Front seats

WARNING

Never adjust the seat while driv-

ing to avoid loss of vehicle con-
trol and personal injury.

Before adjusting the seat, make

sure the hands and feet of rear
seat passengers and cargo are
clear of the adjusting mechan-
ism.

After adjusting the seat, move it

back and forth to make sure it is
securely locked. If the seat is not
securely locked, it may move or
the seatbelt may not operate
properly.

Do not put objects under the front

seats. They may interfere with
front seat locking and cause an
accident.

Seatbelts provide maximum re-

straint when the occupant sits
well back and upright in the seat.
To reduce the risk of sliding
under the seatbelt in a collision,
the front seatbacks should be
always used in the upright posi-
tion while the vehicle is running.
If the front seatbacks are not

used in the upright position in a
collision, the risk of sliding under
the lap belt and of the lap belt
sliding up over the abdomen will
increase, and both can result in
serious internal injury or death.

The SRS airbags deploy with

considerable speed and force.
Occupants who are out of proper
position when the SRS airbag
deploys could suffer very serious
injuries. Because the SRS airbag
needs enough space for deploy-
ment, the driver should always sit
upright and well back in the seat
as far from the steering wheel as
practical while still maintaining
full vehicle control and the front
passenger should move the seat
as far back as possible and sit
upright and well back in the seat.

WARNING

Place children in the rear seat prop-
erly restrained at all times. The SRS
airbag deploys with considerable
speed and force and can injure or
even kill children, especially if they
are not restrained or improperly
restrained. Because children are
lighter and weaker than adults, their
risk of being injured from deploy-
ment is greater. For that reason, we
strongly recommend that ALL chil-
dren (including those in child seats
and those that have outgrown child
restraint devices) sit in the REAR
seat properly restrained at all times
in a child restraint device or in a
seatbelt, whichever is appropriate

for the child’s age, height and
weight. Secure ALL types of child
restraint devices (including forward
facing child seat) in the REAR seats
at all times.

NEVER INSTALL A CHILD SEAT IN
THE FRONT SEAT. DOING SO RISKS
SERIOUS INJURY OR DEATH TO
THE CHILD BY PLACING THE
CHILD’S HEAD TOO CLOSE TO
THE SRS AIRBAG.

According to accident statistics,
children are safer when properly
restrained in the rear seating posi-
tions than in the front seating posi-
tions. For instructions and precau-
tions concerning child restraint sys-
tems, refer to “Child restraint sys-
tems” F1-21.

WARNING

To prevent the passenger from slid-
ing under the seatbelt in the event of
a collision, observe the following
precautions:

Keep the seatback in the upright

position while the vehicle is in
motion.

Do not place objects such as

cushions between the passenger
and the seatback.

Otherwise, the risk of sliding under
the lap belt and of the lap belt sliding
up over the abdomen will increase,
and both can result in serious inter-
nal injury or death.

WARNING

Do not let rear passengers rest their
feet between the front seatback and
seat cushion. Doing so may lead to
improper operation of the following
systems and could result in serious
injury.

Head restraint adjustment

WARNING

Never drive the vehicle with the

head restraints removed because
they are designed to reduce the
risk of serious neck injury in the
event that the vehicle is struck
from the rear. Also, never install
the head restraints the opposite
way round. Doing so will prevent
the head restraints from function-

ing as intended. Therefore, when
you remove the head restraints,
you must reinstall all head re-
straints correctly to protect vehi-
cle occupants.

All occupants, including the dri-

ver, should not operate a vehicle
or sit in a vehicle’s seat until the
head restraints are placed in their
proper positions in order to mini-
mize the risk of neck injury in the
event of a crash.

The front seat head restraints are

designed to be installed into the
front seats only. The rear seat
head restraints are designed to
be installed into the rear seats
only. Do not attempt to install the
front seat head restraints into the
rear seats, or the rear seat head
restraints into the front seats.

NOTE

It is possible to adjust the angle of the
front seat head restraints only. When
installing the front seat head restraints,
make sure that the angle of the head
restraints can be adjusted.

Both the driver’s seat and front passen-
ger’s seat are equipped with head re-
straints. Both head restraints are adjusta-

ble in the following ways.

Head restraint height adjustment

Head restraint

Release button

To raise:
Pull the head restraint up.
To lower:
Push the head restraint down while press-
ing the release button on the top of the
seatback.
To remove:
While pressing the release button, pull out
the head restraint.
To install:
Install the head restraint into the holes that
are located on the top of the seatback until
the head restraint locks. Press and hold

the release button to lower the head
restraint.

Adjust each head restraint so that the
center of the head restraint is closest to the
top of the occupant’s ears.

NOTE

When the head restraint will not move
in or out due to insufficient clearance
between the head restraint and the roof,
tilt the seat and then perform the
installation and removal tasks.

Head restraint angle adjustment

It is possible to adjust the angle of the head
restraint in several steps. While maintain-
ing a suitable driving posture, adjust the
head restraint to a position where the back
of your head is as close to the head
restraint as possible.

To tilt:
Tilt the head restraint by hand to the
preferred position. A click will be audible
when the head restraint is locked.
To return:
Tilt the head restraint once as far forward
as it can go. The head restraint will
automatically return to the fully upright
position. Then, adjust the head restraint
again to the preferred angle.
