Transmission's Proper Use and Care
1. Transmission's proper operation
1.1 Shift the gear gently, not excessively.
1.2 Do not start with high speed.
1.3 To avoid premature abrasion of the gear shift fork, do not rest your hand on the \
gear lever while driving.
2. Model number of the lubricant to be used:
GL-4 80W-90 (For China domestic model)
GL-4 75W-90 (For alpine region model)
GL-5 140 (For high-temperature region model)
Caution: Please only use the lubricant with model numbers specified by t\
he Great Wall Motor Co., Ltd.
Do not mix lubricants with different model numbers. Only fill with clean lubricant.
3. Areas of importance for new vehicle usage:
3.1 Before using a new vehicle, be sure to check the transmission and all exposed connectors and fastening
pieces, so as to avoid failure due to faulty installation or loose conne\
ctions.
3.2 Since the new vehicle is still in the run-in period, the transmission's lubricant should be replaced after 5000 km
distance.
4. Transmission three-level maintenance:
4.1 Transmission level-one maintenance: During the first level of maintenance, the liquid level of the lubricant
should be checked to ensure that it is up to the oil-filling mouth. Add more if insufficient. Excessive low
oil level can lead to ineffective lubrication, as well as burning of the bearings and gears. Excessive high oil
level, however, can overheat the transmission or cause oil to leak. In addition, during the first level of main-
tenance, the breather plug should be checked and cleaned. If the breather plug is clogged, internal pressure
will build up and oil will leak from the transmission.
4.2 Transmission level-two maintenance: The transmission's lubricant should be replaced the first time that the
vehicle undergoes the second level of maintenance. Clean the transmission with kerosene. The quality of the
lubricant should be inspected during the future second level of maintenance practises. The lubricant should
be replaced if diluted, gummy, or dirty.
4.3 Transmission level-three maintenance: During the third level of maintenance, it should be removed for in-
spection, cleaning, and oil changing.

Functional description and display program
1. This system will be activated within the first second after engaging the reverse gear. There will be two
beeps indicating the system is working properly.
2. After the self-check, it will start its normal detection mode. The relationship between the obstacle
distance and the alarm frequency is as follows:
A Zone: When it is a long sounding alarm, the obstacle is within the distance of (0-40±4) cm.
B Zone: When the alarm frequency is an 8 Hz continuous sound, the obstacle is within the distance of
(40±4-90±4) cm.
C Zone: When the alarm frequency is a 4 Hz intermittent sound, the obstacle is within the distance of (90±4-
150±4) cm.
Areas of importance
1. When placed near a car equipped with the same system or a similar system (having been activated)
offered by other suppliers, though this system may receive interference, i\
t can still operate normally.
2. When the relative rate of travel between the obstacle and the car is lower than 1 m/s, this system will
operate as normal. When reverse speed is accelerated, the sensing accuracy of the reverse system
may decrease. A low speed of 6 km/h is suggested.
3. When it is a long sounding alarm, please stop the car at once, because there may be an obstacle
within 40cm.
4. The inductor precision level is high. It will be very difficult to return it to normal after opening the inner
portion.
5. The reflected signal may not be received due to the location, angle, size, or material of the object.
Furthermore, the reflected signal in a complex environment may not be ac\
curate.
System malfunction causes and solutions
1. A lack of power or a low supply voltage may lead to the abnormal operation of the reverse sensor
system. Under such circumstances, check whether the supply battery voltage is normal, or whether
the ignition switch connector and other connections are accurately place\
d.
2. If the power supply is on, irregular system operation may be caused by the incorrect position of the
socket. Under such circumstances, correctly re-place all the sockets.
3. A long sounding alarm from the buzzer may be caused by the inductor coming off, incorrect installa-
tion, damage to the inductor, or detecting the car or ground. Under such circumstances, please repair
or replace the sensor.
4. Incorrect indication of an obstacle's distance may be caused by abnormal battery voltage, inaccurate
socket positioning, or inductor connection damage. At this time, check whether the battery voltage
is normal, and whether the inductor connection is connected to the exhaust pipe and muffler. It is
suggested that the system be turned off and all the sockets be correctly placed.

Air Conditioning System's Structure Diagram and Fundamentals
Air Conditioning System Overview
Basic composition
Composed of air conditioner, compressor assembly, condenser
assembly, pipeline, defroster system, heating & ventilation
system, etc. The air conditioner also includes evaporator and
blower components.
Function
This system is a manually controlled air conditioning
system, with steam compression as its cooling method.
Residual heat water warming is the heating method the
engine adopts. Inner & outer circulation, blowing mode,
and cold & warm temperature adjustment are all controlled
by individual cables from the air conditioning controller. It
achieves ventilation, warming, and cooling integration.
Caution: While starting the compressor, you must open
the air regulation knob first, otherwise it cannot start.
Operation
The compressor is driven directly by the engine. High
temperature and high pressure refrigerant vapor exhausted
from the compressor will pass through the high pressure
pipe into the condenser, dissipate the heat via temperature
difference, and then form a high pressure liquid. High
pressure liquid passes through the accumulating dehydrator
into the expansion valve, and after passing through the
throttle valve, it becomes a low pressure liquid. Heat
exchange via the evaporator will cool down the room’s air,
and then the refrigerant inside the system will become a low
temperature and low pressure vapor, which is then sucked
into the compressor and compressed into high temperature
and high pressure air again. Thus a cooling cycle is formed.
The circulation continues, which maintains a comfortable
temperature inside the vehicle.

5. When charging the refrigerant, carefully observe the
high pressure side of the manifold pressure gauge as
well as the refrigerant's rate of flow (limpid, foamy, hazy)
which can all be seen from the inspection window. Use
this window to determine the appropriate time to stop
charging the refrigerant (by closing the low pressure
valve).
When the compressor is operating, please do not close the
high pressure valve.
Before inspecting the cooling level, confirm the regulated
refrigerant charge quantity for the air conditioning system.
Determine the charge amount for the refrigerant charge.
Please carry out the setup according to the following
working conditions.
Engine's water tank temperature: steady
Engine speed: normal idle
A/C switch: ON
Blower speed control switch: highest gear
Temperature controller: inner circulation
Door: completely open
Window: completely open
Filling Quantity and Method for Refrigerant Oil
First vacuum the refrigerant system to 0.2 × 10-5 Pa, then fill it with model number RS20 refrigerant. The steps
are as follows:
1. Close the high pressure, manually operated valve and the auxiliary valve\
.
2. Remove the high pressure side's hose from the manifold pressure gauge an\
d insert it into the oil cup.
3. Open the auxiliary valve and draw the refrigerant from the oil cup to th\
e refrigeration system.
4. When refrigerant in the oil cup is about to be fully vacuumed, immediately close the auxiliary valve, in
order to avoid sucking air into the system.
5. Screw the high pressure side hose connector onto the manifold pressure gauge, start the vacuum
pump and open the high pressure, manually operated valve, then open the auxiliary valve to vacuum
the system until it reaches 0.2 × 10-5 Pa, and continue to vacuum for 15 minutes to exhaust the air
which is entering the system following the oil.
Caution: When replacing an old compressor with a new one, be sure to bleed out some oil in order to
level off the new and the old compressor's oil level, and to avoid an excessive oil amount influencing
the cooling effect. When using an old or repaired compressor, be sure to keep the refrigerant inside
the compressor the same level as the one that is being replaced.
Daily Maintenance of the Air Conditioning System
In order to guarantee the air conditioning system's normal operation, regular maintenance should be performed.
Daily maintenance for the air conditioning system is as follows:
1. Inspect and clean the air conditioning system's condenser. The cooling fin's insides need to be
cleaned, with no blockage in between. After driving in the rain or on a muddy road, check the
condenser fan for silt or rocks. If any are found, immediately clean the\
m up.
2. Inspect the refrigeration system's refrigerant amount: When the air conditioning unit is operating
normally, observe the oil check glass. Under normal conditions, the oil check glass should have no air
bubbles.
3. Inspect the drive belt. The belt between the compressor and the decoration cover should be tight\
.
4. Check the air conditioning system to make sure there is no irregular noi\
se or unusual odors.
5. Check the compressor's inlet and exhaust port areas to make sure the tem\
perature is normal.
6. Check to make sure the appearance of the refrigeration system's hose is correct and that all the
connections are firm.
7. Inspect if the refrigeration system's pipelines run into other components, and any traces of leaking oil
at each connection.
8. Check and make sure the refrigeration system's circuit connector is firm, and any sign of circuit
disconnection.
9. Inspect if the compressor's fastening bolts are sturdy, reliable or flawed.
