SYSTEM CALIBRATION (REZEROING)

OPERATION

NOTE: When replacing the occupant detection system, or removing and disassembling the passenger's seat, always perform the system calibration after installing a seat in the vehicle.

1. Park empty vehicle on a level surface.
2. Check the following items to adjust the condition of the vehicle.
- Adjust the seat backrest to be fully upright. (For models with power seats, press the power seat button until the backrest comes to a stop.)
- Adjust the seat slide position all the way back.
(For models with power seats, press the power seat button until the seat slide does not move any further.)
- Do not place anything on the top of the seat cushion.
- Sit on the seat cushion to smooth the seat surface.
- Check that the passenger's seat belt is not inserted into the buckle, not tense or not stuck.
- Check that ambient temperature is in a range from 0 to 40 °C (32 to 104 °F).

3. Turn the ignition switch OFF once, then turn it ON again.

NOTE:
- This operation is performed to reset the occupant detection.
- Do not touch the seat until the system calibration (Rezeroing) is completed. If you have touched the seat even if only once, re-perform the steps from the step 3) again.
