Toyota Corolla Cross: Precaution

PRECAUTION

GENERAL PRECAUTION

(a) The following conditions may be interpreted as a malfunction even though they are normal operation:

1. An object is placed on the front passenger seat and the system judges that an adult is seated. As the occupant classification system detects and classifies occupants based on weight, the system may detect an object placed on the seat cushion as an adult front passenger depending on its weight.
2. Pressure is applied to the front passenger seat and the system judges that an adult is seated. As the occupant classification system detects and classifies occupants based on weight, the system may detect an adult front passenger if pressure is applied to the seat cushion by hands, etc.
3. Illumination of the passenger airbag ON/OFF indicator does not change immediately after a front passenger is seated or leaves the vehicle. To prevent the classification judgment from changing when a front passenger changes their seating posture, a certain amount of time is required to detect and classify an occupant when the calculated weight changes. Therefore, there will be a time lag between when a front passenger is seated or leaves the vehicle and when the system detects the occupant.

(b) Zero point of the occupant classification sensors may deviate. To ensure sensor accuracy, be sure to perform Zero Point Calibration.
