381-1. For safe use
WARNING
■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 unfastened, scissors sh ould be used
to cut the belt.
■ 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 t he sensor
from detecting the passenger’s weight properly. As a result, th e seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will c ome on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the cen ter of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of prot ection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or an accident. ( P. 35)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or bu ckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fray ing, and loose
parts. Do not use a damaged seat belt until it is replaced. Dam aged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately conta ct your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious dam age.
● Do not attempt to install, remove, modify, disassemble or dispo se of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling of the pretensioner may prevent it from operating
properly, resulting in death or serious injury.
