CAUTION
●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 pretensioners
●Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, which prevents the sensor from detecting
the passenger's weight properly. As a result, 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.
■Child restraint lock function belt
Do not allow children to play with the child restraint lock function belt.
■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 death or serious 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.
