraint
has been installed.
When the airbag off switch has turned off the
right front passenger’s frontal airbag, the
off indicator in the overhead console should
light and stay lit when you turn the ignition to
RUN or START after the system check is
completed. SeeAirbag Off Light on page 250.
2. Put the child restraint on the seat.3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
73

CAUTION: (Continued)
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.
If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, we
recommend that rear-facing child restraints not be
transported in your vehicle, even if the airbag is off.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 97. We recommend that
rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the
child restraint in this seat. SeeManual Seats
on page 9orPower Seats on page 10.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger
airbag status indicator should light and stay lit
when you turn the ignition to RUN or
START after the system check is completed.
SeePassenger Airbag Status Indicator on
page 252.
2. Put the child restraint on the seat.

{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.
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 word OFF or the off symbol will come on in
the passenger airbag status indicator located in the
overhead console to let you know that the right
front passenger’s airbag is off, after the system
check is completed. The airbag off light will come
on and stay on to let you know that the right
front passenger’s airbag is off. SeeAirbag Off Light
on page 250.

{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 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 the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Readiness
Light on page 250for additional
information.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.
The right front passenger’s frontal airbag is now
enabled (may inate). SeeAirbag Off Light
on page 250for more information.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not 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 airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 663.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates.
CAUTION: (Continued)
CAUTION: (Continued)
Avoid yellow connectors. They are
probably part of the airbag system. Be
sure to follow proper service procedures,
and make sure the person performing
work for you is qualied to do so.
The airbag system does not need regular
maintenance.
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.
