Caution!
Do not remove head restraints
except when mounting seat cov­
ers. For removal refer to '' Prac­
tical Hints" , page 99. Whenever
restraints have been removed be
sure to reinstall them before
driving.
Important!
Prior to operating the vehicle, the
driver should adjust the seat
height for proper vision as well as
fore/aft placement and seat back
angle to insure adequate control,
reach, operation, and comfort. The
head restraint should also be
adjusted for proper height.
Both the inside and outside rear
view mirrors should be adjusted
for adequate rearward vision.
Fasten seat belts. Infants and
small children should be seated in
a properly secured restraint
system that complies with U.S
Federal Motor Vehicle Safety
Standard 213 and Canadian
Motor Vehicle Safety Standard
213.1.
All seat, head restraint, and rear
view mirror adjustments as well
as fastening of seat belts should
be done before the vehicle is put
into motion.

Orthopedic Seat Backrest
Some models may be equipped
with orthopedic seats. These
seats have inflatable air cushions
built into the backrest to provide
additional lumbar support. The
amount of cushion height and
curvature may be adjusted after
turning the key in steering lock to
position 1 or 2.
The inflation pressure of the air
cushion can be varied between
position " 0 " = without pressure,
and position " 4 " = maximum
pressure, by changing the
pressure regulator (1) setting.
In addition, the cushion height
may be changed to five different
settings between position " A " =
lowest setting, and " E" = highest
setting, by varying the height
regulator (2) adjustment.
If the engine is turned off, the last
cushion setting is retained in
memory, and automatically ad­
justs the cushion to this setting
when the engine is restarted.
