with a head restraint that can be adjusted ver-
tically to suit the height of the passenger. The
upper edge of the head restraint should be at
least on a level with the upper-most point of the
seat occupant's ear (see illustration).

The center rear seat head restraint should
only be in its lowest position when this seat
is NOT occupied. When the center position
is occupied, the head restraint should be
correctly adjusted to the passenger’s
height. The upper edge of the head restraint
should be at least on a level with the upper-
most point of the seat occupant's ear.

To raise: Slide the head restraint up to the
desired height.

To lower: Press the catch at the base of the
right support and press the head restraint
down.

To remove: Pull the head restraint up far as
possible. Press the catch at the base of the
right support and pull the head restraint out
of the its holders.

be put properly back in place and it must
lock (click) into one of the available adjust-
ment positions before the seat is occupied.

Press the center head restraint down com-
pletely or remove it.
4. Place the head restraints in the plastic
tubes, which are now accessible on the
under side of the seat cushions.
WARNING
The center rear seat head restraint should
only be in its lowest position when this seat
is NOT occupied. When the center position
is occupied, the head restraint should be
correctly adjusted to the passenger’s
height. The upper edge of the head restraint
should be at least on a level with the upper-
most point of the seat occupant's ear.
NOTE
When folding down the rear seat backrests,
remove the plug in the rear 12-volt socket to
help avoid marks in the upholstery.
WARNING
•The red lock indicator is VISIBLE when
the backrest is NOT locked in position
and hidden when the backrest is cor-
rectly locked in place. When the back-
rest is in the upright position, it must
always be correctly locked in place.
•When the rear seat is folded down, do
not place heavy objects against the
backs of the front seats. This places a
severe strain on the folded down back-
rest of the rear seat. Be sure to secure
cargo.
•Cargo must not be stacked higher than
the top of seat backs. This will reduce
the possibility of luggage, etc. becom-
ing projectiles during sudden maneu-
vers, rapid braking or an accident.
