Entering/exiting the rear seats
Type A  Switch-operated “Front, Fold & Return” Seat
Moving the front seat forward or backward using the switch enables
passengers to enter or exit the rear seats smoothly and easily.
■ When entering/exiting the rear seats
Press the fold switch once. The
seatback of the front seat will fold
and the seat will move forward.
For safety reasons, the seat will be
stopped at a position slightly
behind the most-forward position.
To move the seat further to the
most-forward position, press and
hold the switch again after the seat
is stopped.
■Returning the front seats to the original position
Press the return switch once. The
seatback of the front seat will
return to the upright position and
the seat will move backward.
For safety reasons, if the front seat
was originally positioned close to
the rear seat, the seat will be
stopped at a position slightly in
front of the original position. To
return the seat to its original posi-
tion, press the return switch again.
After the seat is returned to the
original position, pressing and
holding the return switch again
moves the seat further backward.

■Switch-operated “Front, Fold & Return” Seat
●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.

Driving position memory (driver’s seat)∗
Your preferred driving position (the position of the driver's seat, steering
wheel and outside rear view mirrors) can be memorized and recalled with
the touch of a button. It is also possible to set this function to activate auto-
matically when the doors are unlocked.
Three different driving positions can be entered into memory.
■ Entering a position to memory
Switch to IGNITION ON mode.
Adjust the driver’s seat, steering wheel, and outside rear view
mirrors to the desired positions.
Push the “SET” button, then
within 3 seconds push button
“1”, “2” or “3” until the signal
beeps.
If the selected button has
already been preset, the previ-
ously recorded position will be
overwritten.
■Recalling the memorized position
Vehicles with an automatic transmission: Check that the shift lever is
set in P.
Vehicles with a manual transmission: Check that the parking brake is
set.
Switch to IGNITION ON mode.
