nPower back door
Observe the following precautions when operating the power back door.
Failure to do so may cause serious injury.
lCheck the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
lIf anyone is in the vicinity, make sure they are safe and let them know that the back
door is about to open or close.
lIf the operating conditions of the power back door are no longer met, a buzzer
may sound and the back door may stop opening or closing. The back door then
has to be operated manually. Take extra care in this situation, as the back door
may move abruptly.
lIf the power back door main switch is turned off while the power back door is
operating, the back door will change to manual operation. In this case, be careful
as the back door may move suddenly.
lOn an incline, the back door may fall after it opens automatically. Make sure the
back door is fully open and secure.
lIn the following situations, the power back door may detect an abnormality and
automatic operation may be stopped. In this case, the back door has to be oper-
ated manually. Take extra care in this situation, as the stopped back door may sud-

Before driving
CAUTION
lDo not attach any accessories other than genuine Lexus parts to the back door.
The power back door may not operate, causing itself to malfunction, or the back
door may fall closed again after it is opened.
lIn cases such as when replacing tires, make sure to turn off the power back door
main switch. Failure to do so may cause the back door to operate unintentionally
if the power back door switch is accidentally touched, resulting in hands and fin-
gers being caught and injured.
nJam protection function (vehicle with a power back door)
Observe the following precautions.
Failure to do so may cause death or serious injury.
lBe careful while the jam protection function is operating. Being hit by the back
door may result in an injury.
lIf anything obstructs the power back door while it is closing, the jam protection
function will cause the back door to automatically operate in the opposite direc-
tion. However, be careful not to jam body parts in the doorframe, as an injury may
result.
lNever use any part of your body to intentionally activate the jam protection func-
tion.
lThe jam protection function may not work if something gets caught just before
the back door fully closes. Be careful not to catch fingers or anything else.
lThe jam protection function may not work depending on the shape of the object
that is caught. Be careful not to catch fingers or anything else.
lThe sensors located on the right and left sides of the power back door detect
obstructions and prevent them from becoming jammed in the door. Some objects
may not be detected depending on their shape or how they are jammed. Be care-
ful not to get fingers or other body parts caught in the back door while it is oper-
ating as this may result in a serious injury.

NOTICE
nBack door damper stays
The back door is equipped with damper stays that hold the back door in place.
Observe the following precautions.
Failure to do so may cause damage to the back door damper stay, resulting in mal-
function.
nTo prevent back door closer malfunction
lDo not apply excessive force to the back door while the back door closer is oper-
ating.
lIf the back door is opened and closed repeatedly in a short amount of time, the
back door closer may stop operating. In this case, manually open the back door
once and wait for a while before attempting to close it again.
nTo prevent damage to the power back door
lMake sure that there is no ice between the back door and frame that would pre-
vent movement of the back door. Operating the power back door when exces-
sive load is present on the back door may cause a malfunction.
lDo not apply excessive force to the back door while the power back door is oper-
ating.
lTake care not to damage the sensors (installed on the right and left edges of the
power back door) with a knife or other sharp object. If the sensor is disconnected,
the power back door will not operate in automatic operation.
lWhen manually closing the back door immediately after the power back door
has been automatically opened fully, some resistance may be felt.
lDo not attach any foreign objects, such as
stickers, plastic sheets, or adhesives to the
damper stay rod.
lDo not touch the damper stay rod with
gloves or other fabric items.
lDo not attach any accessories other than
genuine Lexus parts to the back door.
lDo not place your hand on the damper stay
or apply lateral forces to it.

1-3. Adjustable components (seats, mirrors, steering wheel)
Active head restraints
When the occupant’s lower back
presses against the seatback dur-
ing a rear-end collision, the head
restraint moves slightly forward
and upward to help reduce the risk
of whiplash on the seat occupant.
nThe auto away function for exiting the driver seat
If the seat is already close to the rearmost position, the auto away function may not
operate when the driver exits the vehicle.
nActive head restraints
Even small forces applied to the seatback may cause the head restraint to move.
Pushing up a locked head restraint forcibly may appear the head restraint inner
structure. These do not indicate problems.
nCustomization
The distance that the driver’s seat moves backward during the auto away function
can be changed. (Customizable features →P. 6 2 1 )

nSeat adjustment
lTo 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.
lAdjustments should not be made while driving as the seat may unexpectedly
move and cause the driver to lose control of the vehicle.
