GS450h_U (OM30D01U)
CAUTION
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 3 2 )
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to choking or other serious injuries that could
result in death.
If this occurs and the buckle cannot be un fastened, scissors should be used to cut
the belt.
■Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In that case,
the seat belt cannot be used again and must be replaced at your Lexus dealer.
■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 the event of a sudden stop, sudden swerve or accident.
(  P. 3 3 )
Obtain medical advice and wear the seat
belt in the proper way. ( P. 3 2 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants,
extending the shoulder belt completely over
the shoulder and avoidi ng belt contact with
the rounding of the abdominal area.
If the seat belt is not worn properly, not only
the pregnant woman, but also the fetus could
suffer death or serious injury as a result of
sudden braking or a collision.
