AIRBAG SENSOR ASSEMBLY
1. Never reuse the airbag sensor assembly involved in a collision when the airbag has deployed.
2. The connector to the airbag sensor assembly should be connected or disconnected with the sensor mounted on the floor. If the connectors are connected or disconnected while the airbag sensor assembly is not mounted to the floor, it could cause undesired ignition of the SRS.
3. Work must be started after 90 seconds from the time the ignition switch is turned to "LOCK" position and the negative (-) terminal cable is disconnected from the battery even if only loosening the set bolts of the airbag sensor assembly.
