Section 1 Seats and Restraint Systems
1-1
Fore-and-Aft Adjustment
The fore-and-aft
adjustment lever is
located underneath the
seat, in the front.
To slide the seat forward or rearward, move the lever
toward the driver’s door. The seat will lock in at 1/2 inch
(1.5 cm) increments.
{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
press rearward on the seatback to be sure it
is locked.
Reclining Seatbacks
If your vehicle has non-suspension bucket seats, you
can recline the seatbacks. The lever is located on
the outboard side of the seat cushion.
To recline the seatback, lift the lever and use your body
to move the seatback. Release the lever to lock the
seatback where you want it. Lean forward and pull up on
the lever to return the seatback to an upright position.
1-4
Split Bench Seat (80/20 Split)
If your vehicle has a split bench seat, your seat is
not adjustable.
There is a storage area underneath the seat cushion.
SeeStorage Areas on page 2-47.
Air Suspension Seats
Your vehicle may have a low-back or high-back air
suspension seat. There are two ways you can adjust
the seat.
Height Adjustment
The suspension seat
height adjustment lever
is located on the front
inboard side of the seat.
To adjust the height of the air suspension seat, pull the
lever up to inflate. Push the lever down to deflate.
1-6
{CAUTION:
Newborn infants need complete support,
including support for the head and neck.
This is necessary because a newborn infant’s
neck is weak and its head weighs so much
compared with the rest of its body. In a crash,
an infant in a rear-facing seat settles into
the restraint, so the crash forces can be
distributed across the strongest part of an
infant’s body, the back and shoulders. Infants
always should be secured in appropriate infant
restraints.
{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.
We know securing a child can present real problems
in a medium-duty vehicle like yours.
If your vehicle is a regular cab model with an
air-suspension seat in the right front passenger’s
position, there is no place in your vehicle to secure a
child restraint. The only answer is to have smaller
children make the trip in another vehicle, where they
can get the protection they need.
1-32
Where to Put the Restraint
(Regular Cab Models)
If your vehicle is a regular cab model with an
air-suspension seat in the right front passenger’s
position, there is no place in your vehicle to secure a
child restraint. The only answer is to have smaller
children make the trip in another vehicle, where they
can get the protection they need.
{CAUTION:
A child restraint cannot be secured properly in
an air-suspension type seat. This is because
an air-suspension seat is designed to move up
and down for an adult passenger. Do not use a
child restraint in an air-suspension seat.If your vehicle is a regular cab model with a static seat
in the right front passenger’s position, or if it has a
bench seat, the child restraint must be secured properly
in the right front passenger’s seat. If your vehicle has
airbags and you need to secure a child restraint in
the right front passenger’s seat, there is a switch on
the instrument panel that you can use to turn off
the passenger’s airbag. SeeAirbag Off Switch on
page 1-56andSecuring a Child Restraint in the Right
Front Seat Position on page 1-44for more on this,
including important safety information.
1-36
CAUTION: (Continued)
If you need to secure a forward-facing child
restraint in the right front static seat or right
front bench 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 has an air-suspension seat in the right
front passenger’s position, do not secure a child restraint
there. Here is why:
{CAUTION:
A child restraint cannot be secured properly in
an air-suspension type seat. This is because
an air-suspension seat is designed to move up
and down for an adult passenger. Do not use a
child restraint in an air-suspension seat.Wherever you install a child restraint, be sure to secure
the child restraint properly.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle — even when no child is in it.
Top Strap
Some child restraints have a top strap, or “top tether,”
which can help hold the child restraint during a
crash. For it to work, a top strap must be properly
anchored to the vehicle. Some child restraints with a
top strap are designed to be used whether or not the top
strap is anchored. Others require that the top strap be
anchored. Also, a national or local law may require
that the top strap be anchored.
If your child restraint top strap must be anchored, then
do not use the restraint in this vehicle, because in
it, a top strap cannot be properly anchored.
1-39
Securing a Child Restraint in the
Right Front Seat Position
Do not use a child restraint with an air suspension seat.
{CAUTION:
A child restraint cannot be secured properly in
an air-suspension type seat. This is because
an air-suspension seat is designed to move up
and down for an adult passenger. Do not use a
child restraint in an air-suspension seat.
There is no top strap anchor in this position. Do not
secure a child seat in this position if a national or local
law requires that the top strap be anchored, or if the
instructions that come with the child restraint say that the
top strap must be anchored. SeeTop Strap on page 1-39
if your child restraint has one.
If your vehicle has a right front passenger airbag,
there is a switch on the instrument panel that you can
use to turn off the right front passenger’s airbag
when you need to secure a child restraint in the right
front passenger’s position. SeeAirbag Off Switch
on page 1-56for more on this, including important safety
information.A rear seat is a safer place to secure a forward-facing
child restraint. Never put a rear-facing child restraint
in the right front passenger’s seat unless the airbag
is off. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the passenger’s
airbag in ates. This is because the back of the
rear-facing child restraint would be very close
to the in ating airbag. Do not use a rear-facing
child restraint in this vehicle unless the
passenger’s airbag has been turned off.
Even though the airbag off switch is designed
to turn off the passenger’s frontal airbag, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is
turned off. We recommend that rear-facing
child restraints be transported in vehicles with
a rear seat that will accommodate a rear-facing
child restraint, whenever possible.
