■Switch-operated “Front, Fold & Return” Seat
●When the auto return function is on, a buzzer will sound intermittently while the
switch-operated “Front, Fold & Return” seat is in motion.
●If any seat adjustment switch or driving position memory switch is operated
after the seat is moved to the forward and fold position using the “Front, Fold &
Return” seat switch, the seat cannot be returned using the “Front, Fold & Return”
seat switch. Use a switch other than the “Front, Fold & Return” seat switch to
return the seat.
●The switch-operated “Front, Fold & Return” seat cannot operate when:
• A person or item of luggage is on the seat or the seat belt is fastened.
• The vehicle is moving.
●Operation of the Switch-operated “Front, Fold & Return” Seat will stop if:
• The “Front, Fold & Return” seat switch is pressed again.
• Any seat adjustment switch or driving position memory switch is pressed.
• A person enters the seat or an item of luggage is put on the seat (during for-ward movement only).
• The vehicle starts off.
• The seat belt is fastened (during forward movement only).
■When the seatback is fully reclined
Do not use the seatback fold lever to raise the front seat as this may prevent the
seatback from locking in place.
If the seatback will not lock, press and hold the seatback angle switch forward for a
few seconds to change the memorized seat position. Raise the seatback by hand
and check that it locks in position as normal.

CAUTION
■Seat adjustment
Do not recline the seat more than necessary when the vehicle is in motion to reduce
the risk of sliding under the lap belt.
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, increas-
ing the risk of death or serious injury in the event of an accident.
■Retuning the folded seatback to the upright position
Pull the seatback up by hand.
If the seatback angle switch is used to return the seatback, the seat may not be
locked in position, resulting in an accident.
After returning the seat, rock the seat back and forth to ensure that it is securely
locked in position.
■When the vehicle is moving
Do not operate the seatback fold levers.
■Switch-operated “Front, Fold & Return” Seat
●Before operating the switch, ensure that no surrounding passengers or objects
are caught in the seat. Seat operation will not stop automatically, even if some-
thing becomes caught in the seat. This may result in death or serious injury.
●Do not operate the switch while the vehicle is moving.

CAUTION
■While driving
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head restraint, increasing the risk of death or
serious injury to the driver or passenger.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident. The adjustment
mechanism may also be damaged.
■Adjusting the seat position:
●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.
