Installation Procedure
Caution: If the clock spring is not properly aligned,
the steering wheel may not be able to rotate com-
pletely during a turn. Restricted turning ability can
cause the vehicle to crash. Improper alignment of
the clock spring also may make the supplemental
inflatable restraints (SIR) system inoperative, pre-
venting the airbags from deploying during a crash.
Both of these outcomes can result in injury.
Notice: Turning the clock spring more than three turns
clockwise or more than three turns counterclockwise
can damage the spring.
1. Turn the front wheels straight ahead.
2. Install the clock spring with the screws.
Tighten
Tighten the clock spring mounting screws to 3 Nm
(27 lb-in)
Important: The clock spring may come packed in mate-
rial used to prevent damage to the spring during ship-
ping or storage. Avoid installing any of the packing
material with the clock spring.
3. Turn the label of the clock spring clockwise to lock.
4. Turn the label of the clock spring counterclockwise
approximately three turns to the neutral positions with
the front wheels ahead.

AIRBAG MODULE DEPLOYMENT
(IN VEHICLE)
(Left–Hand Drive Shown, Right–Hand
Drive Similar)
Deploy the airbags before disposing of them. This in-
cludes those in a whole vehicle being scrapped.
If the vehicle is still within the warranty period, contact
the Daewoo regional service manager for approval or
special instructions before deploying the airbag mod-
ules.
Caution: Before deploying the airbags, remove all
loose objects from the airbags expansion area.
Caution: Deploy the airbags with the vehicle doors
closed and the side windows open.
Caution: Deploy the airbags only in an evacuated
area. Service personnel who must be present dur-
ing the deployment should be at least 10 meters
(33 feet) in front of the vehicle.
Caution: Do not connect the voltage source until af-
ter having completed all other preparations for the
deployment of the airbags.
Caution: Allow a deployed airbag module to cool
for at least 30 minutes before handling.
Caution: Wear the gloves and the eye protectors
during the disposal process.
Caution: If the deployment fails, disconnect the volt-
age source and wait 5 minutes before approaching
the vehicle.
Deployment Procedure
1. Disconnect both battery cables and place the battery
at least 10 meters (32.8 feet) from the vehicle.
Caution: Wait 1 minute after disconnecting both
battery cables to allow the capacitor inside the
sensing and diagnostic module (SDM) to discharge
before taking any other action. The capacitor sup-
plies the reserve power to deploy the airbags, even
if the battery is disconnected. Unintentional deploy-
ment of the airbags can cause injury.
2. Remove the lower cover from the steering column.
3. At the lower steering column, cut the two wires lead-
ing from the supplemental inflatable restraint (SIR)
harness to the clock spring.
4. Strip 13 mm (0.5 inch) of insulation from the ends of
the wires leading to the clock spring.
5. Use two additional wires, each at least 10 meters
(33 feet) long, to reach from the deployment battery
to the airbag module.
6. Strip 13 mm (0.5 inch) of insulation from the ends of
these two additional wires.
7. Twist the two wires together at one end.

8. Place the twisted ends of the two wires near the de-
ployment battery. Do not connect the wires to the
battery at this time.
9. Using the free ends of the 10 meters (33 feet) wires
leading to the clock spring, make two splices, one at
each wire from the airbag module.
10. Wrap the splices with insulating tape.
11. Now that the free ends of the 10 meters (33 feet)
wires are spliced to the airbag module wires, and the
ends that are twisted together are near the deploy-
ment battery, clear the area.
12. Untwist the wires that are near the deployment
battery.
13. Touch one wire to the positive battery terminal and
touch the other wire to the negative battery terminal.
The airbag will deploy.
14. Repeat the procedure for the passenger airbag,
cutting the wires to the passenger airbag module
instead of the wires leading to the clock spring.
15. Strip 13 mm (0.5 inch) of insulation from the ends of
the wires leading to the passenger airbag module.
16. Use two additional wires, each at least 10 meters
(33 feet) long, to reach from the deployment battery
to the passenger airbag module.
17. Strip 13 mm (0.5 inch) of insulation from the ends of
these two additional wires.
18. Twist the two wires together at one end.
19. Place the twisted ends of the two wires near the de-
ployment battery. Do not connect the wires to the
battery at this time.
20. Using the free ends of the 10 meter (33 feet) wires to
the passenger airbag module, make two splices,
one at each wire from the airbag module.
21. Wrap the splices with insulating tape.
22. Now that the free ends of the 10 meters (33 feet)
wires are spliced to the passenger airbag module
wires, and the ends that are twisted together are
near the deployment battery, clear the area.
23. Untwist the wires that are near the deployment
battery.
24. Touch one wire to the positive battery terminal and
touch the other wire to the negative battery terminal.
The passenger airbag will deploy.
25. Using the proper precautions, dispose of the
deployed airbag. Refer to “Deployed Airbag Module
Disposal Procedure” in this section.
