22 Seats and Restraints
Adjust the head restraint so that the top of
the restraint is at the same height as the
top of the occupant's head. This position
reduces the chance of a neck injury in a
crash.
The height of the head restraint can be
adjusted. Pull the head restraint up to raise
it. Try to move the head restraint to make
sure that it is locked in place.
To lower the head restraint, press the
button, located on the top of the seatback,
and push the restraint down. Try to move
the head restraint after the button is
released to make sure that it is locked in
place.The front seat outboard head restraints are
not removable.
Rear Head Restraints
Crew Cab
The vehicle’s rear seats have head restraints
in the outboard seating positions that
cannot be adjusted up or down.
The rear outboard head restraints are
designed to be folded. When folding the
seatback down, the head restraint must first
be manually folded forward out of the way
to fold the seatback down.
The head restraint can be folded forward to
allow for better visibility when the rear seat
is unoccupied. To fold the head restraint,
press the button on the side of the head
restraint.
When an occupant is in the seat, always
return the head restraint to the upright
position until it locks into place. Push and
pull on the head restraint to make sure that
it is locked.
If you are installing a child restraint in the
rear seat, see
Lower Anchors and Tethers for
Children (LATCH System) 050.
Extended Cab
The vehicle’s rear seats have headrests in
the outboard seating positions that cannot
be adjusted.
If you are installing a child restraint in the
rear seat, see Lower Anchors and Tethers for
Children (LATCH System) 050.

is turned off. The alert does not directly
detect objects in the rear seat; instead,
under certain conditions, it detects when a
rear door is opened and closed, indicating
that there may be something in the
rear seat.
The feature is active only once each time
the vehicle is turned on and off, and will
require reactivation by opening and closing
the second row doors. There may be an
alert even when there is nothing in the rear
seat; for example, if a child entered the
vehicle through the rear door and left the
vehicle without the vehicle being shut off.
The feature can be turned on or off. See
Vehicle Personalization099.
Folding the Rear Seat
On crew cab models, the rear seatbacks can
be folded forward.
Caution
Folding a rear seat with the seat belts
still fastened may cause damage to the
seat or the seat belts. Always unbuckle
the seat belts and return them to their
normal stowed position before folding a
rear seat. To fold a rear seatback:
1. Fold the head restraint. See Head
Restraints 021.
2. Disconnect the rear center seat belt latch
from the mini-buckle by inserting the tip
of the seat belt tongue into the slot on
the buckle. Let the belt retract.
3. Pull the release strap on the outboardside of the seatback.
4. Fold the seatback forward.
To return a seatback to the upright position: 1. Lift the seatback up and push it rearward.
2. Return the head restraint to the upright position. See Head Restraints 021.
{Warning
If either 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 seatbacks to be sure they are locked.

30 Seats and Restraints
Never wear the shoulder belt under both
arms or behind your back.
Always use the correct buckle for your
seating position.
Never route the lap or shoulder belt over an
armrest.
{Warning
The seat belt can be pinched if it is
routed under plastic trim on the seat,
such as trim around the rear seatback
folding handle or side airbag. In a crash,
pinched seat belts might not be able to
provide adequate protection. Never allow
seat belts to be routed under plastic trim
pieces.
Lap-Shoulder Belt
All seating positions in the vehicle have a
lap-shoulder belt.If you are using a rear seating position with
a detachable seat belt and the seat belt is
not attached, see
Rear Seats025 for
instructions on reconnecting the seat belt to
the mini-buckle.
The following instructions explain how to
wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how,
see “Seats” in the Index.
2. Pick up the latch plate and pull the belt
across you. Do not let it get twisted.

Seats and Restraints 55
For extended cab without rear seat and crew
cab models, there are top tether anchor
symbols to assist you in locating the top
tether anchors.
Crew Cab
The top tether anchors in a crew cab model
are on the back wall behind each rear
seating position. Fold down the rear
seatback to access the anchor. See
instructions for crew cab under Rear Seats
0 25. Be sure to use an anchor located
directly behind the seating position where
the child restraint will be placed.
Extended Cab with Rear Seats
The top tether anchors in an extended cab
model are loops near the top of each rear
seatback. See the instructions under
“Securing a Child Restraint with the LATCH
System” later in this section on how to
attach a top tether.
Do not attach a top tether to the loop near
the top of the seatback of the seating
position in which the child restraint is
installed.Extended Cab without Rear Seats
The top tether anchor in an extended cab
without rear seats is a metal wire on the
lower inboard side of the cab wall directly
behind the front passenger seat.
Do not place heavy objects on the top
tether anchor or use it as a tie down for
cargo as this may cause damage to the
anchor.
Do not secure a child restraint in a position
without a top tether anchor if a national or
local law requires that the top tether be
attached, or if the instructions that come
with the child restraint say that the top
tether must be attached.

56 Seats and Restraints
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 049 for
additional information.
Securing a Child Restraint with the
LATCH System
{Warning
A child could be seriously injured or killed
in a crash if the child restraint is not
properly attached to the vehicle using
either the LATCH anchors or the vehicle
seat belt. Follow 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
(Continued)
Warning (Continued)
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 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
(Continued)
Warning (Continued)
tighten the belt behind the child restraint
after the child restraint has been
installed.
Caution
Do not let the LATCH attachments rub
against the vehicle’s seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments.
Do not fold the rear seatback when the
seat is occupied. Do not fold the empty
rear seat with a seat belt buckled. This
could damage the seat belt or the seat.
Unbuckle and return the seat belt to its
stowed position, before folding the seat.
If you need to secure more than one child
restraint in the rear seat, see Where to Put
the Restraint 049.

Driving 0174. Two-Tiered Loading
Depending on the model of the pickup,
an upper load platform can be created
by positioning three or four 5 cm (2 in)
by 15 cm (6 in) wooden planks across
the width of the pickup box. The planks
must be inserted in the pickup box
depressions.
When using this upper load platform,
be sure the load is securely tied down
to prevent it from shifting. The load's
center of gravity should be positioned
in a zone over the rear axle. The zone is
located in the area between the front
of each wheel well and the rear of each
wheel well. The center of gravity height
must not extend above the top of the
pickup box flareboard.
Any load that extends beyond the
vehicle's taillamp area must be properly
marked according to local laws and
regulations.
