Manual Seats
{CAUTION
You can lose control of the
vehicle if you try to adjust a
manual driver’s seat while the

movement could startle and
confuse you, or make you push a
pedal when you do not want to.
Adjust the driver’s seat only when
the vehicle is not moving.To adjust a manual seat:
1. Lift the bar (E) to unlock the seat.
2. Slide the seat to the desired
position and release the bar.
Try to move the seat to be sure it is
locked in place.
Power Seat(s)

rearward by moving the
control (D) forward or rearward.
Move the whole seat up or down
by moving the control up or down.
Tilt the seat by turning the control
forward or rearward.

Reclining Seatbacks
{CAUTION
You can lose control of the vehicle
if you try to adjust the seat while
the vehicle is moving. The sudden
movement could startle and
confuse you, or make you push a
pedal when you do not want to.
Adjust the driver’s seat only when
the vehicle is not moving.
{CAUTION
Sitting in a reclined position when
your vehicle is in motion can be
dangerous. Even if you buckle up,
your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job
because it will not 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.
(Continued)
CAUTION (Continued)
The lap belt cannot 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.
Adjust the reclining seatback by
turning the knob (C). Do not lean on
the seatback while adjusting it.

Page 8 of 356
Head Restraints
The front seats have adjustable
head restraints in the outboard
seating positions.
The rear seats have head rests in
the outboard seating positions.
They are not adjustable.
{CAUTION
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/spinal
injury in a crash. Do not drive
until the head restraints for all
occupants are installed and
adjusted properly.Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant’s
head. This position reduces the
chance of a neck injury in a crash.Pull the head restraint up to raise it.
To lower the head restraint, press
the button, located on the top of
the seatback, and push the
restraint down.
Push down on the head restraint
after the button is released to make
sure that it is locked in place.
The vehicle’s head restraints are not
designed to be removed.
