WARNING
●Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and receive
neck or other serious injuries. You
could also slide under the lap belt and
receive serious internal injuries.●For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back in the
seat with both feet on the floor and
adjust the seat properly. See “Precau-
tions on seat belt usage” later in this
section.
●After adjustment, gently rock in the seat
to make sure it is securely locked.
●Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.●The seatback should not be reclined
any more than needed for comfort. Seat
belts are most effective when the pas-
senger sits well back and straight up in
the seat. If the seatback is reclined, the
risk of sliding under the lap belt and
being injured is increased.
CAUTION
When adjusting the seat positions, be
sure not to contact any moving parts to
avoid possible injuries and/or damage.

slide the seat forward or backward to the desired
position. Release the bar to lock the seat in
position.

To recline the seatback, pull the lever up and lean
back. To bring the seatback forward, pull the lever
up and lean your body forward. Release the lever
to lock the seatback in position.
The reclining feature allows adjustment of the
seatback for occupants of different sizes for
added comfort and to help obtain proper seat
belt fit. See “Precautions on seat belt usage” later
in this section. Also, the seatback can be reclined
to allow occupants to rest when the vehicle is
stopped and the shift selector (CVT) is in P (Park)
or the manual transmission is in N (Neutral) with
the parking brake applied.
Seat lifter (if so equipped for driver’s
seat)
Pull up or push down the adjusting lever to adjust
the seat height until the desired position is

Interior trunk access (if so equipped)
The trunk can be accessed from the rear seat for
loading and unloading, as shown.
1. Stow outboard seat belts with clip before
folding rear seatbacks.
When folding the passenger’s side rear seat-
back, first disconnect and stow the center seat
belt. See “Stowing the rear center seat belt” later
in this section.2. Pull up on the strap
Alocated on the top
outboard side of the seat to be folded.
3. Fold seatback down.
WARNING
●Never allow anyone to ride in the cargo
area or on the rear seat when it is in the
fold-down position. Use of these areas
by passengers without proper restraints
could result in serious injury in an acci-
dent or sudden stop.●Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
●When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched posi-
tion. If they are not completely secured,
passengers may be injured in an acci-
dent or sudden stop.
●Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.

FRONT-SEAT ACTIVE HEAD
RESTRAINTS
WARNING
●Always adjust the head restraints prop-
erly as specified in this section. Failure
to do so can reduce the effectiveness of
the Active Head Restraint.
●Active Head Restraints are designed to
supplement other safety systems. Al-
ways wear seat belts. No system can
prevent all injuries in any accident.●Do not attach anything to the head re-
straint stalks. Doing so could impair
Active Head Restraint function.
The Active Head Restraint moves forward utiliz-
ing the force that the seatback receives from the
occupant in a rear-end collision. The movement
of the head restraint helps support the occu-
pant’s head by reducing its backward movement
and helping absorb some of the forces that may
lead to whiplash-type injuries.
Active Head Restraints are effective for collisions
at low to medium speeds in which it is said that
whiplash injuries occur most.
Active Head Restraints operate only in certain
rear-end collisions. After the collision, the head
restraints return to their original positions.
Properly adjust the Active Head Restraints as
described in this section.

erly as they may provide significant pro-
tection against injury in an accident. Do
not remove them. Check the adjustment

with the center of your ears.
