Pre-collision seat belts (front seats of vehicles with pre-collision system)When the pre-collision sensor detects an obstacle and determines that a
collision is unavoidable, the seat belt s lessen collision injury by retracting
the slack in the front seat belts befo re the collision, thus restraining the
driver and passenger at an earlier stage. 
The seat belts will also operate in the event of sudden braking. ( P. 1 6 9 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudd en stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend, and
you can move around fully.
■Automatic 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. 8 9 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. ( P. 4 0 )
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 rounding of the
abdominal area.
If the seat belt is not worn properly, not only a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking or a collision.

Before driving
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 4 0 )
■Child seat belt usage
The seat belts of your vehicle were princi pally designed for persons of adult size.
●Use a child restraint system appropriately for the child, until the child become
large enough to properly wear the vehicle's seat belt. ( P. 8 2 )
●When the child becomes large enough to properly wear the vehicle's seat belt,
follow the instructions on P. 40 regarding seat belt usage.
■Replacing the belt after the pretensioner has been activated
The seat belts cannot be used if a preten sioner has activated. After an accident,
have your Lexus dealer inspect the pretensioners and replace them, if necessary.
■Seat belt extender
If your seat belts cannot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sud-
den braking or an accident. Failing to do so may cause death or serious injury.
●Ensure that all passengers wear a seat belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at the same time, including children.
●Children should be seated in the rear se at and always use a seat belt and/or an
appropriate child restraint system.
●Do not recline the seat any more than necessary to achieve a proper seating
position. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from injury.
●Ensure that the belt and tab are locked and the belt is not twisted. If the seat belt
does not function correctly, immediately contact your Lexus dealer.
●Replace the seat assembly, including the belt s, if your vehicle has been involved in
a serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify , disassemble or dispose of a seat belt.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may cause it to activate or operate improperly and may
cause death or serious injury.

CAUTION
■Using a seat belt extender
●Do not wear the seat belt extender, if you can fasten the seat belt without the
extender.
●Do not use the seat belt extender when installing a child restraint system, because
the belt will not securely hold the child restraint system, increasing the risk of
death or injury in the event of a collision.
●The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.
■Precaution for pre-collision seat belts
Do not rely solely on the pre-collision system to avoid accidents. Always pay atten-
tion to the surrounding conditions , and drive safely and responsibly.
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender,
not on the seat belt.
This helps prevent damage to the vehi cle interior and the extender itself.

CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are the safest for infants and children.
(  P. 8 2 )
●If the seat belt extender has been con-
nected to the driver's seat belt buckle but
the seat belt extender has not also been
fastened to the latch plate of the driver's
seat belt, the SRS driver's airbag system
will judge that the driver is wearing the seat
belt even though the seat belt has not been
connected. In this case, the driver's airbag
may not activate correctly in a collision,
resulting in death or serious injury in the
event of collision. Be sure to wear the seat
belt with the seat belt extender.

■System malfunction
*
1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*
2: In the event the front passenger does not wear a seat belt.
*3: When a large child who has outgrown a child restraint system sits in the front passenger seat, the sys tem may recognize him/her as an
adult depending on his/her physique and posture.
*
4: Never install a rear-facing child restraint system on the front passen- ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. 
( P. 8 2 )
*
5: In case the indicator is not illum inated, consult this manual as for
installing the child restraint system properly. ( P. 8 5 )

■Front passenger occupant classification system precautions
●If an adult sits in the front passenger se at, the “AIRBAG ON” indicator light is illu-
iminated. If the “AIRBAG OFF” indicator is illuminated, ask th e passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIRBAG OFF” indicator still remain illuminated, either ask the pas-
senger to move to the rear seat, or if th at is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forw ard-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. ( P. 8 5 )
●Do not remove the front seat.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.
