WARNING:

Handling a side air bag improperly can accidentally operate (deploy) the air bag, which may seriously injure you. Read the service warnings/cautions in the appropriate Service Information before handling the front seat (side air bag integrated). For TWO-STEP DEPLOYMENT CONTROL SYSTEM, see AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] and AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] . For STANDARD DEPLOYMENT CONTROL SYSTEM, see AIR BAG SYSTEM SERVICE WARNINGS [STANDARD DEPLOYMENT CONTROL SYSTEM] and AIR BAG SYSTEM SERVICE CAUTIONS [STANDARD DEPLOYMENT CONTROL SYSTEM] .
If the sliding mechanisms on both sides are not locked after assembling the front seat, the front seat will operate accidentally while the vehicle is driven, which could result in serious injury. After assembling the front seat, shake it up and down and verify that the sliding mechanism on the both sides are locked.

NOTE:

If cargo is put on the sensor detection area of the occupancy sensor, the sensor may respond.

Switch the ignition off (LOCK).
