(1)Pre-Check
a. The new airbag or clock spring shall be checked before being installed.SRS (Supplemental Restraint System)-SRS-General InformationNotice
Use scanner to do adiagnossis of airbag circnit, not to break down.
Keep the removed driver airbag assembly upside down in a clean and dry place.Notice
Keep the removed clock sprint in a clean and dry place.fig.2Installation nutRemoval of steering wheel (see the figure 2)
(1) Remove the installation screws from the middle and remove
the steering wheel.(Disconnect the horn connector)

5-67Notice
When connecting or disconnecting the turn the ignition switch OFF first.
d. Turn the ignition switch ON.
e. Read the diagnostic circuit and see if the other locations than the troubled area of the airbag are normal.
f. Turn the ignition switch OFF.
g. Remove the negative (-) terminal cable from the battery, and protect it with insulating tape for insulation.Notice
Work must be started 60s after the negative (-) terminal cable is disconnected from battery.
(2) Installation of clock spring
Screw up the clock spring clockwise to the end, rotate it counter-
clockwise by 2.5 turns, and align it with the mark (see the figure 3).Notice
If the center of the clock spring cannot be aligned, the steering
wheel will not turn midway, or cause bad performance to the clock
spring circuit, consequently hamper the normal action of the airbag.
(3) Installation of the components of the steering wheel and airbag assembly
a. When the center of the clock spring is aligned, install the components of the steering wheel and airbag
assembly.
b. After being installed, rotate the left and right sides of the steering wheel to position, and make sure there
is no abnormality.

a. Slightly rotate the steering wheel left and right, make sure that there is no abnormality or noise. (Driver
airbag module, clock spring)
b. Turn the ignition switch ON.
c. The warning light goes on within 4s, and then goes out.figure 3SRS (Supplemental Restraint System)-
SRS-General Information b. Connect negative (-) terminal cable of the battery.
c. Connect the diagnostic connector (16 pins).Notice
In case of scrapping an airbag, it shall be noted that the airbag shall be deployed according to the specified
procedures before being scrapped.SRS Air Bag
Warning LightNotice
When installing the components of the steering wheel and
airbag assembly, attention should be given to protect the wire
harness of the clock spring from seizure.
d. The trouble shall be eliminated if the warning light remains on when the ignition switch is turned on or
after it goes out after 4s.

5-68Notice
The circuit resistance of the airbag assembly (squib) cannot be measured even with a designated tester.
Since there is current flowing in the squib, when a tester is involved in measuring the resistance, sometimes
the airbag is unexpectedly deployed in case of static electricity, leading to serious accident.
(2) Check the clock spring
Check the following items, and replace the clock spring if any badness is found.
a. Check the connector and protecting tube for damage and the terminal for distortion.
b. Check the case for damage.
c. Check and see if the joint terminal at the upper end of the clock spring are in conduction with that at the
lower end.
d. A thin probe shall be inserted from the back of the yellow connector of the clock spring.
e. With reference to the figure below, insert thin probes into the current tester to check the conduction of the
terminals.VIII. Key points for scrapping the airbag assembly The airbag shall be deployed according to the following procedures before scrapping the airbag assembly or
a vehicle installed with an airbag.
1. Scrapping of an airbag assembly prior to deploymentNotice
The airbag shall be deployed before being scrapped.
The airbag shall be deployed outside the vehicle before being changed.
The airbag shall be deployed in the vicinity of a smoke detector since smoke will appear when the airbag
is deployed.
When being deployed, the airbag will create much noise. People nearby shall wear noise muffler to close
their ears. Avoid do the job within the residential areas.
Deploy inside a vehicle
1) Park the vehicle in a flat area
2) Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery from
the vehicle.SRS (Supplemental Restraint System)-
SRS-General Information a. Check the cover for pitting, crack and distortion.
b. Check the connector of the wire harness for damage and the terminal for distortion.
c. Check the case of the gas generator for pitting, crack and distortion.
d. Check the installation status of the airbag assembly. 2. Checking
(1) Driver airbag assembly checking
Check the following items and replace the related components of the airbag assembly if any badness is found.
The old components shall be deployed before scrapping.Notice
If there is pitting, crack or distortion, replace the airbag assembly with new one. The old components of
the airbag shall be deployed before scrapping.

5-69Notice
Work must be started 60s after the positive (+) and negative (-) terminal cables are detached from battery.
3) The airbag assembly shall be deployed according to the following procedures.
(1) Driver airbag assembly
a. Remove the knee bolster.
b. Remove the connector (yellow) that connecting the lower end of the clock spring with the wire harness
of the instrument panel (see the figure below).Notice
Remove the connector of the clock spring from the wire harness of the instrument, the connector will be
short circuited automatically, which can avoid the possible serious accident resulted from the deployment of
the diver airbag assembly due to static electricity.
c. Tie two 6m plus wire harnesses for deployment to the
adaptor wire harness of the airbag, and wrap the connecting points
with insulating tape for insulation.The other ends of the wire harness
for deployment are connected to each other (short circuited). Unex-
pected deployment resulted from static electricity shall be prevented.
d. From the yellow connector of the clock spring, lead the
airbag adapter wire harnesses out of the vehicle by means of the wire
harnesses for deployment (see the figure below).
e. To restrain the noise, close all the windows and doors and
put on the vehicle cover.Notice
The glass will likely break up if there is crack. Vehicle covers shall be put on.
f. Try to disconnect at a location far away from the vehicle the connector of the wire harness for deployment
of the driver airbag assembly, connect them with the two terminals of the battery removed from the
vehicle and deploy the airbag (see the figure below).Notice
Make sure there is no man inside or near the vehicle and then
carry out the operations.
After the driver airbag is deployed, the gas generator is of high
temperature. Keep it for 30 minutes until it gets cool for use.
If the driver airbag assembly cannot be deployed, discuss the
problem with the local Geely service station.Deployed
HarnessCovering the car g. The deployed driver airbag assembly shall be scrapped according to the scrapping procedures.
Deploy outside the vehicleNotice
Keep the airbag over 6m away from a obstacle or person and deploy the airbag in an open flat area.
Deployed the airbag outside the vehicle, avoid to do this job in the strong wind. In case of breeze, fire should
be against the wind.SRS (Supplemental Restraint System)-

1) Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery from
the vehicle.Notice
Work must be started 60s after removal of the battery.Notice
When the connector is not connected, the terminals of the driver airbag assembly will be short circuited
automatically, preventing the airbag from being deployed unexpectedly. If the airbag is deployed unexpectedly,
the deployed surface should face up. It should be kept on a flat surface without any other items on it. 2) The airbag assembly shall be deployed according to the following procedures.
Driver airbag assembly
a. Remove the driver airbag assembly from the vehicle.
b. Prepare two 6m plus wire harnesses for deployment, connect
the other two ends to avoid unexpected deployment in case
of static electricity (see the figure below).Notice
The above-mentioned procedures can prevent the unexpected deployment due to static electricity and shall
therefore be performed strictly.Deployed Harness

insulating tape for insulation (see the figure on the right).
f. Pass the deployment wire harness of the driver airbag
assembly through an old tire with rim, and fix upwards the
driver airbag assembly by means of the wire connected to
