But don't have a seatback reclined if your vehicle
is moving.
CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can't do their job when
you're reclined like this.
The shoulder belt can't do its job because it
won't be against your body. Instead, it will be in
front of you. In a crash you could go into it,
receiving neck or other injuries.
The lap belt can't do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt properly.

1-8 Head Restraints
Head restraints are fixed on some models and adjustable
on others. Slide an adjustable head restraint up or down
so that the top of the restraint is closest to the top of
your ears. This position reduces the chance of a neck
injury in a crash.
The head restraints tilt forward and rearward also.
Seatback Latches
The front seatback folds
forward to let people get
into the back seat or to
access the storage area
behind the seat.
To fold the front seatback forward, move the handle
on the side of the seat rearward and pull the
seatback forward.To return the seatback to the upright position, push the
seatback all the way back until the latch catches. If the
seatback was reclined before being folded forward, it
will return to the reclined position.
CAUTION:
If the seatback isn't 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.
Easy Entry Seat (2-Door Models)
The right front seat of your vehicle makes it easy to get
in and out of the rear seat.

Tilt the right front seatback completely forward and
the whole seat will slide forward.

Move the seatback to its original position after
someone gets into the rear seat area. Then move the
seat rearward until it locks.

CAUTION:
If an easy entry right front seat isn't locked, it
can move. In a sudden stop or crash, the person
sitting there could be injured. After you've used
it, be sure to push rearward on an easy entry seat
to be sure it is locked.

Tilt the seatback completely forward again to
get out.
Rear Seats
Your vehicle has a folding rear seat which lets you fold
the seatbacks down for more cargo space.The rear seat release handles are on the rear of the
seatbacks. Push back on the seatbacks as you pull up on
the handles. The head restraint will automatically fold
out of the way when the seatback is folded down.
To raise the seatbacks, just lift up the seatbacks and push until
they lock in the upright position. Push and pull on the
seatbacks to check that the latches have locked in the upright
position. If they haven't, have them fixed immediately.

reach behind the seats and pull the head restraint up until
it locks into position.On two
-door models with an inside mounted spare tire,
the driver's side rear seat head restraint must be lifted

head restraint will hit the spare tire and prevent the
seatback from properly latching.

have locked in the upright position. If they haven't, have
them fixed immediately.
