WARNING
■When adjusting the seat position
●Take care when ad justing the seat
position to ensure that other passen-
gers are not injured by the moving
seat.
●Do not put your hands under the seat
or near the moving parts to avoid
injury.
Fingers or hands may become
jammed in the se at mechanism.
●Make sure to leave enough space
around the feet so they do not get
stuck.
■Seat adjustment
To reduce the risk of sliding under the lap
belt during a collision, do not recline the
seat more than necessary.
If the seat is too reclined, the lap belt may
slide past the hips and apply restraint
forces directly to the abdomen, or your
neck may contact the shoulder belt,
increasing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made while
driving as the seat may unexpectedly
move and cause the driver to lose control
of the vehicle.
■Operating the front passenger’s seat
from the driver’s seat or rear seat
Do not operate the front passenger’s seat
when a passenger is seated in it. In addi-
tion, do not let anyone sit down in the
front passenger’s seat while the seat is
being operated or when the head
restraint is being folded. The front pas-
senger may catch their legs between the
instrument panel and seat, or the head
restraint may interfer e with their head,
resulting in injury.
■When the front passenger’s seat is
folded forward
If the outside rear view mirror is difficult
to see, due to the position of the front
passenger’s seat, mo ve the front passen-
ger’s seat to an appropriate position.
Doing so may lead to mishandling of the
vehicle and cause an accident, resulting
in death or serious injury.
NOTICE

from the driver’s seat or rear seat
Before operating the front passenger’s
seat, make sure that there is no luggage
or any other objects on the seat or in the

being applied, causing damage to the
seat and/or the luggage.
