WARNING
Seat belt pretensioners
■
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
Vehicles with front passenger occu-
●
pant classification system: 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
●
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

is unavoidable, the front seat belts will
retract before the collision. (P.275)
