NOTICE:

  • Temporarily tighten the 2 bolts in the order of (A), (B) and then fully tighten the 3 bolts in the order of (C), (A) and (B).
  • If the airbag sensor assembly has been dropped, or there are any cracks, dents or other defects in the case or connector, replace it with a new one.
  • When installing the airbag sensor assembly, make sure that the SRS wiring does not interfere with or is not pinched between other parts.
  • When the ignition switch (for Gasoline Model) or power switch (for HV Model) is first turned to on (IG) after the airbag sensor assembly has been replaced, make sure that no one is in the vehicle.

(d) Temporarily connect the connector and then move the lock lever in the direction indicated by the arrow to securely connect the connectors.
