Driver-Side Air Bag Module Installation [Two-Step Deployment Control System]

WARNING:

Handling the driver-side air bag module improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the air bag system service warnings and cautions before handling the driver-side air bag module. (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] ). (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM] ).
Due to the adoption of 2-step deployment control in the driver-side air bag module, depending on the impact force, it is possible that inflator No. 2 might not deploy. In such cases, before disposing of the air bag module, make sure to follow the inflator deployment procedures and verify complete deployment of inflators No. 1 and 2.

Point the upper side of the driver-side air bag module towards the steering wheel as shown in the figure.
