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 on ce, including children.
●Lexus recommends that should be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.
●To achieve a proper seating position, do no t 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.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
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
■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 accident.
●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 vehi cle interior and the extender itself.

CAUTION
■When refueling

slightly lifted away from the fuel filler neck, the automatic shut off function may not
operate, resulting in fuel overflowing from the tank.

Doing so may cause a fire or other incident which may result in death or serious
injury.

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 ar e safer for infants and children than the
front passenger seat. ( P. 1 4 7 )
●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 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 SRS driver’s
airbag may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of collision. Be sure to wear the
seat belt with the seat belt extender.

CAUTION
■Child restraint precautions
●A forward-facing child restraint system may be installed on the front passenger
seat only when it is unavoidable. A child restraint system that requires a top tether
strap should not be used in the front passenger seat since there is no top tether
strap anchor for the front passenger seat. Adjust the seatback as upright as possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of collision.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front, center and rear pillars or roof side rail from
which the SRS side airbags or SRS curtain shield airbags deploy even if the child
is seated in the child restraint system. It is dangerous if the SRS side airbags and
curtain shield airbags inflate, and the imp act could cause death or serious injury
to the child.
●Make sure you have complied with all inst allation instructions provided by the
child restraint manufacturer and that the sy stem is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop or accident.

CAUTION
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the belt
becomes twisted around a child’s neck, it w ill not be possible to pull the belt out
leading to choking or other serious in juries that could result in death.
If this occurs and the buckle cannot be un fastened, scissors should be used to cut
the belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secu red on the seat even if it is not in use.
Do not store the restraint system unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the luggage compartment. This will prevent it from injuring
passengers in the event of a sudden stop or accident.
