Rear Seats
Rear Seat Operation
The rear seats in your vehicle have levers and
straps used to adjust, remove, and reinstall
the seats. By using the levers and straps in the
correct order, you can easily remove the seats
from the vehicle. If your vehicle has second row
captain chairs with airbags, the seats cannot
be removed.
When you put the seats back in the vehicle, follow
the label on the back of the seat for proper location.
Captain Chairs
Your vehicle has second row captain chairs that
can be adjusted forward or rearward as well
as seatbacks that can be adjusted.
Adjusting the Captain Chairs Forward
or Rearward
There are two manual adjustment bars on each
seat. One is located under the front of the
seat cushion. The other one is located under the
rear of the seat cushion.
Lift either bar to slide the seat forward or rearward.
Release the lever. Push and pull on the seat to
make sure it is locked into place.
Folding or Reclining the Seatbacks
{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.

Removing a Captain Chair
(without a Side Impact Airbag)
If your vehicle has captain chairs with side impact
airbags, the seats cannot be removed.
To remove a captain chair, do the following:
1. Pull the nylon strap behind the seat to release
the rear hooks from the oor pins.2. The seat can then be lifted off the front oor
pins and removed from the vehicle.

Installing a Captain Chair
(without a Side Impact Airbag)
{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 seat that is not locked into place
properly can move around in a collision or
sudden stop. People in the vehicle could
be injured. Be sure to lock the seat into
place properly when installing it.
{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 installing the seat,
always check to be sure that the safety
belts are properly routed and attached,
and are not twisted.
Do not put the seats in so they face rearward
because they will not latch that way. For the
second row, if you want more storage room behind
the seat, adjust the seat by sliding it forward.
Make sure the seatbacks are in the upright
position, the seat belts are on the correct side of
the seats and the seats are in the full rear position
before beginning this procedure.

or the safety belts!
With safety belts, you slow down as the vehicle
does. You get more time to stop. You stop
over more distance, and your strongest bones
take the forces. That is why safety belts
make such good sense.
Questions and Answers About
Safety Belts
Q:Will I be trapped in the vehicle after an
accident if I am wearing a safety belt?
A:Youcouldbe — whether you are wearing a
safety belt or not. But you can unbuckle a
safety belt, even if you are upside down. And
your chance of being conscious during and
after an accident, so youcanunbuckle and get
out, ismuchgreater if you are belted.
Q:If my vehicle has airbags, why should I
have to wear safety belts?
A:Airbags are in many vehicles today and will be
in most of them in the future. But they are
supplemental systems only; so they workwith
safety belts — not instead of them. Every
airbag system ever offered for sale has
required the use of safety belts. Even if you
are in a vehicle that has airbags, you still have
to buckle up to get the most protection. That
is true not only in frontal collisions, but
especially in side and other collisions.

Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely
to be seriously injured if they do not wear
safety belts.
A pregnant woman should wear a lap-shoulder
belt, and the lap portion should be worn as low as
possible, below the rounding, throughout the
pregnancy.The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it
is more likely that the fetus will not be hurt
in a crash. For pregnant women, as for anyone,
the key to making safety belts effective is wearing
them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s
safety belt properly, seeDriver Position on
page 31.
The right front passenger’s safety belt works the
same way as the driver’s safety belt — except
for one thing. If you ever pull the shoulder portion
of the belt out all the way, you will engage the
child restraint locking feature which may turn off
the passenger’s frontal airbag. If this happens, just
let the belt go back all the way and start again.
