WARNING:

• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes

or more.

• Before disconnecting the air bag sensor unit harness connector, be sure to disconnect the each har-

ness connector of the air bag module and pre-tensioner seat belt to prevent air bag deployment by
