CAUTION
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening
it. Failure to do so may cause the trunk lid to fall closed again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to fall closed again after
it is opened.
●The trunk lid may fall if it is not opened
fully. It is more difficult to open or close
the trunk lid on an incline than on a level
surface, so beware of the trunk lid unex-
pectedly opening or closing by itself.
Make sure that the trunk lid is fully open
and secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.

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

■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.
