seat or the safety belts. Always unbuckle
the safety belts and return them to their normal
stowed position before folding a rear seat.To fold the seatback:
1. Make sure there is nothing on or under
the seat.
2. Disconnect the rear safety belt mini-latch,
using a key in the slot on the mini-buckle,
let the belt retract into the headliner. Stow
the mini-latch in the holder located in
the headliner.
21

4. Make sure the safety belt is not twisted, and
reconnect the center safety belt mini-latch to
the mini-buckle.
5. Pull on the safety belt to be sure the mini-latch
is secure.
Removing the Third Row Seats
1. Remove the cargo management system, if it is
in the vehicle. SeeCargo Management System
on page 164.
2. Make sure there is nothing on or under
the seat.
Notice:Folding a rear seat with the safety belts
still fastened may cause damage to the seat or
the safety belts. Always unbuckle the safety
belts and return them to their normal stowed
position before folding a rear seat.
3. Fold the seatback down. See Folding the
Seatback earlier in this section.
4. Remove the rear bolts located on the oor on
each side of the seat.
5. Remove the seat by tilting it slightly upward,
and then pulling it out of the rear of the vehicle
in one motion.
6. Put the bolts back into the holes on the oor so
the nuts do not get misplaced.
Installing the Third row Seats
1. Make sure the seatback is folded forward
before installing the seat. See Folding the
Seatback earlier in this section.
The seats must be placed in the proper
locations for the legs to attach correctly. The
wider seat must be installed on the driver
side and the narrower seat on the passenger
side. Make sure to remove the bolts from
the holes in the oor before installing
the seats.
2. Place the seat on the vehicle oor so that the
front seat hooks are on the vehicle bars.
3. Reinstall the bolts, and torque to 55
Y
(41 lb ft). Pull up on the seat to make sure
it is locked in place.
4. Raise the seatback to its upright position.
Push and pull on the seatback to make
sure it is locked into place.
5. Push the headrest up into position. Push and
pull on the headrest to make sure it is locked
into place.

{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt cannot properly spread the
impact forces. In a crash, the two children
can be crushed together and seriously
injured. A belt must be used by only one
person at a time.
Q:What if a child is wearing a lap-shoulder
belt, but the child is so small that the
shoulder belt is very close to the child’s
face or neck?
A:If the child is sitting in a seat next to a
window, move the child toward the center of
the vehicle. Also seeRear Safety Belt
Comfort Guides on page 43. If the child is
sitting in the center rear seat passenger
position, move the child toward the safety belt
buckle. In either case, be sure that the
shoulder belt still is on the child’s shoulder, so
that in a crash the child’s upper body would
have the restraint that belts provide.
49

{CAUTION:
The body structure of a young child is
quite unlike that of an adult or older child,
for whom the safety belts are designed. A
young child’s hip bones are still so small
that the vehicle’s regular safety belt may
not remain low on the hip bones, as it
should. Instead, it may settle up around
the child’s abdomen. In a crash, the belt
would apply force on a body area that is
unprotected by any bony structure. This
alone could cause serious or fatal injuries.
Young children always should be secured
in appropriate child restraints.
Child Restraint Systems
An infant car bed (A), a special bed made for use
in a motor vehicle, is an infant restraint system
designed to restrain or position a child on a
continuous at surface. Make sure that the infant’s
head rests toward the center of the vehicle.
55

{CAUTION:
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck and the safety belt
continues to tighten. Secure any unused
safety 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, if your vehicle has
one, after the child restraint has been
installed. Be sure to follow the instructions
of the child restraint manufacturer.
Notice:Contact between the child restraint or
the LATCH attachment parts and the vehicle’s
safety belt assembly may cause damage to
these parts. Make sure when securing unused
safety belts behind the child restraint that
there is no contact between the child restraint
or the LATCH attachment parts and the
vehicle’s safety belt assembly.Folding an empty rear seat with the safety
belts secured may cause damage to the safety
belt or the seat. When removing the child
restraint, always remember to return the safety
belts to their normal, stowed position before
folding the rear seat.
1. Attach and tighten the lower attachments to
the lower anchors. If the child restraint does
not have lower attachments or the desired
seating position does not have lower anchors,
secure the child restraint with the top tether
and the safety belts. Refer to your child
restraint manufacturer instructions and the
instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Recline the seatback to the full reclined
position.
Make sure the second row bench
seatbacks are aligned at the same
angle before placing the child restraint
on the seat. Make sure the third
row bench seatbacks are both upright
before placing the child restraint on
the seat.

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas
from the inator. Gas from the inator lls
the airbag causing the bag to break out of the
cover and deploy. The inator, the airbag,
and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with seat-mounted side impact airbags, there
are airbag modules in the side of the front
seatbacks closest to the door. For vehicles with
roof-rail airbags, there are airbag modules in
the ceiling of the vehicle, near the side windows
that have occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact the
steering wheel or the instrument panel. In
moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.Airbags supplement the protection provided by
safety belts.
Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body,
stopping the occupant more gradually.
Seat-mounted side impact and roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants
in the outboard seating positions in the rst,
second, and third rows. The rollover capable
roof-rail airbags are designed to help reduce the
risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of
collisions, primarily because the occupant’s motion
is not toward those airbags. SeeWhen Should
an Airbag Inflate? on page 81for more information.
Airbags should never be regarded as anything
more than a supplement to safety belts.
83

You may want to consider not using seat covers
or other aftermarket equipment. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 91for more information about modications
that can affect how the system operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
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/retailerand the service manual have information about
servicing your vehicle and the airbag system.
To purchase a service manual, seeService
Publications Ordering Information on page 535.
{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. 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.
