Before removing and refitting components in the airbag system, disconnect the battery negative terminal. To remove the driver's airbag unit, deactivate the airbag system, extract the trim caps over the airbag retaining bolts, undo the two Torx bolts securing the airbag to the steering wheel, withdraw the airbag and disconnect the two wiring connectors, then release the centre locking catch and disconnect the airbag wiring connector from the rear of the airbag unit. Carefully remove the airbag from the steering wheel. Refitting is a reversal of removal, ensuring not to strike the airbag unit during the process and activating the airbag system upon completion. For the airbag rotary connector assembly, first remove the driver's airbag unit, then with the steering in the straight-ahead position, remove the steering wheel and the upper and lower shrouds of the steering column. Disconnect the wiring connectors for the rotary connector and steering angle sensor, undo the screws securing the rotary connector to the steering column, release the lower retaining clips, and withdraw the rotary connector assembly while securing the rotary switch in place with insulating tape. Refitting involves ensuring the rotary connector has not turned, the road wheels are straight, and if uncertain about the rotary connector's position, turning it clockwise to the stop and then anti-clockwise approximately two and a half turns to centralize it. Before refitting the steering column shrouds, ensure the wiring harness is correctly routed, then refit the steering wheel and airbag unit. For the passenger's airbag unit, deactivate the airbag system, remove the glovebox, disconnect the airbag wiring connector, undo the bolts securing the airbag assembly to the facia support rail, release the retaining clips, and carefully withdraw the airbag from the facia. Refitting requires using new bolts to secure the airbag unit and tightening them to the specified torque, avoiding impacts during the process, and activating the airbag system upon completion. The side airbags are located within the front seat back and should not be removed; any issues should be addressed by a Nissan dealer. Similarly, the curtain airbags are located behind the headlining and should not be removed, with any suspected problems also referred to a Nissan dealer.

A driver's and passenger's airbag are fitted as standard on all models. The driver's airbag is located in the steering wheel centre pad, and the passenger's airbag is located above the glovebox in the facia.
