12

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. Pull the seatback forward and fold it down until
it is at.
If the seatback cannot fold at because it
interferes with the cushion, try moving the front
seat forward and/or bringing the front
seatback more upright.
4. Repeat the steps for the other half of the
60/40 split bench seat.Returning the Seats to an Upright
Position
{CAUTION:
If the seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on the
seatback to be sure it is locked.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not
provide the protection needed in a crash.
The person wearing the belt could be
seriously injured. After raising the rear
seatback, always check to be sure that the
safety belts are properly routed and
attached, and are not twisted.
16

To return the seat(s) to the upright position, do the
following:
1. Lift the seatback up and push it rearward all
the way.
2. Lower the seat cushion until it latches into
position.
3. Pull forward on the seatback and up on
the seat cushion to make sure the seat is
securely in place.
4. Return the head restraints (SUV only) to the
upright position.
Third Row Seat (SUV)
Entering or Exiting the Third Row Seat
If your vehicle has a third row seat, you must
fold the second row seat down before entering or
exiting the third row. See “Folding the Seatbacks”
under60/40 Split Bench Seat on page 15
earlier in this section for instructions.
The third row seatback can be folded and the
entire seat can be tilted or removed from
the vehicle.
Folding the Seatback
To fold the seatback, do the following:
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.
1. Pull up on the
release lever
labeled 1, located on
the rear of the
seatback, and push
the seatback
forward.
17

Returning the Seat from a Tilted to an
Upright Position
{CAUTION:
If the seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on the
seatback to be sure it is locked.To return the seatback to an upright position, do
the following:
1. Pull the lever labeled 3 toward you.
2. While still holding lever 3 toward you, grasp
the top of the seat and pull it toward you
slightly.
19

3. Let go of lever 3 and pull the seat
completely down.
4. Push down on the seat rmly. Try pulling it up
to be sure it is locked into place.
5. Pull up on the
release lever
labeled 1 and then
pull up on the
seatback until the
seatback locks into
the upright position.Removing the Seat
To remove the seat, do the following:
1. Open the liftgate.
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.
2. Fold the seatback
forward onto the
seat cushion
by using the lever
labeled 1. The
seat cannot
be removed unless
the seatback is
folded.
20

{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 42. 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.
47

{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.
53

{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.
Second Row Center Position — SUT
1. If the child restraint manufacturer recommends
that the top tether be attached, attach the top
tether to the top tether anchor, if equipped.
Refer to the child restraint instructions and the
following steps:
1.1. To access the top tether anchor, raise
the passenger side seat cushion by
pulling up on the strap loop at the rear
of the seat cushion and fold the
seat cushion forward. Then fold the
seatback forward. See60/40 Split
Bench Seat on page 15for additional
information.
1.2. Place the child restraint in the center
seating position.
1.3. Find the top tether anchor at the rear
base of the center seat.

In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. Ination is determined by
what the vehicle hits, the angle of the impact, and
how quickly the vehicle slows down.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
SeeOff-Road Driving on page 317for more tips
on off-road driving.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is
in a crash. The sensing system triggers a release
of gas from the inator, which inates the
airbag. The inator, airbag, and related hardware
are all part of the airbag modules inside the
steering wheel and in the instrument panel in front
of the right front passenger.
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. The
airbag supplements the protection provided by
safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually.
But airbags would not help you in many types of
collisions, including rollovers, rear impacts,
and many side impacts, primarily because an
occupant’s motion is not toward those airbags.
Airbags should never be regarded as anything
more than a supplement to safety belts, and then
only in moderate to severe frontal or near-frontal
collisions.
