2008 GEELY MK Workshop Manual

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

harness c. Touch the body of the vehicle with hands for static electricity elimination.
d. Cut off the wire harnesses of the driver airbag assembly and
connect them with the two wire harnesses for deployment,
and make sure to wrap up the connecting location with
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
the bolts, etc (see the figure on the right). e. Install the unused bolts to the inside bolt of the driver airbag assembly,and tie a thick metal wire securing
the wheel rim.5-70SRS (Supplemental Restraint System)-

Deployed HarnessDeployed Harness h. 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 with the two terminals of the
battery removed from the vehicle and deploy the airbag
(see the figure on the right). g. Put three used tires without hubs onto the tire used to fix the
driver airbag assembly (see the figure on the right).
i. The deployed driver airbag assembly shall be scrapped according to the scrapping procedures.Notice
Make sure to deploy the driver airbag assembly when there is no person close by.
After the driver airbag is deployed, the gas generator is of high temperature. Keep it for over 30 minutes
until it gets cool for use.
If the driver airbag can't be deployed, please contact the Geely service station for help.5-71SRS (Supplemental Restraint System)-

compressor, condenser and evaporator etc, it adsorbs heat in the air through circulation of refrigerant, so as to
reduce air temperature in car body and eliminate water vapour in air, to achieve the purpose of temperature drop
and dehumidification. Heating system mainly consists of heat exchanger and heater unit. It utilizes heat of engine
cooling water to heat air via heat exchanger, so as to achieve the purpose of heating. Regulation and control of
temperature, humidity and flow rate of air in car body is realized via heating and refrigeration systems separately
or jointly.
For parameters of refrigerating system, see the table:

General Information

5-73Precautions:1. Don't operate refrigerant in confined space or near open fire.
2. Always wear eyeglass.
3. Be careful don't let liquid refrigerant contact your eyes and skin,
if liquid refrigerant contacts your eye or skin.
(a) Please wash with fresh water.
Warning:
Don't knead your eyes or scrub your skin
(b) Apply soft petroleum ointment on your skin.
(c) See doctor or go to hospital immediately for specialized
treatment.
4. Don't heat container or put it near open fire.
5. Be careful not to fall off, object should not touch container.
6. If there is no sufficient refrigerant in refrigerating system, don't
operate the compressor.
If there is no sufficient refrigerant in the system, insufficient oil
lubrication might cause burning out of compressor. Be careful to
avoid occurrence of such things.
7. When compressor runs, don't turn on pressure gauge high-pressure
valve.
If high-pressure valve is turned on, refrigerant will flow in reverse
direction, and cause bursting of refrigerant tank, so only low
pressure valve may be turned on or off.
8. Be careful to avoid excess refrigerant
Excess refrigerant will result in poor refrigerating capacity, worse
fuel economical efficiency, engine overheat etc problems.Symptom

part according to priority, replace components if required.
