Before driving
CAUTION
■Reclining 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 during an accident, the lap belt may slide past the hips and
apply restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury.
■When the seatback is folded
Do not sit on or place anything on the seatback while driving.
■When returning the seatbacks to their original position
Observe the following precautions. Failure to do so may result in death or serious
injury.
●Be careful not to get your hands or feet pinched in the seat.
●Make sure the seats are securely locked. Failure to do so will prevent the seat belt
from operating properly.
●Check that the seat belts are not twisted or caught under the seat.
●Arrange the seat belts in the proper positions for ready use.
■When folding up the third seats
Fix the seats securely by adjusting the length of the holding strap. Failure to do so
may cause death or serious injury in the event of an accident or sudden braking.
■When removing or reinstalling the third seats
Observe the following precautions to prevent personal injury:
●Do not remove or reinstall the seats while the vehicle is moving.
●Do not leave the removed seat loose in the vehicle.
●Be careful not to get your hands or feet pinched in the seats.
●Be careful not to hit a person with the removed seat or drop it on yourself.
●Do not sit on or place anything on the removed seat.
●Install each seat in the same position from which it was removed. Failure to do so
will prevent third seat occupants from using the seat belts properly.

Before driving
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (→P. 4 9 )
■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriately for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt. ( →P. 9 5 )
●When the child becomes large enough to properly wear the vehicle’s seat belt,
follow the instructions on P. 49 regarding seat belt usage.
■Replacing the belt after the pretensioner has been activated
The seat belts cannot be used if a pretensioner has activated. After an accident,
have your Lexus dealer inspect the pretensioners and replace them, if necessary.
■Seat belt extender Obtain medical advice and wear the seat belt
in the proper way. (
→P. 4 9 )
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.
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
■When using the third center seat belt
■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 serious 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.
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 vehicle interior and the extender itself.
Do not use the third center seat belt with
either buckle released. Fastening only one of
the buckles may result in death or serious
injury in case of sudden braking or a collision.

on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver’s seat position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc. Front passenger airbag

Before driving
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. 9 5 )
●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.

■When the child restraint system is not in use
Leave the child restraint system properly secured on the seat. Do not store the
restraint loosely on a passenger seat or in the luggage compartment.
■Selecting an appropriate child restraint system
Get an appropriate child restraint system for the child. If a child is too large for a
child restraint system, sit the child on a rear seat and use the vehicle’s seat belt.
