CAUTION
Observe the following precautions to reduce the risk of injury in the event of sudden
braking or an accident. Failing to do so may cause death or serious injury.
■Wearing a seat belt
●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.
●Lexus recommends that children should be seated in the rear seat 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.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoul-
der. The belt should be kept away from yo ur 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 a collision. ( P. 6 7 )
■Seat belt pretensioners
●Do not place anything, such as a cushion, on the front passenger’s seat. Doing so
will disperse the passenger’s weight, wh ich prevents the sensor from detecting
the passenger’s weight properly. As a resu lt, the seat belt pretensioner for the
front passenger’s seat may not activate in the event of a collision.
●If the pretensioner has activated, the seat belt becomes locked: it cannot be fur-
ther extended, nor will it return to the stowed position. The seat belt cannot be
used again and must be replaced at your Lexus dealer.

CAUTION
■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.
■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.

CAUTION
■While driving
●Do not adjust the position of the driver’s seat.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback. 
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head re straint, increasing the risk of death or
serious injury to the driver or passenger.
●Do not place anything under the front seats. 
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident. The adjustment
mechanism may also be damaged.
■Adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are
not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury. 
Fingers or hands may become jammed in the seat mechanism.
