For your protection, drive only with properly
positioned head restraints.
Adjust head restraint to support the back of
the head approximately at ear level.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iThe front passenger seat head restraint
automatically lowers after a few sec-
onds when the front passenger seat is
not occupied. This improves the driv-
er’s outward view as well as the for-
ward view from the rear passenger
compartment.
When the front passenger seat is occu-
pied again, the front passenger seat
head restraint returns to the last set
position within a few seconds.
If the front passenger seat was moved
fore or aft while not being occupied,
the front passenger seat head restraint
returns to a position that corresponds
best with the seat’s axial position when
the seat is occupied again.

ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
