Read the safety precautions carefully before servicing any SRS components (see Additional security system (SRS) - general information!
Front driver's airbag
The driver's front airbag is integrated into the hub of the steering wheel and is located below the horn activation button.
1. Disable SRS (see Vehicle speed sensor (VSS) - general information).
2. Set the front wheels in a straight line. After removing the key from the ignition, lock the column.
3. Remove the two mounting screws at the rear of the steering wheel and carefully remove the airbag module assembly with the horn button trim.
4. Disconnect from the module of a pillow of safety electroconducting. Move the removed module to a safe place and place it face up.
When carrying the module, hold it with the faceplate away from you!
5. Installation is carried out in the reverse order. Do not forget to restore the original wiring connection, make sure that the fixing screws are tightened to the required torque.
Front passenger airbag
The passenger pillow is fixed on a cross beam under the dashboard of the car.
1. Disable SRS (see Vehicle speed sensor (VSS) - general information).
2. Remove the glove box (see chapter Body).
3. Using a TORX wrench, remove the mounting bolts and remove the airbag module from the support bracket on the cross member.
4. Disconnect the electrical wiring and remove the module from the car - note that the bottom side of the unit is machined to fit into the bracket holes.
5. Installation is carried out in the reverse order. Make sure that the fixing bolts are tightened to the required torque.
Side airbags
The side airbags are integrated into the outer sides of the front seatbacks.
1. Disable SRS (see Vehicle speed sensor (VSS) - general information).
2. Release the latches and remove the side trim from the seatback.
3. Disconnect the electrical wiring from the module.
4. Give three fixing nuts and remove a pillow from a back of a seat
Manufacturers recommend replacing the self-locking nuts of the airbag modules without fail.
5. Installation is carried out in the reverse order. Connect wiring correctly and tighten nuts to specified torques.
Steering column airbag contact drum
1. Remove the driver's airbag module (see above).
2. Remove the steering wheel (see chapter Suspension and steering). Make sure the front wheels of the car are in a straight line, the ignition key is out of the lock and the steering column is locked.
3. Turn out fixing screws and remove the top and bottom sections of a casing of a steering column (see chapter Suspension and steering). Remove the cover with the identification marking of the key positions from the ignition switch.
4. Use a small screwdriver to release the latch and latch and disconnect the wiring connector from the back of the contact group.
5. Release four back clamps and remove the contact block from the top part of a steering column.
Make sure that both halves of the contact block remain in the central position and are located with the arrows down - if necessary, secure them with tape.
6. Before installing a new or misaligned contact drum, depress the top lock and gently rotate the top of the block counterclockwise until resistance is felt. Now rotate the block 2.5 turns clockwise until the arrows on the center section and outer edge line up. When installing a new unit, first remove the shipping hardware.
7. Install the contact drum on the steering column, making sure that the guide pins fit into the holes in the steering column. Press the block until the latches snap into place.
Be extremely careful - in case of damage to the latches, the unit must be replaced as an assembly!
8. Restore the original wiring connection and secure the connector with the retainer.
9. Establish an overlay with identification marking of positions of a key on the ignition lock. Install the steering column shroud sections and securely tighten their fastening screws (see chapter Suspension and steering).
10. Install the steering wheel (see chapter Suspension and steering).
11. Install the airbag (see above).
Electronic control unit
1. Shut down the system (see Vehicle speed sensor (VSS) - general information).
2. Remove the center console (see chapter Body). On Zafira models also remove the shift lever assembly (see chapter Manual transmission), — the control unit is located under the lever.
3. Disconnect the electrical wiring from the block, give the fixing nuts and remove the block from the car - note that the arrow on top of the block should point forward along the car (due to the asymmetric arrangement of the fasteners, the block has an unambiguous installation position).
4. Installation is carried out in the reverse order. Make sure the fasteners are tightened to the correct torque.
When installing a new control unit, it must be programmed in the conditions of the original Opel car service workshop.
Door impact sensors
The sensors are installed inside the front doors.
1. Shut down the system (see Vehicle speed sensor (VSS) - general information).
2. Remove the inner door upholstery panel (see chapter Body).
3. Bend back the plastic insulating membrane to gain access to the sensor.
4. Remove the fixing screws and remove the sensor from the support bracket. Disconnect the wiring.
5. Installation is carried out in the reverse order. Track reliability of a tightening of fixture.
Front passenger seat occupancy sensor
The sensor is built into the seat cover. The replacement procedure should be entrusted to car service specialists.
