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)
Pre-collision seat belts (front seats of vehicles with pre-collision system)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt, thus enhancing the effectiveness
of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. (→P. 2 4 0 )
nEmergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward too quickly. To allow the belt to extend, retract the belt and then
pull it slowly.
nAutomatic locking retractor (ALR)
When a passenger's shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is
used to hold the child restraint system (CRS) firmly. To free the belt again, fully
retract the belt and then pull the belt out once more. (→P. 1 3 1 )
nPregnant women
Obtain medical advice and wear the seat belt
in the proper way. (→P. 7 5 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.
Avoid belt contact over the round part of the
abdominal area.
If the seat belt is not worn properly, not only
the pregnant woman, but also the fetus could
suffer death or serious injury as a result of
sudden braking or a collision.

CAUTION
nWearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sudden
braking, sudden swerving or an accident.
Failing to do so may cause death or serious injury.
lEnsure that all passengers wear a seat belt.
lAlways wear a seat belt properly.
lEach seat belt should be used by one person only. Do not use a seat belt for more
than one person at once, including children.
lLexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.
lTo achieve a proper seating position, do not recline the seat more than necessary.
The seat belt is most effective when the occupants are sitting up straight and well
back in the seats.
lDo not wear the shoulder belt under your arm.
lAlways wear your seat belt low and snug across your hips.
nAdjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoul-
der. The belt should be kept away from your neck, but not falling off your shoulder.
Failure to do so could reduce the amount of protection in an accident and cause
death or serious injuries in the event of a sudden stop, sudden swerve or accident.
(→P. 76 )
nSeat belt pretensioners
lDo not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, which prevents the sensor from detecting
the passenger's weight properly. As a result, the seat belt pretensioner for the
front passenger's seat may not activate in the event of a collision.
lIf the pretensioner has activated, the SRS warning light will come on. In that case,
the seat belt cannot be used again and must be replaced at your Lexus dealer.

1-7. Safety information
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
nIf the SRS airbags deploy (inflate)
lBruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
lA loud noise and white powder will be emitted.
lParts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, and parts of the front and rear pillars, and roof side rails, may
be hot for several minutes. The airbag itself may also be hot.
lThe windshield may crack.
lFor Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. (→P. 4 3 6 )
