2696Try 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).
7The deployed driver airbag assembly shall be scrapped according to the scrapping procedures.
(3) Deploy outside the vehicle
NOTICE:
Keep the airbag over 6m away from a obstacle or person and deploy the airbag in an open flat area.
1Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery
from the vehicle.
2The airbag assembly shall be deployed according to the following procedures.
(4) Driver airbag assembly
1Remove the driver airbag assembly from the vehicle.Vehicle CoverWire Harness
for DeploymentNOTICE
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.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.

276Section 2 ABS System CheckI. DTC Problem Inspection TableNote: If the Battery is excessively discharged, the motor will not be driven, therefore you must
check that the battery voltage is normal before performing the motor driving test. The vehicle
must be stationary during the test. 1 DTC 01276 Like ly Causes

292Section 3 Removal and InstallationI.Precautions for Removal1. Use the scan meter to locate the fault causes before proceeding to service.
2. wipe the surface clean with the cleaning agent without mineral oil before service; be careful to keep it
clean during service, only the lint-free cloth can be used to wipe the removed parts.
3. Only the original spare part can be used, and the package of the new spare part shall not be removed until
the installation.
4. Return liquid pump motor and the HCU is a type of integral structure and can not be separated.
5. When the system is opened, do not use compressed air or move the vehicle.
6. Use proper plug to clog each hydraulic outlet as soon as the ABS assembly is removed.
7. Remove other components that may interfere.
8. Please use the DOT 4 brake fluid, do not use the mineral oil.
9. Use the brake fluid to immerse the seal and the O ring, do not use the engine oil or brake grease.
10. After service, check the regular brake system and ABS brake function for normal and reliable operation.
11. Check all hydraulic pipe union for leakage.II. HECU Removal1. Turn off the ignition switch and disconnect the battery negative ground cable.
2. Remove the wire connector from the ABS HECU assembly.
3. Depress the brake pedal >60mm and hold it with the pedal retainer to close the master cylinder center
valve so that the brake fluid will not flow out from the outlet when the system is opened.
4. Put a clean cushion under the hydraulic regulator.
5. Remove the brake pipe (A, B) on the HCU connected to the master cylinder and place the mark, then
use a plug to clog the outlet immediately.
6. Remove the brake fluid pipe(1-4) leading to the wheels, then use a plug to clog the outlet immediately.
7. Remove the nut attaching the HECU to the bracket.

304Section 4 Service Caution & NoticeI. Service CautionRefrigerant Treatment
•During the treatment, the operator shall be careful not to inhale A/C refrigerant or lubricant vapor. Long-
term exposure to the A/C environment will cause the operator's eye, nose and throat liable to stimulation.
In addition, based on the consideration on the environment influence, when discharging the HFC-134a
from the A/C system, we suggest using the recyclable and rechargeable devices. If sudden system fault
occurs, it is recommended to place the device on a ventilated place before starting service.
•For HFC-134a service equipment, it is recommended not to perform the pressurization check or leakage
inspection. If these mixture combust, it may result in severe human injury or property loss.
•Please be noticed not to let the refrigerant leak near the spark or other hot objects. If the refrigerant gas
contacts the spark or similar heat source (e.g. cigarette or heater), it may generate poisonous gas. The
refrigerant is extremely liable to leakage during the transportation. In this case, please eliminate or remove
the heat source mentioned above and keep good ventilation.
•It is very dangerous to handle the liquid refrigerant. Only a drop of refrigerant can result in local frostbite
on skin if dropped on the skin of the operator. Therefore, it is specified that the operator shall always
wear glove and eye protection during the handling of the liquid refrigerant. If liquid refrigerant gets in
your eyes or on your skin, Wash the area with much cool water. Go immediately to hospital for professional
treatment.
Refrigerant Preservation
• Refrigerant preservation container is a high pressure resistant equipment. If it is put in hot treatment, the
explosion may arise, and the resulting metal fragments and the splashed liquid refrigerant will result in
severe human injury. It is recommended to preserve the refrigerant below 40°C.II. Service NoticeInsufficient Refrigerant Handling
•If the refrigerant is founded to be insufficient during the fault diagnosis, it is recommended not to add
refrigerant because of the following facts: the pressure readings indicated by different pressure gauge
are different, thus you will be unable to determine the exact amount of the refrigerant to be added, and
excessive or insufficient refrigerant may cause a series of chained negative effects such as damaged
refrigerant circulation parts or deteriorated refrigeration effect. Therefore, if the refrigerant is found to
be insufficient, it is recommended to drain the refrigerant from the refrigerant circulation pipeline and fill
specified amount of the refrigerant.
Compressor Oil Handling
•For this type of vehicle, it is recommended to use SW-100 type compressor oil. Use of PAG compressor
oil other than the SW-100 type may cause the A/C compressor to be damaged.
•During the operation, please be noticed not to splash the SW-100 type compressor oil onto the vehicle
surface. Therefore, if this happens, please wipe it off immediately, otherwise the compressor oil will
damage the paint on the vehicle surface.
