■Power easy access system (if
equipped)
The driver’ seat and steering wheel
move in accordance with power
switch mode and the driver’ seat
belt condition. ( P.178)
■Jam protection function (vehi-
cles with driving position mem-
ory)
While the driving position is recalled
or the power easy access system is
operating, if an object is stuck
behind the front sea t, the front seat
will stop and then slightly move for-
ward.
When the jam protection function
operates, the seat stops at a posi-
tion other than the set seat position.
Check the seat position.
WARNING
■When adjusting the seat posi-
tion
●Take care when adjusting the
seat position to ensure that
other passengers 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 seat 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 bel t during a colli-
sion, 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.
●Manual seat only: After adjust-
ing the seat, make sure that the
seat is locked in position.
