Section 1 Seats and Restraint Systems
1-1

Horizontal Control:This control adjusts the seat
cushion.
Raise or lower the front of the seat by raising or
lowering the forward edge of the control. Raise or
lower the rear of the seat by raising or lowering the
rear edge of the control.
Move the seat forward or rearward by moving the
whole control toward the front or toward the rear of
the vehicle.
Lower or raise the entire seat cushion by moving the
whole control up or down.
Vertical Control:This control adjusts the seatback.
Move the reclining front seatback rearward or forward by
moving the control toward the rear or the front of the
vehicle. This adjusts the angle of the seatback.
For more information on the reclining seatbacks, see
Reclining Seatbacks on page 1-5.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. SeeMemory
Seat on page 2-82for more information.
Power Lumbar
If your vehicle has power
lumbar adjustment, you
can use it to increase
or decrease lumbar
support in the lower
seatback. The control is
located on the outboard
side of the seat cushion.
To increase support in the lower back area, press
and hold the front of the control. Let go of the
control when the lower seatback reaches the
desired level of support.
To decrease support in the lower back area, press
and hold the rear of the control. Let go of the
control when the lower seatback reaches the
desired level of support.

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
The rear seat head restraints in your vehicle are
adjustable. They work the same as the front seat head
restraints.
Rear Seats
Rear Seat Operation
The rear seat is a 60/40 split rear seat that can be
folded to give you more cargo space and access to the
folding midgate. SeeMidgate on page 2-11for more
information on operation of the folding midgate.
To fold either side of the seat do the following:
1. Push the rear head restraints all the way down.
2. Pull the seat loop
located where the
seatback and seat
cushion meet. The seat
cushion will release and
allow you to tilt it toward
the front of the vehicle.
1-7

3. Grasp the seatback and pull it toward the front of
the vehicle. Push it down until it is at. You may
have to move the front seats forward slightly to
do this.
4. Repeat the procedure for the other side.
To return the seats to the normal position, pull the
seatback up and fold the seat cushion down.
{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.
{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.

To make the belt shorter, pull its free end as shown
until the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap-shoulder belt. If the belt is not long
enough, seeSafety Belt Extender on page 1-28.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt
quickly if you ever had to.
Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
1-23

Lap-Shoulder Belt
All rear seat positions have lap-shoulder belts. Here is
how to wear a lap-shoulder belt properly.
1. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way,
it will lock. If it does, let it go back all the way and
start again.If the belt is not long enough, seeSafety Belt
Extender on page 1-28.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.
1-24

To unlatch the belt, push the button on the buckle.
Rear Safety Belt Comfort Guides for
Children and Small Adults
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.
There is one guide for each passenger position in the
rear seat. Here is how to install a comfort guide and use
the safety belt:
1. Remove the guide from the storage clip on the side
of the rear seatback.
