WARNING
■Do not allow an occupant in the front passenger’s seat to sit with a
posture which makes it difficult fo r the front passenger occupant clas-
sification sensor to detect the occupant correctly
Sitting in the front passenger’s seat with a posture which makes it difficult
for the front passenger occupant classification sensor to detect the occu-
pant correctly is dangerous. If the front passenger occupant classification
sensor cannot detect the occupant sitting on the front passenger’s seat cor-
rectly, the front passenger front and side air bags and pretensioner system
may not operate (deploy) or they may operate (deploy) accidentally. The
front passenger will not have the supplementary protection of the air bags or
the accidental operation (deployment) of the air bags could result in serious
injury or death. Under the following conditions, the front passenger occ\
u-
pant classification sensor cannot detect a passenger sitting on the front
passenger’s seat correctly and the deployment/non-deployment of the air
bags cannot be controlled as indicated in the front passenger air bag deac-
tivation indicator light on/off condition chart. For example:
● A front passenger is seated as shown in the following figure:
● A rear passenger pushes up on the front passenger seat with their feet.
● Luggage or other items placed under the front passenger seat or between
the front passenger seat and driver seat that push up the front passenger
seat bottom.
● An object, such as a seat cushion, is put on the front passenger’s seat or
between the passenger’s back and the seatback.
