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.
• Each seat belt should be used by one person only. Do not use the seat belt
for mor
e than one person at the same time, including children.
• 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 seat -
ing position. The seat belt is most ef fe
ctive 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 personalized seat belt extender
is available from your Lexus dealer free of
charge.

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.
●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 belts, 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
caus
e death or serious injury.
■Using 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.
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.
